Repetition priming refers to the facilitation in the visual identification of a stimulus produced by a recent encounter with that stimulus. In the paradigm used here, subjects performed a naming task in which a sequence of primes was presented; then they performed a tachistoscopic identification task in which the stimuli that were presented varied in their similarity to the primes. The results indicated that repetition priming facilitated the identification of repeated words and pronounceable nonwords that were similar, but not identical, to the recently encountered primes. Moreover, the number of presentations of the primes influenced the amount of facilitation for repeated words but, in contrast to previous findings, had no effect on the amount of facilitation for repeated nonwords or similar words and nonwords. The results are interpreted within a connectionist model of visual word identification.
重复启动效应是指最近接触某一刺激而促进对该刺激的视觉识别。在本文所使用的范式中，受试者执行一项命名任务，在该任务中会呈现一系列启动刺激；然后他们执行一项速示识别任务，在该任务中呈现的刺激与启动刺激的相似程度各不相同。结果表明，重复启动效应促进了对与最近遇到的启动刺激相似但不完全相同的重复单词和可发音非单词的识别。此外，启动刺激的呈现次数影响了对重复单词的促进程度，但与先前的研究结果相反，对重复非单词或相似单词和非单词的促进程度没有影响。这些结果在视觉单词识别的联结主义模型中得到了解释。
