A taxonomic study of aggression in institutionalized delinquents

The taxonomy of aggressive behavior has been studied by many social scientists. In the present study this topic is approached empirically. A group of convicts were asked to quantify pairwise dissimilarity among aggressive social situations. The data obtained were processed by Multidimensional Scaling. The results show the necessity of taking into account 3 dimensions (justifiability, instrumentality and degree of involvement with the victim) in distinguishing among aggressive episodes. This finding is discussed in terms of cultural differences, and the usefulness of the perception of aggressive episodes as a basis for a taxonomic system is proposed.     

Rape Myth Acceptance in Sexually Assaulted Adolescents' School Contexts: Associations with Depressed Mood and Alcohol Use

High school students exposed to sexual assault (SA) are at risk for negative outcomes like depressed mood and high‐risk drinking. Although evidence suggests that both social contexts and internalized stigma can affect recovery from SA, no research to date has directly examined the presence of stigma in social contexts such as high schools as a correlate of adjustment after SA. In this study, the self‐reported rape myth acceptance (RMA) of 3080 students from 97 grade cohorts in 25 high schools was used to calculate grade‐mean and school‐mean RMA, which was entered into multilevel models predicting depressed mood and alcohol use among N = 263 SA survivors within those schools. Two forms of RMA were assessed (i.e., rape denial and traditional gender expectations). Results indicate that higher grade‐mean rape denial was associated with higher risk for depressed mood among high school boys and girls exposed to SA, and higher grade‐mean traditional gender expectations were associated with higher risk for alcohol use among girls exposed to SA. Survivors' own RMA and school‐level RMA were not significantly associated with their depressed mood or alcohol use. Although causality cannot be concluded, these findings suggest that interventions that reduce stigma in social contexts should be explored further as a strategy to improve well‐being among high‐school‐aged survivors of SA.     

Peer Influence in Elementary School: The Importance of Assessing the Likeability of Popular Children

Abstract

We examined the degree to which children perceive influence behaviors and influence over social norms from different types of high-status children to vary in a sample of 453 3^rd through 5^th grade children. Using a cluster analysis of peer-nominated popularity and likeability measures, we identified a seven-cluster solution, including three high-status clusters: Well-Liked, Popular, and Popular/Well-Liked. Popular children were perceived as using ridicule and having influence over misbehavior. Popular/Well-Liked children were perceived as using playful teasing and modeling and influencing over trend-setting and sports norms, at a degree similar to Popular children. However, Popular/Well-Liked children were not perceived as using ridicule or influencing over misbehavior; rather, they scored higher than all other status groups for prosocial assertion and academic motivation. Well-Liked children were perceived as using prosocial assertion and influencing over academic motivation at a higher degree than Average children but at a lower degree than Popular or Popular/Well-Liked children. Although the influence associated with likeability alone appeared relatively limited, likeability in conjunction with popularity seems to make a difference regarding influence behaviors and norms. A person-centered approach that takes into account multiple facets of social status is likely to enhance understanding of high-status children’s influence on their same-age peers.     

Coping with Social Stress: Implications for Psychopathology in Young Adolescent Girls

This study investigated the impact of social stress on symptoms of psychopathology at the entry into adolescence (111 girls, Mage = 11.84, SD = 0.77). We examined whether peer stress and pubertal timing were associated with internalizing distress and aggression, and whether responses to stress and cortisol reactivity mediated or moderated these associations. Cortisol samples were collected from saliva samples during in-home visits, and the YSR was used to assess psychopathology. Interestingly, pubertal timing demonstrated a trend association with cortisol. Responses to stress mediated the association between social stress and symptoms of internalizing distress and aggression. Specifically, early maturers and girls with higher levels of peer stress exhibited more problematic responses to stress, in turn demonstrating higher levels of internalizing distress and aggression. Significant moderation effects also emerged. For example, early maturers who experienced higher levels of emotional/cognitive numbing in response to peer stress were at greater risk for aggression. Findings identify coping strategies that may be used in evidence-based programming to help girls transition more successfully into adolescence will be discussed.

