Individual cognitive style affects flood‐risk perception and mitigation intentions
Abstract
Risk perception of natural hazards has been widely studied as one of the potential determinants of people's behaviors and behavioral intentions. However, individual differences can also affect risk perception. The present work focused on the link between an individual cognitive mindset (i.e., level of holism) and flood‐risk perception. It also assessed the consequences of such a link on public and personal mitigation intentions, taking into account the sense of connection with the environment, the psychological distance from the adverse event, and the role played by previous personal experience with flooding. Our study (N = 191) showed that the individual cognitive style predicted risk perceptions and personal (for both experienced and no‐experience groups) and public (only for experienced group) mitigation intentions, through the mediation of the sense of connection with the environment and the psychological distance from the adverse event. Results are discussed in terms of their practical implications for public communication and policies about environmental hazards.
... There is an extensive body of literature demonstrating how distance affects individuals' risk perception and behavior [32]. According to the PTE effect theory, people who are closer to the center of an adverse event are less concerned or fearful about the event. ...
... Therefore, spatial distance (i.e., supply chain distance) was measured by asking "My company's 'position' in the ZTE's supply chain network determines we are far from ZTE's disruption" (PD1). The items used to measure temporal and social distance were based on Spaccatini et al.'s work [32], and the item used to measure the hypotheticality of ZTE's supply chain disruption was based on Ellis et al.'s work [37]. Social distance was measured with "ZTE's supply chain disruption will have a little impact on my company" (PD2). ...
Previous research has shown that an individual’s proximity to the epicenter can influence their perception and response to risk. However, this aspect has been largely overlooked in the supply chain risk literature. This paper aims to fill this gap by investigating the impact of distance on the perception and response to supply chain disruption risk. An online survey was conducted with 1055 managers working within the supply chain of ZTE, a Chinese multinational company providing integrated communications and information solutions. The survey aimed to examine how their distance from the disruption epicenter (i.e., ZTE) affected their risk perception and subsequent managerial responses. The findings indicate that those closer to the epicenter perceive a lower risk of disruption compared to those farther away, resulting in a reduced likelihood of taking management action. This phenomenon is referred to as the “psychological typhoon eye” (PTE) effect in supply chain disruption risk. Further analysis revealed that risk information quality mediated the relationship between distance and risk perception, while an individual’s job position level moderated the relationship between risk information quality and disruption risk perception. To mitigate the PTE effect in the multi-tier supply chain, the focal firm must prioritize high-quality information synchronization, extending beyond single-company initiatives.
... Throughout different operationalizations, recent research provided insights about the relevance of the cognitive mindset on environmental cognition (e.g., Davis & Stroink, 2015;Lezak & Thibodeau, 2016;Sacchi et al., 2016;Spaccatini et al., 2021). For instance, systems thinkers, people who hold a mindset based on interrelation among elements (i.e., for a detailed definition, see Davis & Stroink, 2015), possessed a stronger sense of connection with nature, perceived the environmental risk as higher, expressed more support to sustainable policies, and attributed greater value to the ecosystem than non-systems thinkers (Davis & Stroink, 2015;Lezak & Thibodeau, 2016). ...
... In particular, people mentally construe a psychologically close stimulus by focusing on feasibility (low-level construal) and psychologically distant stimulus by focusing on general purpose (high-level construal). Both cognitive mindsets and CLT have been adopted to study environmental cognition (e.g., Griffioen et al., 2019;Reczek et al., 2018;Ryoo et al., 2017;Sacchi et al., 2016;Spaccatini et al., 2021). Research showed that holistic cognitive mindset and high-level construal are related to more environmental concerns, pro-environmental intentions, and purchase intentions for eco-friendly products (Davis & Stroink, 2015;Griffioen et al., 2019;Lezak & Thibodeau, 2016;Reczek et al., 2018). ...
Research literature about the environmental spillover effect produced mixed results, revealing that an initial pro-environmental behavior (PEB) is likely to promote either other PEBs (i.e., positive spillover) or pro-environmental inactions and harming behaviors (i.e., negative spillover). Such inconsistency suggests a possible crucial role of moderating variables. In two experimental studies (N Study 1 = 141, N Study 2 = 124), we investigated whether the recall of past environmental behavior (water-saving vs. water-wasting) affects future intention to perform PEBs (Study 1) and actual PEBs (Study 2), depending on participants’ cognitive mindset (manipulated in Study 1 and measured in Study 2). Results showed that the cognitive mindset is a significant moderator of spillover effects. Compared to a holistic one, an analytical mindset is more likely to result in a greater willingness to engage in future PEBs (Study 1) and actual PEB (Study 2) when past PEB is salient. The main contributions of the studies, limitations and possible future research directions are discussed.
... A review of psychological theories influencing adaptation behaviors shows how belief systems (including locus of control and self-efficacy) influence decision-making in risk environments (Rose et al., 2012). Spaccatini et al. (2021) consider the role of individual differences and examine relationships between individual cognitive mindset and perception, and mitigation intention relating to flood risk. In relation to vulnerability, Babcicky and Seebauer (2021) argue for including psychological factors in identifying those most vulnerable to floods, given their higher explanatory value for intangible outcomes, based on survey data of 1127 households living in flood-prone areas in Austria. ...
Water security as a concept recognizes the profound connections between the physical and social aspects of water. Yet, water security research features limited perspectives from two disciplines directly concerned with human behavior—the behavioral and psychological sciences. This review aims to characterize the main areas of research on water (including floods and droughts) which do feature concepts and methods from the behavioral and psychological sciences, discuss knowledge gaps, and draw attention to their potential to contribute to water‐related research. Bibliometric mapping of published water research identifies five research clusters and associated sub‐clusters: risk perception and flood, climate change and drought, water quality and water conservation, drinking water and bottled water, and mental health and WASH. A summary of research in each cluster and sub‐cluster highlights the application of many conceptual frameworks and behavioral determinants associated with water‐related behavior. Few articles focus on the role of governance or structural factors, and studies in low‐ and middle‐income countries are less represented in some clusters. The discussion considers the scope to apply higher level organizing frameworks for structuring behavioral and psychological science applications in water security and for exploring synergies with the physical and wider social sciences. In conclusion, further engagement with behavioral and psychological science within, between, and beyond the clusters identified here, could potentially deepen understanding of human–water interactions and enhance the design of measures to promote water security.

... Today, this construct plays a key role in cross-cultural research [e.g., [8][9][10] but it is applied also in research on consumer behaviour [11], marketing [12], creativity [13], brain responses [14], perception of risk [15], information sciences [16] or even donation decisions during COVID-19 pandemic [17]. ...
