本研究采用整合的交叉任务范式,通过任务类型的操纵,对冲突适应效应是领域一般的还是领域特定的问题进行了探讨。结果发现当时,在刺激一反应集为4的字母Flanker+Simon的整合交叉任务中和刺激一反应集为4的Stroop+Simon的整合交叉任务中,冲突适应效应都是仅存在于任务内,不存在于任务间。说明在控制了重复启动效应且排除了任务之间维度重叠的影响后,两种类型的整合交叉任务都只在任务内观察到冲突适应效应。这表明在控制特征整合的影响后,冲突适应效应是领域特定的,同时说明冲突监测系统不仅是对冲突进行监测,也对冲突的来源进行识别。
The conflict adaptation effect (CAE), which was the most important empirical evidence for conflict monitoring theory, is that the interference effect was smaller after incongruent trials than after congruent trials in the congruency tasks. However, it is not known whether CAE relies on a single central resource of cognitive control, or on a collection of independent control mechanisms that deal with different types of conflict. Task-switching designs and factorial task-crossing designs were usually used to study the domain of the CAE. In the present research, we used two different factorial task-crossing tasks, which included the flanker task and the Simon task, the Stroop task and the Simon task to explore the scope of the CAE. Experiment 1 and Experiment 2 are both factorial task-crossing design, which contains the letter flanker task and the Simon task, Stroop and the Simon task separately. The similarities between the two experiments are the identical number of stimulus-response set, i. e, four. When the stimulus-response set was four in the flanker task and the Simon task and in the Stroop task and the Simon task, the results indicated that only within-task CAE was present, and there was no cross-task CAE in two tasks. These results indicated that when the stimulus-response set increased to four to eliminate the feature integration effect and to control the influence of dimension repetition, the CAE was task-specific, and the conflict monitor system not only monitored the amount of conflict but also identified the source of the conflict.
