Abstract

"Minimal brain damage" children and controls matched for age, sex and intelligence were assessed for lateral preference, unimanual motor speed, reaction time to lateralised stimuli and dichotic ear advantage. "Minimal brain damage" children were found to be less extreme and stable in their lateral preferences, slower, and less lateralised in their motor performance. This suggests a deficit of interhemispheric integration, although the groups did not differ in dichotic listening performance, the normal group failing to show the expected ear advantage. "Minimal brain damage" children may be suffering from a partial disconnection syndrome.

摘要

对“轻微脑损伤”儿童以及在年龄、性别和智力方面与之匹配的对照组进行了如下评估:侧化偏好、单手运动速度、对侧化刺激的反应时间以及双耳分听优势。研究发现,“轻微脑损伤”儿童的侧化偏好不那么极端和稳定,运动速度较慢,并且在运动表现上的侧化程度较低。这表明存在半球间整合缺陷,尽管两组在双耳分听表现上没有差异,正常组也未表现出预期的耳优势。“轻微脑损伤”儿童可能患有部分连接中断综合征。
