The ability to inhibit impulses is related to social behavior in long-tailed macaques.

Performance in cognitive tasks has been linked to differences in species' social organization, yet to understand its function its relationship to within-species variation in behavior should also be explored. One important cognitive capacity, the ability to inhibit impulses, is typically better in egalitarian than despotic primate species and in primate species with strong fission-fusion dynamics. A different line of research indicates that a high ability to inhibit impulses is related to less aggressive behavior and more socio-positive behavior.

Food sharing with friends and acquaintances: A study in preschool boys and girls.

Introduction: The current study examined whether preschoolers in a (semi-)natural situation shared more food with friends or acquaintances, and whether this was different between boys and girls, older and younger children, and for preferred and non- preferred food. In order to do so, we replicated and extended the classical work of Birch and Billman in a Dutch sample.

Methods: Participants included 91 children aged between 3 to 6 years (52.

How to Get the Biggest Slice of the Cake. A Comparative View of Social Behaviour and Resource Access in Human Children and Nonhuman Primates.

Social complexity results from engaging in different classes of social behaviour. The presence of different classes of social behaviour is reflected in multidimensional concepts of social asymmetry, found in both human and nonhuman primates. Based on an overview of such concepts, we propose that three classes of social behaviour are involved in having access to scarce and desired resources: next to aggressive and affiliative behaviour, also action indicating behaviour (i.

Classroom Size and the Prevalence of Bullying and Victimization: Testing Three Explanations for the Negative Association.

Classroom size - i.e., the number of students in the class - is a feature of the classroom environment often found to be negatively related to bullying or victimization.

Longitudinal Associations Between Adolescents' Bullying-Related Indirect Defending, Outsider Behavior, and Peer-Group Status.

During adolescence, youth become more likely to avoid involvement in witnessed bullying and less likely to support victims. It is unknown whether-and how-these bystander behaviors (i.e.

Is Inspiring Group Members an Effective Predictor of Social Dominance in Early Adolescence? Direct and Moderated Effects of Behavioral Strategies, Social Skills, and Gender on Resource Control and Popularity.

Dominance in the peer group is important for adolescents. Resource Control Theory posits that both coercive and prosocial (positively assertive) strategies are associated with dominance. Combining Resource Control Theory with Socioanalytic Theory on personality, we hypothesized that inspiring group members would be an additional effective strategy.

Peer and self-reports of victimization and bullying: their differential association with internalizing problems and social adjustment.

Researchers typically employ either peer or self-reports to assess involvement in bullying. In this study, we examined the merits of each method for the identification of child characteristics related to victimization and bullying others. Accordingly, we investigated the difference between these two methods with regard to their relationship with social adjustment (i.

Bullying as strategic behavior: relations with desired and acquired dominance in the peer group.

To examine whether bullying is strategic behavior aimed at obtaining or maintaining social dominance, 1129 9- to 12-year-old Dutch children were classified in terms of their role in bullying and in terms of their use of dominance oriented coercive and prosocial social strategies. Multi-informant measures of participants' acquired and desired social dominance were also included. Unlike non-bullying children, children contributing to bullying often were bistrategics in that they used both coercive and prosocial strategies and they also were socially dominant.
