The interrelationships among aggressive needs, anticipation of punishment, and overt aggressive behavior in 29 lower-class boys were investigated in this study. Three hypotheses were tested: 1) among lower class boys, those having a relatively great amount of fantasy aggressive needs indulge in more overt aggressive behavior than those who have relatively few aggressive fantasy needs; 2) Ss whose TAT stories included a great deal of punishment press relative to the number of their aggressive needs demonstrate less overt aggression than Ss whose ratios of punishment press to aggressive needs are low; and 3) Those with low punishment press/aggressive fantasy ratio show more aggression in their behavior than those with high P/A ratio. All three hypotheses were supported by the data. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
