A Meta‐Analysis of Susceptibility to Peer Influence Effects in Adolescence: The Role of Method of Influence and Type of Behavior
INTRODUCTION: Decades of research have extensively explored how and why adolescents alter their behaviors to align with their peers. This meta-analysis aimed to: (1) assess the degree to which adolescents are influenced by their peers in experimental studies of immediate behavioral outcomes and (2) explore potential moderators of susceptibility to peer influence, including the method of peer influence (feedback, norms, presence) and the type of b…
The role of changes in peer victimization from elementary to high school and autonomic reactivity on adolescent reactive aggression
The goals of the present study were to investigate links between changes in peer victimization from elementary to high school and adolescent reactive aggression (Goal 1), whether heightened autonomic nervous system (ANS) reactivity to social and nonsocial stress increases risk for adolescent reactive aggression (Goal 2), and whether increased ANS reactivity strengthens the association between changes in victimization and adolescent reactive aggre…
The importance of both individual differences and dyadic processes in children’s emotion expression
Although children display strong individual differences in emotion expression, they also engage in emotional synchrony or reciprocity with interaction partners. To understand this paradox between trait-like and dyadic influences, the goal of the current study was to investigate children's emotion expression using a Social Relations Model (SRM) approach. Playgroups consisting typically of four same-sex unfamiliar nine-year-old children ( N = 202) …
Emotion transmission in peer dyads in middle childhood
This study investigated emotion transmission among peers during middle childhood. Participants included 202 children (111 males; race: 58% African American, 20% European American, 16% Mixed race, 1% Asian American, and 5% Other; ethnicity: 23% Latino(a) and 77% Not Latino(a); M income = $42,183, SDincome = $43,889; M age = 9.49; English-speaking; from urban and suburban areas of a mid-Atlantic state in the United States). Groups of four same-sex …
Children’s social information processing predicts both their own and peers’ conversational remarks
The goal of the current study was to investigate whether children's social information processing (SIP) predicts their conversations with peers, including both their remarks to peers and peers' remarks to them. When children ( N = 156; 55% male; United States; Representation by Race: 60% African American, 18% Mixed race, 15% European American, 7% Other; Representation by Latino/a Ethnicity: 22% Latino/a, 78% Not Latino/a; M income = $39,419) were…
Individual differences and dyadic processes in conversations with peers in middle childhood
The goal of the current study was to investigate the contribution of both trait‐like individual differences and dyadic processes to the content of children's conversations. Fifty‐two groups typically consisting of four same‐sex unfamiliar nine‐year‐old children ( N = 202) interacted in all possible dyads, resulting in six dyads per group. Each dyad completed a 5‐min frustration task and a 5‐min planning task. Observers coded children's verbalizat…
Attachment Disorganization in Infancy: A Developmental Precursor to Maladaptive Social Information Processing at Age 8
This study examined infant attachment as a predictor of social information processing (SIP) in middle childhood (n = 82) while controlling for parental sensitivity in middle childhood. Attachment quality was assessed using the Strange Situation. Although attachment insecurity did not predict SIP, attachment disorganization positively predicted the early SIP steps of hostile attributional bias and aggressive goals. Children with disorganized attac…
Bidirectional relations between internalizing symptoms and peer victimization in late childhood
The present study investigated bidirectional relations between peer victimization and internalizing symptoms, with a focus on three forms of victimization (physical, verbal, relational) and two types of internalizing symptoms (depressive, anxious). In the fall and spring, children ( N = 1,264–1,402 fourth and fifth graders depending on time point and data source) reported on their victimization, and teachers reported on children’s depressive and …
Parental advice to preadolescent bystanders about how to intervene during bullying differs by form of bullying
The current study examined parental advice given to fourth‐ and fifth‐grade preadolescents who imagined being bystanders to different forms of bullying (physical, verbal, property attack, social manipulation, exclusion). We assessed the frequency with which parents advised youth to follow specific intervention strategies (stop the bully, help/comfort the victim, tell adults), and we tested whether the frequency by which parents provided each kind…
The simultaneous assessment of and relations between children's sympathetic and parasympathetic psychophysiology and their reactive and proactive aggression
