Introduction: Themultiple risks generated by the COVID-19 pandemic intensified the debate about healthcare access and coverage. Whether the burden of disease caused by the coronavirus outbreak changed public opinion about healthcare provision remains unclear. In this study, it was specifically examined if the pandemic changed support for government...

In 2002, a group of investigators joined forces to propose a new conceptual paradigm based on a cognitive approach to motivation. This approach, referred to as goal systems theory, offered a broad perspective on behavioral phenomena and inspired research programs in diverse domains of psychological science. The present volume collects the rich body...

Psychological research on the predictors of conspiracy theorizing - explaining important social and political events or circumstances as secret plots by malevolent groups - has flourished in recent years. However, research has typically examined only a small number of predictors in one, or a small number of, national contexts. Such approaches make...

One of the oldest scientific theories of human aggression is the frustration-aggression hypothesis, advanced in 1939. Although this theory has received considerable empirical support and is alive and well today, its underlying mechanisms have not been adequately explored. In this article, we examine major findings and concepts from extant psycholog...

Unemployment caused by the COVID-19 pandemic is of the utmost importance for governing bodies worldwide. Its constant increase during the last months is subject of major concern for both citizens and policy makers, as individuals might experience increased feelings of job insecurity due to the pandemic context and to the latest developments on the...

It is puzzling that a sizeable percentage of people refuse to get vaccinated against COVID-19. This study aimed to examine social psychological factors influencing their vaccine hesitancy. This longitudinal study traced a cohort of 2663 individuals in 25 countries from the time before COVID-19 vaccines became available (March 2020) to July 2021, wh...

Xenophobia and anti-immigrant attacks rose during the COVID-19 pandemic, yet this may not be solely due to the disease threat. According to theories of frustration and scapegoating, situational obstructions and deprivation can motivate prejudice against outgroups. Using a global natural quasi-experimental design, this study tests whether the restri...

Crises like the COVID-19 pandemic can trigger concerns about loss of employment and changes in work conditions, and thereby increase job insecurity. However, little is known about how perceived job insecurity subsequently unfolds over time and how individual differences in habitual coping moderate such a trajectory. Using longitudinal data from 899...

We examined age group differences in hedonic adaptation trajectories of positive and negative affect (PA/NA) at different arousal levels during the severe societal restrictions that governments implemented to contain the first wave of the COVID-19 pandemic (March to June 2020). Data from 10,509 participants from 33 countries and 12 weekly assessmen...

Background: We examined age group differences in hedonic adaptation trajectories of positive and negative affect (PA/NA) at different arousal levels during the severe societal restrictions that governments implemented to contain the first wave of the COVID-19 pandemic (March to June 2020). Method: Data from 10509 participants from 33 countries and...

The shifts-jumps-leaps (SJL) perspective of means substitution, accepted for publication in an edited book by Arie Kruglanski and others on goal systems theory research.

Before vaccines for COVID-19 became available, a set of infection prevention behaviors constituted the primary means to mitigate the virus spread. Our study aimed to identify important predictors of this set of behaviors. Whereas social and health psychological theories suggest a limited set of predictors, machine learning analyses can identify cor...

Even though the motivation to feel worthy, to be respected, and to matter to others has been identified for centuries by scholars, the antecedents, consequences, and conditions of its activation have not been systematically analyzed or integrated. The purpose of this article is to offer such an integration. We feature a motivational construct, the...

Understanding how individual beliefs and societal values influence support for measures to prevent SARS-CoV-2 transmission is vital to developing and implementing effective prevention policies. Using both Just World Theory and Cultural Dimensions Theory, the present study considered how individual-level justice beliefs and country-level social valu...

The current research examined the role of values in guiding people’s responses to COVID-19. Results from an international study involving 115 countries (N = 61,490) suggest that health and economic threats of COVID-19 evoke different values, with implications for controlling and coping with the pandemic. Specifically, health threats predicted prior...

