Our prior research has suggested a connection between progesterone (PROG) and implicit affiliation motivation, the non-conscious drive for positive social contact. In particular, experimental arousal of affiliation motivation led to relative PROG increase in women and men [Schultheiss, O.C., Wirth, M.M., Stanton, S.J., 2004. Effects of affiliation and power motivation arousal on salivary proges...

The present study examined the interpersonal lives of individuals with social anxiety disorder (SAD). According to evolutionary and interpersonal theories, we construed the interpersonal world using the social rank and the affiliation psychological systems. Two studies assessed measures of social rank, affiliation, social anxiety and depression among a population of treatment-seeking individual...

The purpose of this study was to examine task-, ego-, and social-goal orientations as predictors of prosocial and antisocial behavior in youth soccer. Participants were 365 male (n = 227) and female (n = 138) youth soccer players (M age = 13.4 years, SD = 1.8), who completed questionnaires measuring task and ego orientation; the goals of social affiliation, social recognition and social status;...

Ovarian steroids and oxytocin (OT) have been implicated in the regulation of social behaviors. The purpose of the present study was to examine hormonal substrates of aggression and affiliation in the female Mongolian gerbil (Meriones unguiculatus), a highly social, monogamous rodent. Sexually naive adult females were paired with sexually experienced males for 48 h and their interactions videota...

Humans are intrinsically social animals, forming enduring affiliative bonds [1]. However, a striking minority with psychopathic traits, who present with violent and antisocial behaviors, tend to value other people only insofar as they contribute to their own advancement [2, 3]. Extant research has addressed the neurocognitive processes associated with aggression in such individuals, but we know...

• We tested the effect of an affiliation goal on spontaneous trait inference (STI). • We found a positivity bias in STIs in response to an affiliation goal. • Those with the goal formed more positive (vs. negative) STIs compared to controls. • This positivity bias persisted when the goal was unfulfilled versus fulfilled. • We conclude that STIs form flexibly in response to perceivers' social go...

This longitudinal study examined trajectories of change in adolescents' perceptions of four dimensions of school climate (academic support, behavior management, teacher social support, peer social support) and the effects of such trajectories on adolescent problem behaviors. We also tested whether school climate moderated the associations between deviant peer affiliation and adolescent problem ...

Kinship shapes female social networks in many primate populations in which females remain in their natal group to breed. In contrast, it is unclear to which extent kinship affects the social networks in populations with female dispersal. Female Colobus vellerosus show routine facultative dispersal (i.e., some females remain philopatric and others disperse). This dispersal pattern allowed us to ...

Our society contains all types of organizations, such as companies, research groups and hobby clubs. Affiliation networks, as a large and important portion of social networks, consist of individuals and their affiliation relations: Two individuals are connected by a link if they belong to the same organization(s). Affiliation networks naturally contain many fully connected cliques, since the no...

In social species, conflict with outsiders is predicted to affect within-group interactions and thus influence group dynamics and the evolution and maintenance of sociality. Although empirical evidence exists for a relationship between out-group conflict and intragroup behavior in humans, experimental tests in other animals are rare. In a model fish system, we show that simulated out-group intr...