Cognitive styles are commonly studied constructs in cognitive psychology. The theory of field dependence-independence was one of the most important cognitive styles. Yet in the past, its measurement had significant shortcomings in validity and reliability. The theory of analytic and holistic cognitive styles attempted to extend this theory and overcome its shortcomings. Unfortunately, the psychometric properties of its measurement methods were not properly verified. Furthermore, new statistical approaches, such as analysis of reaction times, have been overlooked by current research. The aim of this pre-registered study was to verify the psychometric properties (i.e., factor structure, split-half reliability, test-retest reliability, discriminant validity with intelligence and personality, and divergent, concurrent and predictive validity) of several methods routinely applied in the field. We developed/adapted six methods based on self-report questionnaires, rod-and-frame principles, embedded figures, and hierarchical figures. The analysis was conducted on 392 Czech participants, with two data collection waves. The results indicate that the use of methods based on the rod-and-frame principle may be unreliable, demonstrating no absence of association with intelligence. The use of embedded and hierarchical figures is recommended. The self-report questionnaire used in this study showed an unsatisfactory factor structure and also cannot be recommended without futher validation on independent samples. The findings also did not correspond with the original two-dimensional theory.
... Our findings show how physical cues (e.g., damage or destruction of homes, businesses, and infrastructure) and psychological variables (e.g., stress, coping, and posttraumatic growth in response to the disaster) are associated with climate change risk perception [10,42,43]. The findings support research showing that affective responses may serve as a motivating factor such that people are more likely to take protective action to mitigate damage and threat exposure when they perceive a threat is likely and if mitigation efforts will be effective and practical [44,45]. ...
Background:
This two-study paper developed a climate change risk perception model that considers the role of posttraumatic growth (i.e., a reappraisal of life priorities and deeper appreciation of life), resource loss, posttraumatic stress, coping, and social support.
Method:
In Study 1, participants were 332 persons in the Philippines who experienced Super Typhoon Haiyan. In Study 2, participants were 709 persons in Fiji who experienced Cyclone Winston. Climate change can increase the size and destructive potential of cyclones and typhoons as a result of warming ocean temperatures, which provides fuel for these storms. Participants completed measures assessing resource loss, posttraumatic stress, coping, social support, posttraumatic growth, and climate change risk perception.
Results:
Structural equation modeling was used to develop a climate change risk perception model with data collected in the Philippines and to confirm the model with data collected in Fiji. The model showed that climate change risk perception was influenced by resource loss, posttraumatic stress, coping activation, and posttraumatic growth. The model developed in the Philippines was confirmed with data collected in Fiji.
Conclusions:
Posttraumatic growth played a central role in climate change risk perception. Public health educational efforts should focus on vividly showing how climate change threatens life priorities and that which gives life meaning and can result in loss, stress, and hardship. Disaster response organizations may also use this approach to promote preparedness for disaster threats.
... Adaptation and mitigation consist of both individual behaviors and structural protection measures. Research has abundantly investigated both mitigation (e.g., investing in sandbags and supporting public mitigation policy) [e.g., 4,14,15,16] and adaptation (e.g., evacuating from hazards and purchasing insurance) [e.g., 4,17] measures that citizens can privately adopt. This literature has identified a range of psychological predictors of individual mitigation and adaptation behaviors, and risk perception has attracted most of the attention [e.g., for a review, see [4], for a recent meta-analysis, see [18]]. ...
The psychological perception of structural measures developed to respond to hydrogeological hazards is pivotal in determining their efficacy. In this regard, alongside the vast psychological literature on mitigation behaviors, there is a lack of research on psychological constraints related to adaptation infrastructures. To fill this gap, we investigated the role of attitudes toward such measures and their antecedents on risk perception. Based on the Solution Aversion Model, Study 1 (n = 194) showed that the more participants oppose the adaptation measures, the less they perceive the risk of flooding. Extending Study 1, Study 2 (n = 95) provided evidence that distrust in science predicts people's dislike and aversion toward adaptive measures, which in turn predicts the perception of hydrogeological risk. Finally, Study 3 (n = 250) revealed that for participants with a lower level of prior knowledge about adaptation measures, the lack of trust in science predicts more negative attitudes toward adaptation, which is associated with lower risk perception.
Extreme weather events including flooding can have severe personal, infrastructural, and economic consequences, with recent evidence pointing to surface flooding as a pathway for the microbial contamination of private groundwater supplies. There is a pressing need for increasingly focused information and awareness campaigns to highlight the risks posed by extreme weather events and appropriate subsequent post-event actions. To date, little is known about the presence, directionality or magnitude of gender-related differences regarding flood risk awareness and behaviour among private groundwater users, a particularly susceptible sub-population due to an overarching paucity of infrastructural regulation across many regions. The current study investigated gender-related differences in flood risk perception and associated mitigation behaviours via a cross-sectional, national survey of 405 (168 female, 237 male) private groundwater supply users. The developed survey instrument assessed socio-demographic profile, previous flood experience, experiential and conjectural health behaviours (contingent on previous experience), and Risk, Attitude, Norms, Ability, Self-regulation (RANAS) framework questions. Statistically significant gender differences were found between both 'Norm-Descriptive' and 'Ability-Self-efficacy' RANAS elements (p < 0.05). Female respondents reported a lower level of awareness of the need for post-flood action(s) (8.9% vs. 16.5%), alongside a perceived "lack of information" as a reason for not testing their domestic well (4.9% vs. 11.5%). Conversely, male respondents were more likely to report awareness of their well location in relation to possible contamination sources (96.6% vs. 89.9%) and awareness of previous water testing results (98.9% vs. 93.0%). Gender-related gaps exist within the studied private groundwater reliant cohort, a sub-population which has to date remained under-studied within the context of climate change and extreme weather events. Accordingly, findings suggest that gender-focused communication and education may represent an effective tool for protecting current and future generations of global groundwater users.
A growing focus is being placed on both individuals and communities to adapt to flooding as part of the Sendai Framework for Disaster Risk Reduction 2015–2030. Adaptation to flooding requires sufficient social capital (linkages between members of society), risk perceptions (understanding of risk), and self-efficacy (self-perceived ability to limit disaster impacts) to be effective. However, there is limited understanding of how social capital, risk perceptions, and self-efficacy interact. We seek to explore how social capital interacts with variables known to increase the likelihood of successful adaptation. To study these linkages we analyze survey data of 1010 respondents across two communities in Thua Tien-Hue Province in central Vietnam, using ordered probit models. We find positive correlations between social capital, risk perceptions, and self-efficacy overall. This is a partly contrary finding to what was found in previous studies linking these concepts in Europe, which may be a result from the difference in risk context. The absence of an overall negative exchange between these factors has positive implications for proactive flood risk adaptation.
