不同事件卷入度下自我损耗对态度改变的影响

The Effects of Ego-depletion on Attitude in Different Level of Issue Involvement

目的:采用双任务实验范式,考察不同事件卷入度下自我损耗对态度改变和思维偏好的影响。方法:以76名大学生为被试,采用2(损耗,非损耗)×2(高卷入度,低卷入度)的实验设计,让被试完成损耗或非损耗任务后,阅读与其已有观念相反、卷入程度不同的说服信息,再测量其态度,考察自我损耗及卷入程度对个体说服后态度、思维偏好的影响。结果:事件卷入度与自我损耗对说服后态度及思维偏好的交互作用显著:事件卷入程度高时,自我损耗对态度变化及思维偏好没有显著影响;卷入程度低时,自我损耗显著影响了态度变化及思维偏好,自我损耗后的个体更容易被说服,产生更多与说服信息一致的看法。结论:高事件卷入程度可以起到弥补自我损耗的作用,使个体更倾向于保持原有态度。

Objective: This study aimed to explore how ego-depletion affects attitude and thought favorability using dual-task paradigm. Methods: The study designed 2(depleted task or non-depleted task)×2(high level of issue involvement or low level of issue involvement) experiment. Seventy-six university students were recruited and randomized assigned as depleted group, non-depleted group, then they read a message supporting a counter-attitudinal policy(high level or low level of issue involvement), at last, they reported their attitude and thought favorability. Results: The effects of 2×2 interaction were significant, the participants who read high level involvement showed no distinction in their attitude and thought favorability whether depleted or not, but the participants who read low level involvement showed different significant, the attitude change and thought favorability who were depleted were more dramatically. Conclusion: High level of issue involvement may depress ego-depletion and make individual to maintain the original attitude.
