_SLIDE_3_
Cognitive Control
Congruency Effect
Slowed RTs in Incongruent trial than in Congruent trial
Sequential Congruency Effect
Smaller congruency effects following incongruent trial than following congruent trial
_SLIDE_4_
Conflict Monitoring Account
Conflict in prior trial(Incongruent trial) makes mind
‘be ready for conflict’
-`become more alarmed to task relevant information than to task-irrelevant information
Then, on which conflict monitoring mechanism is based
Task representation
vs
Stimulus dimension
Cognitive Control
_SLIDE_5_
Control mechanism is based on dimension in which task-relevant stimulus is defined
Hypo…(생략)
1) previous trial and next trial both about color congruency
2) previous trial and next trial both about shape congruency
3) previous trial about shape congruency and
4) vice versa of case 3)

Experiment#1 Result
Different dimension
Different dimension
Congruency sequence effect was found
across same domain
(color-color / shape-shape)
AND
across different domain
(color-shape / shape-color)
_SLIDE_13_
It seems that conflict control mechanism is not based on task-relevant stimulus dimension
Then, is it based on task representation
To find out whether cognitive control is operated on the basis of task representation, we constructed experiment2
