Abstract

Broca's aphasics and normal control subjects performed an auditory lexical decision task with stimulus pairs containing ambiguous (semantically-related) or unambiguous (unrelated) words as primes. Broca's aphasics, though having considerably longer latencies, produced a pattern of results similar to normal subjects; namely, faster reaction times for target words preceded by semantically related than unrelated words (i.e., semantic priming). These results do not support the hypothesis of BLUMSTEIN and colleagues that Broca's aphasics show a selective impairment in automatic processing associated with lexical access.

摘要

布罗卡失语症患者和正常对照组受试者进行了一项听觉词汇判断任务，刺激对包含有歧义（语义相关）或明确（不相关）的单词作为启动词。布罗卡失语症患者虽然潜伏期长得多，但产生的结果模式与正常受试者相似；也就是说，与语义不相关的单词相比，由语义相关的单词作为启动词时，目标单词的反应时间更快（即语义启动）。这些结果不支持布卢姆斯坦及其同事的假设，即布罗卡失语症患者在与词汇通达相关的自动加工过程中表现出选择性损伤。
