Describing people we like and people we dislike in terms of HEXACO personality

Patrick Dunlop, Reinout de Vries & Anupama Bharadwaj
In this study, participants were asked to describe using written text, a person they liked and a person they disliked. Participants also completed a self-report HEXACO100 questionnaire, excluding the altruism items. The written descriptions were coded by three judges, who were asked to identify descriptions that included high levels or low levels of each of the six HEXACO personality dimensions. Judges also identified any descriptions that were particularly vitriolic. All judges were trained in a...

A Systematic Review of Predictors and Moderators of treatment outcome and symptom deterioration in internet- and mobile-based interventions for depression

Theresa Sextl, Anna-Carlotta Zarski, Maria Steinhoff, Harald Baumeister, Pim Cuijpers & David Ebert
Depression is a highly prevalent mental disorder and is associated with substantial impairment and reduced quality of life for affected individuals. Internet- and mobile-based interventions (IMIs) have shown to be a promising, cost-effective, and for therapists and patients acceptable way to treat this disorder. Their efficacy is well documented, so that IMIs have proven to be as effective as face-to-face therapy. However, not all patients treated with IMIs benefit to the same extent. Not only...

Relationship Interdependence Scale: Validity testing

Tiffany Matej Hrkalovic, Daniel Balliet & Francesca Righetti
The following study presents a continuation in the development of the multidimensional relationship interdependence scale. As a response to the first study, which was oriented on item reduction and testing the hypothesized seven-factor model of interdependence, as well as measurement invariance, this study will be oriented on testing the fit of an adjusted five-factor model of relationship interdependence with a reduced item pool. Additionally, the second aim of the study will be to test the...

Study 7: Confirmatory Factor Analysis

Siska Fitrianie, Willem-Paul Brinkman, Merijn Bruijnes, Kim Baraka, Rianne van den Berghe, Ulysses Bernardet, Tibor Bosse, Frances Brazier, Jacob Browne, Franziska Burger, Mathieu Chollet, Leigh Clark, Benjamin Cowan, Salam Daher, Ding Ding, Frank Foerster, Emer Gilmartin, Catholijn Jonker, Mirjam de Haas, Mojgan Hashemian, Evelien Heyselaar, Kangsoo Kim, Marion Koelle, Barbara Kuhnert, Felix Lindner … & Katja Zibrek
This research is the second 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 associations of...

Testing the effect of headline formulations on news selection

Nicolas Mattis, Wouter van Atteveldt & Luuk Lagerwerf
News selections in recommender systems are complex, multi-faceted processes that can be affected by a range of stable and situational factors. In this process, the presentation of individual news articles matters. This includes their position in a list of individual news headlines as well as the way they are formulated. Prior research into news selection recommender systems indicates that the positioning of an article has important implications for how likely an article is to be...

Experience of Parasocial Interaction, Persuasion, and Involvement

Tilo Hartmann, Jayson Dibble & Sarah Rosaen
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.

Prevalence of Mental Disorders in College Students: A Systematic Review and Meta-analysis

Ruiying Zhao, Yagmur Amanvermez, Ronald Kessler & Pim Cuijpers
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,...

WTR, Moral Emotions, and Aggression In TPP (S2)

Lei Fan & Joshua Tybur
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.

Eco-evolutionary outsiders: establishing in a distantly related neighbourhood delays and reorganizes nutrient recycling

Xu Pan, Mathieu Santonja, Pierre-Emmanuel Courty, Olaf Butenschön, Matty Berg, Phil Murray, Benjamin Yguel, Daphnée Brulé & Andreas Prinzing
Rapid environmental change forces long-lived plants like trees to immigrate into zones still occupied by phylogenetically distantly related species. Does such phylogenetic isolation (PI) change the trees’ ecosystem functioning such as litter decomposition? We studied oaks (Quercus petraea) of low and high PI, reciprocally transplanting their litters to identify effect of aboveground litter quality and belowground decomposer biota. Across 8 and 14 months we quantified decomposition (mass loss, C-loss and N-loss), decomposer biota (Acari, Collembola,...

