Age differences in item manipulation span: the case of letter-number sequencing

The authors report 2 experiments in which they examined age differences in working memory tasks involving complex item manipulation (i.e., letter-number sequencing). In Experiment 1, age differences on tasks involving item manipulation were not greater than age differences on tasks requiring recall of items in the order in which they appeared, suggesting that older adults do not have difficulty with item manipulation per se. In Experiment 2, slower presentation rates increased age differences in item manipulation spans, although age differences at the fastest rate may be attributed to differences in strategy use. In both experiments, age differences were largest when participants were most likely to be remembering familiar sequences, suggesting that older adults may have difficulties dampening the representations of such sequences once they are activated.

Peer network drinking predicts increased alcohol use from adolescence to early adulthood after controlling for genetic and shared environmental selection

Research consistently links adolescents' and young adults' drinking with their peers' alcohol intake. In interpreting this correlation, 2 essential questions are often overlooked. First, which peers are more important, best friends or broader social networks? Second, do peers cause increased drinking, or do young people select friends whose drinking habits match their own? The present study combines social network analyses with family (twin and sibling) designs to answer these questions via data from the National Longitudinal Study of Adolescent Health. Analysis of peer nomination data from 134 schools (n = 82,629) and 1,846 twin and sibling pairs shows that peer network substance use predicts changes in drinking from adolescence into young adult life even after controlling for genetic and shared environmental selection, as well as best friend substance use. This effect was particularly strong for high-intensity friendships. Although the peer-adolescent drinking correlation is partially explained by selection, the present finding offers powerful evidence that peers also cause increased drinking.

Emotional response to musical repetition

Two experiments examined the effects of repetition on listeners' emotional response to music. Listeners heard recordings of orchestral music that contained a large section repeated twice. The music had a symmetric phrase structure (same-length phrases) in Experiment 1 and an asymmetric phrase structure (different-length phrases) in Experiment 2, hypothesized to alter the predictability of sensitivity to musical repetition. Continuous measures of arousal and valence were compared across music that contained identical repetition, variation (related), or contrasting (unrelated) structure. Listeners' emotional arousal ratings differed most for contrasting music, moderately for variations, and least for repeating musical segments. A computational model for the detection of repeated musical segments was applied to the listeners' emotional responses. The model detected the locations of phrase boundaries from the emotional responses better than from performed tempo or physical intensity in both experiments. These findings indicate the importance of repetition in listeners' emotional response to music and in the perceptual segmentation of musical structure.     

Factors Associated with Perceived Cognitive Problems in Children and Adolescents with Congenital Heart Disease

The objective of the present study was to assess demographic and disease-specific factors associated with perceived cognitive problems in children and adolescents with heart disease. 246 children with congenital heart disease ages 8–18 years and their parents completed the Cognitive Problems Scale of the Pediatric Quality of Life Inventory Cardiac Module. The 5-item Cognitive Problems Scale assesses school-related cognitive problems including attention and memory from the perspective of the child and parent. Multiple linear regression analysis was conducted with demographic variables and disease-specific factors entered as independent variables and perceived cognitive problems as the dependent variable. Socioeconomic status (SES) and cardiac disease severity were significantly associated with parent proxy-reported cognitive problems (p < .05). None of the demographic or disease-specific variables were significantly associated with child self-reported cognitive problems. In conclusion, our data suggest that assessment of perceived cognitive problems in children and adolescents with greater disease severity and from lower SES homes may facilitate early identification of children who need formal evaluation and interventions to address cognitive impairments.     

Episodic future thought: Contributions from working memory

The ability to imagine hypothetical events in one’s personal future is thought to involve a number of constituent cognitive processes. We investigated the extent to which individual differences in working memory capacity contribute to facets of episodic future thought. College students completed simple and complex measures of working memory and were cued to recall autobiographical memories and imagine future autobiographical events consisting of varying levels of specificity (i.e., ranging from generic to increasingly specific and detailed events). Consistent with previous findings, future thought was related to analogous measures of autobiographical memory, likely reflecting overlapping cognitive factors supporting both past and future thought. Additionally, after controlling for autobiographical memory, residual working memory variance independently predicted future episodic specificity. We suggest that when imagining future events, working memory contributes to the construction of a single, coherent, future event depiction, but not to the retrieval or elaboration of event details.     

Effects of Multiple Maternal Relationship Transitions on Offspring Antisocial Behavior in Childhood and Adolescence: A Cousin-Comparison Analysis

Previous studies of the association between multiple parental relationship transitions (i.e., when a parent begins or terminates an intimate relationship involving cohabitation) and offspring antisocial behavior have varied in their efforts to rule out confounding influences, such as parental antisocial behavior and low income. They also have been limited in the representativeness of their samples. Thus, it remains unclear to what degree parents’ multiple relationship transitions have independent effects on children’s antisocial behavior. Analyses were conducted using data on 8,652 6–9-year-old, 6,911 10–13-year-old, and 6,495 14–17-year-old offspring of a nationally representative sample of U.S. women. Cousin-comparisons were used in combination with statistical covariates to evaluate the associations between maternal relationship transitions and offspring antisocial behavior in childhood and adolescence. Cousin-comparisons suggested that associations between maternal relationship transitions and antisocial behavior in childhood and early adolescence are largely explained by confounding factors. In contrast, the associations between maternal relationship transitions and offspring delinquency in late adolescence were robust to measured and unmeasured confounds. The present findings suggest that interventions aimed at reducing exposure to parental relationship transitions or addressing the psychosocial consequences of exposure to parental relationship transitions could reduce risk for offspring delinquency in late adolescence.     

Evaluating Agency and Responsibility in Gendered Violence: African American Youth Talk About Violence and Hip Hop

The results of this study provide insights into the ways that African American adolescents think about gendered interpersonal violence. African American high school students were invited to discuss images and incidents from contemporary urban music culture (events based on incidents with famous hip hop figures and lyrics from rap music) in a focus group format. We explored how African American youth perceived and responded to examples of gendered violence portrayed in vignettes and musical lyrics. The main analyses focus on the question of how youths’ perceptions of hip hop images, hypothetical stories, and lyrics were linked to their views of “normative” gender interactions and interpersonal relationships for their racial group.
