单纯呈现人脸刺激诱发Stroop反应冲突的实验研究

摘要：该研究以人脸图片与形容词为刺激材料,以大学生为被试,采用了与词－面孔Stroop范式类似的方法来验证单纯呈现效应。先向被试随机呈现两组经评定为中等评价的人脸图片，其中一组呈现十次，另一组呈现一次，以诱发单纯呈现效应。再向被试呈现已叠加形容词的人脸图片，形容词是对人积极的或消极的评价，人脸图片是先前呈现过的，要求被试判断词是积极的还是消极的。结果发现, 被试对呈现次数少的人脸图片叠加积极形容词后的反应时与叠加消极形容词后的反应时无显著差异，而对呈现次数多的人脸图片叠加积极形容词后的反应时则显著短于叠加消极形容词后的反应时，成功验证了单纯呈现效应，也说明了实验方法的有效性。

The Effects of Mere Exposure and the Generation of Stroop-like response conflicts

Abstract The research uses face images and adjectives as stimulus material, a total of 36 students as participants, by a method similar to the word - face Stroop paradigm to verify the mere exposure effect. Firstly, two groups of medium-evaluated face images were presented to the participants randomly, one group was presented ten times while another group one time to induce the mere exposure effect. Then the presented images with positive or negative people evaluation adjectives were presented to participants again, and ask the participants to decide whether the word is positive or negative. The result indicated that, to the less times presented images, there was no significant difference of reaction time between positive adjectives attached and negative adjectives attached, however, on the other hand, to the more times presented images, the reaction time of images with positive adjectives attached was significantly shorter than the images with negative adjectives attached. This phenomenon successfully verified the mere exposure effect, as well as the effectiveness of experiment method at the same time.
