PURPOSE
The authors examined the involvement of 2 speech motor programming processes identified by S. T. Klapp (1995, 2003) during the articulation of utterances differing in syllable and sequence complexity. According to S. T. Klapp, 1 process, INT, resolves the demands of the programmed unit, whereas a second process, SEQ, oversees the serial order demands of longer sequences.
METHOD
A modified reaction time paradigm was used to assess INT and SEQ demands. Specifically, syllable complexity was dependent on syllable structure, whereas sequence complexity involved either repeated or unique syllabi within an utterance.
RESULTS
INT execution was slowed when articulating single syllables in the form CCCV compared to simpler CV syllables. Planning unique syllables within a multisyllabic utterance rather than repetitions of the same syllable slowed INT but not SEQ.
CONCLUSIONS
The INT speech motor programming process, important for mental syllabary access, is sensitive to changes in both syllable structure and the number of unique syllables in an utterance.
目的
作者研究了S. T. 克拉普（1995年、2003年）所确定的两种言语运动编程过程在发音音节和序列复杂度不同的话语时的参与情况。根据S. T. 克拉普的研究，一种过程INT解决编程单元的需求，而另一种过程SEQ监督较长序列的顺序需求。
方法
使用一种经过修改的反应时范式来评估INT和SEQ的需求。具体而言，音节复杂度取决于音节结构，而序列复杂度涉及话语中重复或独特的音节。
结果
与更简单的CV音节相比，以CCCV形式发音单音节时，INT的执行速度会减慢。在多音节话语中规划独特的音节而非重复相同的音节会减慢INT，但不会减慢SEQ。
结论
INT言语运动编程过程对于心理音节表访问很重要，它对音节结构的变化以及话语中独特音节的数量都很敏感。
