Neighborhood Disadvantage, Parent–Child Conflict, Neighborhood Peer Relationships, and Early Antisocial Behavior Problem Trajectories

  This study examined relations among neighborhood disadvantage, parent–child conflict, deviant peer involvement in the neighborhood, and early-starting antisocial trajectories. Antisocial group patterns were identified in 218 low-income boys followed from ages 5 to 11, and neighborhood and family variables were evaluated as predictors in early and middle childhood. Four trajectory groups emerged: one increasing pattern that corresponded with developmental theories of early-starting antisocial behavior; one with initially high and decreasing problems over time; and two low antisocial groups. Parent–child conflict and neighborhood disadvantage were significantly associated with trajectory patterns, with youth in the 2 higher antisocial behavior groups characterized by more neighborhood problems and parent–child conflict than other groups. The results suggest that in early childhood, neighborhood disadvantage and family conflict place children at risk for early-starting trajectories, and that involvement with deviant peers in the neighborhood takes on an increasingly important role in patterns of antisocial behavior over middle childhood.     

Operant discrimination training to establish praise as a reinforcer

Social deficits are a hallmark feature of autism spectrum disorder (ASD). Consequently, socially mediated consequences (i.e., praise) may not function as reinforcers for individuals with ASD. Given the frequency in which praise is used as a programmed consequence in empirical research and in clinical practice, it is necessary to explore procedures that could condition praise to function as reinforcers. Operant discrimination training has emerged as a potential procedure to condition stimuli to acquire reinforcing properties. This study aimed to utilize the operant discrimination training procedure to condition a praise statement to function as a reinforcer. Four children diagnosed with ASD participated in the study. A nonconcurrent multiple baseline design across participants was used to evaluate this emerging pairing procedure. Findings suggest that immediate effects were observed across all participants, but responding did not maintain, suggesting that reinforcing value of the praise statement diminished.     

Children discard a resource to avoid inequity

Elucidating how inequity aversion (a tendency to dislike and correct unequal outcomes) functions as one develops is important to understanding more complex fairness considerations in adulthood. Although previous research has demonstrated that adults and children reduce inequity, it is unclear if people are actually responding negatively to inequity or if people dislike others getting more than them (motivated by social comparison) and like to share maximal resources, especially with those who have few resources (motivated by social welfare preferences). In order to evaluate if children are truly averse to inequity, we had 3- to 8-year-old children distribute resources to 3rd parties and found that 6- to 8-year-old children would rather throw a resource in the trash than distribute unequally, suggesting that concerns with equity can trump concerns with maximal sharing. We also demonstrated that children's reactions were not based on wanting to avoid upsetting the recipients or based on a preference for visual symmetry and that children will even throw away a resource that could have gone to themselves in order to avoid inequity. These results demonstrate the existence of inequity aversion in children, provide a new method for studying inequity aversion specifically, and suggest the need for new models to explain why inequity aversion may have evolved.     

Differential Susceptibility Effects: The Interaction of Negative Emotionality and Sibling Relationship Quality on Childhood Internalizing Problems and Social Skills

Whereas socialization influences in early childhood have been linked to children's emerging internalizing problems and prosocial behavior, relatively few studies have examined how NE might moderate such associations in both advantageous and maladaptive ways. Furthermore, more research is needed to evaluate the impact of sibling relationships as an influential socialization influence on these child outcomes. In the current study we examined how NE might differentially moderate the associations between quality of relationships with siblings and both internalizing problems and social skills at school entry. NE moderated the effects of positive and destructive sibling relationship quality on child internalizing problems. Specifically, for boys high on NE, more positive sibling relationship quality predicted fewer internalizing problems, but more destructive sibling conflict predicted more internalizing problems. NE also moderated the effects of destructive sibling conflict on child social skills. For boys high on NE, destructive sibling conflict predicted fewer social skills. Boys high on NE appear to show greater susceptibility to the effects of sibling socialization on child outcomes, relative to boys low on NE. The implications of these interactions are discussed with respect to differential susceptibility theory.     

Banking on brains: Insights of brain donor relatives and friends from an experiential perspective

Brain donation is critical to understand the pathological causes of neurodegenerative diseases. Increasing levels of donation requires an understanding of those factors that both encourage and deter donation. At present, there are few studies of how people understand, feel and decide about brain donation for scientific research. This qualitative experiential study contributes to the growing literature on brain donation through its specific focus on how the donation process is experienced from the perspectives of family members and friends. Nineteen semi-structured interviews were analysed using a phenomenologically informed thematic analysis. Four themes were derived from the analysis, three of which are described in detail: Making the decision to donate; a personal perspective on the donation process; the significance of the brain; beliefs about brain donation. In particular, the thematic analysis highlights the variation of individual decision making and the emotions and reasons underpinning such decisions. Key conclusions include the importance of integrated practice amongst relevant healthcare professionals as well as the need for supportive and informed communication. Also, in light of the finding that the brain assumed no special significance for most participants, the value of the distinction between brain donation for research purposes and organ transplantation is questioned.     

Attending to simple auditory and visual signals

Rutgers-The State University, New Brunswick, New Jersey 08903 Is the quality of information obtained from simple auditory and visual signals diminished when both modalities must be attended to simultaneously? This question was investigated in an experiment in which subjects made forced-choice judgments of the location of simple light and tone signals presented in focused- and divided-attention conditions. The data are compared with the predictions of a model that describes the largest performance decrement to be expected in the divided-attention condition on the basis of nonattentional factors. The results of this comparison suggest that the difference in performance between focused- and dividedattention conditions is attributable solely to the increased opportunity to confuse signal with noise as the number of modalities is increased. Thus, there appears to be no evidence that dividing attention between modalities affects the quality of the stimulus representations of individual light and tone signals.     

Positive development in emerging adulthood

Positive functioning in the developmental period of emerging adulthood has received little investigation. The current study investigated components of positive development using confirmatory factor analysis of Australian Temperament Project data collected from 1,158 young adults aged 19–20 years. Positive development constructs that have been theoretically conceptualised were examined to test core concepts. Five first‐order constructs were identified in this sample: Civic Action and Engagement, Social Competence, Life Satisfaction, Trust and Tolerance of Others, and Trust in Authorities and Organisations. A second‐order positive development factor defined by these constructs provided good fit for the data. This model of positive development in emerging adulthood can provide an outcome measure that can then be used to investigate the developmental processes and pathways involved.
