Misinformation often involves sensitive topics, and individuals may attempt to correct their peers using uncivil tones. We examined the effect of civil versus uncivil corrections on the perceived success of the correction and the reported relationship consequences. We used three-wave panel data consisting of 1513 participants in the first wave, and...
The availability of online data has altered the role of social media. By offering targeted online advertising, that is, persuasive messages tailored to user groups, political parties profit from large data profiles to send fine-grained advertising appeals to susceptible voters. This between-subject experiment ( N = 421) investigates the influence o...
During early adolescence children are increasingly using their smartphones not only throughout the day, but also before or even during the nighttime. Prior research has revealed that children’s school performance might suffer because of late-night smartphone use. To gain a further understanding of the consequences of nighttime smartphone use on sch...
Reflective smartphone disengagement (i.e., deliberate actions to self-regulate when and how one should use one's smartphone) has become a necessary skill in our ever-connected lives, contributing to a healthy balance of related benefits and harms. However, disengaging from one's smartphone might compete with impulsive psychosocial motivators such a...
Swipe-based dating apps characteristically provide quantitative social feedback in the form of mattches. Surveys suggest a link between dating app success and well-being, but the nature of this correlation has yet to be examined. In an experiment with 125 undergraduate women, we manipulated dating app feedback: When accepting a profile, participant...
Targeted political advertising (TPA) on social media builds on tailoring messages to (groups of) individuals’ characteristics based on user data. Questions have been raised about the impact of TPA on recipients and society. In this study, we focus on the fit of TPA, that is, the congruence between TPA and recipients’ preferences, and draw on congru...
Background:
In modern audiovisual media, children are confronted with an endless stream of food advertising. Thus, companies can undermine parents' best efforts to feed their children healthy foods. Indeed, parents often describe that their children request specific foods depicted in media, most of which are high in fat, salt, and/or sugar.
Objec...
Studies showed adverse experiences related to the use of dating applications such as Tinder. However, it remains unclear by which mechanism and under which conditions dating app use has undesired effects. As a mechanism, we investigated excessive swiping, operationalized as youth’s mental preoccupation with profile browsing and swiping compulsivity...
Ghosting (i.e., terminating communication with another person on social media without explanation) has become an all-too-common occurrence. Prior scholarship has predominantly focused on adverse effects of being ghosted on individuals’ well-being and mainly investigated the phenomenon within romantic relationships. By contrast, its occurrence withi...
Given that terrorism is omnipresent on social media, it is imperative to study how seeing terror content online is related to individuals’ attitudes, behaviors, and emotions. This study investigates how exposure to terrorism on social media associates with terror-related online self-disclosure and how self-disclosure, in turn, relates to fear of te...
Given how strongly social media is permeating young people’s everyday lives, many of them have formed strong habits that, under specific circumstances, can spiral out of control and bring harmful experiences. Unlike in extant literature where habitual and compulsive behaviors are often conflated, we report findings from a two-wave panel study exami...
There are grounds to assume that the use nonpolitical, entertainment-oriented Social Media (SM) may dampen democratically relevant outcomes. However, research has largely ignored the political effects of such entertainment-oriented SM content as well as its interaction with exposure to political SM content. Based on the distinction between politica...
Data suggests that the majority of citizens in various countries came across ‘fake news’ during the COVID-19 pandemic. We test the relationship between perceived prevalence of misinformation and people’s worries about COVID-19. In Study 1, analyses of a survey across 17 countries indicate a positive association: perceptions of high prevalence of mi...
Political parties increasingly rely on sophisticated targeting strategies to persuade potential voters. However, questions have been raised about the effectiveness of targeted political ads, considering that citizens frequently oppose the use of their data for political purposes. In this study, we investigate three avoidance behaviors that citizens...
Uncivil campaigning and deceitful campaign techniques are increasingly relevant phenomena in politics. However, it remains unclear how they share an underlying component and how partisanship can influence their associations with democratic outcomes. We introduce the concept of dirty campaigning, which is situated at the intersection of research on...
Many adolescents and young adults spend countless hours a day on social media, where they can engage with social media influencers and may establish parasocial relationships (PSRs) with them. Recently, “green” influencers (“greenfluencers”), who post content on the topic of sustainability, have emerged. Yet, it is unclear whether adolescents' and y...
Mobile social media have become a widespread means to participate in everyday social and professional life. These platforms encourage the disclosure and exchange of personal information, which comes with privacy risks. While past scholarship has listed various predictors and consequences of online privacy concerns, there has been to date no empiric...
A widely believed claim is that citizens tend to selectively expose themselves to like-minded information. However, when individuals find the information useful, they are more likely to consume cross- cutting sources. While crises such as terror attacks and pandemics can enhance the utility of cross-cutting information, empirical evidence on the ro...
