Weaker inter- than intramodality long-term priming of words has promoted two hypotheses: (1) separate visual and auditory lexicons and (2) modality dependence of implicit memory. In five experiments, we employed manipulations aimed to minimize study-test asymmetries between the two priming conditions. Activities at visual and auditory study were matched, words were phonologically consistent, and study modality was manipulated between subjects. Equal magnitudes of inter- and intramodality priming were found in experiments with visual and auditory stem completion at test, with visual fragment completion at test, and with visual and auditory perceptual identification at test. A within-subjects experiment yielded the conventional intramodality advantage. The results point to a single amodal lexicon and to modality-independent phonological processing as the basis of implicit word memory.
相较于模态内长期启动，较弱的模态间单词启动引发了两种假说：（1）视觉和听觉词库相互独立，以及（2）内隐记忆的模态依赖性。在五项实验中，我们采用了旨在最小化两种启动条件之间学习-测试不对称性的操作。视觉和听觉学习时的活动相匹配，单词在语音上保持一致，并且学习模态在不同被试间进行操纵。在测试时进行视觉和听觉词干补全、视觉片段补全以及视觉和听觉知觉识别的实验中，发现模态间和模态内启动的程度相同。一项被试内实验产生了传统的模态内优势。结果表明，存在一个单一的非模态词库以及与模态无关的语音加工是内隐单词记忆的基础。
