Predicting change in neural activity during social exclusion in late childhood: The role of past peer experiences.

A painful experience affecting many children is social exclusion. The current study is a follow-up study, investigating change in neural activity during social exclusion as a function of peer preference. Peer preference was defined as the degree to which children are preferred by their peers and measured using peer nominations in class during four consecutive years for 34 boys. Neural activity was assessed twice with a one-year interval, using functional MRI during Cyberball (MageT1 = 10.3 years, MageT2 = 11.4 years). Results showed that change in neural activity during social exclusion differed as a function of peer preference for the a-priori defined region-of-interest of the subgenual anterior cingulate cortex (subACC), such that relatively lower history of peer preference was associated with an increase in activity from Time1 to Time2. Exploratory whole brain results showed a positive association between peer preference and neural activity at Time2 in the left and right orbitofrontal gyrus (OFG). These results may suggest that boys with lower peer preference become increasingly sensitive to social exclusion over time, associated with increased activity in the subACC. Moreover, lower peer preference and associated lower activity within the OFG may suggest decreased emotion regulation as a response to social exclusion.

Reciprocal associations between teacher-student relations and students' externalizing behavior in elementary education? A within-dyad analysis.

The goal of this study was to investigate the transactional link between the affective quality of teacher-student relations and students' externalizing behavior in upper elementary education. We studied teacher support and conflict separately and examined whether associations differed for boys and girls. Data were collected from 1452 Dutch fifth graders (Mage = 10.60 years) at three time points within one school year, including peer nominations of teacher-student relationships and external observations of teacher-student interactions. We used random-intercept cross-lagged panel models to examine the associations within the school year. Student behavior and teacher conflict and support were clearly interrelated within measurement moments. That is, within each time point, deviations from students' typical level of externalizing behavior were associated with deviations in teacher conflict and support in teacher-student relations. In contrast to earlier work, we found no transactional link between students' externalizing behavior and their relationships and interactions with their teacher over time, neither for teacher conflict nor for support. However, for boys, an association was found between externalizing behavior and later increased teacher conflict. We concluded that it remains important to invest in supportive teacher-student relations to prevent increasing conflict and that transactionality may occur within shorter time intervals.

Neural mirroring and social interaction: Motor system involvement during action observation relates to early peer cooperation.

Whether we hand over objects to someone, play a team sport, or make music together, social interaction often involves interpersonal action coordination, both during instances of cooperation and entrainment. Neural mirroring is thought to play a crucial role in processing other's actions and is therefore considered important for social interaction. Still, to date, it is unknown whether interindividual differences in neural mirroring play a role in interpersonal coordination during different instances of social interaction. A relation between neural mirroring and interpersonal coordination has particularly relevant implications for early childhood, since successful early interaction with peers is predictive of a more favorable social development. We examined the relation between neural mirroring and children's interpersonal coordination during peer interaction using EEG and longitudinal behavioral data. Results showed that 4-year-old children with higher levels of motor system involvement during action observation (as indicated by lower beta-power) were more successful in early peer cooperation. This is the first evidence for a relation between motor system involvement during action observation and interpersonal coordination during other instances of social interaction. The findings suggest that interindividual differences in neural mirroring are related to interpersonal coordination and thus successful social interaction.

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 relationships. Furthermore, mixed models regression analyses indicated that hostile attributional biases toward a particular peer were related to directly observed reactive aggression toward that peer even after controlling for actor and partner effects, suggesting that these phenomena are dyadic or relationship oriented. On the other hand, the relation between outcome expectancies for aggression and the display of proactive aggression appeared to be more actor driven and partner driven that dyadic.

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 the social relations model was used, relationship effects accounted for equally as much of the variance in total aggression and proactive aggression as either actor or target effects. Mutually aggressive dyads displayed twice as much total aggression as randomly selected dyads. Members of mutually aggressive dyads attributed greater hostile intentions toward each other than did randomly selected dyads, which may serve to explain their greater aggression toward each other. The importance of studying relational factors, including social histories and social-cognitive processes, is discussed.

Social-cognitive and behavioral correlates of aggression and victimization in boys' play groups.

A contrived play group procedure was utilized to examine the behavioral and social-cognitive correlates of reactive aggression, proactive aggression, and victimization via peers. Eleven play groups, each of which consisted of six familiar African-American 8-year-old boys, met for 45-min sessions on five consecutive days. Social-cognitive interviews were conducted following the second and fourth sessions. Play group interactions were videotaped and examined by trained observers. High rates of proactive aggression were associated with positive outcome expectancies for aggression/assertion, frequent displays of assertive social behavior, and low rates of submissive behavior. Reactive aggression was associated with hostile attributional tendencies and frequent victimization by peers. Victimization was associated with submissive behavior, hostile attributional bias, reactive aggression, and negative outcome expectations for aggression/assertion. These results demonstrate that there is a theoretically coherent and empirically distinct set of correlates associated with each of the examined aggression subtypes, and with victimization by peers.

Low vision aids for visually impaired children: a perception-action perspective.

It is a widely accepted belief in clinical practice that children with a visual impairment can profit from the use of a low vision aid (LVA). However, we found a considerable gap in our scientific understanding of LVA use, particularly in young children. This is the reason for the analysis presented in this paper. A selected overview of LVA use in adults is given, from which valuable insights are taken. Additionally, an action perspective for analysing LVA use is discussed as well as the results of tool-use studies in children. Mainly based on these three ingredients, we developed a conceptual framework for LVA use. The framework consists of three interacting relations between LVA, child and task. Performance of a particular child on a specific task with a certain LVA is constrained by the following three reciprocal and dynamic relations: the Child-to-Task relation (related to goal-information), the Child-to-LVA relation (related to control-information), and the LVA-to-Task relation (related to topology information).

Group social context and children's aggressive behavior.

Very little is known about the influence of the social-psychological context on children's aggressive behavior. The purpose of this research was to examine the interrelations of group contextual factors and the occurrence of aggressive behavior in 22 experimental play groups of 7- and 9-year-old African-American boys. Group context was examined before, during, and after an aggressive act as well as during nonaggressive periods. The results showed that there are dimensions of group context (i.e., negative affect, high aversive behavior, high activity level, low group cohesion, competitiveness) that were related to the occurrence of aggressive behavior between 2 children in the group. Group context influenced how children reacted to aggression between its members (e.g., siding with the victim), which in turn influenced the quality of the postaggression group atmosphere. This study suggests that individual-within-context information be incorporated into theories of aggression among children.
