Who Dislikes Whom, and For Whom Does It Matter: Predicting Aggression in Middle Childhood

This study investigated the role of mutual dislike dyads (MDDs) in the development of aggressive behavior across the middle childhood years. Of particular interest was whether involvement in MDDs predicted later aggression, and whether the magnitude of the association between MDDs and later aggression varied based on characteristics of target children and 'others' involved in their MDDs. Data were collected on a community sample of 453 children participating in an ongoing longitudinal study. Classroom peer nomination and rating-scale measures were collected in kindergarten through third grade; aggressive behavior problems were assessed via teacher ratings in the early elementary years (kindergarten and first grade) and late elementary years (fourth and fifth grade). MDD involvement in the middle elementary years (second and third grade) was associated with higher levels of aggression in the late elementary years among boys (but not girls), and these predictions held after controlling for group-level peer disliking in the middle elementary years, aggression in the early elementary years, and demographic variables. The association between MDD involvement and subsequent aggression was also qualified by the aggressiveness of others in children's MDDs: Having more MDDs predicted later aggression only among boys whose MDDs involved mostly non-aggressive others.     

Associations between Sadness and Anger Regulation Coping, Emotional Expression, and Physical and Relational Aggression among Urban Adolescents

This study examined associations between self-reports of sadness and anger regulation coping, reluctance to express emotion, and physical and relational aggression between two cohorts of predominantly African-American fifth (N  =  191; 93 boys and 98 girls) and eighth (N  =  167; 73 boys and 94 girls) graders. Multiple regression analyses indicated unique associations between relational aggression and expressive reluctance and sadness regulation coping. In contrast, physical aggression, but not relational aggression, was associated with anger regulation coping. These relations did not differ across gender, but the strength of the association between anger regulation coping and physical aggression varied by grade. Sadness regulation coping moderated the association between expressive reluctance and relational aggression. Conversely, anger regulation coping moderated the relation between expressive reluctance and physical aggression; however, the strength of this relation differed by gender. These findings have important implications for intervention efforts.     

Children's Anger Attribution Bias: Relations to Family Environment and Social Adjustment

We examined the relations of caregiver depression and family instability to preschool children's anger attribution bias and emotion attribution accuracy on a test of emotion situation knowledge. After controlling for age, gender, and verbal ability, caregiver depression and family instability predicted children's anger attribution bias but not the overall accuracy of their emotion attributions. We also divided children into groups low and high on teacher reports of aggression and groups low and high on teacher reports of peer rejection and examined the anger attribution bias of these groups. For boys but not girls, greater anger attribution bias predicted higher levels of aggression. For all children, greater anger attribution bias predicted higher levels of peer rejection. Results suggest that the misattribution of anger to others may be an important component of some children's early emotional and social difficulties.     

Mother–Child Conversations about Emotions: Linkages to Child Aggression and Prosocial Behavior

We examined associations of maternal and child emotional discourse and child emotion knowledge with children's behavioral competence. Eighty‐five upper middle‐income, mostly White preschoolers and mothers completed a home‐based bookreading task to assess discourse about emotions. Children's anger perception bias and emotion situation knowledge were assessed in a separate interview. Children's prosocial behavior, relational aggression, and physical aggression were observed during a preschool‐based triadic play task. Mothers' emotion explanations were correlated with children's emotion situation knowledge and relational aggression. Both mothers' and children's emotion explanations predicted prosocial behavior whereas mothers' use of positive emotional themes was negatively associated with children's anger perception bias. Physical aggression was predicted by mothers' emotion comments, children's anger perception bias, and lack of emotion situation knowledge. Maternal emotion socialization variables were less strongly related to children's behavioral competence after accounting for demographics and child emotional competence. Implications of these findings for future research on emotion socialization are discussed.     

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 facial expressions, and angry nonverbal behaviors were measured for each turn of the game. We used multi‐level regressions to calculate the relations among the 10 pairs of the five anger variables over the course of the game. Six of the 10 pairs of anger variables were positively related. These findings suggest that measuring children's anger using any one approach may not capture the full complexity of children's overall experience and expression of anger. Furthermore, three of the 10 relations were stronger at higher levels of reactive aggression, although none varied by proactive aggression. These findings suggest that reactive aggression is related to greater cohesiveness in the experience and expression of anger than is proactive aggression.     

