抵制说服:自我损耗对大学生态度改变的影响

Resistance to Persuasion: The Effects of Ego-depletion on Attitude Change of College Students

以87名大学生为被试,采用2(损耗,非损耗)×2(强说服信息,弱说服信息)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的或强或弱的说服信息,再测查其态度及认知反应,考察自我损耗对说服后态度的影响,并进一步考察认知反应在自我损耗与说服后态度关系中的作用。结果发现:(1)损耗组比非损耗组更容易顺从说服信息;(2)自我损耗及说服信息质量对说服后态度的交互作用边缘显著:在非损耗的情况下,个体阅读强、弱不同质量信息产生的态度有显著差异,在损耗情况下,个体阅读强、弱不同质量信息产生的态度差异不显著;阅读强说服信息,损耗组和非损耗组的态度差异不显著,阅读弱说服信息,损耗组的态度显著高于非损耗组;(3)自我损耗不影响个体的总体想法数量,但影响其思维偏好,自我损耗后个体更容易产生与说服信息一致的想法,中介分析表明自我损耗对说服后态度的影响是以思维偏好为中介的。

A sample of 87 participants was selected in the present study, and used a 2 （depleted task or non- depleted task） × 2 （strong argument or weak argument） design to explore how ego-depletion effect on attitude change, and explore further the role of cognitive response between ego depletion and attitude change. Participants completed an initial task designed to deplete or not deplete their regulatory resources, then participants read a message supporting a counterattitudinal policy（ strong or weak）, at last, participants reported their attitude and cognitive responses. Results indicated： （ 1 ） ego depletion affected participants＇ attitude significantly, after ego- depletion,participants more acquiescent. （2） the effect of 2 x 2 interaction was significant, the participants who were non-depleted were able to differentiate between the strong and weak persuasive information; however participants who were depleted showed no distinction in their attitudes. At the same time, the participants who read strong persuasive information showed no distinction in their attitudes whether depleted or not, but the participants who read weak persuasive information showed different significant, the attitude change of students who were depleted was more dramatically. （3） the research showed that depletion didn＇ t impaired the number of cognitions listed by participants＇ about the policy, while significantly affected thought favorability, depleted participants generated more favorable cognitive responses, mediate analysis showed depletion influenced attitude through thought favorability.
