对词汇加工各个阶段的时间进程的研究表明，语音代码提取的大脑激活可以是早期的，也可以是晚期的。差异发现的基础尚不清楚，但与音段音位相关的因素似乎是其中的一部分。本研究的目的是确定辅音类型是否影响音位编码。向本科生展示了常见和熟悉物体的图片来命名。每个图片标签有一个初始的液体（/l/，//）或一个停止（/B/，/d/）辅音。图片命名的准确性是高的，可比的两个刺激集。然而，以液体开头的单词引起的N2 ERP反应比最初停止的单词大。聚类排列分析表明，在图片启动后293 ms和371 ms之间，两组刺激中的单词引起的ERP反应不同。这些发现表明，语音代码提取的发病较晚。它们对分段语音学和/或运动规划和言语执行有影响。
Investigations of the time course of various stages of lexical processing have indicated either early or late onset of brain activation for phonological code retrieval. The basis of the differential findings is unclear, but factors related to segmental phonology appear to be part of it. The purpose of the present study was to determine whether phonological encoding is influenced by consonant type. Undergraduate students were presented pictures of common and familiar objects to name. Each picture label had an initial liquid (/l/, /ɹ /) or a stop (/b/, /d/) consonant. Accuracy of picture naming was high and comparable for the two stimulus sets. However, words beginning with liquids elicited larger N2 ERP responses than did those with initial stops. Cluster permutation analysis indicated that the ERP responses elicited by words in the two stimulus sets differed between 293 ms and 371 ms post picture onset. These findings point to a late onset of phonological code retrieval. They have implications for segmental phonology and/or motor planning and execution of speech.