The goal of the current study was to examine the link between children's psychophysiology and aggression when both constructs were assessed simultaneously in scenarios designed to provide the opportunity to aggress for either a reactive reason or a proactive reason. Both sympathetic nervous system (SNS) activity (skin conductance) and parasympathetic nervous system (PNS) activity (respiratory sinus arrhythmia or RSA), as well as their interaction…
Dyadic accuracy and bias in preadolescents' perceived peer relations: Associations with aggression, depression, and peer victimization
The dyadic accuracy and bias of preadolescents' ( M = 10.13 years) perceived peer relations were examined in relation to their aggression, depressive symptoms, and peer victimization. A racially diverse sample (235 boys and 281 girls) completed peer nominations of perceived and actual peer acceptance and rejection, peer nominations of friendship and peer victimization, and a self-report measure of depressive symptoms. Teachers completed measures …
Reactive and Proactive Aggression in Childhood and Adolescence: Precursors, Outcomes, Processes, Experiences, and Measurement
This paper reviews and critiques the growing literature on the distinction between reactive and proactive aggression in children and adolescents. Empirical findings suggest that the subtypes of aggression are (a) preceded by different familial precursors, (b) associated with different behavioral outcomes, (c) driven by different social–cognitive and emotional processes, and (d) related to different social experiences. Because measurement difficul…
Connections between parents' friendships and children's peer relationships
This study investigated connections between qualities of parents' own friendships and children's negative peer relationships (i.e., aggression and peer rejection). Participants were 57 dyads of second-grade children (29 girls and 28 boys; mean age = 7.6 years) and their parents. Data on child aggression were collected from teachers and peers, and child peer rejection was assessed using unlimited peer nominations. Parents reported on their own fri…
Sleep Disturbances and Correlates of Children with Autism Spectrum Disorders
The Relations among Observational, Physiological, and Self‐Report Measures of Children's Anger
Our first goal was to examine the relations among observational, physiological, and self‐report measures of children's anger. Our second goal was to investigate whether these relations varied by reactive or proactive aggression. Children (272 second‐grade boys and girls) participated in a procedure in which they lost a game and prize to a confederate who cheated. Skin conductance reactivity, heart rate reactivity, self‐reports of anger, angry fac…
Children's Use and Knowledge of Display Rules for Anger Following Hypothetical Vignettes versus Following Live Peer Interaction
Our primary goal was to examine the correspondence between children’s self‐reported use and knowledge of display rules for anger following hypothetical vignettes versus following live peer interactions. Our secondary goal was to investigate whether children’s self‐reported experience and self‐reported expression of anger were related their observed anger expression, considered an observational measure of use of display rules for anger. Participan…
The dyadic nature of social information processing in boys' reactive and proactive aggression
The correlation between boys' social cognitions and their aggressive behavior toward peers was examined as being actor driven, partner driven, or dyadic relationship driven. Eleven groups of 6 familiar boys each (N = 165 dyads) met for 5 consecutive days to participate in play sessions and social-cognitive interviews. With a variance partitioning procedure, boys' social-cognitive processes were found to vary reliably across their dyadic relations…
It takes two to fight: A test of relational factors and a method for assessing aggressive dyads
Observations of aggressive interactions in boys' laboratory play groups were used to evaluate the relative importance of relational and individual factors in accounting for aggressive acts. A classroom peer-rating method for identifying mutually aggressive dyads was validated in 11 5-session play groups, composed of 2 mutually aggressive boys and 4 randomly selected male classmates from 11 predominately African American 3rd-grade classrooms. When…
Social-Cognitive and Behavioral Correlates of Aggression and Victimization in Boys' Play Groups
Children's Friends and Behavioral Similarity in Two Social Contexts
The general purpose of this study was to examine similarity between friends with respect to behavior. The specific goals were to consider; 1) different sources of evaluation (peer ratings and direct observations); 2) different social contexts (classroom and play group); and 3) different subtypes of aggressive behavior (proactive and reactive aggression). In the first phase of the study, sociometric assessments and peer evaluations of behavior wer…
