Abstract

This study is to investigate the brain mechanism of different types of conflict by using the event-related potential(ERP)technique. In order to investigate this issue, this study integrate different types of conflict (such as Flanker,Stroop,and Simon conflict).On the one hand, the behavioral responses data showed that: Firstly, all the types of the conflict in all the experiments show the Congruency Effect and the Conflict Adaptation Effects; Secondly, each type of conflict of previous trial in all the experiment only interacts with its own kind of current trial ,but does not interact with other kind of current trial. On the other hand, ERP data of the two experiments show that: with the exception of Flanker conflict in experiment 2, all the conflict types in all the experiments show that the P300 latency,the N450,and the SP component in line with the Congruency Effect.. The data above show that: Firstly, in a variety of types of conflict condition, the human brain can be able to monitor and then solve the conflict at the same time and also achieve successful task performance, and the conflict monitoring theory are still applicable; Secondly, the human brain use local control mechanism to resolve the conflict. To sum up, multiple conflict-driven control mechanisms are based on the conflict-specific manner, these mechanisms are independent, and free from any interference with each other.
