五个实验探讨了口语句子生成过程中概念和语法编码的范围。在一项在线图片描述任务中，参与者根据一系列移动的图片物体生成各种句子。实验一表明，以复杂短语开头的单句句（例如，狗和风筝在房子上面移动）比以简单短语开头的匹配单句句（例如，狗在风筝和房子上面移动）的启动潜伏期更长。这一发现表明，在言语开始之前，更多的时间用于处理话语的第一个短语，而不是其余的时间。实验2和3，比较单句和双句的生成。实验1的主要效果被复制。然而，数据也表明，在言语开始之前，有一些时间专门用于处理第二分句中的元素。在实验4中，当被试在动作和计时器开始前预览图片时，初始短语复杂性的影响显著降低，表明先前观察到的延迟效应主要反映引理获取。最后，实验5表明，第一个短语内的名词比第一个短语以外的名词的减少幅度更大。我们从这些实验中得出结论，在言语开始之前，对话语的第一个短语的引理获取已经完成，而对第一个短语以外的句子的其余部分的高层次处理已经启动，但尚未完成。(C) 1999 Elsevier Science B.V.版权所有
Five experiments investigate the scope of conceptual and grammatical encoding during spoken sentence production. An online picture description task is employed in which participants generate a variety of sentences in response to an array of moving pictured objects. Experiment I, demonstrates longer onset latencies for single clause sentences beginning with a complex phrase (e.g. The dog and the kite move above the house) than for matched single clause sentences beginning with a simple phrase (e.g. The dog moves above the kite and the house), This finding suggests that more time is dedicated to the processing of the first phrase of an utterance than the remainder prior to speech onset. Experiments 2 and 3, compare the production of single and double clause sentences. The main effect of Experiment 1 is replicated. However, the data also suggest that some time is dedicated to the processing of elements within the second clause prior to speech onset. In Experiment 4, when participants are allowed to preview pictures prior to movement and timer onset the effect of initial phrase complexity is significantly reduced indicating that the latency effects observed previously primarily reflect lemma access. Finally, Experiment 5 demonstrates that this reduction is greater for nouns within the first phrase than for nouns beyond it. We conclude from these experiments that, prior to speech onset, lemma access is completed for the first phrase of an utterance and that high level processing is initiated but not completed for the remainder of a sentence beyond the first phrase.
