根据 Levelt、Roelofs 和 Meyer (1999) 的说法，说话者会按顺序生成一个单词的连续音节的语音和语音表示，并且只有在完全计划好至少一个完整的语音单词后才开始说话。因此，长词的言语起始潜伏期应该比短词的言语起始潜伏期更长。我们在四个实验中测试了这一预测，在这些实验中，荷兰参与者用单音节或双音节名称对物体进行命名或分类。当在单独的块中测试具有长名称和短名称的对象时，实验 I 对生产延迟产生了长度影响，但当它们混合时则没有。实验2表明，长度效应并不是由于物体识别难易程度的差异造成的。实验 3 使用参与者内部设计复制了实验 I 的结果。在实验4中，长目标词和短目标词出现在短语上下文中。除了语音开始延迟之外，我们还获得了目标对象的观看时间，这已被证明取决于规划目标名称的形式所需的时间。我们发现两个因变量的字长效应，但只有当具有短名称和长名称的对象出现在单独的块中时。我们认为，在纯块和混合块中，说话者使用不同的响应期限，他们试图通过在言语开始之前生成单词的一个音节或所有音节的运动程序来满足这些期限。使用 WEAVER++ 的计算机模拟支持了这一观点。 (C) 2002 年爱思唯尔科学（美国）。版权所有。
According to Levelt, Roelofs, and Meyer (1999) speakers generate the phonological and phonetic representations of successive syllables of a word in sequence and only begin to speak after having fully planned at least one complete phonological word. Therefore, speech onset latencies should be longer for long than for short words. We tested this prediction in four experiments in which Dutch participants named or categorized objects with monosyllabic or disyllabic names. Experiment I yielded a length effect on production latencies when objects with long and short names were tested in separate blocks, but not when they were mixed. Experiment 2 showed that the length effect was not due to a difference in the ease of object recognition. Experiment 3 replicated the results of Experiment I using a within-participants design. In Experiment 4, the long and short target words appeared in a phrasal context. In addition to the speech onset latencies, we obtained the viewing times for the target objects, which have been shown to depend on the time necessary to plan the form of the target names. We found word length effects for both dependent variables, but only when objects with short and long names were presented in separate blocks. We argue that in pure and mixed blocks speakers used different response deadlines, which they tried to meet by either generating the motor programs for one syllable or for all syllables of the word before speech onset. Computer simulations using WEAVER++ support this view. (C) 2002 Elsevier Science (USA). All rights reserved.
