ABSTRACT
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.
ABSTRACT
Objective To study face recognition rule of Chinese subjects during judging the differences of facial recognition of race,gender and their joint property.Methods Eye tracking technique and moving window experimental method were used.Results The present results showed that,in facial race recognition,gender recognition and joint property recognition,the key area of face recognition was eyebrow and eye.In face recognition process,the dominant area in face of information acquired was right facial area.The key brain area of facial cognition was right brain area.Conclusion The recognition performance of face racial recognition is the best than face gender recognition and joint property recognition.Asymmetrical perception effect in human face area is appeared in facial recognition.
