The role of internal inhibition and the frontal lobes in child development

The theory that children show a predominance of excitation over internal inhibition and that this is due to inadequate development of the frontal lobes is explored and extended. Experimental results show that children resemble leucotomised monkeys in their difficulty in overcoming an initial preference in discrimination tasks.     

Race,Gender, and Perceptions of Peer Delinquency: A Within-Subject Analysis

ABSTRACT

We generated a within-subject analysis that assessed whether changes in delinquency from the same youth were associated with changes in the degree to which the youth perceived the delinquency of their peers across three waves of data. We hypothesized that the effect of within-person changes in perceptions of peer delinquency on changes in delinquency across time should be greatest among young black males. The results revealed that a within-person change in the youths’ perceptions that their peers were engaging in greater delinquency increased offending across time. They also showed that young black males were more likely than young white males and young black and white females to increase their level of delinquency, within-person and across time, when they perceived an increase in their peers’ levels of delinquency. We conclude that scholars may generate deeper theoretical insights and policies that are more efficacious when they reveal the causes of crime that are universal and those that uniquely affect a specific group.