Social dysfunction is transdiagnostically associated with default mode network dysconnectivity in schizophrenia and Alzheimer’s disease

Ilja M. J. Saris, Moji Aghajani, Lianne M. Reus, Pieter-Jelle Visser, Yolande Pijnenburg, Nic J. A. van der Wee, Amy C. Bilderbeck, Andreea Raslescu, Asad Malik, Maarten Mennes, Sanne Koops, Celso Arrango, Jose Luis Ayuso-Mateos, Gerard R. Dawson, Hugh Marston, Martien J. Kas & Brenda W. J. H. Penninx
Social dysfunction is one of the most common signs of major neuropsychiatric disorders. The Default Mode Network (DMN) is crucially implicated in both psychopathology and social dysfunction, although the transdiagnostic properties of social dysfunction remains unknown. As part of the pan-European PRISM (Psychiatric Ratings using Intermediate Stratified Markers) project, we explored cross-disorder impact of social dysfunction on DMN connectivity. We studied DMN intrinsic functional connectivity in relation to social dysfunction by applying Independent Component Analysis...

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

HEXACO Honesty-Humility and Hazardous Organization Preference Scale (student sample)

B. Wang, Reinout de Vries & Wendy Andrews
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...

Group Membership & Contact Comfort

Lei Fan, Joshua Tybur & Benedict Jones
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

Relationship Interdependence Scale

Tiffany Matej Hrkalovic, Daniel Balliet & Francesca Righetti
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,...

Moral Emotion Perception - S2

Lei Fan, Joshua Tybur, Catherine Molho & Tom Kupfer
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...

A deep dive into fat: Investigating blubber lipidomics fingerprint of killer whales and humpback whales in northern Norway

Pierre Bories, Audun Rikardsen, Pim Leonards, Aaron Fisk, Sabrina Tartu, Emma Vogel, Jenny Bytingsvik & Pierre Blevin
In cetaceans, blubber is the primary and largest lipid body reservoir. Our current understanding about lipid stores and uses in cetaceans is still limited and most studies only focused on a single narrow snapshot of the lipidome. We documented an extended lipidomics fingerprint in two cetacean species present in northern Norway during wintertime. We were able to detect 817 molecular lipid species in blubber of killer whales (Orcinus orca) and humpback whales (Megaptera novaeangliae). The...

Selective outcome reporting in randomized trials of psychological interventions for depression

Clara Miguel, Ioana Cristea, Eirini Karyotaki & Pim Cuijpers
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.

Belief in contradictory conspiracy theories

Jan-Willem van Prooijen, Nicole Mulas, Laura Mausolf, Shayda Shwan & Iris Guhring
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:...

Lack of lipid accumulation in two species of Chalcidoid wasps with secondarily evolved phytophagy

Jacintha Ellers
Stable co-evolutionary relationships between species can result in the loss of autonomous synthesis of essential nutrients when these can be obtained from the ecological partner. Parasitoid insects obtain the majority of their nutrients from their host, and contain multiple, independently-evolved lineages that do not increase their adult lipid reserves despite feeding on a surplus of dietary sugars, although some parasitoid species in these lineages were found to have reactivated adult lipogenesis. Several clades within the...

Item-validity analysis of the SED-S in a multicenter sample of adults with an intellectual disability

Hauke Hermann, Gloria Kempelmann, Brian Barrett, Sandra Zaal, Jolnada Vonk, Filip Morisse, Paula Sterkenburg & Tanja Sappok
Recognition of the level of emotional development (ED) is essential in adults with an intellectual disability to align treatment and support accordingly. The empirical-based Scale of Emotional Development – Short (SED-S) assesses the level of ED in 5 reference age groups from 0 - 12 years in eight different domains. The scale is assessed by an expert in developmental psychology in a semistructured interview with close caregivers. It consists of eight domains: ‘Relating to his/her...