This article seeks to explain the longitudinal associations of taking the smartphone to bed on adolescents’ daytime tiredness and physical well-being. We examined whether parents’: (a) active mediation; and (b) restrictive mediation determines whether children and adolescents
have their phones within reach in bed or not. We used longitudinal data f...
Studies showed adverse psychological effects related to the use of dating applications such as Tinder. However, it remains unclear by which mechanism and in which conditions dating app use has undesired effects. As a mechanism, we investigated excessive swiping, operationalized as youth’s mental preoccupation with profile browsing and swiping compu...
Islamist terrorist attacks and existing terror threat can seriously affect intergroup relations and policy making. Drawing on hostile media effect theory and intergroup threat theory, we hypothesized that perceived threat of terror influences perceived news media bias in favor of Muslims as well as support for surveillance policies that are perceiv...
Employing a mobile experience sampling design, we investigated in the present study how different types of mobile social media use relate to young individuals’ momentary affective well-being and momentary loneliness. We differentiated between three types of social media use: Messaging, posting, and browsing. Moreover, we studied fear of missing out...
Social media influencers promote not only products and brands but also their opinions on serious topics like party politics or climate change. These so-called digital opinion leaders may exert a powerful impact on their followers’ political attitudes. Accordingly, we explore new directions to explain how influencers’ communication is related to pol...
With the increasing availability of big digital voter data, there are rising concerns that online political micro-targeting (PMT) may be harmful for democratic societies. However, PMT may also be beneficial to democracy because it targets voters with content that matches with their predispositions, potentially increasing political interest. For bot...
In the last two decades, communication research dedicated substantial attention to the effects of incidental exposure (IE) to political information. In this meta-analysis, we analyzed the relationship of IE and five outcomes relevant for democracies. Including 106 distinct samples with more than 100,000 respondents, we observed positive cross-secti...
Today, the internet and particularly social media offer lots of opportunities to encounter political information incidentally. Motivated by conflicting findings regarding the effects of incidental exposure (IE) on political outcomes, researchers recently developed new theoretical models. Building on the Political Incidental News Exposure (PINE) mod...
There are rising concerns that social network sites (SNS) facilitate the creation of echo chambers, in which attitude-consistent information becomes the norm while attitude-challenging information is avoided. This study aims to investigate theoretically derived predictors of attitude-consistent and attitude-challenging exposure on SNS. We theorize...
Political advertising on social media heavily capitalizes on the fact that citizens leave behind data traces through their online behaviors. Even though this allows parties to target citizens based on their age, gender, or even specific interests, there is often a mismatch between the parties and the individuals’ party preferences. This study inves...
Purpose
Scholars have expressed great hopes that social media use can foster the democratic engagement of young adults. However, this research has largely ignored non-political, entertainment-oriented uses of social media. In this essay, I theorize that social media use can significantly dampen political engagement because, by and large, young adul...
The COVID-19 pandemic is one of the biggest crises of the 21st century. This paper investigates the role of reactance-based perceptions of threatening government communication on (1) attitudinal outcomes regarding acceptance of the COVID-19 health protection measures and (2) behavioral outcomes regarding adherence to the COVID-19 measures. From a t...
When the COVID-19 pandemic began, in early 2020, lockdowns limited the options for physical intimacy and many resorted to technology-mediated forms of intimacy such as sexting. However, it is unclear what predicted willingness to engage in sexting during the lockdown. The present study filled this gap by investigating COVID-19-related social isolat...
This volume offers a wide range of insights into current media reception and effects research on the topic of ‘sustainability’. The contributions it contains deal with how this topic is communicated and negotiated on (social) media, how various message and context features affect sustainable behaviour, and what role established and ‘new’ actors—suc...
For many individuals, the media function as a primary source of information about preventative measures to combat COVID-19. However, a considerable number of citizens believe that the media coverage about pandemics is exaggerated. Although the perception of media exaggeration may be highly consequential for individual health behaviors, we lack rese...
Considering that insufficient sleep has long been regarded as a significant public health challenge, the COVID-19 pandemic and its co-evolving infodemic have further aggravated many people's sleep health. People's engagement with pandemic-related news, particularly given that people are now permanently online via smartphones, has been identified as...
Due to 'stay-at-home' measures, individuals increasingly relied on smartphones for social connection and for obtaining information about the COVID-19 pandemic. In a two-wave panel survey (N T2 = 416), we investigated associations between different types of smartphone use (i.e., communicative and non-communicative), friendship satisfaction, and anxi...
Alternative digital media typically provide a counter-public sphere by opposing the contents generated by the mainstream media as well as political elites. While previous research has mainly explained the usage of alternative digital media, we particularly lack research on its association with key political outcomes relevant to democracy. Using two...
