Cognition plays a key role in sports performance. This meta-analytic review synthesizes research that examined the relationship between cognitive functions, skills, and sports performance. We identified literature by searching Cochrane Library, APA PsycINFO, PubMed, and Web of Science. We included studies conducted on competitive athletes, assessed cognitive prerequisites, and included performance measures related to the sport. Of the 9,433 screened records, 136 reports were included, containing 142 studies, 1,227 effect sizes, and 8,860 participants. Only 11 studies used a prospective study design. The risk of bias was assessed using the Risk of Bias Assessment Tool for Nonrandomized Studies. The multilevel meta-analysis showed a medium effect size for the overall difference in cognitive functions and skills, with higher skilled athletes scoring better than lower skilled athletes (Hedges’ g = 0.59, 95% CI [0.49, 0.69]). The moderator analysis showed larger effect size for tests of cognitive decision-making skills (g = 0.77, 95% CI [0.6, 0.94]) compared to basic (g = 0.39, 95% CI [0.21, 0.56]) and higher cognitive functions (g = 0.44, 95% CI [0.26, 0.62]), as well as larger effect for sport-specific task stimuli compared to general ones. We report that higher skilled athletes perform better on cognitive function tests than lower skilled athletes. There was insufficient evidence to determine whether cognitive functions and skills can predict future sport performance. We found no evidence to support claims that tests of general cognitive functions, such as executive functioning, should be used by practitioners for talent identification or player selection.

Research has shown that vicarious contact, that is observing an interaction between ingroup and outgroup members, can improve intergroup relations. Although vicarious contact has been operationalized in different ways, mainly via story reading or video watching, an experimental comparison of these different strategies is still missing. We conducted a school intervention with the aim of comparing the two most used forms of vicarious contact, namely story reading and video watching. Elementary schoolchildren without disabilities (N = 292) were assigned to one of three different conditions: reading a story; watching a video; control. In the two vicarious contact conditions, participants read or watched the story of a child with disability becoming friends with children without disabilities; in the control condition, participants only completed the dependent measures. Results revealed that, in general, both vicarious contact conditions were equally effective in improving outgroup attitudes and behavioural intentions. In addition, they operated with the same strength through the same underlying processes (IOS, ingroup norms). We discuss theoretical and practical implications in the context of vicarious contact as a prejudice-reduction intervention. Despite that research on intergroup contact has shown that direct, face-to-face contact between groups can reduce prejudice (Hodson & Hewstone, 2013; Pettigrew & Tropp, 2006), the implementation of direct contact is often impractical. Research has, however, demonstrated that indirect contact, that is contact that is not face to face, can also help improve intergroup relations. Among the different forms of indirect contact strategies that can improve attitudes, in this research we focus on vicarious contact, that is the observation of interactions between ingroup and outgroup members. This form of contact is distinct from extended contact, that is knowing about positive intergroup interactions

Trauma‐informed care is emerging as a promising good practice to recognise, treat and prevent trauma in young children. The use of trauma‐informed care in childcare organisations might have a positive impact on children who suffer from child maltreatment. The current study organised desk research and focus group discussions with professional experts in Latvia, Italy, Hungary and Belgium to assess if trauma‐informed care is known, applied or taught. The joint conclusions of the desk research and the focus group discussions demonstrated that childcare professionals currently lack the knowledge, skills and attitude to engage in trauma‐informed care. Even though they have ways to prevent and tackle trauma, these ways are often based on gut feeling or experience and are not formalised or explicitly addressed. This lack of conscious knowhow is an issue that possibly leads to underreporting of situations of child maltreatment and a lack of attuned responses to children suffering from child maltreatment. Overall, there were no training initiatives focused on trauma‐informed care for childcare professionals, which might explain why these good practices do not reach the sector.

We conducted an experimental intervention to test the effectiveness of vicarious contact in the relationship between Turkish and Syrian elementary school children; the participants were Turkish children. We used a mixedmethods approach, investigating effects by using both quantitative and qualitative methodologies. Participants in the experimental condition were asked to read stories on positive contact between Turkish and Syrian children over the course of six weekly sessions. The results revealed that vicarious contact, compared to a control condition where participants did not engage in any activity, led to greater intentions to help outgroup members. Importantly, effects only emerged among children who reported higher initial negative outgroup attitudes. Results from qualitative data revealed that vicarious contact produced richer, more positive, and complex representations of the relationships and friendships between groups. We discuss the theoretical and practical implications of these findings.
