In everyday life cues and signs are used in order to improve our performance and to modify and control our behavior. This study examines whether cues can improve the performance of the mental mechanism in charge of solving conflicts when the nature of the irrelevant task remains constant. In two experiments participants performed the Stroop task in which they were asked to name the color of a stimulus while ignoring its meaning. Half the trials were preceded by a conflict-cue containing information about an upcoming conflict. In addition, conflict trial proportions were manipulated. We found that only when the probability of conflict is low can cues alter the conflict solving mechanism. These findings are discussed in the context of the nature of the control mechanism and its tendency to minimize the cost of mental resources.
在日常生活中，线索和信号被用于提高我们的表现，并改变和控制我们的行为。本研究考察了当无关任务的性质保持不变时，线索是否能改善负责解决冲突的心理机制的表现。在两个实验中，参与者执行了斯特鲁普任务，即要求他们在忽略刺激意义的同时说出刺激的颜色。一半的试验之前会出现一个包含即将到来的冲突信息的冲突线索。此外，还对冲突试验的比例进行了操纵。我们发现，只有当冲突概率较低时，线索才能改变冲突解决机制。这些发现将在控制机制的性质及其使心理资源成本最小化的倾向的背景下进行讨论。
