摘　　要：目的探究基于多冲突驱动的认知控制机制。方法采用事件相关电位(ERPs)技术考察,并整合了Stroop冲突、Simon冲突和Flanker冲突。结果行为数据表明在各种冲突中都出现了一致性效应和冲突适应性效应。脑电数据表明,所有冲突都发现了P300、N450、SP成分的一致性效应。结论在多冲突条件下,冲突监控理论对于其中的各种冲突仍然适用;冲突驱动的认知控制系统以局部的控制方式工作;人脑是基于多冲突驱动的认知控制系统的灵活性和某类型冲突所特有的控制机制来解决冲突的,且冲突解决机制相互独立、互不干扰。Objective To investigate the brain mechanism elicted by multiple conflict.Methods This study integrated different types of conflict,including Flanker,Stroop and Simon conflict,by using the event-related potential（ERP） technique.Results The behavioral data showed that there were the congruency effect and the conflict adaptation effect in all types of the conflict.ERP data showed that the congruency effects of P300,N450 and SP component were found in all types of conflict.Conclusion The conflict monitoring theory is still available for various types of conflict in multiple conflict conditions and the human brain uses local control mechanism to resolve the conflict.In addition,the human brain resolves the conflict based on the flexibility of cognitive control system driven by multiple conflict and the conflict-specific control mechanisms.These mechanisms are independent and free from any interference with each other.
