先前使用单词命名任务的研究表明,在痴呆患者中,语义启动仅来自自动传播激活,而不是来自注意力依赖过程。如果这是真的,那么在词汇决策任务中,注意力依赖过程是语义启动效应的主要来源,痴呆患者应该表现出很少或没有启动。为了测试这一预测,三组 16 名受试者(年轻人、正常老年人和阿尔茨海默病患者)接受了单词命名和词汇决策任务。在这两项任务中,都确定了语义启动量(对语义无关词与语义相关词之前的词的响应时间差异)。在这两项任务中,痴呆症患者都比正常组表现出明显更强的语义启动。这一结果反驳了这样一种假设,即痴呆患者中发现的语义启动仅归因于自动过程。
Previous studies using a word-naming task have suggested that in demented patients, semantic priming results only from automatic spreading activation and not from attention-dependent processes. If this is true, then on a lexical-decision task where attention-dependent processes are a major source of the semantic-priming effect, demented patients should show little or no priming. To test this prediction, three groups of 16 subjects (young and normal-old individuals and patients with Alzheimer's disease) were given a Word-Naming and a Lexical-Decision task. In both tasks, the amount of semantic priming (the difference in response time to a word preceded by a semantically unassociated vs. a semantically associated word) was determined. Demented patients showed significantly greater semantic priming than either normal group on both tasks. This result argues against the hypothesis that the semantic priming found in demented patients is due solely to automatic processes.
