Registered Replication Report: Dijksterhuis and van Knippenberg (1998)

Dijksterhuis and van Knippenberg (1998) reported that participants primed with a category associated with intelligence ("professor") subsequently performed 13% better on a trivia test than participants primed with a category associated with a lack of intelligence ("soccer hooligans"). In two unpublished replications of this study designed to verify the appropriate testing procedures, Dijksterhuis, van Knippenberg, and Holland observed a smaller difference between conditions (2%-3%) as well as a gender difference: Men showed the effect (9.3% and 7.6%), but women did not (0.3% and -0.3%). The procedure used in those replications served as the basis for this multilab Registered Replication Report. A total of 40 laboratories collected data for this project, and 23 of these laboratories met all inclusion criteria. Here we report the meta-analytic results for those 23 direct replications (total N = 4,493), which tested whether performance on a 30-item general-knowledge trivia task differed between these two priming conditions (results of supplementary analyses of the data from all 40 labs, N = 6,454, are also reported). We observed no overall difference in trivia performance between participants primed with the "professor" category and those primed with the "hooligan" category (0.14%) and no moderation by gender

I'll never forgive you: High conflict divorce, social network, and co-parenting conflicts

Contains fulltext : 177372.pdf (Publisher’s version ) (Open Access)The relation between divorce, co-parenting conflicts, and children's adjustment problems has been well established. An unresolved question for research and clinical interventions, however, is how conflicts between parents are maintained and/or escalate. This cross-sectional research tested the hypothesis that co-parenting conflicts in divorced couples are associated with perceived social network disapproval and that this relation is mediated by parents' tendency to forgive each other. In Study 1, a convenience sample of 136 divorced parents recruited via online forums, we showed that perceived social network disapproval was indeed positively related to co-parenting conflicts and that parents'tendency to forgive the other parent - albeit partly - explained this relationship. Strength of 0our research is that in Study 2, 110 parents referred to children's mental health care because the wellbeing of the children was severely compromised by the severity of the conflicts between parents, we replicated these results. In both studies perceived social network disapproval and co-parenting conflicts were positively related and this link was mediated by forgiveness: perceived social network disapproval was negatively related to forgiveness, which in turn was negatively related to more parental conflicts.12 p