Recent policy changes highlight the need for citizens to take adaptive actions to reduce flood‐related impacts. Here, we argue that these changes represent a wider behavioral turn in flood risk management (FRM). The behavioral turn is based on three fundamental assumptions: first, that the motivations of citizens to take adaptive actions can be well understood so that these motivations can be targeted in the practice of FRM; second, that private adaptive measures and actions are effective in reducing flood risk; and third, that individuals have the capacities to implement such measures. We assess the extent to which the assumptions can be supported by empirical evidence. We do this by engaging with three intellectual catchments. We turn to research by psychologists and other behavioral scientists which focus on the sociopsychological factors which influence individual motivations (Assumption 1). We engage with economists, engineers, and quantitative risk analysts who explore the extent to which individuals can reduce flood related impacts by quantifying the effectiveness and efficiency of household‐level adaptive measures (Assumption 2). We converse with human geographers and sociologists who explore the types of capacities households require to adapt to and cope with threatening events (Assumption 3). We believe that an investigation of the behavioral turn is important because if the outlined assumptions do not hold, there is a risk of creating and strengthening inequalities in FRM. Therefore, we outline the current intellectual and empirical knowledge as well as future research needs. Generally, we argue that more collaboration across intellectual catchments is needed, that future research should be more theoretically grounded and become methodologically more rigorous and at the same time focus more explicitly on the normative underpinnings of the behavioral turn.

The 2018 edition of the Report, the second dedicated to this topic, provides the updated overview on landslide and flood hazard throughout the country and presents the risk indicators related to population, families, buildings, industries and services, and cultural heritage.
The Report updates the national maps of the landslide hazard of the River Basin Plans - PAI and of the hydraulic hazard according to the Scenarios of Legislative Decree 49/2010 (implementation of the 2007/60/EC Floods Directive), realized by ISPRA through the harmonization and the mosaic of the hazard zones mapped by the District Basin Authorities.
Risk indicators are a useful tool to support risk mitigation policies.
Flooding is a major threat to the local communities in the UK, and the risks are increasing due to climate change. Encouraging homeowners to prepare for the consequences of catastrophic flooding is imperative. This study aims to examine the ways in which individuals’ risk perceptions and socio-cultural characteristics co-determine the preparedness for flood hazards. It is based on a social survey about household arrangements that can reduce the economic losses arising from flooding and enhance community resilience. A total of 485 responses were solicited from homeowners in England and Wales. Results confirm that the intention to act is socially motivated. This indicates the need for addressing the role of social networks and engagement with local community in enhancing community resilience to flooding. On the other hand, the effect of risk-related considerations is complicated. Perceived severity of flood damage is associated with intended actions, whereas risk characteristics are not. This implies that although providing relevant risk information to the public is crucial, appealing to the feelings of fears and uncertainties is less likely to be effective in driving actions for managing flood risks than has been usually assumed. The findings have practical implications for policy-making and climate risk communication.
Recruiting participants is a challenge for many health, medical and psychosocial research projects. One tool more frequently being used to improve recruitment is the social networking website Facebook. A systematic review was conducted to identify studies that have used Facebook to recruit participants of all ages, to any psychosocial, health or medical research. 110 unique studies that used Facebook as a recruitment source were included in the review. The majority of studies used a cross-sectional design (80%) and addressed a physical health or disease issue (57%). Half (49%) of the included studies reported specific details of the Facebook recruitment process. Researchers paid between 110 per completing participants (Mean=23.06). Among studies that examined the representativeness of their sample, the majority concluded (86%) their Facebook-recruited samples were similarly representative of samples recruited via traditional methods. These results indicate that Facebook is an effective and cost-efficient recruitment method. Researchers should consider their target group, advertisement wording, offering incentives and no-cost methods of recruitment when considering Facebook as a recruitment source. It is hoped this review will assist researchers to make decisions regarding the use of Facebook as a recruitment tool in future research.
Natural hazards, such as major flood events, are occurring with increasing frequency and inflicting increasing levels of financial damages upon affected communities. The experience of such major flood events has brought about a significant change in attitudes to flood-risk management, with a shift away from built engineering solutions alone towards a more multifaceted approach. Europe's experience with damaging flood episodes provided the impetus for the introduction of the European Floods Directive, requiring the establishment of flood-risk management plans at the river-basin scale. The effectiveness of such plans, focusing on prevention, protection, and preparedness, is dependent on adequate flood awareness and preparedness, and this is related to perception of flood risk. This is an important factor in the design and assessment of flood-risk management. Whilst there is a modern body of literature exploring flood perception issues, there have been few examples that explore its spatial manifestations. Previous literature has examined perceived and real distance to a hazard source (such as a river, nuclear facility, landfill, or incinerator, etc.), whereas this article advances the literature by including an objectively assessed measure of distance to a perceived flood zone, using a cognitive mapping methodology. The article finds that distance to the perceived flood zone (perceived flood exposure) is a crucial factor in determining flood-risk perception, both the cognitive and affective components. Furthermore, we find an interesting phenomenon of misperception among respondents. The article concludes by discussing the implications for flood-risk management.
Decades of research have sought to understand how disaster preparedness decisions are made. We believe one understudied factor is the impact of near-miss events. A near-miss occurs when an event (such as a hurricane or terrorist attack) has some non-trivial probability of ending in disaster (loss of life, property damage), but the negative outcome is avoided largely by chance (e.g., at the last minute, the storm dissipates or the bomb fails to detonate). In the first of two experiments, we study reactions to a hurricane threat when participants are told about prior near-miss events. We find that people with information about a prior near-miss event that has no negative consequences are less likely to take protective measures than those with either no information or information about a prior near-miss event that has salient negative information. Similar results have been shown in prior research, but we seek to understand people’s reasoning for the different reactions. We examine the role of an individual’s risk propensity and general level of optimism as possible explanatory variables for the “near-miss” effect. We find risk propensity to be stable across conditions, whereas general optimism is influenced by the type of prior near-miss information, so that optimism mediates how near-miss information impacts protective decisions. People who experience a potentially hazardous near-miss but escape without obvious cues of damage will feel more optimistic and take less protective action. In the second study, we test messages about the hazard’s risk and examine the impact of these messages to offset the influence of near-misses. We end by discussing the implications of near-misses for risk communication.
The goal of the present research was to examine the relationship between the cogni-tive paradigm systems thinking and an ecologically informed worldview, specifically the New Ecological Paradigm. One hundred and fifteen psychology undergraduate students completed an online questionnaire assessing systems thinking, ecological worldview, environmental value-orientation, connectivity to nature, and environmental behaviors. Results demonstrated that systems thinkers possess a stronger ecological worldview and sense of connectivity with nature, harbour biospheric environmental values, and engage in more pro-environmental behaviors than those scoring low on systems thinking. Furthermore, it was found that systems thinking both uniquely predicted and was predicted by the New Ecological Paradigm. Moreover, results demonstrated that systems thinkers are better able to acknowledge 'system membership' and possess a greater understanding of the characteristics of complex ecological systems and their mutual influence on social-economic domains.
