How does persuasion knowledge differ between humanlike virtual influencers and human influencers
Humanlike virtual influencers (HVIs) mimic human influencers (HIs), but how do consumers perceive them, and how does this affect persuasion knowledge? This experiment examines how consumers differentiate HVIs from HIs based on two mental states – intentions and emotions– and how differences in mind perception affect two dimensions of persuasion knowledge. Results reveal: (1) a negative indirect effect, where consumers attribute less intentions to…
Decoding AI ethics: What do ethical tools tell us about ethics
This study performs a systematic content analysis to map out the landscape of eighty-seven ethical tools concerning the type of ethical principles addressed, the approach promoted (technological vs. socio-technical vs. societal), and the kind of assessment endorsed (self-assessment versus assessment by others). The findings reveal a skewed representation and emphasis of specific ethical principles across these tools. Furthermore, ethical tools pr…
Exploring the dimensionality of Fear of Missing Out: Associations with related constructs
A growing body of research has examined the potential effects of the Fear of Missing Out (FoMO) whereby the Fear of Missing Out Scale (FoMOs; Przybylski et al., 2013) has become the most popular measure for assessing the construct. However, there is ambiguity regarding FoMO’s conceptualization and dimensionality. Employing a large representative sample (N = 2,041), this study provides direct empirical support for the conceptualization of FoMO as …
Fear of missing out and social media use: A three-wave longitudinal study on the interplay with psychological need satisfaction and psychological well-being
This three-wave longitudinal study ( n = 1341) examined between- and within-person effects linking fear of missing out (FoMO) and social media use to psychological need satisfaction and well-being over time. As such, this study tests the premise that FoMO can be understood as a self-regulatory limbo, arising from deficits in psychological need satisfaction and/or lower well-being. This limbo is suggested to lead to reciprocal relations between th…
Topical Advertising in enduring events: The role of timing and creativity in engagement with social media brand messages during Covid-19
Research has showed that aligning brand messages with topical events is a success formula for evoking positive consumer responses, in which ad creativity (i.e., originality, meaningfulness, and craftsmanship) and timing (i.e., the time between the start of an event and the appearance of a Topical Advertising message) play a pivotal role. This was demonstrated in the context of short, ending topical events. Less is known about the effects of align…

The Good, the Bad, and the Expert: How Consumer Expertise Affects Review Valence Effects on Purchase Intentions in Online Product Reviews
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 and negative reviews. To test these hypotheses, we conducted an experiment, exposing participants (n…
The Ironic Effect of Source Identification on the Perceived Credibility of Online Product Reviewers: The Ironic Effect of Source Identification
This study posits that sources of online product reviews can induce differential effects on 2 dimensions of source credibility, perceived expertise and perceived trustworthiness. Study 1 shows that experts are perceived as having more expert knowledge, but at the same time as having less trustworthiness than laypersons, and vice versa. These opposing credibility evaluations suppress the effect of online source identification on readers' attitudes…
Highly Recommended!” The Content Characteristics and Perceived Usefulness of Online Consumer Reviews
The aim of the present study was to gain a better understanding of the content characteristics that make online consumer reviews a useful source of consumer information. To this end, we content analyzed reviews of experience and search products posted on Amazon.com (N = 400). The insights derived from this content analysis were linked with the proportion of ‘useful’ votes that reviews received from fellow consumers. The results show that content …
Boundaries to the Articulation of Possible Selves Through Social Networking Sites: The Case of Facebook Profilers' Social Connectedness
This study aims to contribute to an emerging literature that seeks to understand how identity markers on social networking sites (SNSs) shape interpersonal impressions, and particularly the boundaries that SNSs present for articulating unconstrained "hoped-for possible selves." An experiment employing mock-up Facebook profiles was conducted, showing that appearing with friends on a Facebook profile picture as well as increasingly higher number of…
