Abstract: Conflict is currently one of the hot topics in psychology, but the stimulus use or paradigm is the key point that will probably have influence on the validity of findings from the study in the conflict effect and conflict adaptation effect. The present study examined the cognitive and emotional conflict effect and conflict adaptation effect using flanker word task. The result revealed that the response to the incongruent trials was significantly slower and the accuracy was significantly lower than that to the congruent trials in both cognitive and emotional flanker word task, suggesting that either cognitive or emotional word flanker task can produce the conflict effect. The study also found the cognitive conflict adaptation effect, but the emotional conflict adaptation effect was not found due to the task difficulty or different paradigms. Furthermore, the responses to fruit words and negative emotional words were significantly faster than those to metal words and positive emotional words. The accuracy to fruit word and negative emotional word was significantly higher than that to metal word and positive emotional word, especially when the target words and distracters were incongruent. Therefore, future studies may make further improvements on the stimuli or paradigms and heighten the role of neural mechanism on emotional conflict adaptation effect and its relationship to the cognitive conflict adaptation effect.

Key words: cognitive conflict, affective conflict, conflict adaptation, flanker paradigm.