Citizen science research has been rapidly expanding in the past years and has become a popular approach in youth education. We investigated key drivers of youth participation in a citizen social science school project and the effects of participation on scientific and topic-related (i.e., political) interest and efficacy. Findings suggest that fema...
While the role of social media in the spread of conspiracy theories has received much attention, a key deficit in previous research is the lack of distinction between different types of platforms. This study places the role of social media affordances in facilitating the spread of conspiracy beliefs at the center of its enquiry. We examine the rela...
The present paper develops a new concept, called Reflective Smartphone Disengagement (RSD), defined as individuals’ deliberate efforts to control and restrict smartphone use. Based on the reflective-impulsive model, we examined the RSD concept in four studies, using cross-sectional data of adolescents (Study 1, n = 453, Study 3, n = 760) and adults...
Background: Given that governmental prevention measures restricted most face-to-face communications, online self-disclosure via smartphones emerged as an alternative coping strategy that aimed at reducing the impact of the COVID-19 pandemic on people’s psychological health. Prepandemic research demonstrated that online self-disclosure benefits peop...
There is an abundance of evidence that the presentation of unhealthy foods (UHFs) in different media has the power to shape eating habits in children. Compared to this rich body of work with regard to the effects of UHF presentations, studies testing the effects of healthy foods (HFs) are less conclusive. In particular, while the persuasive mechani...
During the global COVID-19 pandemic, many people were physically separated from their romantic or sexual partners and added sexting to their sexual repertoire. Sexting involves the exchange of sensitive data and thus necessitates personal and interpersonal privacy management strategies such as information control and privacy boundary communication....
Dating apps advertise with high availability of potential partners because users seem to prefer extensive choice. However, on the basis of consumer decision making research, we theorized that such excessive choice could have adverse effects, specifically on fear of being single, self-esteem, and partner choice overload. In Study 1, a survey with 66...
Citizens’ misperceptions on critical issues such as climate change, migration, or health are viewed as a major problem in today’s democratic systems. A large body of literature shows how inaccurate information might lead to misperceptions despite of corrections and retractions. This study highlights individuals’ acts of resistance against journalis...
Influencer marketing is a very important marketing strategy that builds its success on the strong link between influencers and their followers. A recent change in legislation obligates influencers to disclose if they are posting promotional content. Some studies indicate that such disclosures might dampen positive attitudes toward the promoted prod...
Children are increasingly using their own smartphones for communicative and non-communicative purposes. In fact, studies showed that different ways of using the smartphone might influence loneliness, and as a consequence, loneliness might also enhance further engagement with the smartphone. In this context, parents play an important role because th...
Exogenous shocks like the COVID-19 pandemic unleashes multiple fundamental questions about society beyond public health. Based on the classical concept of ‘need for orientation’ and the literature on the role of the media in times of crisis, we investigate to what extent the COVID-19 pandemic affected news consumption in comparative perspective. Ba...
Promoting health-related behaviors such as healthy eating or doing sports are important to counteract the problem of obesity, which is on the rise. In this regard, initial studies suggest that appearance compared to health framing can lead to negative body-related outcomes in young women. This study aimed to extend these findings by investigating t...
Numbers can convey critical information about political issues, yet statistics are sometimes cited incorrectly by political actors. Drawing on real-world examples of numerical misinformation, the current study provides a first test of the anchoring bias in the context of news consumption. Anchoring describes how evidently wrong and even irrelevant...
Kinder werden mit einer Vielzahl von Ernährungsbotschaften in den Medien konfrontiert, sowohl anhand von klassischen Werbungen als auch in redaktionellen Kontexten. Da für Kinder das Fernsehen im Alltag das präsenteste Medium darstellt, ist das Wissen über die Wirkung von TV-Ernährungsbotschaften auf ihr Ernährungsverhalten besonders wichtig. Kommu...
Right-wing terrorism (RWT) poses an increasing threat to Western societies, with perpetrators targeting diverse members of society. We investigated the affective and attitudinal outcomes of exposure to news about RWT, depending on the victims’ religious affiliation (Christian vs. Muslim). Results of a quota-based experiment in [Austria; predominant...
The hostile media phenomenon (HMP) refers to a process in which supporters and opponents of an issue perceive the identical coverage to be biased against their own views. Despite the relevance of visual communication in our field, scholars have treated hostile media perceptions as a text-based phenomenon ignoring the unique role of visuals. This pa...
Negative campaigning is a central concept in political communication research. However, most conceptualizations of the term are rather broad, summarizing all kinds of negativity such as substantial criticism and offensive behaviors. In this paper, we distinguish negative, dirty, and positive campaigning. While negative campaigning refers to critica...
