The present study examined age-related differences in bystander reactions within the context of peer exclusion of national ingroup (British) and immigrant outgroup (Australian or Turkish) peers. The immigrant peers were from nations that varied in terms of their perceived intergroup status in Britain. Participants were British children (n = 110, 8-11 years) and adolescents (n = 193, 13-16 years) who were presented with one of three scenarios in which either a British national, Australian immigrant or Turkish immigrant peer was excluded by a British peer group. Participants indicated their bystander responses. Perceived similarity and bystander self-efficacy were examined as possible correlates of bystander reactions. Findings revealed that children were more likely to directly challenge the social exclusion when the excluded peer was British or Australian compared to when they were Turkish. In contrast, adolescents did not differentiate in their response - they were equally likely to directly challenge the exclusion regardless of the excluded peer's nationality. Importantly, when the excluded peer was Turkish, moderated mediation analysis showed that, with age, there was higher bystander self-efficacy for challenging the exclusions. In turn, higher bystander self-efficacy was related to higher direct challenging. These novel findings demonstrate the importance of intergroup relations, perceived similarity and bystander self-efficacy in the emergence of age-related differences in bystander reactions to the exclusion of immigrant peers [219 words].

The frequency and length of games, conflicts, and contingency sequences that took place between toddlers as they got to know one another were studied using archival data. The sample consisted of 28 unfamiliar 20- and 30-month-old toddlers (predominantly White, 16 males) who met separately with each of two other toddlers for 18 play dates. The frequency of games increased over time, while the frequency of conflict and contingency sequences decreased. The length of games increased over time while the length of conflicts and contingency sequences were stable. Age and language ability predicted changes in frequency and length of the different types of sequences. Thus, toddlers engage in less structured interactions when they first meet; their interactions become increasingly more organized and positive as the relationship evolves.

Adolescence is characterized by frequent emotional challenges, intense emotions, and higher levels of expressive suppression use than found in older populations. While evidence suggests that contingent expressive suppression use based on context is the most functional, it remains unclear whether adolescents use expressive suppression differentially based on social context. Because the peer relationship is highly salient in adolescence, the current study was designed to assess whether adolescents use expressive suppression differentially based on their social context. Adolescents (N = 179, M_age  = 13.94, 49.2% female) reported emotional events using experience sampling via a smartphone application for 14 days. Multilevel modeling revealed that adolescents used less expressive suppression when they were alone compared with when they were with people, and used more expressive suppression when they were with their peers compared with when they were with family. In addition, more closeness with family predicted less overall expressive suppression use, while closeness with peers did not influence the level of expressive suppression use within the peer context. We discuss the importance of peer relations in adolescence and the relationship between closeness and emotional expression.
