Article
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...

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...
Article
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...

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...
Article
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...
Article
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...

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...
Chapter
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...

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...

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...
Article
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...

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...

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...

Article
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...
Article
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...

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...
Article
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...
Article
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...

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...

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...

Research on persuasive cues of food placements in entertainment media targeted at children is still scarce. We investigated whether healthy food placements (i.e., fruit) connected to different persuasive cues (i.e., cognitive, affective, and combined) can enhance children’s (age 6-11 years old) healthy food choice. A pretest (N = 154) confirmed tha...
