Abstract
The comparative study between 17 aggressive behavior children (average age 8.97) who were selected by the “Peer-Nomination Inventory” and 16 normal children (average age 9.03) aimed at understanding the cognitive characteristics of aggressive subjects and their cerebral hemisphere integrative abilities. The cognitive stimuli were presented tachistoscopically to the left and right visual fields. (1) In the experiment of Stroop Effect, the aggressive group had high right-visual figure-Chinese character Stroop effect compared with the controls, while within groups, neither aggressive subjects nor controls had significant left vs. right-visual field Stroop effect. (2) In the Gestalt Figure Perception experiment, the aggressive boys had significantly low level of left-visual discriminative limen, and there also existed left vs. right-visual discrimination differences within both groups. The results suggested that aggressive children were inferior to the normal group in cerebral hemisphere balanced development and brain cooperative or integrative functions, presented in this study, as insufficient left hemisphere ability against interferences and inadequate right hemisphere perception of configuration in some cognitive processes. The differences may probably be the neuropsychological bases for the children’s aggressive behavior.