Abstract:
The deteriorating state of the environment and global warming pose a serious and unprecedented threat to humanity. Yet, public response and personal behavior do not seem to reflect the proportion of such a threat. In the present research we explored possible reasons for this discrepancy. Past research has shown that people perceive events as more threatening based on their immediacy, certainty, or personal implications. Liberman and Trope (2008) developed the concept of "psychological distance," according to which more immediate events are seen as “closer in time,” more certain events as “closer in probability,” and events with greater potential for personal harm as “socially closer.” Adopting this concept, we examined whether environmental threats are perceived as psychologically distant and the possible influence of this on their perception of environmental threat severity. In a sample of 305 students, we found that (a) environmental threats were perceived as psychologically distant, i.e., as not highly probable, immediate, or potentially harmful to the individual, and (b) psychological distance strongly affected perceived severity of environmental threats and willingness to engage in pro-environmental behavior. The reasons for the psychological remoteness of environmental threats and possible approaches to cope with its implications are discussed
Studies of risk perception examine the judgements people make when they are asked to characterize and evaluate hazardous activities
and technologies. This research aims to aid risk analysis and policy-making by providing a basis for understanding and anticipating
public responses to hazards and improving the communication of risk information among lay people, technical experts, and decision-makers.
This work assumes that those who promote and regulate health and safety need to understand how people think about and respond
to risk. Without such understanding, well-intended policies may be ineffective.
Flood management decision-makers face significant challenges as the climate
changes. The perceptions of those affected by floods are critical to the successful implementation
of adaptation responses; risk perceptions are affected by how information is
communicated and, in turn, perceptions influence expectations on flood risk managers to
respond. The links between flood experience, risk perception, and responses by individual
households were examined in the Hutt Valley, New Zealand, through a household survey, a
workshop and interviews with local government practitioners. Two propositions were
tested: (1) that flood experience can influence flood risk perceptions; and (2) that flood
experience can stimulate increased risk reduction and adaptation actions where changing
climate risk is likely. Perceptions of responsibility for flood management were also
examined. The study found that previous flood experience contributes to heightened perception
of risk, increased preparedness of households, greater willingness to make
household-level changes, greater communication with councils, and more advocacy for
spatial planning to complement existing structural protection. Flood-affected households
had a stronger preference for central government and communities having flood risk
responsibilities, in addition to local government. Those who lacked experience were more
likely to be normalised to their prior benign experiences and thus optimistic about flood
consequences. These results suggest that harnessing positive aspects of experience and
communication of changing risk through engagement strategies could help shift the focus
from citizens’ expectation that governments will always provide protection, to a citizen–
local government–central government dialogue about the changing character of flood risk and its implications, and build a ‘risk conscious’ society in which ‘sharing and bearing’ is considered desirable.
Although research indicates that adoption of flood preparations among Europeans is low, only a few studies have attempted to explain citizens’ preparedness behavior. This article applies the Protective Action Decision Model (PADM) to explain flood preparedness intentions in the Netherlands. Survey data (N = 1,115) showed that hazard-related attributes (e.g., perceived efficacy in protecting persons) were positively correlated, but failed to show that resource-related attributes (e.g., perceived costs) were negatively correlated with preparedness intentions. Although respondents rated the hazard-related attributes as more important than the resource-related attributes, moderated regression failed to detect practically meaningful interaction effects. Risk perception was also positively correlated with preparedness intentions but explained less variance than did the hazard-related attributes. Among the demographic characteristics, only female gender was consistently correlated with higher risk perception and the hazard-related attributes. Finally, risk area was correlated with perceived flood likelihood and consequences as well as the hazard-related attributes. Implications are discussed.
Converging evidence from the behavioural and brain sciences suggests that the human moral judgement system is not well equipped to identify climate change — a complex, large-scale and unintentionally caused phenomenon — as an important moral imperative. As climate change fails to generate strong moral intuitions, it does not motivate an urgent need for action in the way that other moral imperatives do. We review six reasons why climate change poses significant challenges to our moral judgement system and describe six strategies that communicators might use to confront these challenges. Enhancing moral intuitions about climate change may motivate greater support for ameliorative actions and policies.
The authors hypothesize that environmental values derive from a sense of connectivity with nature. Connectivity describes a perception of sameness between the self, others, and the natural world. The experience of connectivity involves dissolution of boundaries and a sense of a shared or common essence between the self, nature, and others. Connectivity with nature differs theoretically and operationally from other explanations of environmental values, including cultural bias, postmaterialism, and social altruism. The authors describe their development of a sociometric scale to operationalize connectivity with nature. Based on data from a mail survey of Pennsylvania landowners, the authors use multiple regression analyses to determine the extent to which connectivity with nature predicts and explains environmental concern and behavior in the presence of standard sociodemographic variables. Survey respondents reported a high level of connectivity with nature, and connectivity retained a significant and positive relationship to environmental concern and environmental behavior in multiple regression models. Implications of these findings are advanced.
Data from 23 studies confirm theoretical predictions that households’ adoption of earthquake hazard adjustments is correlated with their perceptions of the hazard and alternative adjustments, demographic characteristics, and social influences. However, some findings require modification of existing theories of hazard adjustment. Examination of the methods used in previous investigations underscores a need for better theories, more complete testing of existing theories, and improved data analytic and data reporting procedures in future tests of those theories.
This article reviews the main insights from selected literature on risk perception, particularly in connection with natural hazards. It includes numerous case studies on perception and social behavior dealing with floods, droughts, earthquakes, volcano eruptions, wild fires, and landslides. The review reveals that personal experience of a natural hazard and trust-or lack of trust-in authorities and experts have the most substantial impact on risk perception. Cultural and individual factors such as media coverage, age, gender, education, income, social status, and others do not play such an important role but act as mediators or amplifiers of the main causal connections between experience, trust, perception, and preparedness to take protective actions. When analyzing the factors of experience and trust on risk perception and on the likeliness of individuals to take preparedness action, the review found that a risk perception paradox exists in that it is assumed that high risk perception will lead to personal preparedness and, in the next step, to risk mitigation behavior. However, this is not necessarily true. In fact, the opposite can occur if individuals with high risk perception still choose not to personally prepare themselves in the face of a natural hazard. Therefore, based on the results of the review, this article offers three explanations suggesting why this paradox might occur. These findings have implications for future risk governance and communication as well as for the willingness of individuals to invest in risk preparedness or risk mitigation actions.
Flood risk management in the Netherlands is on the eve of shifting primarily from prevention towards risk management, including disaster preparedness and response and citizen participation. This study explores Dutch households' perceived responsibility for taking private protection measures. Survey results (n = 658) indicate that flood risk perception is low, that 73% of the respondents regard the government as primarily responsible for protection against flood damage, but that about 50% viewed disaster preparedness as an equal responsibility between themselves and the government. Thus, a substantial part of the public may have an open attitude to communication about disaster preparation measures. Dilemmas for increasing citizen participation are discussed.
