Conflict control in task conflict and response conflict

Studies have suggested that conflict control can modulate conflict effects in response to differing levels of conflict context. The current study probed, in two experiments of proportion congruence, the relevance of both task conflict (between a currently relevant task and irrelevant task alternatives) and response conflict (between a currently relevant response and irrelevant response alternatives) to conflict control. In Experiment 1, proportion congruence between blocks was manipulated and in Experiment 2, proportion congruence was manipulated between items. The response conflict effect was smaller when proportion of incongruence was high, regardless if task conflict or response conflict proportions were manipulated. These findings suggest that both task conflict and response conflict are monitored but that only response conflict is being influenced by this monitoring process. Theoretical implications are discussed.