Links between friends’ behaviors and the emergence of leadership in childhood: A genetically informed study of twins

Using a genetically informed design, this study examined whether children's leadership behavior varied as a function of their reciprocal friends’ behavioral characteristics. Specifically, we tested (a) whether friends’ use of a dual strategy (specifically, indirect aggression with prosocial behavior) was associated with children's leadership behavior and (b) whether, in line with a gene‐environment interaction (GxE), the predictive association between friends’ behaviors and children's leadership behavior varied depending on the child's genetic likelihood for leadership. The sample comprised 239 Monozygotic and same‐sex Dizygotic twin pairs (50% boys) assessed in grade 4 (mean age = 10.4 years, SD = 0.26). Reciprocal friendship and children's and their friends’ prosocial, indirectly aggressive, and physically aggressive behaviors were measured via peer nominations. Children's and friends’ leadership was measured through teacher ratings. Multilevel regression analyses revealed that children's genetic likelihood for leadership was positively associated with their leadership behavior. Moreover, the higher their genetic likelihood for leadership, the more children displayed increased leadership behavior when friends showed a combination of indirect aggression and prosocial behavior (GxE). These results underline the role of friends’ behaviors in explaining children's leadership. Socializing with bistrategic friends seems to foster leadership skills especially in children with a genetic likelihood for leadership.     

Approach‐related emotion,toddlers' persistence,and negative reactions to failure

Approach behavior, defined as differences in behavior to an incentive event and anger at its removal, was assessed during contingency learning in 87 5‐month olds was related to maternal ratings of mastery behaviors at 2 years. Mothers reported on infants' concurrent temperament, as well as the occurrence of anger and tantrums, and their own anger at 12 months. Approach behavior was expected to predict persistence with objects and persistent motor behavior, but not negative reactions to failure. Negative reactions to failure were expected to be mediated by a distress‐prone temperament. The moderating effect of maternal anger on these relations was also explored using conditional process regression models. Controlling for soothability, early approach behavior predicted toddlers' persistence, especially gross motor persistence, moderated by maternal anger. With more maternal anger, approach behavior and toddler's persistence were more strongly related. Distress to limits, infant anger at 12 months, and maternal anger were significantly correlated, but only infant anger was related to negative reactions to failure. Prior to 6 months, goal‐directed behavior is related to later behavioral persistence, but maternal responses to child anger are an important contributor to this relation and by 12 months, infant anger directly predicts mastery frustration at 2 years.     

Media Violence Associations with the Form and Function of Aggression among Elementary School Children

Although the association between media violence exposure (MVE) and physical aggression (PA) has been well studied, few studies have examined the link between MVE and other subtypes of aggression. The purpose of this study was to examine the relation between MVE and reactive and proactive subtypes of both PA and relational aggression (RA). Six hundred and forty‐one third to fifth grade students reported on their exposure to media violence. RA and PA were assessed by peers and teachers. Reactive and proactive subtypes of RA and PA were assessed by teacher reports. Findings revealed a significant positive association between MVE and overall PA and RA. The relation with RA was stronger for girls than for boys. When predicting the functional subtypes of aggression, higher MVE was associated with lower reactive RA, higher proactive RA, and higher reactive PA, and MVE was unrelated to proactive PA. The implications of the findings for future research are discussed.     

Black‐White Biracial Children's Social Development from Kindergarten to Fifth Grade: Links with Racial Identification,Gender, and Socioeconomic Status

In this study, we investigated trajectories of Black‐White biracial children's social development during middle childhood, their associations with parents’ racial identification of children, and the moderating effects of child gender and family socioeconomic status (SES). The study utilized data from parent and teacher reports on 293 US Black‐White biracial children enrolled in the Early Childhood Longitudinal Study‐Kindergarten Cohort (ECLS‐K). Growth curve models suggested increasing trajectories of teacher‐reported internalizing and externalizing behaviors between kindergarten and fifth grade. Parents’ racial identification of children predicted child externalizing behavior trajectories such that teachers rated biracially identified children's externalizing behaviors lower relative to those of Black‐ and White‐identified children. Additionally, for White‐identified biracial children, the effect of family SES on internalizing behavior trajectories was especially pronounced. These findings suggest that in the USA, how parents racially identify their Black‐White biracial children early on has important implications for children's problem behaviors throughout the elementary school years.     

Maladaptive Peer Relationships and the Development of Relational and Physical Aggression During Middle Childhood

This study examined the unique roles of peer rejection and affiliation with aggressive peers in the development of relational and physical aggression in a sample of 979 2nd through 4th grade children. Information about target children and their best friends’ aggression and peer rejection was gathered via peer‐nominations when the majority of children were in the 3rd grade, and again approximately one year later. Friendships were identified by having target children nominate their three best friends in their classroom. Path analyses conducted with children who had at least one reciprocated friendship revealed that peer rejection and friends’ aggression predicted changes in target children's aggression; however, the patterns of relations varied by gender and form of aggression. Higher initial levels of rejection and friends’ relational aggression predicted increases in relational aggression among girls only, whereas rejection and friends’ physical aggression predicted increases in physical aggression among boys and girls. The significance of these results for the application of peer influence theories to relational aggression, and to females, is discussed.     