The transition from low- to high-choice media environments has had far-reaching implications for citizens’ media use and its relationship with political knowledge. However, there is still a lack of comparative research on how citizens combine the usage of different media and how that is related to political knowledge. To fill this void, we use a un...
We examined how Muslims are depicted in connection with Islamist terrorism and to what extent journalists use undifferentiated coverage – that actively links Muslims to terrorism – and differentiated coverage that actively differentiates Muslims from terrorism. Drawing from research in journalism studies and from terror management theory, we examin...
As a consequence of children’s nearly ubiquitous smartphone use, many parents experience resignation or frustration due to a perceived loss of control over their child’s excessive smartphone activities. This perceived lack of control may not only increase children’s risk of exposure to online harassment but also affect the relationship between pare...
In the context of exceeding levels of sugar consumption, some food companies advertise high-sugar products using inappropriate and misleading health claims (i.e. healthwashing). To reduce sugar consumption , consumers need to recognize what these healthwashed claims are. This study investigates how prior sugar-related health information moderates t...
Citizen science research has been rapidly expanding in the past years and has become a popular approach in youth education. We investigated key drivers of youth participation in a citizen social science school project and the effects of participation on scientific and topic-related (i.e., political) interest and efficacy. Findings suggest that fema...
We investigate the effects of populist messages that (a) stress the centrality of “ordinary” people, (b) shift blame to the “corrupt” elites, or (c) combine people centrality and antielitist cues on 3 dimensions of populist attitudes: anti-elitism, homogeneous people, and popular sovereignty. We conducted an extensive 15-country experiment in which...
Islamist terrorist attacks have become a salient threat to Western countries, and news coverage about such crimes is a key predictor of public emotional reactions and policy support. We examine the effects of two key characteristics of terrorism news coverage: (1) the victim’s religion and (2) first-person narratives that facilitate perspective tak...
BACKGROUND
Given that governmental prevention measures restricted most face-to-face communications, online self-disclosure via smartphones emerged as an alternative coping strategy that aimed at reducing the impact of the COVID-19 pandemic on people’s psychological health. Prepandemic research demonstrated that online self-disclosure benefits peopl...
Parental regulation of children's smartphone use is typically associated with conflict. To explain conflict, this paper focused on parents' own smartphone use. A panel survey among parent-child pairs (NTme2 = 384) revealed that parents' excessive smartphone use at Time 1 was associated with a lack of control over children's smartphone use at Time 2...
One of the most critical arenas for conflicts between parents and their children relates to food. Although parent-child conflicts about food are a real occurrence, this form of parent-child interaction has been rarely examined. Given the special role of parents in shaping children's diet, we especially focus on the impact of parental measures. This...
Public concern over misinformation has reached worrying levels in recent years. This phenomenon stimulates a climate of information uncertainty under which individuals may also question high-quality information that is needed to sustain meaningful political debates. To address this issue, this panel study investigates antecedents of perceived misin...
This study investigates antecedents and consequences of incidental and intentional exposure behavior to political information on social media. Based on the Social Media Political Participation Model (SMPPM), we investigated how political and non-political motivations predict intentional and incidental exposure modes while accounting for moderators...
Aim
The depiction of alcohol on television is an important explanatory variable for drinking behaviour. Even though alcohol consumption is frequently shown on popular TV shows, research on the impact of TV characters as models of drinking behaviour remains scarce. We theorise that the perceived similarity to a TV character is a key mechanism to exp...
The present study took an actor-based approach to explain news differentiation in terrorism coverage. Actors were defined as non-Muslim sources, Muslim sources, and journalists. Actors who generate undifferentiated statements actively link Muslims to terrorism, whereas actors who use differentiated statements explicitly distinguish Muslims from ter...
This study investigates whether the source providing nutritional information matters for children's choice of fruit over candy. We conducted a between-subject experimental study with children (6–11 years; Mage = 8.20; N = 340). Children watched an audiovisual cartoon with nutritional messages provided by experts (expert condition), by celebrities (...
Brand placements are a widely used advertising technique in entertainment media such as movies or TV shows. Yet, the presented brand placements do not always portray real brands. In media content like comedies, brand placements are occasionally spoof brands, which humorously mimic the real brand in their name and logo. Yet, how spoof brand placemen...
There is a lack of comparative research on nudity in television advertising. Building on cross-cultural theory, we examined countries’ gender indices and preclearance policies as predictors of nudity. We also tested the influence of a main actors’ gender and age, as well as the role of product categories. We sampled N = 1,755 TV ads from 13 countri...
According to the law of the European Union (EU), broadcasters are obligated to inform consumers about the presence of product placements (PP) through disclosures. To ascertain whether disclosures are able to improve consumers’ understanding of persuasive intent, researchers have examined the impact of multiple disclosure presentations. This can be...
