在这项研究中，我们调查了人们如何处理不相关的语境信息在言语生产。提出了两种主要模式。WEAVER++假设通过早期阻塞机制从生产系统中删除不相关的信息。另一方面，反应排除假说假设了一种阻塞机制，它在词汇选择完成之后才起作用。为了在这些模型之间进行描述，我们专注于干扰物频率效应（即，较长的图片命名lavery在低频的上下文中相比，高频词）和测量的ERP同时。在行为上，干扰物频率效应被复制。在事件相关电位中，我们发现了三种效应，其中一种效应发生得非常早，被解释为低水平视觉特征加工的效应。另外两个效应发生在词汇通达之后，因此符合反应排除假设。(C)2013 Elsevier Inc.

In this study, we investigated how people deal with irrelevant contextual information during speech production. Two main models have been proposed. WEAVER++ assumes that irrelevant information is removed from the production system by an early blocking mechanism. On the other hand, the response exclusion hypothesis assumes a blocking mechanism that operates late, after lexical selection has finished. To delineate between these models, we focused on the distractor frequency effect (i.e., longer picture naming latencies in the context of low-frequency compared to high-frequency words) and measured ERPs concurrently. Behaviorally, the distractor frequency effect was replicated. In the ERPs, three effects were found. One effect occurred very early and is interpreted as an effect of low-level visual feature processing. The two other effects occurred after lexical access and are thus in line with the response exclusion hypothesis. (C) 2013 Elsevier Inc. All rights reserved.