Relational Aggression, Relational Victimization, and Language Development in Preschoolers

We investigated language development, relational aggression, and relational victimization in ethnically, socioeconomically diverse preschoolers. Relational aggression was positively related to language development. Girls were more relationally aggressive than boys, and higher‐socioeconomic status (SES) children were more relationally aggressive and victimized than lower‐SES children. Neither gender nor SES conclusively moderated the relation between language and relational aggression, though some findings suggest the possibility of stronger relations among boys and lower‐SES children. Teachers agreed on ratings of relational aggression and relational victimization to a moderate extent.     

Media Exposure, Aggression and Prosocial Behavior During Early Childhood: A Longitudinal Study

Preschool children (N = 78) enrolled in multi‐informant, multi‐method longitudinal study were participants in a study designed to investigate the role of media exposure (i.e., violent and educational) on concurrent and future aggressive and prosocial behavior. Specifically, the amount of media exposure and the nature of the content was used to predict concurrent and future physical, verbal and relational aggression as well as prosocial behavior for girls and boys. This two‐year longitudinal study found that media exposure predicted various subtypes of aggression and prosocial behavior. These findings are qualified by the gender of the focal child. That is, parental reports of media exposure were associated with relational aggression for girls and physical aggression for boys at school. Ways in which these findings extend our understanding of the role of media during early childhood are discussed.     

Interplay between Friends' Aggression and Friendship Quality in the Development of Child Aggression during the Early School Years

The aim of this study was to investigate the unique and combined role of friendship quality and friends' aggression in regard to the persistence of young children's physical aggression from kindergarten to grade 2. The sample included 1555 children (808 girls) assessed annually using teacher ratings. Two theoretical perspectives (i.e., the social learning and the social bonding perspectives) served as frameworks to guide the analyses and interpret the results. In line with the social learning perspective, friends' aggression was related to a significant increase in children's physical aggression. However, in line with the social bonding perspective, good friendship quality played both a compensatory and a protective role, by, respectively, reducing children's initial level of physical aggression and by mitigating, albeit marginally, the associations between friends' and children's physical aggression. These results suggest that fostering a positive relationship between friends in the early school years may decrease physical aggression even if the friends are aggressive.     

Aggressive behaviour in at‐risk children: contribution of subjective well‐being and family cohesion

We examined the contributors to aggressive behaviour in 111 at‐risk Israeli children aged 9–13 years who attended day centres over several years to prevent removal from their homes. This non‐normative transition to a day centre represents a difficult period of change for these children, which often manifests in aggressive behaviours, at least in the short term. To elucidate predictors of aggressive behaviour, we investigated a familial variable (family cohesion) and a personal variable (subjective well‐being [SWB]) that were previously shown to correlate with various aspects of children's aggression. Children's self‐reports underscored the importance of SWB for their aggressive behaviour. SWB's cognitive component – life satisfaction – correlated significantly with all four measures of aggressive behaviour (physical violence, verbal violence, anger and hostility). SWB's emotional component – negative affect – correlated significantly with all but verbal violence. Interestingly, SWB was found to mediate the hostility dimension of aggression (as well as family cohesion). Other significant findings revealed that family cohesion correlated positively with SWB (life satisfaction and positive affect) and correlated negatively with aggression (physical violence, verbal violence, anger and hostility). Various explanations were discussed alongside implications for day care staff's individual and family interventions.     

Maternal Sensitivity Moderates the Relation between Negative Discipline and Aggression in Early Childhood

Three models regarding the relation between maternal (in)sensitivity, negative discipline, and child aggression were examined in a sample of 117 mother–child pairs with high scores on child externalizing behavior: (1) Sensitivity and discipline are uniquely related to child aggression (the additive model); (2) the relation between discipline and aggression is moderated by maternal sensitivity (the moderating model); (3) the relation between sensitivity and aggression is mediated by maternal discipline (the mediating model). Parenting and child aggression were observed when the children were on average 26.71 months old (range of 13.58 to 41.91 months) and again one year later. Results supported the moderating model. More negative discipline was related to more child aggression one year later, but only when mothers were insensitive. This finding supports the idea that the affective context is important for the impact of negative discipline on child development.     

