Children at play: the role of peers in understanding the effects of child care

Although the studies of the National Institute of Child Health and Human Development (NICHD) Early Child Care Research Network (this issue) and of Watamura, Donzella, Alwin, and Gunnar (this issue) identify the potential of child care to affect children's adjustment, how these effects are produced remains unclear. In this commentary, it is argued that there is a need to expand child care research by considering one of the most important, but unrecognized, contributors to child care effects-peers. Research is reviewed that suggests that children's interactions in same-sex peer groups at child care affect their short- and long-term adjustment. We consider how research on early peer influences can inform the findings of the NICHD Early Child Care Research Network and Watamura et al. studies, aswell as contribute to the next generation of child care research.

A matched cohort comparison of a criminal justice system's response to child sexual abuse: a profile of perpetrators

OBJECTIVE: This study was undertaken to examine whether alleged child sexual abuse perpetrators are handled differently by the courts than other alleged felony perpetrators. Comparisons were made from the time of prosecutorial case acceptance through prosecution to sentencing, with emphasis on judicial and prosecutorial decision-making and plea-bargaining. METHOD: Data were retrospectively abstracted on the entire defendant population of cases of sexual abuse of children and adolescents (ages 2-17) over a 5-year period. Using a case-flow analysis, comparisons were made between a child sexual abuse cohort and a cohort of matched felony cases from a single jurisdiction. RESULTS: Three important findings emerged. First, compared to other felons, abuse perpetrators were employed, had been married, were mostly European American, and were older than 30 years of age. Second, in the abuse cohort, as many as 14% had a previous sexual or violent record compared to 2% in the comparison group. Third, similar percentages of perpetrators in both groups were released on their own recognizance, had the charges against them dropped, and were found guilty. As well, no differences between groups were found in the proportion of individuals sentenced to jail, probation, counseling, or work release. CONCLUSIONS: Although the treatment of perpetrators of child sexual abuse was similar to the treatment of perpetrators of other felonies, the profile of the child abuse perpetrator was quite different. Knowledge about this profile may impact prosecution or treatment and recidivism rates, to the extent that recidivism is related to characteristics of the abuse perpetrator.

Protection from extinction

The effect of the presence of a conditioned inhibitor on extinction of excitatory conditioning was studied in one magazine approach and three autoshaping experiments using rats and pigeons. In each case, the presence of an inhibitor reduced responding to an exciter during extinction but allowed substantial recovery of responding to that exciter when subsequently tested separately. Control stimuli with a history of being irrelevant to reinforcement or being nonreinforced had less of a protective effect. This constitutes a clear demonstration of protection from extinction, a phenomenon of substantial theoretical and applied importance.
