Short-term implicit memory was examined for mixed auditory (A) and visual (V) stimuli. In lexical decision, words and nonwords were repeated at lags of 0, 1, 3, and 6 intervening trials, in four prime-target combinations (VV, VA, AV, AA). Same-modality repetition priming showed a lag x lexicality interaction for visual stimuli (nonwords decayed faster), but not for auditory stimuli (longer lasting smooth decay for both words and nonwords). These modality differences suggest that short-term priming has a perceptual locus, with the phonological lexicon maintaining stimuli active longer than the orthographic lexicon and treating pseudowords as potential words. We interpret these differences in terms of the different memory needs of speech recognition and text reading. Weak cross-modality short-term priming was present for words and nonwords, indicating recoding between perceptual forms.
对混合听觉（A）和视觉（V）刺激的短期内隐记忆进行了研究。在词汇判断任务中，单词和非单词在间隔0、1、3和6次中间试验的滞后条件下重复呈现，共有四种启动-目标组合（VV、VA、AV、AA）。同模态重复启动效应在视觉刺激中表现出滞后×词汇性交互作用（非单词衰减更快），但在听觉刺激中未表现出这种作用（单词和非单词的衰减都较为平稳且持续时间更长）。这些模态差异表明，短期启动效应具有感知层面的定位，语音词汇表使刺激保持活跃的时间比正字法词汇表更长，并且将假词视为潜在单词。我们从语音识别和文本阅读的不同记忆需求角度来解释这些差异。单词和非单词存在较弱的跨模态短期启动效应，这表明在感知形式之间存在重新编码。
