Abstract

Although lexical competition has been ubiquitously observed in spoken word recognition, less has been known about whether the lexical competitors interfere with the recognition of the target and how lexical interference is resolved. The present study examined whether lexical competitors overlapping in output with the target would interfere with its recognition, and tested an underestimated hypothesis that the domain-general inhibitory control contributes to the resolution of lexical interference. Specifically, in this study, a Visual World Paradigm was used to access the temporal dynamics of lexical activations when participants were moving the mouse cursor to the written word form of the spoken word they heard. By using Chinese characters, the orthographic similarity between the lexical competitor and target was manipulated independently of their phonological overlap. The results demonstrated that behavioral performance in the similar condition was poorer compared to that in the control condition, and that individuals with better inhibitory control (having smaller Stroop interference effect) exhibited weaker activation of orthographic competitors (mouse trajectories less attracted by the orthographic competitors). The implications of these findings for our understanding of lexical interference and its resolution in spoken word recognition were discussed.

摘要

虽然词汇竞争在口语识别中无处不在，但对于词汇竞争是否干扰目标的识别以及如何解决词汇干扰的问题知之甚少。本研究检查了在输出中与目标重叠的词汇竞争对手是否会干扰其识别，并检验了一个被低估的假设，即域一般抑制控制有助于解决词汇干扰。具体来说，在这项研究中，当参与者将鼠标光标移动到他们听到的口头单词的书面单词形式时，视觉世界范式被用来访问词汇激活的时间动态。通过使用汉字，词汇竞争者和目标之间的拼写相似性是独立于它们的语音重叠而被操纵的。结果表明，与控制条件相比，相似条件下的行为表现较差，抑制控制较好的个体（具有较小的 Stroop 干扰效应）表现出对正字竞争者的激活较弱（小鼠轨迹较少被正字竞争者吸引） . 讨论了这些发现对我们理解词汇干扰及其在口语识别中的解决方案的影响。并且具有更好抑制控制的个体（具有较小的 Stroop 干扰效应）表现出对正字竞争者的较弱激活（小鼠轨迹较少被正字竞争者吸引）。讨论了这些发现对我们理解词汇干扰及其在口语识别中的解决方案的影响。并且具有更好抑制控制的个体（具有较小的 Stroop 干扰效应）表现出对正字竞争者的较弱激活（小鼠轨迹较少被正字竞争者吸引）。讨论了这些发现对我们理解词汇干扰及其在口语识别中的解决方案的影响。