People in different cultures have strikingly different construals of the self, of others, and of the interdependence of the 2. These construals can influence, and in many cases determine, the very nature of individual experience, including cognition, emotion, and motivation. Many Asian cultures have distinct conceptions of individuality that insist on the fundamental relatedness of individuals to each other. The emphasis is on attending to others, fitting in, and harmonious interdependence with them. American culture neither assumes nor values such an overt connectedness among individuals. In contrast, individuals seek to maintain their independence from others by attending to the self and by discovering and expressing their unique inner attributes. As proposed herein, these construals are even more powerful than previously imagined. Theories of the self from both psychology and anthropology are integrated to define in detail the difference between a construal of the self as independent and a construal of the self as interdependent. Each of these divergent construals should have a set of specific consequences for cognition, emotion, and motivation; these consequences are proposed and relevant empirical literature is reviewed.

This research investigates the antecedents of psychosocial impacts of the TMI nuclear power plant accident. A model of factors that are hypothesized to affect impact levels is developed and configured to approximate a hypothetical causal sequence. Using data from the Nuclear Regulatory Commission telephone survey, the technique of path analysis is used to test relationships in the model. The results show that the antecedents explain 12% of the variance in individual stress, 45% of the variance in family disruption, and 16% of the variance in perceived community change. The analysis shows that the TMI specific attitudes and sensitivity to radiation risks are strong antecedents of impacts. Although general attitudes toward nuclear power have minor indirect effects, it appears that situational experiences with the accident are the major contributors toward explaining impact levels.
Climate change is a threat to human health and life, both now and in the future. Despite this, studies show that the public typically do not consider the issue a priority concern or a direct, personal threat. Furthermore, few are taking any preventive or protective action. Previous studies identify direct experience as a major influence on risk perception, learning and action. Drawing on such evidence, this paper focuses on the intangibility of climate change as a key impediment to personal engagement and explores whether relevant experiences of flooding and air pollution influence individuals' knowledge, attitudes, risk perception and behavioural responses to climate change. Perhaps surprisingly, interviews and a survey conducted in the south of England indicate flood victims differ very little from other participants in their understanding of and responses to climate change, but that experience of air pollution does significantly affect perceptions of and behavioural responses to climate change. Air pollution victims are no more likely to cite pollution as a cause of climate change than non?victims; but they do have higher pro?environmental values. Respondents with these values are significantly more likely to consider climate change a salient risk and to take action in response to it. Therefore the relationship between air pollution experience and responses to climate change may be indirect and mediated by environmental values. The paper concludes by highlighting implications of this research for developing climate change policies and strategies for public engagement.
It should come as no surprise that the governments and citizenries of many countries show little concern about climate change and its consequences. Behavioral decision research over the last 30 years provides a series of lessons about the importance of affect in perceptions of risk and in decisions to take actions that reduce or manage perceived risks. Evidence from a range of domains suggests that worry drives risk management decisions. When people fail to be alarmed about a risk or hazard, they do not take precautions. Recent personal experience strongly influences the evaluation of a risky option. Low-probability events generate less concern than their probability warrants on average, but more concern than they deserve in those rare instances when they do occur. Personal experience with noticeable and serious consequences of global warming is still rare in many regions of the world. When people base their decisions on statistical descriptions about a hazard provided by others, characteristics of the hazard identified as psychological risk dimensions predict differences in alarm or worry across different classes of risk. The time-delayed, abstract, and often statistical nature of the risks of global warming does not evoke strong visceral reactions. These results suggest that we should find ways to evoke visceral reactions towards the risk of global warming, perhaps by simulations of its concrete future consequences for people's home or other regions they visit or value. Increased concern about global warming needs to solicited carefully, however, to prevent a decrease in concern about other relevant risks. The generation of worry or concern about global warming may be a necessary but not sufficient condition for desirable or appropriate protective or mitigating behavior on part of the general public.
Although the risk of flooding poses a serious threat to the Dutch public, citizens are not very inclined to engage in self-protective
behaviors. Current risk communication tries to enhance these self-protective behaviors among citizens, but is nonetheless
not very successful. The level of citizens engaging in self-protective actions remains rather low. Therefore, this research
strives to determine the factors that might enhance or lessen the intention to engage in self-protection among citizens. The
study was a 2 (flood risk: high vs low)×2 (efficacy beliefs: high vs low) between subject experiment. It was conducted to
test how varying levels of flood risk and efficacy beliefs influence two different self-protective behaviors, namely information
seeking and the intention to engage in risk mitigating or preventive behaviors. Furthermore, the relationship between information
seeking and the intention to take self-protective actions was discussed. Results showed that high levels of flood risk lead
to higher levels of both information seeking and the intention to engage in self-protective behaviors than low levels of flood
risk. For efficacy beliefs, the same trend occurred. Also, results showed that information seeking seems to coincide with
the intention to take preventive actions and acted as a mediator between the levels of perceived risk and efficacy and the
intention to take self-protective actions.

Five studies assessed the validity and reliability of the connectedness to nature scale (CNS), a new measure of individuals’ trait levels of feeling emotionally connected to the natural world. Data from two community and three college samples demonstrated that the CNS has good psychometric properties, correlates with related variables (the new environmental paradigm scale, identity as an environmentalist), and is uncorrelated with potential confounds (verbal ability, social desirability). This paper supports ecopsychologists’ contention that connection to nature is an important predictor of ecological behavior and subjective well-being. It also extends social psychological research on self–other overlap, perspective taking, and altruistic behavior to the overlap between self and nature. The CNS promises to be a useful empirical tool for research on the relationship between humans and the natural world.
Do individuals’ perceptions of their interdependence with the natural environment affect their environmental behaviors? From the perspective of interdependence theory, we introduce a scale to measure commitment to the natural environment. In Study 1, higher levels of commitment to the environment and greater inclusion of nature in the self separately predicted higher levels of pro-environmental behavior, even when controlling for social desirability and ecological worldview. In Study 2, participants primed to experience high commitment to the environment reported greater levels of pro-environmental behavioral intentions as well as pro-environmental behavior relative to participants primed to experience low commitment to the environment. Commitment to the natural environment is a new theoretical construct that predicts environmental behavior.