A social neuroscience perspective on adolescent risk-taking

This article proposes a framework for theory and research on risk-taking that is informed by developmental neuroscience. Two fundamental questions motivate this review. First, why does risk-taking increase between childhood and adolescence? Second, why does risk-taking decline between adolescence and adulthood? Risk-taking increases between childhood and adolescence as a result of changes around the time of puberty in the brain’s socio-emotional system leading to increased reward-seeking, especially in the presence of peers, fueled mainly by a dramatic remodeling of the brain’s dopaminergic system. Risk-taking declines between adolescence and adulthood because of changes in the brain’s cognitive control system—changes which improve individuals’ capacity for self-regulation. These changes occur across adolescence and young adulthood and are seen in structural and functional changes within the prefrontal cortex and its connections to other brain regions. The differing timetables of these changes make mid-adolescence a time of heightened vulnerability to risky and reckless behavior.     

How interviewers' nonverbal behaviors can affect children's perceptions and suggestibility

We conducted two studies to examine how interviewers' nonverbal behaviors affect children's perceptions and suggestibility. In the first study, 42 8- to 10-year-olds watched video clips showing an interviewer displaying combinations of supportive and nonsupportive nonverbal behaviors and were asked to rate the interviewer on six attributes (e.g., friendliness, strictness). Smiling received high ratings on the positive attributes (i.e., friendly, helpful, and sincere), and fidgeting received high ratings on the negative attributes (i.e., strict, bored, and stressed). For the second study, 86 8- to 10-year-olds participated in a learning activity about the vocal chords. One week later, they were interviewed individually about the activity by an interviewer adopting either the supportive (i.e., smiling) or nonsupportive (i.e., fidgeting) behavior. Children questioned by the nonsupportive interviewer were less accurate and more likely to falsely report having been touched than were those questioned by the supportive interviewer. Children questioned by the supportive interviewer were also more likely to say that they did not know an answer than were children questioned by the nonsupportive interviewer. Participants in both conditions gave more correct answers to questions about central, as opposed to peripheral, details of the activity. Implications of these findings for the appropriate interviewing of child witnesses are discussed.     

The effect of classroom environment on problem behaviors: A twin study

Children's behavior problems, both internalizing and externalizing, are a function of both genetic and environmental influences. One potentially important environmental influence is the classroom environment. This study of 1941 monozygotic twin pairs examined whether children whose parents rated them as similarly high or low on a number of problem behaviors were rated in the same way by teachers when they were together versus separated in their classrooms at school. Results showed that twins in the same classrooms were rated by their teachers more similarly on each dimension of problem behavior than were twins who were separated into different classrooms, suggesting that the classroom environment is important in predicting differences between twins in terms of problem behaviors at school. In addition, parents' ratings of problem behaviors were lower for twins placed in the same classroom versus twins in different classrooms. Thus, there is reason to consider whether, at least during the early school years, parents should be allowed to make the decision to not separate twins at school.     

Teachers' views and beliefs about bullying: Influences on classroom management strategies and students' coping with peer victimization

A multilevel design was used to test a model in which teachers' attitudes (beliefs) about bullying (e.g., it is normative; assertive children do not get bullied; children wouldn't be bullied if they avoided mean kids) were hypothesized to influence if and how they intervene in bullying interactions. In turn, it was hypothesized that teachers' strategies would influence how their students cope with victimization and the frequency of victimization reported by their students. Data were gathered on 34 2nd and 4th grade teachers and 363 ethnically-diverse students (188 boys; 175 girls; M age = 9 years 2 months). Results indicated that teachers were not likely to intervene if they viewed bullying as normative behavior, but were more likely to intervene if they held either assertion or avoidant beliefs. Moreover, avoidant beliefs were predictive of separating students which was then associated both directly and indirectly (via reduced revenge seeking) with lower levels of peer victimization. No grade differences emerged for teachers' views or management strategies; however, minor sex differences were detected which will be discussed.     

Peer influence and adolescent nonsuicidal self-injury: A theoretical review of mechanisms and moderators

Nonsuicidal self-injury (NSSI) is an increasingly prevalent health risk behavior among adolescents and represents a significant public health concern. Although researchers have identified numerous antecedents or risk factors that precede engagement in NSSI behaviors, few studies have examined the role of peer influence processes. Yet, recent research suggests that adolescents may be more likely to engage in NSSI when close friends or other peers engage in similar behaviors. The following paper reviews past research on peer influence effects, including potential mechanisms and moderating variables. Methodological considerations for future research on peer influence and NSSI are discussed.
