Cultural group identity and group norms are significantly related to social exclusion evaluations (Bennett, ). This study examined 241 Jewish-American mid (M = 14.18 years, SD = 0.42) to late (M = 17.21 years, SD = 0.43; MageTOTAL  = 15.54 years, SD = 1.57) adolescents' cultural identities and contextually salient perceived group norms in relation to their evaluations of Arab-American inclusion...

BACKGROUND Research on adolescent development suggests that peer influence may play a key role in explaining adolescents' willingness to drink, an important predictor of drinking initiation. However, experiments that thoroughly examine these peer influence effects are scarce. This study experimentally examined whether adolescents adapted their willingness to drink when confronted with the pro-a...

Obesity contributes to 2.8 million deaths annually, making interventions to promote healthy eating critical. Although preliminary research suggests that social norms influence eating behavior, the underlying psychological and neural mechanisms of such conformity remain unexplored. We used fMRI to investigate whether group norms shift individuals' preferences for foods at both behavioral and neu...

BACKGROUND Although neighborhoods with more collective efficacy have better health in general, recent work suggests that social norms and collective efficacy may in combination influence health behaviors such as smoking. METHODS Using data from the New York Social Environment Study (conducted in 2005; n=4000), we examined the separate and combined associations of neighborhood collective effic...

In multiagent systems, social norms is a useful technique in regulating agents’ behaviors to achieve coordination or cooperation among agents. One important research question is to investigate how a desirable social norm can be evolved in a bottom-up manner through local interactions. In this paper, we propose two novel learning strategies under the collective learning framework: collective lea...

Differential association and social learning theory assume delinquent peers to be instigators and reinforcers of delinquent behaviour and norms favourable of delinquency. Control theory, on the other hand, assumes that delinquents will group together with peers that share a common normative and behavioural background. Interactional theory as an integrative paradigm argues that both – influence ...

Background Evidence suggests adolescent self-esteem is influenced by beliefs of how individuals in their reference group perceive them. However, few studies examine how gender- and violence-related social norms affect self-esteem among refugee populations. This paper explores relationships between gender inequitable and victim-blaming social norms, personal attitudes, and self-esteem among adol...

Experimental and cross-sectional studies indicate that perceptions of the eating and drinking behavior of one's peers (perceived descriptive peer norms) are associated with the types, frequency and quantity of food, and beverages a person chooses to consume. At present, we know very little about the longitudinal association between perceived descriptive peer norms and future eating or drinking ...