We discuss a cross-national pilot study in Sweden and the UK examining young people's environmental concerns and their perceptions of the causes and solutions. The study demonstrates that evaluations of the causes of environmental degradation are partly contingent upon the manner in which questions are framed leading to quite different interpretations of the findings. Moreover, attitudes also differ significantly between the British and the Swedish sample: in the UK environmental degradation is seen as more serious but also more distant from the respondents’ everyday experiences when answering pre-formulated questions. The causes of environmental degradation are located in both countries in government and industry policies promoting economic growth on the one hand. On the other, respondents identify distant developments in emerging economies as problems, without connecting their local experiences to the global effects they describe. In the open-ended part of the survey, individual behaviour is seen as the most important cause of environmental degradation. But while British respondents describe individuals as selfish, lazy and consumerist, Swedish respondents emphasise also structural causes like Western lifestyles and the market society. We present possible explanations for these differences and discuss the relationships between the global and the local in relation to constructions of the Other as well as the relationship of individualism and authoritarianism that emerge from the results.
Although organizations appear to learn from obvious failures, we argue that it is harder for them to learn from "near-misses"--events in which chance played a role in averting failure. In this paper, we formalize the concept of near-misses and hypothesize that organizations and managers fail to learn from near-misses because they evaluate such events as successes and thus feel safer about the situation. We distinguish perceived ("felt") risk from calculated statistical risk and propose that lower levels of perceived risk encourage people with near-miss information to make riskier subsequent decisions compared to people without near-miss information. In our first study, we confirm the tendency to evaluate near-misses as successes by having participants rate a project manager whose decisions result in either (a) mission success, (b) near-miss, or (c) failure. Participants (both students and NASA employees and contractors) give similar ratings to managers whose decisions produced near-misses and to managers whose decisions resulted in successes, and both ratings are significantly different from ratings of managers who experienced failures. We suggest that the failure to hold managers accountable for near-misses is a foregone learning opportunity for both the manager and the organization. In our second set of studies, we confirm that near-miss information leads people to choose a riskier alternative because of a lower perceived risk following near-miss events. We explore several alternative explanations for these findings, including the role of Bayesian updating in processing near-miss data. Ultimately, the analysis suggests that managers and organizations are reducing their perception of the risk, although not necessarily updating (lowering) the statistical probability of the failure event. We speculate that this divergence arises because perceived risk is the product of associative processing, whereas statistical risk arises from rule-based processing.
Despite scientific agreement about the anthropogenic cause of climate change, the general public holds different beliefs regarding the causes of climate change. Some believe climate change to be caused by natural processes, while others believe it to be caused by human activities. People’s beliefs regarding the causes of climate change drive both their risk perception and their mitigation behavior, and such beliefs are not easy to alter. Therefore, it is crucial to understand how these beliefs shape people’s perception of the consequences of climate change. We find that beliefs regarding the causes of climate change can lead to different perceptions of the possible consequences of climate change. People who believed climate change to be caused by human activities rather than by natural processes perceived the consequences of the 2017 hurricanes to be worse, as well as to cause more suffering, than people who believed climate change to be caused by natural processes. These results suggest a fallacy, since the suffering of people and animals affected by hurricanes does not depend on the causes of those hurricanes, but rather on the damage that is caused. With regard to communication, it is important to link the currently observable events possible caused by climate change to human behavior, since doing so may increase people’s awareness of the severity of the consequences of anthropogenic climate change and, thus, possibly also their willingness to engage in mitigation behavior and prevention measures.
Climate change (CC) poses severe threats to the agriculture sector in developing countries. Increasing empirical evidence has confirmed that adaptation strategies to CC at the farm level can significantly reduce the negative
impacts of CC and minimize vulnerability. Consequently, understanding adaptation to CC has become a major
concern for farmers to facilitate adaptation actions and assist them in improving their adaptive capacity. In this
context, this study investigated the most prominent psychological drivers of, and impediments to, adaptation
responses. To this end, 350 farmers from Kermanshah district in western of Iran were selected as our sample
through a multi-stage, stratified, random sampling method. Structural equation modeling found a complex relationship
between overall CC belief, risk perception, psychological distance, trust and risk salience, and farmers'
adaptation behaviors. Climate risk perception, trust, and psychological distance were much more effective in driving
farmers’ adaptation behaviors. The findings yield recommendations for public policy and risk communication
that could encourage adaptation behaviors among Iranian farmers
Cultural comparison has challenged people’s assumptions of universality in psychology. It has also revealed that many questions and approaches in psychology are not culture-free, but reflect a distinctively Western analytic framework. In this framework, the world is assumed to operate by discernible and stable rules, contradiction is a problem to be resolved, and entities are viewed as relatively independent agents. Context and relationships between people and objects are relatively downplayed—or, when they are examined, are assumed to operate under parsimonious rules. Dialectical or holistic thinking, a framework more prevalent in East Asian societies, involves greater attention to context and relationships, assumptions of change rather than stasis, and acceptance of contradiction. Analytic thinking is useful for science and daily life. But sometimes dialectical thinking results in more accurate conclusions or pragmatically useful decisions than analytic thinking. Therefore, we propose that both dialectical and analytic thinking should be consciously adopted as tools in the “cognitive toolbox” of researchers and laypeople alike. In the present article, we review the cross-cultural work demonstrating the psychological differences that analytic versus dialectical thinking produce. We then consider the strengths of each type of thinking and how they may serve complementary functions for problem solving.
Systems thinking is thought to facilitate complex decision-making, but relatively little is known about its psychological underpinning. We present three studies that situate a measure of the construct in relation to other dispositional measures that have received more attention in environmental psychology and by testing whether the mindset predicts behavior in a set of novel decision making tasks. In Study 1, we find that systems thinkers tend to believe in scientific consensus, recognize risks posed by climate change, and support policy interventions to address climate change; systems thinking was negatively related to conspiracist and free-market ideation. In Studies 2 and 3 we find that systems thinkers ascribe more value to the natural world — both in monetary terms as well as on social and ecological grounds. The findings suggest that models of environmental cognition can be improved by measuring peoples' tendency to engage in systems thinking.
Recent literature shows a negative relation between psychological distance of climate change and pro-environmental behavioral intentions: when climate change is perceived as a distant phenomenon in time and space, people are less prone to worry and, thus, to act. The present study explored under which conditions psychological distance proved to be effective on ecological attitudes. More specifically the research explored the interaction between climate change psychological distance and individual’s cognitive style (holistic vs. analytic) on pro-environmental attitudes. Across two studies, the results consistently showed that psychological distance is strongly related to environmental concerns when individuals adopt an analytic cognitive style. By contrast, when individuals are in a holistic mindset, psychological distance proved to be less effective on ecological attitudes and behavioral intentions. Taken together, our findings have relevant practical implications for environmental politics and communication strategies.
Many people perceive climate change as psychologically distant-a set of uncertain events that might occur far in the future, impacting distant places and affecting people dissimilar to themselves. In this study, we employed construal level theory to investigate whether a climate change communication intervention could increase public engagement by reducing the psychological distance of climate change. Australian residents (N = 333) were randomly assigned to one of two treatment conditions: one framed to increase psychological distance to climate change (distal frame), and the other framed to reduce psychological distance (proximal frame). Participants then completed measures of psychological distance of climate change impacts, climate change concern, and intentions to engage in mitigation behavior. Principal components analysis indicated that psychological distance to climate change was best conceptualized as a multidimensional construct consisting of four components: geographic, temporal, social, and uncertainty. Path analysis revealed the effect of the treatment frame on climate change concern and intentions was fully mediated by psychological distance dimensions related to uncertainty and social distance. Our results suggest that climate communications framed to reduce psychological distance represent a promising strategy for increasing public engagement with climate change.
