Cognitive control adjusts information processing to momentary needs and task requirements. We investigated conflict adaptation when participants are performing two tasks, a Simon task and a SNARC task. The results indicated that one congruency effect (e.g., Simon) was reduced after conflict in the other task (e.g., SNARC), but only when both tasks used identical relevant information. On the other hand, when both tasks used different relevant information, a larger congruency effect was observed after conflict in the other task. The results are explained in terms of a local control mechanism.
认知控制根据瞬间需求和任务要求调整信息处理。我们研究了参与者执行两项任务（一项西蒙任务和一项SNARC任务）时的冲突适应情况。结果表明，在另一项任务（如SNARC任务）中出现冲突后，一种一致性效应（如西蒙效应）会减弱，但前提是两项任务都使用相同的相关信息。另一方面，当两项任务使用不同的相关信息时，在另一项任务出现冲突后会观察到更大的一致性效应。这些结果是根据局部控制机制来解释的。
