中文摘要： 冲突控制是个体排除或减少无关信息干扰适应环境的过程，调节其表现可使个体提高行为效率和保持心理健康。建立冲突控制调节系统的基础是认识冲突控制的机制。关于单感觉通道冲突控制的机制有广泛共识，但跨感觉通道冲突控制机制还不明确，缺乏调节个体跨感觉通道冲突控制的策略。生活中的信息多以跨感觉通道形式出现，为了建立生态效度高的冲突控制调节系统，本项目将采用事件相关电位（ERPs）技术，从“视-听”、“视-嗅”、“视-味”和“视-触”方面探讨跨感觉通道冲突控制的认知神经机制，以此为基础建立跨感觉通道冲突控制调节系统。由于各类感觉信息加工速度的区别，不同类型跨感觉通道冲突控制机制可能存在差异，需采用不同干预方法（行为训练或信息调整）来调节个体跨感觉通道冲突控制的表现。本项目的展开不仅对认识冲突控制的内在机制有重要理论意义，同时也能为人们在现实生活中灵活处理冲突信息及有效适应环境提供启示。

英文摘要： Conflict control is a process in which the individuals eliminate or reduce the irrelevant information interference to adapt to the environment. The adjustment of the conflict control improves the behavior efficiency and keeps the mental health. Understanding the mechanism of the conflict control is the basis of establishing the regulation system of the conflict control. The results about the cognitive and neural mechanism of single channel conflict control reach a consensus, but the cognitive and neural mechanism of the cross-modal conflict control is not clear. There is no strategy to adjust the individual's performance on the cross-modal conflict control. Information in the life turns up in the cross-modality form. In order to establish the regulation system of the conflict control with the high ecological validity, this project will use the event related potential (ERPs) technology, from visual-audio, visual-olfactory, visual-taste and visual-touch aspects to explore the cognitive and neural mechanism of the cross-modal conflict control. Based on the results, this project will try to establish the cross-modal conflict control regulation system. The processing speeds of various sensory information are distinct. Differences on the cognitive and neural mechanism of the different cross-modal conflict controls are expected. We should use the different interventions(behavior training or information adjustment) to change the individual cross-modal conflict control performance. The work of this project has important theory significance to understand the essence of the conflict control, as well as provides an important insight for the adjustment of the conflicting information processing and the effectively safe adaption in the daily life.
