Recent Decreases in Specific Interpretation Biases Predict Decreases in Neuroticism: Evidence From a Longitudinal Study With Young Adult Couples

Engaging in a romantic relationship represents one important life experience in young adulthood that has been shown to catalyze age‐related decrease in neuroticism (Neyer & Lehnart, 2007). The current research builds directly on this finding by investigating one process that underlies the partnership effect. We focused on the relationship‐specific interpretation bias (RIB; Finn, Mitte, & Neyer, 2013), which is the tendency to interpret ambiguous partner and relationship scenarios in a negative way. It was expected that the RIB decreases within relationships in young adulthood and that this decrease in turn predicts long‐term declines in neuroticism. A sample of 245 young adult romantic couples was assessed four times across 9 months. Actor and partner effects of changes in the RIB on changes in neuroticism were analyzed using a dyadic dual change model. Recent time‐to‐time decreases in the RIB predicted one's own (actor effect) decline in neuroticism across 9 months. Similarly, there was a trend for a partner effect. We conclude that changes in biased relationship‐specific interpretations reflect one unique process that contributes to the understanding of romantic relationship effects on personality development.     

From STEM to STEAM: How to Monitor Creativity

Creativity is a broad and complex construct, difficult to define and to quantify, assumed to introduce new impulses into science education (STEM), and leading to better acceptance of science by adolescents. Therefore, increasing efforts are being undertaken to integrate traditional creativity (Arts), in modifying STEM to STEAM. Consequently, a valid way of empirically quantifying of creativity of adolescents is needed. In this study, part of a European initiative (CREATIONS), an 8-item Likert-scale questionnaire quantifying individual creativity was administered to a sample of 2,713 students, aged 11–19 (M ± SD = 15.71 ± 2.24; 54.7% females), revealing two subscales: one, labelled Act, covering conscious and trainable cognitive processes; the second, named Flow, contained items describing elements of flow experiences, a mental state of creativity. Analyses indicated that there were no gender differences and that younger students’ creativity scores were higher than those of older students. Recommendations for implementation in STEAM lessons are discussed.

Social competence of adult chimpanzees (Pan troglodytes) with severe deprivation history: I. An individual approach

Early social deprivation in highly social mammals interferes with their varying needs for security and stimulation. Toleration of social stimulation was studied in 18 adult ex-laboratory chimpanzees, who had been deprived for 16 to 27 years, during their 1st year after resocialization into 1 of 3 social groups. For this, a model of social competence was developed with 5 grades of social stimulation. The chimpanzees were classified as either early deprived (EDs; M = 1.2 years) or late deprived (LDs; M = 3.6 years) according to their age at entering the laboratory. EDs did not differ significantly from LD chimpanzees in the first 3 grades of social stimulation (i.e., the toleration of stationary vicinity, initiation of brief sociopositive contacts and gentle social play). LDs, however, clearly exceeded EDs in the 4th and 5th grade of social stimulation (i.e., their engagement in allogrooming and their toleration of passive close proximity). Furthermore, LDs showed greater social initiative in changing a social situation and had more expanded grooming networks compared with EDs. Moreover, in LDs and ED females, but not in ED males, toleration of stationary vicinity increased from the 1st to the 2nd year of group living.     

Religion and Esotericism among Students: A Cross-Cultural Comparative Study

Analysing the results of a study on religious and esoteric beliefs and practice among university students from five European and five American countries, we found that the level of religiousness of students depends very much on their cultural environment: the level of religiosity and esoteric beliefs is significantly higher among North- and South-American students than among European students. On the other hand, Asian spiritual techniques and esoteric methods of healing are practised more frequently by students in North-Western European countries. In the second part of the paper, we examine the relationship between academic discipline and religious worldviews. According to our data, students in the social sciences and the arts are more distanced from religion than students of other areas of science, but they, like students of medicine and languages, are closer to esotericism than students of the 'exact sciences'. Several hypotheses are proposed to explain these results.     

A Theory of Bayesian Groups

A group is often construed as one agent with its own probabilistic beliefs (credences), which are obtained by aggregating those of the individuals, for instance through averaging. In their celebrated “Groupthink”, Russell et al. (2015) require group credences to undergo Bayesian revision whenever new information is learnt, i.e., whenever individual credences undergo Bayesian revision based on this information. To obtain a fully Bayesian group, one should often extend this requirement to non‐public or even private information (learnt by not all or just one individual), or to non‐representable information (not representable by any event in the domain where credences are held). I propose a taxonomy of six types of ‘group Bayesianism’. They differ in the information for which Bayesian revision of group credences is required: public representable information, private representable information, public non‐representable information, etc. Six corresponding theorems establish how individual credences must (not) be aggregated to ensure group Bayesianism of any type, respectively. Aggregating through standard averaging is never permitted; instead, different forms of geometric averaging must be used. One theorem—that for public representable information—is essentially Russell et al.'s central result (with minor corrections). Another theorem—that for public non‐representable information—fills a gap in the theory of externally Bayesian opinion pooling.
