The Role of Child Characteristics and Peer Experiences in the Development of Peer Cooperation

Cooperation with peers is challenging for young children, and there are large individual differences in the development of cooperation. The roles of child characteristics and peer experiences for peer interaction during free play have been studied extensively, but it is unclear which factors predict young children's successful cooperation at different points in development. In this study, 2‐, 3‐, and 4‐year‐old children were observed during a peer cooperation task. Both their interactive behavior and cooperation success were examined, and the association of these variables with child characteristics and peer experiences was explored. Results showed that successful peer cooperation increased with age. Moreover, early individual differences in peer cooperation were related to temperamental characteristics, and, among older children, the rate of cooperation was related to prior peer experience.     

Infants Protest Their Mothers' Attending to an Infant-Size Doll

Twelve-month old infants (N = 76) experienced 4 situations of unresponsiveness in which their mothers and a stranger directed positive attention toward a doll or a picture book while they ignored the infant. Infants demonstrated more protest, negative vocalizations and inhibited play during the doll condition, particularly if the doll was held by the mother. Infant contacts with the mother were more frequent when the mother held the doll. Infants' distress during the mother/doll condition was interpreted as jealousy.     

Is preventing peer victimization sufficient? The role of prosocial peer group treatment in children's socioemotional development

Despite extensive research on the harmful effects of peer victimization, little is known about whether prosocial treatment from peers contributes to healthy socioemotional development. To address this issue, 366 third and fourth graders (170 boys; M _age = 9.34) were followed over three time points. Children completed measures of prosocial peer treatment, peer victimization, depressive affect, and friendship quality. Teacher‐reports of depressive affect and peer‐reports of aggression, victimization, and friendships were also obtained. Controlling for peer victimization, number of friends, and friendship quality, prosocial peer treatment negatively predicted depressive affect. For boys, prosocial peer treatment mediated the association between victimization and teacher‐reported depressive affect. These findings underscore the importance of prosocial peer group treatment and the need to broaden the goals of anti‐bullying interventions to include the promotion of positive peer interactions.     

Adolescent Emotion Socialization: A Longitudinal Study of Friends' Responses to Negative Emotions

Although peer influences are thought to be critically important to adolescent development, there is a paucity of research investigating the emotion socialization practices that take place between adolescents. This longitudinal study evaluated close friends' responses to negative emotion using a newly developed assessment tool of peer emotion socialization, you and your friends. Adolescent participants (N = 205) exhibiting a range of internalizing and externalizing problems between 11 and 17 years of age were assessed and re‐evaluated two years later. Participants were asked to rate the frequency with which their friends responded to them by encouraging, distracting, matching, ignoring, overtly victimizing, and/or relationally victimizing their emotions. The results indicated high levels of internal consistency and moderate levels of long‐term stability. Close friends most often responded supportively to the participants' emotional displays, but these responses differed by gender. Also, friends' emotion socialization responses were concurrently and predictively associated with participant problem status. This study contributes to a better understanding of the processes by which adolescents' emotions are socialized by their friends and has important implications for future prevention and intervention efforts.     

Sticks and Stones: The Effects of Teasing on Psychosocial Functioning in an Overweight Treatment-seeking Sample

This self-report and observational study explores the relationship between perceptions of different kinds of teasing experiences and psychosocial functioning in an overweight treatment-seeking adolescent population. Participants were 96 adolescents enrolled in a residential weight-loss camp program. Prior to the start of treatment, participants' weight status was measured by trained program staff, and participants' perceptions of teasing experiences and psychosocial functioning were assessed through self-report questionnaires. Controlling for body mass index, more frequent and upsetting weight-related teasing experiences were associated with worse psychological functioning. Adolescents most distressed by weight-related teasing exhibited lower self-esteem and higher depressive symptoms regardless of reported frequency of weight-related teasing. Competence-related teasing was also associated with more worries about weight, greater depressive symptoms, and more negative anti-fat attitudes. Weight-related teasing, but not competence-related teasing, was associated with lower levels of program and social involvement for heavier adolescents.     

Adolescent Sexual Debut: A Multi-System Perspective of Ethnic and Racial Differences

Data from the 1997 cohort of the National Longitudinal Survey of Youth were used to assess the association between family, self, proximate extra-familial, and distal extra-familial system factors and abstinence/virginity and age of first sexual intercourse by ethnicity and race (N = 1,854). Findings show how and in what circumstances measures associated with these four factors vary for Black, White, and Hispanic youth. Findings point to the robustness of class and gender for each ethnic-racial group on timing of sexual initiation and of delinquency and negative peer relations on abstinence among Black and White youth and of religious affiliation among Hispanic youth.     

