Biopsychosocial Influences That Promote and Impede Social Brain Maturation

ABSTRACT

Social, emotional, and executive function systems of the brain change greatly during adolescence as the result of biopsychosocial influences. These factors alter the course of adolescent behavior through effects on the component processes of social behavior. Specifically, the influences of chronic stress, social and economic adversity, alcohol and drugs, and brain injury as well as parental buffering and support, increased neural connectivity and mentalizing resources, and enriched environments can impede or promote maturation of the social and executive brain networks that regulate social adjustment and emotional expression. Hence, there are many early “windows of opportunity” to affect the biological and neurocognitive foundations of adolescent social executive functions such as empathy, theory of mind, self-monitoring, and social emotions.     

The female advantage: sex as a possible protective factor against emotion recognition impairment following traumatic brain injury

Although moderate to severe traumatic brain injury (TBI) leads to facial affect recognition impairments in up to 39% of individuals, protective and risk factors for these deficits are unknown. The aim of the current study was to examine the effect of sex on emotion recognition abilities following TBI. We administered two separate emotion recognition tests (one static and one dynamic) to 53 individuals with moderate to severe TBI (females = 28) and 49 demographically matched comparisons (females = 22). We then investigated the presence of a sex-by-group interaction in emotion recognition accuracy. In the comparison group, there were no sex differences. In the TBI group, however, females significantly outperformed males in the dynamic (but not the static) task. Moreover, males (but not females) with TBI performed significantly worse than comparison participants in the dynamic task. Further analysis revealed that sex differences in emotion recognition abilities within the TBI group could not be explained by lesion location, TBI severity, or other neuropsychological variables. These findings suggest that sex may serve as a protective factor for social impairment following TBI and inform clinicians working with TBI as well as research on the neurophysiological correlates of sex differences in social functioning.     

Momentum in Child Compliance and Opposition

Several event-dependent properties of child-mother interactions were studied to investigate momentum in child oppositional and compliant behavior. It was hypothesized that: (a) compared to an episode of child opposition, an episode of child compliance would be related to an increased likelihood of subsequent child compliance, and (b) the association between a target episode of child opposition and the likelihood of subsequent compliance or opposition would be mediated by the history of the dyadic interaction. These hypotheses were supported. In addition, the presence of interactional sequences predictive of child compliance was inversely related to mother dysphoria and unrelated to mother-reported child externalizing behavior disorder symptoms. Discussion focuses on antecedent interactional patterns as determinants of future child behavior.     

Belief in a Just World and Jury Decisions in a Civil Rape Trial

When people's belief in a just world (BJW) is challenged, it can be restored by attributing blame to the victim or alleviating the victim's suffering. In criminal cases, jurors can attribute responsibility to victims, but cannot alleviate suffering. Participants ( n = 106) heard a taped civil rape case. The effect of age of plaintiff, gender of participant, and type of participant on mock jurors' reactions to a plaintiff were examined. Participants evaluated responsibility of plaintiff and awarded monetary damages. It was hypothesized that, given this opportunity to compensate the victim, jurors would be less likely to derogate the victim. As hypothesized, women with high and low BJW attributed the same level of responsibility to the plaintiff but those with a high BJW awarded more monetaly damages. Men with high BJW awarded much less in damages than did men with low BJW. The just-world theory appears to explain many of the decisions made by mock jurors.     

The affect heuristic in judgments of risks and benefits

This paper re‐examines the commonly observed inverse relationship between perceived risk and perceived benefit. We propose that this relationship occurs because people rely on affect when judging the risk and benefit of specific hazards. Evidence supporting this proposal is obtained in two experimental studies. Study 1 investigated the inverse relationship between risk and benefit judgments under a time‐pressure condition designed to limit the use of analytic thought and enhance the reliance on affect. As expected, the inverse relationship was strengthened when time pressure was introduced. Study 2 tested and confirmed the hypothesis that providing information designed to alter the favorability of one's overall affective evaluation of an item (say nuclear power) would systematically change the risk and benefit judgments for that item. Both studies suggest that people seem prone to using an ‘affect heuristic’ which improves judgmental efficiency by deriving both risk and benefit evaluations from a common source—affective reactions to the stimulus item.

Minimizing Mistreatment by Female Adults: The Influence of Gender-Based Social Categories and Personality Differences on Attitudes about Child Sexual Abuse

We investigated the effects of gender-based social categories (i.e., men, women, boys, and girls) on attitudes about child sexual abuse and individual differences in the use of such categories. In four experiments, we systematically varied perpetrators’ sex and victims’ sex. In three investigations, we assessed personality variables potentially related to participants’ use of these social categories. Across these four experiments, we varied perpetrator-victim relationships (teacher-student, neighbors) and victims’ ages. In experiment one, individuals had the least negative attitude about child sexual abuse involving adult female neighbors and eighth grade male neighbors. In experiment two, we replicated this effect with fifth grade victims and demonstrated that attitudes were moderated by individual differences in intolerance of ambiguity. In experiment three, we again replicated the aforementioned effect while (a) extending this finding to teacher-student relationships with eighth grade adolescent victims and (b) demonstrating the need for cognition was a moderator. In experiment four, we again replicated (a) our perpetrator sex/victim sex interactive effect and (b) need for cognition moderation while also demonstrating that these effects were applicable to fifth grade victims. Methodological limitations as well as clinical and policy implications (e.g., attenuating the underreporting incidents of child sexual abuse) are discussed.