Impacts of flooding are expected to increase, most notably in residential areas. As a consequence, private households are increasingly encouraged to engage in private flood mitigation complementary to public measures. Despite the growing literature on private flood mitigation, little is known about how social capital influences households’ perception of and coping with flood risks. This study draws on survey data of 226 flood-prone households in two Austrian Alpine municipalities, both recently affected by riverine flooding. We show that social capital cuts both ways: on the positive side, social capital increases perceived self-efficacy and provides critical support during and most notably after flood events. On the negative side, social capital reduces flood risk perceptions of private households. While social ties are effective when responding to and recovering from floods, the expectation of social support downplays risk, making precautionary action by households less likely. The results also show that flood-affected households receive more social support than they provide to others. In the long-run, this can lead to a problematic reciprocity imbalance, challenging the long-term stability of the interpersonal exchanges underlying social capital. Among the various sources of social support, informal social networks (neighbours, friends and relatives) provide the most important workforce in the response and recovery phase of a flood event. It is therefore crucial for flood risk management to recognise and promote the protective quality of social capital alongside conventional structural and non-structural measures.

Studies examining personal experiences of climate change-related events highlight the potential to encourage climate action by framing it as happening now, in your neighborhood, and affecting people like you - that is, psychologically close. We compare this literature to studies that examine psychological distance. The review reveals a disconnect: while studies of personal experience suggest merits of reducing psychological distance, other studies present a more nuanced picture in which psychological proximity does not always lead to more concern about or action on climate change. Despite its emphasis, psychological distance has not been widely studied in experimental work in the climate change context, and there is a need for more systematic examination of its effects across a range of mitigation and adaptation actions. Further, our review identifies potential pitfalls associated with decreasing psychological distance, such as fear and avoidance. Finally, we provide preliminary recommendations for optimal ways to bring climate change "home.".
Insights into flood mitigation behaviour are important because of the ongoing shift to risk-based flood management approaches in Europe and worldwide, which envisage a contribution from flood-prone households to risk reduction. The recent literature on factors that influence flood mitigation behaviour indicates that flood-coping appraisal is an important variable to understand and explain flood mitigation behaviour. Coping appraisal originates from Protection Motivation Theory (PMT), and refers to the cognitive process that people undergo when evaluating their own ability to avoid a certain risk. However, the empirical literature on the importance of coping appraisal is still scarce, and, in particular, little is known about the independent influence of the three single components of coping appraisal on precautionary behaviour: namely, response efficacy, self-efficacy, and response cost. This study presents the results of a recent survey among 752 flood-prone households along the river Rhine in order to provide detailed insights into the influence of the components of flood-coping appraisal on four different types of flood mitigation behaviour: structural building measures, adapted building use, the deployment of flood barriers, and the purchase of flood insurance. The results confirm that flood-coping appraisal is an important variable in terms of precautionary behaviour. In particular, both response efficacy and self-efficacy contribute to the models which explain the four different types of flood-mitigation behaviour. Based on these findings, it is concluded that risk communication should focus more strongly on the potential of flood-mitigation measures to effectively reduce or avoid flood damage, as well as on information about how to implement such measures in practice.
Humanity faces an unprecedented set of global environmental problems. We argue that to promote pro-environmental decisions and to achieve public consensus on the need for action we must address individual and collective understanding (cognition) of environmental problems, as well as individual and collective commitments to take action to mitigate or prevent those problems. We review literature pertaining to psychological predispositions, mental models, framing, psychological distance, and the social context of decisions that help elucidate how these goals of cognition and commitment can be achieved. This article reveals the complex and multiply determined nature of environmental decisions. However, we argue that this complexity points to opportunities to reduce the inherent uncertainty surrounding global environmental challenges via appeals to the psychological mechanisms that underpin our decisions.
Understanding public risk perception related to possible consequences of climate change is of paramount importance. Not only does risk perception have an important role in shaping climate policy, it is also central in generating support for initiatives for adaptation and mitigation. In order to influence public knowledge and opinion, there is a need to know more about why people have diverging attitudes and perceptions related to climate change and its possible consequences. By using representative survey data for Norway and multivariate analysis, the authors of this article show that differences in attitudes and perceptions are partially explained by factors such as gender, educational background, and people's political preferences. However, an important factor explaining people's perception of climate change and its possible consequences is their direct personal experience of damage caused by climate-related events such as flooding or landslide. Furthermore, the results show that personal experience of damage has the largest impact on the respondents' belief that there will be more natural-resource hazards locally than in Norway or globally. The results also show that merely living in a more exposed area but not having a personal experience of damage does not affect the respondents' concern towards climate change.
Disasters garner attention when they occur, and organizations commonly extract valuable lessons from visible failures, adopting new behaviors in response. For example, the United States saw numerous security policy changes following the September 11 terrorist attacks and emergency management and shelter policy changes following Hurricane Katrina. But what about those events that occur that fall short of disaster? Research that examines prior hazard experience shows that this experience can be a mixed blessing. Prior experience can stimulate protective measures, but sometimes prior experience can deceive people into feeling an unwarranted sense of safety. This research focuses on how people interpret near-miss experiences. We demonstrate that when near-misses are interpreted as disasters that did not occur and thus provide the perception that the system is resilient to the hazard, people illegitimately underestimate the danger of subsequent hazardous situations and make riskier decisions. On the other hand, if near-misses can be recognized and interpreted as disasters that almost happened and thus provide the perception that the system is vulnerable to the hazard, this will counter the basic “near-miss” effect and encourage mitigation. In this article, we use these distinctions between resilient and vulnerable near-misses to examine how people come to define an event as either a resilient or vulnerable near-miss, as well as how this interpretation influences their perceptions of risk and their future preparedness behavior. Our contribution is in highlighting the critical role that people's interpretation of the prior experience has on their subsequent behavior and in measuring what shapes this interpretation.
People may express high concern for global warming or environmental degradation, but when forced to evaluate the severity of environmental threats in relation to other threats, environmental threats are pushed to the bottom of the list. The present study was based on the premise that prioritizing threats involves, inter alia, hierarchizing the threats according to their perceived temporal proximity and since environmental threats are perceived, relative to other threats, as more temporally distant, they rank low. Future orientation (FO) is an individual-difference variable that describes the tendency to take into account temporally distant considerations. We predicted that environmental threats would be evaluated as more severe by individuals who were more future-oriented. The strongest effect of FO was found to be on concern about global warming and environmental degradation. This indicated that environmental threats were perceived as temporally farthest and, not surprisingly, received the lowest priority. External security threat was a top-priority; its severity evaluation was uncorrelated to FO, indicating that it was perceived as temporally closest. These evaluations significantly affected environmental attitudes and behavior. The implications on promoting environmental behavior in the presence of ever-existing shorter-term existential threats are discussed.
