STUDIES OF CEREBRAL HEMISPHERE COGNITIVE CHARACTERISTICS IN CHILDREN OF AGGRESSIVE BEHAVIOR
攻击行为儿童大脑半球某些认知特点的研究

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 aggressivesubjects and their cerebral hemisphere integrative abilities. The cognitive stimuli werepresented tachistoscopically to the left and right visual fields. 1. In the experiment ofStroop Effect the aggressive group had high right--visual figure--Chinese characterStroop effect compared with the controls, while within groups, neither aggressivesubjects nor controls had significant left vs. right--visual field Stroop effect. 2. In theGestalt Figure Perception experiment, the aggressive boys had significantly low levelof left-visual discriminative limen, and there also exsisted left vs. right--visualdiscrimination differences within both groups. The results suggested that aggressivechildren were inferior to the normal group in cerebral hemisphere balanceddevelopment and brain cooperative or integrative functions, presented in this study, asinsufficient left hemisphere ability against interferences and inadequate right hemisphereperception of configuration in some cognitive processes. The differences may probablybe the neuropsychological bases for the children's aggressive behavior.
