本研究采用实验设计，考察了言语刺激呈现通道信息的持久性轨迹。24名学生被要求提供672个连续的字母序列进行词/非词分类。这些序列在单词和非单词之间平均分配，每个项目在该系列中以相同或不同的方式呈现两次。重复促进，优势来自第二次演示，是最大的在模态内条件的话（+re反应）和nonwords（-ve反应）。这些条件下的易化从滞后0（4秒）的170 msec下降到滞后63的约40 msec。促进减少了跨通道条件的话，是不存在的跨通道条件的非词。在词/非词分类范式中发现的重复效应的模态特定成分可能归因于非词汇的持久性，与词汇不同，词分类过程的成分。
An experiment was designed to investigate the locus of persistence of information about presentation modality for verbal stimuli. Twenty-four Ss were presented with a continuous series of 672 letter sequences for word/nonword categorization. The sequences were divided equally between words and nonwords, and each item was presented twice in the series, either in the same or in a different modality. Repetition facilitation, the advantage resulting from a second presentation, was greatest in the intramodality conditions for both words (+re responses) and nonwords (−ve responses). Facilitation in these conditions declined from 170 msec at Lag 0 (4 sec) to approximately 40 msec at Lag 63. Facilitation was reduced in the cross-modality condition for words and was absent from the cross-modality condition for nonwords. The modality-specific component of the repetition effect found in the word/nonword categorization paradigm may be attributed to persistence in the nonlexical, as distinct from lexical, component of the word categorization process.
