为了解攻击行为儿童大脑两半球的认知活动特点，采用侧视野速示呈现技术，对经“同伴提名量表”筛选的１７名攻击行为儿童（平均年龄８．９７岁）和１６名正常儿童（平均年龄９．０３岁）进行了比较研究。１．在图、字Ｓｔｒｏｏｐ效应实验中，实验组较对照组有显著的右视野Ｓｔｒｏｏｐ效应。２．在格式塔图形辨别实验中，实验组较正常组有较低的左视野图形辨别阈限。另外，两组内左、右视野间均有差异，为左侧低于右侧。结果提示：攻击行为儿童与正常儿童比较，大脑两半球均衡性发展与协同功能较低，显示左半球抗干扰能力较差，右半球完形认知能力较弱。这可能是儿童攻击行为的某些神经心理学基础。

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 exsisted 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 hemisphereperception of configuration in some cognitive processes. The differences may probablybe the neuropsychological bases for the children's aggressive behavior.
