Studies have shown positive associations between liking a Facebook brand page and brand evaluations, but causal evidence is lacking. This online pre- post-measure experiment compared brand evaluations of ‘current followers’ of a target brand’s Facebook page, with ‘new followers’ instructed to ‘like’ the page, and ‘non followers’ over one month. Res...

In this paper, we investigate whether and to what extent exposure to a company's social media activities over time is beneficial for corporate reputation, and whether conversational human voice mediates this relation. In a two-wave longitudinal survey among 1969 respondents, we assessed consumers' exposure to an international airline's social media...

Social networking sites (SNS) play an increasingly important role in maintaining geographically close romantic relationships (GCRR). However, knowledge about SNS use in long-distance romantic relationships (LDRR) is still lacking. The present study examined the relative importance of SNS in maintaining LDRR compared to GCRR, particularly with regar...

Health-related misinformation, especially in times of a global health crisis, can have severe negative consequences on public health. In the current studies, we investigated the persuasive impact of COVID-19-related misinformation, and whether the valence of the misinformation and recipients' degree of overconfidence affect this impact. In two pre-...

A lack of cross-cultural research has been identified regarding cultural tourism promotion on social media. Using the dimensions of Collectivism-Individualism, Power Distance, and High-Context vs. Low-Context communication, we content analyze cultural value differences in Instagram posts promoting cultural tourism – published by the national touris...

This research examines the effects of localizing cultural values on perceived image and willingness to visit a heritage site. Using Collectivism-Individualism and Power Distance, two preregistered experiments were conducted with a total of 2039 respondents from Portugal and United Kingdom. In Study 1, against expectations, culturally incongruent we...

The impetus for this study is the proposition that social network sites (SNSs), like Facebook, can be beneficial for romantic relationships via network support functions. This study investigated a model which proposes that the use of Facebook predicts relationship support from Facebook connections, and this, in turn, predicts relationship stability...

Homesickness is one of the challenges that international students may encounter when they leave home. Homesickness is associated with social interactions and sociocultural adjustment, yet the directions of associations and temporal precedence are not clear. Thus, in this study, we tested a model which proposes that face-to-face (FtF) interaction wi...

Consumers have made abundant use of social media to share their experiences with and evaluations of products, services, and policies—and with the organizations that produce them. Consumer voices, or electronic word-of-mouth (eWOM), can be heard on social network sites, online review sites, the comments section of news sites, and, in general, in all...
Article
Why is it difficult to resist social media temptations? One reason might be that social media users have strong and spontaneous approach reactions to social media cues. In the present study, daily Facebook users (N = 228) completed a Stimulus-Response Compatibility (SRC) task, which assessed their spontaneous approach reactions to Facebook cues. Re...

Social media users often experience the difficulty of controlling their social media use while having important tasks to do. Recent theorizing on self-control and media use proposes four possible factors (immediate gratifications, habitual checking, ubiquity, and notifications) that might cause social media self-control failure (SMSCF). We tested w...
Article
Self-disclosure happens between people and lies at the heart of almost all relationships. It elicits a dynamic process that shapes and is shaped by, relationships. We review theoretical and empirical milestones in our understanding of how and why disclosure develops, is maintained, and unravels in relationships. We show that people use their and th...

We investigated the proposition that among international students, face-to-face (FtF) interaction with the host-country network, and Facebook interaction with the host-and the home-country networks predict perceived social support, which, in turn, predicts psychological adjustment. We tested the model using cross-lagged and non-lagged reciprocal ef...

In this paper, we analyze the content of the most popular videos posted on YouTube in the first phase of the Zika-virus outbreak in 2016, and the user responses to those videos. More specifically, we examine the extent to which informational and conspiracy theory videos differ in terms of user activity (number of comments, shares, likes and dislike...
Article
People often fail in controlling their social media use when it conflicts with other goals and obligations. To facilitate research on understanding social media self-control failures, we constructed a brief social media self-control failure (SMSCF)-scale to assess how often social media users give in to social media temptations. Social media users...

Background: A lack of physical activity is considered to cause 6% of deaths globally. Feedback from wearables such as activity trackers has the potential to encourage daily physical activity. To date, little research is available on the natural development of adherence to activity trackers or on potential factors that predict which users manage to...

PowerPoint presentations are often criticized for the excessive use of text on the slides. In a study of 97 academic scholars, we found that presenters indeed used substantially more text than is advised. Speaking anxiety was found to be related to the time spent on preparing and rehearsing, and time spent on rehearsing is related to the number of...

