中文摘要：

采用ERP技术记录13例正常青年人在声音诱发的不同情绪条件下,对反应抑制加工过程的影响,并试图阐明其潜在脑机制。实验选择正、中、负三种声音各50种,作为诱发情绪的刺激材料。结果发现Go条件下的反应时在负性、中性、正性条件下依次减短;Go与Nogo刺激均诱发出显著的N1成分,中性条件下波幅显著大于正负性情绪条件。此外,三种情绪背景下,Nogo刺激诱发出显著的N2与P3成分。Nogo-N2主要分布在头皮前中部,在Fz点波幅最大。Nogo-P3主要分布在头皮中部,Pz点波幅最大。中性条件下Nogo-N2波幅显著大于负性与正性条件,而正性和负性之间差异不显著。行为结果表明,听觉负性情绪诱发对反应执行有干扰作用;ERP结果表明声音诱发的情绪对早期听觉选择性注意具有调节作用。听觉情绪诱发对反应抑制加工过程有显著影响,且该影响在早期反应冲突监控阶段最为明显。

英文摘要：

As a central element of executive function, response inhibition includes four main components, namely, stimuli analysis, response selection, conflict monitoring, and behavior inhibition （Lin, Deng, Sun, ＆Li, 2007 ; Goldstein, et al. , 2007）. Two successive components, frontal-central N2 and central-parietal P3, are widely accepted as reflecting conflict monitoring and response inhibition, respectively. Recently, neural mechanisms underlying the interaction of emotion and behavior control have become the focus of a variety of studies. Using event related potential measures and an emotional Go/Nogo task, the present study aimed to explore the neural correlates of the influence of auditory emotions on response inhibition, which may provide an insight into our understanding of the interaction of emotion and executive function. 50 kinds of positive, neutral and negative voice pieces were selected as emotional prime materials. 400HZ and 1400 HZ tones were used as Go/Nogo signals. Block design method was adopted according to the valence of emotional context. Therefore, the experiment was divided into three blocks： negative, neutral and positive. The sound used in each block shared the same valence and induced a kind of emotion. The presentation of emotional sound which lasted for 5000ms was followed by the onset of Go/Nogo signal. The presentation of Go and Nogo tones were terminated by a key pressing or when it elapsed for 300ms. ERPs were recorded for Go and Nogo signals during a typical Go / Nogo task. At the end of each block, participants were asked to fill the Positive Affect and Negative Affect Schedule, in order to measure their subjective affective feelings （Watson D, Clark L A, ＆ Tellegen A, 1988）. The behavioral data demonstrated the longest response latency under the negative prime than under positive and neutral prime conditions, whereas the latter two conditions showed no differences. Moreover, prominent N1 component was elicited during Go and Nogo conditions, irrespective of the valence of
