Abstract

Background: In this study, we examined whether a persuasive message in favor of a pro-environmental proposal could influence attitude change through a self-validation process when individuals were told that the source of the proposal belonged to their ingroup (vs. their outgroup).

Method: Participants read a message that advocated for the use of solar power. Immediately following the message, participants were asked to list their thoughts regarding the persuasive proposal. A thought favorability index was created for each participant. Following the thought-listing task, participants received the experimental manipulation (i.e., ingroup vs. outgroup source) based on the minimal group paradigm, after which they reported their attitudes towards the proposal.

Results: A regression analysis showed the predicted interaction between thought favorability and type of source (i.e., ingroup vs. outgroup) on attitudes towards the solar power proposal. According to our expectations, thought favorability was a better predictor of attitudes for participants in the ingroup (vs. outgroup) source condition.

Conclusions: Attitudes can be polarized as a function of ingroup versus outgroup differentiation through a self-validation process.

改变对太阳能发电环保提案的态度：同类与异类来源的自我验证作用。

研究背景在这项研究中，我们考察了当个体被告知建议的来源属于他们的内群体（相对于他们的外群体）时，支持环保建议的说服性信息是否能够通过自我验证过程影响态度的改变：方法：参与者阅读一条倡导使用太阳能的信息。方法：受试者阅读了一条倡导使用太阳能的信息，紧接着，受试者被要求列出他们对这条具有说服力的建议的想法。我们为每位参与者创建了一个思想好感度指数。在思想列表任务之后，参与者接受了基于最小群体范式的实验操作（即内群与外群来源），之后他们报告了自己对提案的态度：回归分析表明，思想好感度与来源类型（即内群与外群）对太阳能发电提案的态度之间存在预期的交互作用。正如我们所预期的那样，对于处于内群体（与外群体）来源条件下的参与者来说，思想好感度能更好地预测他们的态度：结论：通过自我验证过程，人们的态度会因群体内与群体外的差异而两极分化。