During the initial phase of the COVID-19 pandemic, U.S. conservative politicians and the media downplayed the risk of both contracting COVID-19 and the effectiveness of recommended health behaviors. Health behavior theories suggest perceived vulnerability to a health threat and perceived effectiveness of recommended health-protective behaviors dete...

We examine how social contacts and feelings of solidarity shape experiences of loneliness during the COVID-19 lockdown in early 2020. From the PsyCorona database, we obtained longitudinal data from 23 countries, collected between March and May 2020. The results demonstrated that although online contacts help to reduce feelings of loneliness, people...

Cross-societal differences in cooperation and trust among strangers in the provision of public goods may be key to understanding how societies are managing the COVID-19 pandemic. We report a survey conducted across 41 societies between March and May 2020 (N = 34,526), and test pre-registered hypotheses about how cross-societal differences in cooper...

Background The effective implementation of government policies and measures for controlling the coronavirus disease 2019 (COVID-19) pandemic requires compliance from the public. This study aimed to examine cross-sectional and longitudinal associations of trust in government regarding COVID-19 control with the adoption of recommended health behaviou...

The COVID-19 pandemic presents threats, such as severe disease and economic hardship, to people of different ages. These threats can also be experienced asymmetrically across age groups, which could lead to generational differences in behavioral responses to reduce the spread of the disease. We report a survey conducted across 56 societies (N = 58,...

Background Although there are increasing concerns on mental health consequences of the COVID-19 pandemic, no large-scale population-based studies have examined the associations of risk perception of COVID-19 with emotion and subsequent mental health. Methods : This study analysed cross-sectional and longitudinal data from the PsyCorona Survey that...

The Coronavirus is highly infectious and potentially deadly. In the absence of a cure or a vaccine, the infection prevention behaviors recommended by the World Health Organization constitute the only measure that is presently available to combat the pandemic. The unprecedented impact of this pandemic calls for swift identification of factors most i...

The PsyCorona collaboration is a research project to examine processes involved in the COVID-19 pandemic, such as behavior that curbs virus transmission, which may implicate social norms, cooperation, and self-regulation. The study also examines psychosocial consequences of physical distancing strategies and societal lockdown, such as frustration o...

The purpose of this data visualization tool is twofold. First, it serves as a resource for researchers, analysts, and practitioners to understand people’s thoughts, feelings, and responses to the coronavirus as well as the extraordinary societal measures taken against it. Such knowledge could provide pilot data for researchers, inform current polic...

Significance Some mass shooters openly express intent to target ethnic and racial minorities, but members of the public still do not agree on whether the gunman was indeed motivated by prejudice and/or hatred. The present research finds that members of a dominant majority often express uncertainty about hate crimes when they privately sympathize wi...

Mapping the Moods of COVID-19: Global Study Uses Data Visualization to Track Psychological Responses, Identify Targets for Intervention

This paper examines whether compliance with COVID-19 mitigation measures is motivated by wanting to save lives or save the economy (or both), and which implications this carries to fight the pandemic. National representative samples were collected from 24 countries (N=25,435). The main predictors were (i) perceived risk to contract coronavirus, (ii...

Previous studies suggested that public trust in government is vital for implementations of social policies that rely on public's behavioural responses. This study examined associations of trust in government regarding COVID-19 control with recommended health behaviours and prosocial behaviours. Data from an international survey with representative...

When thwarted goals increase endorsement of violence, it may not always reflect antisocial tendencies or some breakdown of self-regulation per se; such responses can also reflect an active process of self-regulation, whose purpose is to comply with the norms of one's social environment. In the present experiments (total N = 2,145), the causal link...

Between 2016 and 2017, Americans suffered 3 of the deadliest mass shootings in modern history by a lone gunman: the Orlando nightclub shooting, the Las Vegas strip shooting, and the Texas church shooting. We studied American gun owners in the wakes of these tragedies, theorizing that a byproduct of the salience of mass shootings is to increase the...

Thwarted goals and motivational obstacles are antecedents of aggression, but it is not entirely clear what motivates the aggressive response or why it is often displaced onto unrelated targets. The present work applies Goal Systems Theory (Kruglanski et al., 2002) to consider how displaced aggression can sometimes operate like any other means to an...