Cooperative Problem-Solving and Teaching in Preschoolers

The current study investigated the ontogenetic origins of children's skills of cooperative problem-solving in a task involving two complementary roles. Participants were peer dyads of 24, 30, 36, and 42 months of age. Primary dyads were initially presented with an instrumental problem whose solution required them to cooperate by coordinating two complementary actions. To further investigate their understanding of the task, these same dyads were then presented with the same problem but with roles reversed. Finally, after each of these primary participants had demonstrated proficiency in both roles, each was separately paired with a naive peer and given the opportunity to teach the naive partner the task. A clear ontogenetic trend emerged. Even with adult assistance, 24-month-old children never became independently proficient at the task. Thirty-and 36-month-old children became proficient mostly independently, but only relatively slowly and without demonstrating extensive amounts of behavioral coordination or the use of explicitly directive language to facilitate coordination. Although they did show evidence of recognizing when a peer was new to the task, children of this age engaged in little explicit teaching of naive peers. In contrast, 42-month-old children mastered the task much more quickly than the other children, responded much more quickly and accurately when their roles were reversed, coordinated both their actions and language in the task to a much greater extent, and engaged in more explicit teaching of naïve peers. Results are discussed in terms of the developing social cognitive skills that enable children from 2 to 4 years of age to understand other persons as mental agents with whom they may share mental perspectives.     

Peers’ emotionality and children's academic achievement in second grade: Testing the moderating role of children's behavioral self-regulation

Although there is interest in the role of peers in children's schooling experiences, few researchers have examined associations and related underlying processes between peers’ emotionality, an aspect of temperament, and children's academic achievement. This study evaluated whether target children's (N = 260) own self-regulation, assessed with two behavioral measures, served a moderating function for associations between peers’ emotionality and children's own academic achievement in second grade. There was a positive association between peers’ positive emotionality and reading scores for children with higher self-regulation. Peers’ negative emotionality was negatively related to target children's reading scores, particularly for children with higher self-regulation levels, but was unrelated to math scores. Peers’ positive and negative emotionality did not predict math scores, and there was no strong evidence for the moderating role of target children's self-regulation in this association. This study highlights the potential role of children's self-regulation in modulating peer effects on academic achievement, particularly reading.     

A qualitative study of smoking cessation experiences and perceptions among homeless young adults

Up to 70% of homeless youth smoke, but there is little information available on their smoking cessation experiences and perceptions to guide cessation intervention efforts. This study examined reasons for quitting smoking, previous experiences quitting smoking, and preferences for smoking cessation programs among homeless young adults. Four focus groups (N?=?27) were conducted in centers serving homeless 18–25 year olds in Los Angeles. Sessions were audio recorded, transcribed, and analyzed by a systematic procedure for qualitative analysis to identify key themes on the topics of interest. The short-term health-related consequences of smoking and high cost of cigarettes were the main reasons participants indicated for quitting or wanting to quit. In terms of barriers to quitting, exposure to peers who smoke and smoking to cope with the daily stressors of homelessness were the two most salient themes. Suggested features of a smoking cessation program for homeless youth included having a group-based component to provide support, offering incentives to attend, and using “scare tactics” as a tool to increase motivation to quit. To increase acceptability and uptake, smoking cessation programs for homeless youth need to focus on the short-term consequences of smoking and harness of the power of peer influences.     

Implicit Theories of Peer Relationships

This research investigated the role of children's implicit theories of peer relationships in their psychological, emotional, and behavioral adjustment. Participants included 206 children (110 girls; 96 boys; M age =  10.13 years, SD =  1.16) who reported on their implicit theories of peer relationships, social goal orientation, need for approval, depressive and aggressive symptoms, and exposure to peer victimization. Parents also provided reports on aggressive symptoms. Results confirmed that holding an entity theory of peer relationships was associated with a greater tendency to endorse performance-oriented social goals and to evaluate oneself negatively in the face of peer disapproval. Moreover, entity theorists were more likely than incremental theorists to demonstrate depressive and aggressive symptoms when victimized. These findings contribute to social–cognitive theories of motivation and personality, and have practical implications for children exposed to peer victimization and associated difficulties.
