This experimental study examines potential effects of the experience of parasocial interaction (EPSI) on persuasion. We particularly look at a potentially moderating role of people's involvement.

College years are a peak period for the onset of many mental disorders, particularly mood, anxiety, and substance use disorders (De Girolamo, Dagani, Purcell, Cocchi, & McGorry, 2012). Understanding the current prevalence of mental health disorders among college students can contribute to the early identification and prompt management of mental health disorders in college students. Moreover, identification of prevalence estimates is essential to inform service planning, resource allocation, training, and research priorities (Costello, Burns, Angold,...

This study is developed aiming in extending the findings in our previous study of WTR, ME, and Aggression (registered as osf.io/qgzs8). By using different emotion measurements and a different design, we aim to replicate our previous finding and also for its further extension of generalization.

Theoretical background and hypotheses for a experimental vignette study on how perceptions of gossip affect reactions to gossip

36 items have been developed to construct the Hazardous Organization Preference Scale from a previous preregistered study (osf.io/js7vf). These items have been further validated in a working adult sample. Results indicated the unidimensional nature of the Hazardous Organization Preference Scale. HEXACO Honesty-Humility was found to be the strongest personality predictor. The purpose of the current study is two-fold: 1) to further establish the structure, psychometric properties, and select final scale items, 2) to further validate...

Intergroup biases are widespread across cultures and time. The current study tests an existing hypothesis of such biases: outgroups are viewed as pathogen threats. Multiple studies testing this hypothesis have revealed inconsistent results. Adapting methods from earlier work, the proposed study aims to test whether people are less comfortable with contact with an ethnic outgroup member than an ethnic ingroup member, and if this difference is exacerbated by additional visual cues to a target’s infectiousness....

Psychological treatment of depression with other comorbid mental disorders: Protocol for a systematic review and meta-analysis

Previous research has shown individuals are able to think about their interdependence within different situations (Gerpott, Balliet, Columbus, Molho & De Vries, 2016). However, the question remains if this ability pertains to everyday relationships, regardless of the situation people are in. Most authors researching interdependence in relationships oriented on measuring perceived closeness (Aron, Aron & Smollan, 1992; Berscheid, Snyder, and Omoto, 1989) and interdependency in teams, family, or peer relationships (Laursen & Williams, 1997). However,...

In Study 1, we did not describe the moral violation that the second- or third-party was responding to. Although this approach maximized the consistency between moral event contents the participants imagined and the emotion expression the agents expressed, it may have led participants to assume that anger versus disgust expressors had witnessed different moral violations. For example, participants might have been more likely to assume that disgust-expressors witnessed moral violations with some sexual or pathogen...

The aim of this project is to provide an overview of trial registration and selective outcome reporting in randomized controlled trials of psychological interventions for depression. We will examine the presence of selective outcome reporting in prospectively registered trials and its association with the published treatment effects.

Database for the OSIPI challenge on DCE-MRI (TF6.2)

Wood et al. (2012) found that belief in contradictory conspiracy theories are positively correlated. For instance, participants were asked to what degree they believed Princess Diana was murdered and, alternatively, faked her own death, and the results revealed a positive correlation. This correlation is commonly interpreted as evidence that those who believe in one conspiracy theory also are more likely to believe a contradictory conspiracy theory. Here we test an alternative explanation for this correlation:...

Individual participant data (IPD) meta-analysis on the intergenerational transmission of unresolved loss and abuse.

This scoping review aims to provide (1) an overview of different kinds of definitions of the notion of ‘fundamentalism,’ in relation to the notions of ‘terrorism,’ ‘radicalization,’ and ‘extremism;’ and (2) an overview of different kinds of definitions of the notion of ‘fundamentalist belief,’ as well as insights into its conceptual relations with the notions of ‘extremism/extreme belief’ ‘radicalism/radical belief’ and ‘terrorism/terrorist ideology.’ This review is part of the project EXTREME (Extreme Beliefs: The Epistemology...

Experimental lab study manipulating goals that can be attained through gossip

Experience Sampling Study on Gossip

Meta-analysis of psychotherapies usually report effects sizes. For patients and clinicians, however, it is important to know what the chances are of getting better after a treatment. The SMD is not very informative in this respect and cannot be see as an indicator of clinical relevance, because it is still a statistical concept. For patients and clinicians it is important to simply now the proportions of patients who get better when they receive treatment and...

Background. The number of trials on psychotherapies for adult depression is very large and is quickly growing. Because of this large body of knowledge, it is important that the results of these studies are summarized and integrated in meta-analytic studies. More than a decade ago we developed a meta-analytic database of these trials, which was updated yearly through systematic literature searches. Recently, we developed a new version of this meta-analytic database, built on the systems...

Psychological problems are prevalent among college students (Auerbach et al., 2016, 2018; Mortier et al., 2018). The onset of the common psychological disorders peaks during college years (Kessler et al., 2007). At this developmental stage, college students encounter several stressors including academic demands, changes in relationships and lifestyle, and financial problems (Acharya, Jin, & Collins, 2018). As a result, a considerable number of college students experience elevated levels of stress. However access to mental health...

This research is the first study into the validation of the questionnaire instrument for evaluating human interaction with an artificial social agent. It involves crowd workers on an online crowdsourcing platform. They will be asked to use the questionnaire instrument to rate an interaction between an agent and a human user, which is displayed in a 30 second video clip. The result of this study will be analysed and used to examine the reliability of...