Mass public shootings are typically followed by a spike in gun sales as well as calls for stricter gun control laws. What remains unclear is whether the spike in gun sales is motivated by increased threat perceptions or by concerns about gun control, or whether the sales are mainly driven by non-owners purchasing guns or gun owners adding to their...

Americans are the world’s best armed citizens and public polling suggests protection/self-defense is their main reason for gun ownership. However, there is virtually no psychological research on gun ownership. The present article develops the first psychological process model of defensive gun ownership—specifically, a two-component model that consi...

Intrinsic rewards are typically thought to stem from an activity's inherent properties and not from separable rewards one receives from it. Yet, people may not consciously notice or remember all the subtle external rewards that correspond with an activity and may misattribute some directly to the activity itself. We propose that perceptions of intr...

Psychological reactance is typically assumed to motivate resistance to controlling peer influences and societal prohibitions. However, some peer influences encourage behaviors prohibited by society. We consider whether reactant individuals are sensitive to such opportunities to enhance their autonomy. We specifically propose a self-regulatory persp...

Major depressive disorder (MDD) has been associated with abnormalities in speech and behavioural mimicry. These abnormalities may contribute to the impairments in interpersonal functioning that are often seen in MDD patients. MDD has also been associated with disturbances in the brain serotonin system, but the extent to which serotonin regulates sp...

Effective self-regulation could involve not only managing internal resources for goal pursuit but also the often-fleeting interpersonal resources that can support goal attainment. In five studies, we test whether people who are effective self-regulators tend to position themselves in social environments that best afford self-regulatory success. Res...

How do people react to indifference when they see it in others? In 5 studies we examined how people may respond to it as a cue to disengage when they lack sufficient commitment to a goal or task themselves. Across the studies, participants were either exposed to cues implying an absence of motivation or not, after which their own goal-directed moti...

If people's goals and evaluative standards were aligned, then individuals with mastery-based goals should, theoretically, primarily rely on temporal comparison information (i.e., on how they performed relative to before). In contrast, individuals with performance-based goals should rely on social comparison information (i.e., on how they performed...

Goal contagion is a process in which perceivers inadvertently "catch" goals inferred from others' behavior; yet, social perception is often driven by the broader contexts surrounding others-and these contexts may suffice to drive goal inferences and contagion on their own. In Study 1, context-driven goal contagion occurred merely from perceiving th...

In the research reported here, we investigated how suspicious nonverbal cues from other people can trigger feelings of physical coldness. There exist implicit standards for how much nonverbal behavioral mimicry is appropriate in various types of social interactions, and individuals may react negatively when interaction partners violate these standa...

Goal shielding theory suggests that one's focal pursuits automatically inhibit the activation of interfering goals (Shah, Friedman, & Kruglanski, 2002); however, it is not entirely clear how individuals come to identify what constitutes “interfering”. Three studies examine how this identification process may be guided by fundamental social motives...

Four studies demonstrate that the affiliative responding that is typically encouraged by mimicry can be manifested in conformity to shared gender and racial stereotypes. In Studies 1 and 2, mimicry by a confederate led participants to perform in accordance with stereotypes about their race and gender on a math task. Studies 3 and 4 tested the bound...

The implicit appeal of temptations may vary by the social and self-regulatory contexts in which they are encountered. In each of four studies, participants were subliminally primed with the name of someone associated with either drug use or drug abstinence, after which their own motives toward drug use were assessed. Results indicate that the appea...

In a randomized double-blind placebo-controlled experiment, 64 women and 26 men applied testosterone and placebo skin creams during two five- to seven-day periods. Subjects provided serum samples for testosterone assay, completed a daily affect measure, wrote projective stories, recorded random samples of everyday speech, provided a guess as to whi...

Dissertation Three studies examine individuals' implicit sensitivity to the absence of motivation perceived in others and how the nature of this sensitivity is moderated by individuals' own motivational states. Using a subliminal priming paradigm, Study 1 tested a direct perception-behavior link between perceiving indifference in others and applyi...
