摘　　要：作为制约二语听力理解的主要情感变量之一,焦虑情绪已经引起国内外研究者的广泛关注。然而,以往研究重点描述焦虑对第二语言听力理解产生影响这一现象,缺乏对这一心理过程工作机制的探讨。本文基于资源竞争理念,从情绪与信息加工的心理机制与神经基础两方面,探究焦虑情绪与执行控制过程之间的交互影响机制。我们认为,在听力理解过程中,外显的焦虑情绪削弱大脑的执行控制能力,进而降低工作记忆的加工效率,最终导致对二语听力理解的负性影响。It is widely acknowledged that anxiety, one of the affective variables, has produced a profound negative effect on the second language listening comprehension. However, the previous studies mainly described this phenomenon, failing to explicate its wor- king mechanisms. Based on the notion of resource competition, this paper intends to explore the intrinsic interaction mechanisms between anxiety and executive control from the perspectives of neural basis as well as psychological mechanism of emotion and in- formation processing. We infer that in the process of listening comprehension, the explicit anxiety emotion influences listening comprehension negatively by impairing the cerebral executive control and then decreasing working memory efficiency.