This article reports the first meta-analysis of the literature on protection motivation theory (Rogers, 1975, 1983; Rogers & Prentice-Dunn, 1997), a model of disease prevention and health promotion that has generated research for over two decades. The literature review included 65 relevant studies (N= approximately 30,000) that represented over 20 health issues. The mean overall effect size (d+= 0.52) was of moderate magnitude. In general, increases in threat severity, threat vulnerability, response efficacy, and self-efficacy facilitated adaptive intentions or behaviors. Conversely, decreases in maladaptive response rewards and adaptive response costs increased adaptive intentions or behaviors. This held true whether the measures were based on intentions or behaviors, and suggests that PMT components may be useful for individual and community interventions.
Recent research in risk perception has examined the role of affect and worldviews as orienting dispositions that guide people's decisions about complex and risky topics such as nuclear energy. This study tests and supports the hypothesis that worldviews and affect-laden imagery are highly predictive of perceptions of risk from nuclear power and support for that technology. Furthermore, affect and worldviews each contribute independently to the prediction of nuclear support. We find also that a person's affective imagery associated with nuclear power is systematically related to their worldviews. We conclude that affect and worldviews appear to play similar roles as orienting mechanisms, helping people navigate in a complex, uncertain, and sometimes dangerous world. The implication of this view for the practice of risk communication is briefly discussed.
Self-protective behavior by residents of flood-prone urban areas can reduce monetary flood damage by 80%, and reduce the need
for public risk management. But, research on the determinants of private households’ prevention of damage by natural hazards
is rare, especially in Germany. To answer the question of why some people take precautionary action while others do not, a
socio-psychological model based on Protection Motivation Theory (PMT) is developed, explaining private precautionary damage
prevention by residents’ perceptions of previous flood experience, risk of future floods, reliability of public flood protection,
the efficacy and costs of self-protective behavior, their perceived ability to perform these actions, and non-protective responses
like wishful thinking. The validity of the proposed model is explored by means of representative quantitative telephone surveys
and regression analyses, and compared with a socio-economic model (including residents’ age, gender, income, school degree
and being owner or tenant). Participants were 157 residents of flood-prone homes in Cologne, Germany, a city that has traditionally
been subject to minor and major flood events. Results of the study show the explanatory power of the socio-psychological model,
with important implications for public risk communication efforts. To motivate residents in flood-prone areas to take their
share in damage prevention, it is essential to communicate not only the risk of flooding and its potential consequences, but
also the possibility, effectiveness and cost of private precautionary measures.
Flood hazards are the most common and destructive of all natural disasters. For decades, experts have been examining how flood losses can be mitigated. Just as in other risk domains, the study of risk perception and risk communication has gained increasing interest in flood risk management. Because of this research growth, a review of the state of the art in this domain is believed necessary. The review comprises 57 empirically based peer-reviewed articles on flood risk perception and communication from the Web of Science and Scopus databases. The characteristics of these articles are listed in a comprehensive table, presenting research design, research variables, and key findings. From this review, it follows that the majority of studies are of exploratory nature and have not applied any of the theoretical frameworks that are available in social science research. Consequently, a methodological standardization in measuring and analyzing people's flood risk perceptions and their adaptive behaviors is hardly present. This heterogeneity leads to difficulties in comparing results among studies. It is also shown that theoretical and empirical studies on flood risk communication are nearly nonexistent. The article concludes with a summary on methodological issues in the fields of flood-risk perception and flood-risk communication and proposes an agenda for future research.
Differences in familiarity with food products may influence how information about the risks and benefits about foods is used in forming risk and benefit perceptions. In two experimental studies, the risk and benefit perceptions of student participants, for four foods (familiar or unfamiliar) were assessed. In experiment 1, participants had the option to voluntarily request information (N = 106). In experiment 2, participants were involuntarily exposed to varying amounts of risk and benefit information (N = 235). In the first experiment, risk and benefit perceptions for unfamiliar foods were the result of an ad hoc affect or attitude being formed from whatever information about a food was presented first. The second experiment confirmed these results. The asymmetry between risk and benefit perception can be understood in terms of prior attitude and primacy effects. The greater importance of risk information in the development of risk perception is shown, compared to the greater importance role of familiarity with foods for benefit perception. It is argued that risk and benefit perceptions associated with foods may be dependent on different psychological processes. Risk perception is more likely to be derived from deliberative information processing. Benefit perception is derived from heuristic information processing and personal experience.
Italy is a country highly vulnerable to floods and landslides. The present study aims to investigate disaster preparedness and perception of flood risk in a group of people living in an alpine valley in the north of Italy. Four hundred seven adult residents in nine communities exposed to hydrogeological risk were interviewed by using a structured questionnaire. Participants were asked about the adoption of a set of protective behaviors that can prevent negative consequences of floods. Perception of flood risk was assessed by means of a one-dimensional scale that was developed and validated by the authors. Items included in this scale asked participants to estimate likelihood of occurrence of different flood consequences and to express feelings of worry associated to them. Socio-demographic and experiential information on respondents were also collected. Overall, results showed that most of respondents were fairly well prepared to deal with a future flood disaster. Correlational and regression analyses indicated that disaster preparedness was positively associated with risk perception. In accordance with literature, there was not a significant relation between likelihood judgments and adoption of protective behaviors, while feelings of worry were associated with disaster preparedness. Authors interpret their results in relation to the socio-environmental characteristics of the studied communities. Theoretical, empirical and practical implications of the findings are also discussed.
In flood risk management, a shift can be observed toward more integrated approaches that increasingly address the role of private households in implementing flood damage mitigation measures. This has resulted in a growing number of studies into the supposed positive relationship between individual flood risk perceptions and mitigation behavior. Our literature review shows, however, that, actually, this relationship is hardly observed in empirical studies. Two arguments are provided as an explanation. First, on the basis of protection motivation theory, a theoretical framework is discussed suggesting that individuals' high-risk perceptions need to be accompanied by coping appraisal to result in a protective response. Second, it is pointed out that possible feedback from already-adopted mitigation measures on risk perceptions has hardly been considered by current studies. In addition, we also provide a review of factors that drive precautionary behavior other than risk perceptions. It is found that factors such as coping appraisal are consistently related to mitigation behavior. We conclude, therefore, that the current focus on risk perceptions as a means to explain and promote private flood mitigation behavior is not supported on either theoretical or empirical grounds.
