Adolescent Friendship as a Dynamic System: Entropy and Deviance in the Etiology and Course of Male Antisocial Behavior

A dynamic systems framework was applied to understand the influence of friendship on antisocial behavior from childhood (age 9-10) through adulthood (age 24-25) for Oregon Youth Study males (N = 206). Boys were videotaped interacting with a friend at ages 14, 16, and 18, and deviant content and interpersonal processes were independently coded. Conditional dyadic interpersonal processes were studied as a communication system and summarized by an index of information entropy (F. Attneave, 1959). High entropy scores represent disorganized, unpredictable patterns of interaction, whereas low entropy scores reflect an organized dialogue. Conversations of early-onset antisocial boys and their best friends were less organized and included more deviant content than those of well-adjusted controls. Prediction analyses, however, revealed an interaction between entropy and deviant talk. Consistent with expectation, males with well-organized interactions (i.e., low entropy) but elevated levels of deviant content were most likely to continue antisocial behavior into adulthood. Findings suggest that individual risk for maladaptation may be amplified by early adolescent friendship dynamics organized around deviance.     

Deviant Peer Affiliation and Problem Behavior: A Test of Genetic and Environmental Influences

This study uses a multitrait, multimethod (MTMM) approach to investigate the genetic and environmental etiologies of childhood deviant peer affiliation (DPA) and problem behavior (PROB). The variability of genetic and environmental estimates by agent and method is also examined. A total of 77 monozygotic and 72 dizygotic twin pairs and each twin's close friend were assessed. The informants included parents, teachers, and twins, and the methods involved questionnaire reports and coder ratings of videotaped dyadic interactions between each twin and their close friend. Twin intraclass correlations and univariate models attributed DPA and PROB to genetic, and shared and nonshared environmental effects. Parameter estimates differed by rater and method, however. Results accentuate the imperative to attend to method effects inherent in MTMM behavioral geneticresearch.

The heterogeneity of picture-supported narratives in Alzheimer's disease

This study describes discourse patterns produced by 46 Alzheimer disease (AD) patients and 53 normal elderly subjects in two picture-supported narratives. Nine measures derived from a cognitive model of discourse processing were obtained and submitted to cluster analysis. Results indicate that discourse patterns elicited from both stimuli were heterogeneous. Further, they fail to clearly differentiate between normal aging and AD in half of the AD patients. Discourse patterns are examined in light of various sources of heterogeneity including severity of cognitive impairment, subject characteristics, and task demands. The usefulness of discourse as a diagnostic and therapeutic tool is discussed.

Integrated Schooling and Religious Tolerance in Northern Ireland

The design of educational institutions has long been seen as a key element in determining social divisions. This article examines the long-term impact of separate and integrated education on relations between the two religious communities (Catholics and Protestants) in Northern Ireland. Using a large-scale survey, the results suggest that in comparison to their previously separate counterparts, individuals who attended an integrated school are more likely to be understanding and respectful of the culture and traditions of others. The finding holds even after a range of background characteristics are taken into account. The results have implications for the role of segregated educational institutions in ameliorating religious, ethnic or racial division in other post-conflict societies. The Northern Ireland evidence suggests that a segregated school system rather than ameliorating intolerance and division may end up exacerbating and reinforcing it.     

The Role of Racial Discrimination in the Economic Value of Education Among Urban,Low-Income Latina/o Youth: Ethnic Identity and Gender as Moderators

The present study used resilience theory to explore relationships among perceived racial discrimination, ethnic identity, gender, and economic value of education (EVE) among urban, low‐income, Latina/o youth. It was expected that racial discrimination would predict poorer perceptions of the EVE among Latina/o adolescents. Ethnic identity was hypothesized to buffer the negative effect of racial discrimination on Latina/o students’ EVE. The participants in this study were 396 urban, low‐income Latina/o high school students from a large, Midwestern city who completed surveys in both 9th‐ and 10th‐grade. Structural equation modeling was used to test the relationships among racial discrimination, ethnic identity, and EVE. Results supported a protective model of resilience. Specifically, ethnic identity served as a protective factor by buffering the negative effect of perceived racial discrimination on EVE for male participants. The present study is the first to examine ethnic identity as a buffer of racial discrimination on EVE among Latina/o high school students. Future directions and implications are discussed.     

Attachment in Adolescence and Borderline Personality Disorder

Borderline personality disorder (BPD) has been conceptualized as a constellation of symptoms related to problems in self-functioning, emotion regulation, and interpersonal relationships. Its etiology has been connected to individuals’ early childhood environment, caregiving relationships, and traumatic life events. Recent literature has noted the potential presence of BPD beginning in adolescence, or even earlier in childhood. Attachment theory offers a lens for understanding the symptoms of borderline personality disorder and identifying potential aspects of treatment that may be specifically valuable for adolescent patients. Adolescence marks a time when the attachment system has increased relevance due to the importance of identity formation, peer relationships, body representations and the development of autonomy at this time, in the face of physical changes and academic challenges. This article will summarize research on attachment, body representations, personality disorders, and features of development in adolescence, in order to enhance clinical understanding of patients who presenting with these types of difficulties.     

Dangerous Enough: Moderating Racial Bias with Contextual Threat Cues

Research shows that participants shoot armed Blacks more frequently and quickly than armed Whites, but make don't-shoot responses more frequently and quickly for unarmed Whites than unarmed Blacks. We argue that this bias reflects the perception of threat — specifically, threat associated with Black males. Other danger cues (not just race) may create a similar predisposition to shoot, and if these cues promote shooting when the target is White, they should attenuate racial bias. We embedded targets in threatening and safe backgrounds. Racial bias was evident in safe contexts but disappeared when context signaled danger, and this reduction was largely due to an increased tendency to shoot White targets.
