为了进一步了解视觉注意习惯化行为与脑功能障碍的关系 ,对79例智能发育异常的2～36个月婴幼儿进行视觉注意习惯化测试。结果显示 :异常儿对6次重复刺激的注视时间非常接近 ,不象正常儿那样有明显逐步下降规律 ;异常儿对1次新鲜图象刺激的注视时间增幅很小 ,不象正常儿那样有一个十分明显的增加高峰 ;异常儿与正常儿的应答降低率和应答恢复率有十分显著的差别。提示视觉注意习惯化行为能够较客观地反映婴幼儿脑功能发育程度 ,并能区分发育正常与异常的小儿 In order to further understand the relationship between visual attention to habitual behavior and brain dysfunction, 79 cases of preschool children with mental retardation between 2 and 36 months were examined with visual attention. The results showed that: abnormal children on the 6 repeated stimulation of the fixation time is very close, not as normal as there is a clear gradual decline in the rules; abnormal children on a fresh image stimulation of gaze time increase is small, not as normal as there is a Very significant increase in the peak; abnormal children and normal children’s response to reduce the rate of response and recovery rate there is a very significant difference. Hints Visual attention Habitualized behavior can more objectively reflect the degree of brain development in infants and young children, and can distinguish between normal and abnormal development of children
