These experiments were performed to examine the effects of different types of primes across variations in prime set size, prime strength, and prior study in verification and lexical decision tasks. The primes consisted of taxonomic category names, associates, or rhymes that defined either small or large sets of related concepts, and they were either strongly or weakly related to their targets. Targets either were or were not studied prior to the priming task. The results indicated that, for taxonomic primes, shorter decision latencies were obtained when set size was smaller and when the target was studied before the priming task. In contrast, for rhymes, neither set size nor prior study had reliable effects. For all three types of primes, decision latencies were faster for stronger than for weaker prime-to-target relationships. These findings are contrasted with the results of manipulating these variables in episodic tasks such as cued recall, and they are interpreted in the context of a components-of-processing approach.
进行这些实验是为了检验在验证和词汇判断任务中,不同类型的启动刺激在启动刺激集大小、启动刺激强度以及先前学习等变量变化时所产生的影响。启动刺激由分类类别名称、联想词或押韵词组成,它们定义了相关概念的小集合或大集合,并且与目标词的关联程度有强有弱。在启动任务之前,目标词要么被学习过,要么没有被学习过。结果表明,对于分类启动刺激,当集合大小较小时以及目标词在启动任务之前被学习过时,决策潜伏期较短。相比之下,对于押韵词,集合大小和先前学习都没有可靠的影响。对于所有三种类型的启动刺激,启动刺激与目标词的关系较强时的决策潜伏期比关系较弱时更快。这些发现与在诸如线索回忆等情景任务中操纵这些变量的结果形成对比,并在加工成分方法的背景下进行了解释。