This study aims to shed more light on the question whether, and under what circumstances, valence affects consumers’ intention to buy a product after reading an online review. We hypothesize that receiver expertise could possibly moderate (a) the impact of review valence on consumers’ purchase intentions, and (b) the asymmetric effects of positive...

PowerPoint has received much criticism regarding excessive use of text and the lack of contact with the audience. Why presenters use PowerPoint in this way has not been studied so far. Our study using interviews with beginning and advanced presenters shows that some use the program as a speaking note and as a means to draw the attention away from t...

When consumers are dissatisfied with a consumption experience, they usually respond in one of the following ways (Hirschman, 1970): (1) stop using an organization’s products/services and take their business to a competitor, (2) file a complaint with the organization that is responsible for the dissatisfying consumption experience, or (3) talk about...

Previous studies have shown that social media use among participants in the 25 January Egyptian uprising was high and that protesters indicate that social media were important in their decision to join the protests (Tufekci & Wilson, 2012; Wilson & Dunn, 2011). However, other studies suggest that the attitudes toward the regime and toward democracy...

To be a trustworthy partner, people need self-control. People infer others’ level of self-control from behavioral cues, and this perception influences how much they trust others. Exhibiting compulsive Internet use (CIU) might provide such cues. This research examined whether and how CIU affects perceptions of self-control and trust in a partner. In...

In this paper we compare the effects of different organizational crisis responses in social media after negative publicity regarding the organization. Building on earlier work in crisis communication (e.g., Bradford & Garrett, 1995; Kim, Avery & Lariscy, 2009), we distinguish apology and denial as organizational responses. Building on recent work o...

This article examines how compulsive Internet use and marital well-being are related to each other. We suggest that they are negatively related and explore whether compulsive Internet use predicts marital well-being or vice versa. The relation between compulsive Internet use and marital well-being is tested in a two-wave prospective study among 190...

Two studies examined the impact of online store reviews on consumer trust in online stores. Based on the warranting principle, it was proposed that consumer reviews are a more important cue for judging the trustworthiness of an online store than the overall reputation of the store (Experiment 1) or assurance seals (Experiment 2). The role of dispos...

Buying online is still perceived as risky. A key strategy of online marketers to increase consumer trust in online ordering is to display privacy and security seals on their web sites. Although research indicates that these Internet seals do not necessarily mean better safety for online consumers, findings of several other studies demonstrated that...

This article examines how perceiving concealment in close relationships influences marital well-being. It suggests that the perception of concealment from a partner signals separateness from one's partner and contributes to feelings of perceived partner exclusion. These feelings of exclusion, in turn, should negatively affect relational quality. Th...

Three studies tested predictions derived from terror management theory (TMT) about the effects of terrorism news on prejudice. Exposure to terrorism news should confront receivers with thoughts about their own death, which, in turn, should increase prejudice toward outgroup members. Non-Muslim (Studies 1–3) and Muslim (Study 3) participants were ex...

Safety cues are frequently used in online stores to relieve consumers’ risk perceptions concerning online purchases. This paper uses regulatory focus theory (RFT) to predict the persuasiveness of online safety cues. According to RFT (Higgins, 1997), people process information differently depending on whether they strive for achieving gains (promoti...

This experimental study assessed the effectiveness of fundraising messages. Based on recent findings regarding the effects of message framing and evidence, effective fundraising messages should combine abstract, statistical information with a negative message frame and anecdotal evidence with a positive message frame. In addition, building on resea...

In two experiments, the impact of shopping context on consumers' risk perceptions and regulatory focus was examined. We predicted that individuals perceive an online (vs. conventional) shopping environment as more risky and that an online shopping environment, by its risky nature, primes a prevention focus. The findings in Study 1 demonstrate these...

IT TAKES a constant stream of interpersonal decision making for people to be liked by others and to like themselves at the same time. Although often being liked and liking oneself go hand in hand, at times people make choices to give up on being liked in order to restore a positive self-image or to temporarily have a less positive self-image to pre...

Two survey studies were conducted to test whether the adoption of e-services offered to customers can be better explained by either trust or commitment. Several studies have already established the effect of trust on adopting e-services. Based on studies in the literature on trust and commitment in intimate relationships, as well as studies on the...

Although concealment in relationships is commonplace, little is known about its implications for the target of concealment. Two large-scale studies among adolescents and their parents tested the central hypothesis that parents’ perception of child concealment predicts poorer parenting behaviors toward their child. Further, we investigated whether a...

In Western Europe, works councils are a common form of indirect employee participation in management decision making. Trust is often assumed to play an important role in the nature and outcomes of labour negotiations and in management-works council consultations. So far, however, the antecedents of trust in management within works councils have not...
