长时形态启动是重复启动的一种形式，在重复启动中，一个词的识别是通过事先呈现一个与形态相关的词来启动的。我们使用一种不同的片段完成任务来研究形态启动，在这个任务中，一个单词被短暂地呈现出来，它的一个字母被一个模式掩码取代，受试者试图识别这个掩码所隐藏的字母。在实验1中，研究中的加工水平操作被发现影响自由回忆，但不影响掩蔽片段的完成，这表明后一项任务中的重复启动不是外显记忆过程的结果。随后的实验表明，掩蔽和标准片段的完成都受到形态启动的影响，尽管这种影响不能归因于形态相关词的拼写和语音相似性，但它的大小确实随着拼写相似性的变化而变化。这些结果与连接主义者对形态启动的描述是一致的，其中形态效应来自连接主义者网络的激活动力学，尽管形态关系在这个网络中没有被明确地表示出来。(C)1997年学术出版社。
Long-term morphological priming is a form of repetition priming in which the identification of a word is primed by the prior presentation of a morphologically related word. We investigated morphological priming using a variant of the fragment completion task in which a word is briefly presented with one of its letters replaced by a pattern mask and subjects attempt to identify the letter ''hidden'' by the mask. In Experiment 1 a levels-of-processing manipulation at study was found to affect free recall but not masked fragment completion, suggesting that repetition priming in the latter task is not the result of explicit memory processes. Subsequent experiments revealed that both masked and standard fragment completion are influenced by morphological priming and that, although this effect cannot be attributed to the orthographic and phonological similarity of morphologically related words, it does vary in magnitude as a function of orthographic similarity. These results are consistent with a connectionist account of morphological priming in which morphological effects arise from the activation dynamics of a connectionist network even though morphological relationships are not explicitly represented in this network.
