Abstract

Maternal ratings of overt and covert forms of aggression were collected for two samples of children ranging in age from 2 through 12 years. It was hypothesized that longitudinal analyses would show the slope scores for these two forms of aggression to be quite different from each other. The data were consistent with this hypothesis. An effort was made to find alternative explanations for the negative slope for overt antisocial behavior. Alternatively, it was hypothesized that the more extreme cases would not show this negative slope. It was also hypothesized that careful examination of intraindividual curves would identify a significant number of individuals growing from normal to clinical levels of overt antisocial behavior. The findings led to the rejection of both alternative hypotheses. It was hypothesized that overt and covert scores would correlate significantly for first grade boys. It was also assumed that both covert and overt scores would show moderate stability over the 5-year interval. The findings were consistent with both of these hypotheses.
