Performance on two measures of lexical retrieval for 19 left and 13 right brain lesioned children was compared to that of control subjects matched by age, sex, race, and social class. On the Word-Finding Test, left lesioned subjects were significantly slower in response time than left controls when given semantic and visual cues and made more errors when given rhyming cues. On the Rapid Automatized Naming Test, left lesioned subjects were significantly slower than left controls in naming all semantic categories, including colors, numbers, objects, and letters. In contrast, right lesioned subjects responded as quickly as or more quickly than did right controls in all access conditions and in naming semantic categories yet tended to produce more errors than their controls, suggesting a speed-accuracy tradeoff. Children sustaining left brain lesions before 1 year of age appeared to be as impaired as those whose lesions occurred after 1 year of age. Diverse lesion sites within the left hemisphere were associated with increased lexical retrieval latencies.
将19名左脑损伤儿童和13名右脑损伤儿童在两种词汇检索测量中的表现，与按年龄、性别、种族和社会阶层匹配的对照组受试者的表现进行了比较。在单词查找测试中，当给予语义和视觉线索时，左脑损伤受试者的反应时间明显比左脑对照组慢，当给予押韵线索时，犯错更多。在快速自动命名测试中，左脑损伤受试者在命名所有语义类别（包括颜色、数字、物体和字母）时明显比左脑对照组慢。相比之下，右脑损伤受试者在所有检索条件下和命名语义类别时的反应与右脑对照组一样快或更快，但往往比对照组产生更多错误，这表明存在速度与准确性的权衡。1岁前遭受左脑损伤的儿童似乎与1岁后损伤的儿童受损程度相同。左脑半球内不同的损伤部位与词汇检索潜伏期增加有关。