Executive function and theory of mind as predictors of aggressive and prosocial behavior and peer acceptance in early childhood

Executive function (EF) and theory of mind (ToM) are related to children's social interactions, such as aggression and prosocial behavior, as well as their peer acceptance. However, limited research has examined different forms of aggression and the moderating role of gender. This study investigated links between EF, ToM, physical and relational aggression, prosocial behavior and peer acceptance and explored whether these relations are gender specific. Children (N = 106) between 46‐ and 80‐months‐old completed tasks assessing cool and hot EF and ToM. Teaching staff rated children's aggression, prosocial behavior, and peer acceptance. EF and ToM predicted physical, but not relational, aggression. Poor inhibition and delay of gratification were uniquely associated with greater physical aggression. EF and ToM did not predict prosocial behavior or peer acceptance. Added to this, gender did not moderate the relation between either EF or ToM and social outcomes. The correlates of aggression may therefore differ across forms of aggression but not between genders in early childhood.     

Cyber Aggression: The Relation between Online Offenders and Offline Social Competence

Children are increasingly using computer technologies to engage in acts of aggression against peers, often termed ‘cyber aggression’. Media reports have sensationalized instances of cyber aggression, and social scientists have begun to examine its characteristics and consequences. Using a younger sample of children than most previous research (192 third‐ through sixth‐grade children), the present research evaluated grade and gender effects on cyber aggression and, most importantly, evaluated the classroom peer social consequences of engaging in cyber aggression, after controlling for traditional, face‐to‐face aggression. Children reported engaging in cyber aggression at comparable rates across grades and between males and females. Engaging in cyber aggression was related to higher rates of loneliness and lower rates of global self‐worth, peer optimism, number of mutual friendships, social acceptability, and popularity. In short, after controlling for effects attributable to traditional aggression, cyber aggression was related to significant negative peer relations outcomes.     

An Integrative Examination of Peer Conflict: Children's Reported Goals, Emotions, and Behaviors

The primary purpose of the present study was to examine the interrelations among children's typical emotions, goals, and behavior during peer conflict and to examine emotions and goals as joint predictors of behavior. Children (7 to 11 years old) described recent conflicts with peers and were questioned about their emotions, goals, and behaviors. The friendliness of children's reported goals during conflict was associated with low anger intensity and with high intensity of sadness. Children who tended to report nonconstructive behavior also tended to report relatively intense anger and relatively unfriendly goals. Furthermore, in regression analyses, the friendliness of goals uniquely predicted the constructiveness of children's behavior after controlling for the effects of anger intensity, age, gender, provoking event, and friendship with the peer. Although boys and girls reported similar levels of anger and sadness, girls reported friendlier goals and more constructive behavior than did boys. The use of self‐reports of actual events to examine peer conflict during middle childhood is also discussed.     

Empathy and Observed Anger and Aggression in Five-Year-Olds

In Roberts and Strayer (1996 ), we reported that emotional expressiveness and anger were important predictors of empathy for school‐age children, and that empathy strongly predicted prosocial behaviors aggregated across methods and sources. In this paper, we report how empathy was associated with direct observations of anger and aggression in peer play groups. Twenty‐four initially unacquainted five‐year‐old children (50% girls) were randomly assigned to six same‐sex groups; each group met for three one‐hour play sessions. Physical and verbal aggression, object struggles and anger were coded from videotapes, as were prosocial and social behaviors. As expected, empathy (aggregated across methods and sources) was negatively associated with aggression and anger, and positively associated with prosocial behaviors. Although children who were more angry were also more aggressive, anger and aggression did not covary across play sessions as a simple causal model requires. These results suggest further directions for research in emotions and aggression.     

Teacher–Child Relationship Quality and Children's Peer Victimization and Aggressive Behavior in Late Childhood

This investigation examines the extent to which characteristics of the teacher–child relationship (closeness, dependency, and conflict) are predictive of changes in children's peer victimization and aggressive behavior over the course of a school year. Relational and physical forms of victimization and aggression were studied, and changes in peer acceptance and number of friendships were tested as possible mediators. Longitudinal data from 410 fourth‐ and fifth‐grade students (193 boys; 217 girls) and their teachers (N = 25) were analyzed. Whereas dependency on the teacher predicted heightened victimization from peers, a close relationship with the teacher forecasted less physical aggression toward peers. Moreover, decreases in number of friendships partially mediated the link between dependency on the teacher and heightened relational victimization for boys. These findings have implications for understanding the continuing influence of teacher–child relationships on children's social development in late childhood and for identifying interpersonal risk factors associated with involvement in peer harassment.
