Abstract

The effects of lexical meaning and lexical familiarity on auditory deviance detection were investigated by presenting oddball sequences of words, while participants ignored the stimuli. Stimulus sequences were composed of words that were varied in word class (nouns vs. functions words) and frequency of language use (high vs. low frequency) in a factorial design with the roles of frequently presented stimuli (Standards) and infrequently presented ones (Deviants) were fully crossed. Deviants elicited the Mismatch Negativity component of the event-related brain potential. Modulating effects of lexical meaning were obtained, revealing processing advantages for denotationally meaningful items. However, no effect of word frequency was observed. These results demonstrate that an apparently low-level function, such as auditory deviance detection utilizes information from the mental lexicon even for task-irrelevant stimuli.

摘要

通过呈现单词的分听序列，研究了词汇意义和词汇熟悉度对听觉偏离检测的影响，而参与者忽略了这些刺激。刺激序列由在词类（名词与功能词）和语言使用频率（高与低）上变化的单词组成，在一个完全交叉的因子设计中，经常呈现的刺激（标准）和不常呈现的刺激（偏离）的作用被充分交叉。偏离引发了事件相关脑电位的不匹配负波成分。获得了词汇意义的调节效应，揭示了具有指称意义的项目具有处理优势。然而，没有观察到词频的影响。这些结果表明，即使对于任务无关的刺激，一个明显的低水平功能，如听觉偏离检测，也利用了心理词汇的信息。
