不同认知方式对词—面孔任务Stroop效应的影响

该研究采用词—面孔Stroop任务,以76名大学生为被试,探讨了不同认知方式（场独立、场依存）对情绪冲突Stroop效应的影响。结果发现：（1）情绪冲突的Stroop效应显著,即,在词—面孔Stroop任务中,当词和面孔的情绪效价一致时,被试的反应时更短,正确率更高。（2）认知方式对情绪冲突Stroop任务的影响显著,表现为无论是一致还是不一致条件下,场独立者比场依存者的反应时都更短。（3）场依存者的情绪冲突Stroop效应更大,表现为其在词—面孔情绪效价一致和不一致条件下的反应时差异更大。

The Effects of Cognitive Styles on the Word- Face Stroop Task

Using the word- face task,the effects of cognitive styles on the Stroop effect of emotional conflict were explored with a sample of 76 undergraduates. It showed that：（ 1） The Stroop effect of emotional conflict was significant. In the word- face task,when the emotional valence of the word was consistent with that of the face,participants had shorter reactive time and higher accuracy than they did when the emotional valence of the word was not consistent with that of the face.（ 2） The effect of cognitive style on the Stroop task was also significant. Despite the experimental conditions,field- independent participants had shorter reactive time than field- dependent ones did.（ 3） Field- dependent participants had larger Stroop effect than field- independent ones did. Their difference in reactive time between the two conditions of word- face task was larger than that of field- independent ones.
