The purpose of this study was to investigate how attitude change is generated by the recipient's degree of attitude formation, evaluative-emotional elements contained in the persuasive messages, and source expertise as a peripheral cue in the persuasion context. Hypotheses based on the Attitude Formation Theory of Mizuhara (1982) and the Elaboration Likelihood Model of Petty and Cacioppo (1981, 1986) were examined. Eighty undergraduate students served as subjects in the experiment, the first stage of which involving manipulating the degree of attitude formation with respect to nuclear power development. Then, the experimenter presented persuasive messages with varying combinations of evaluative-emotional elements from a source with either high or low expertise on the subject. Results revealed a significant interaction effect on attitude change among attitude formation, persuasive message and the expertise of the message source. That is, high attitude formation subjects resisted evaluative-emotional persuasion from the high expertise source while low attitude formation subjects changed their attitude when exposed to the same persuasive message from a low expertise source. Results exceeded initial predictions based on the Attitude Formation Theory and the Elaboration Likelihood Model.
本研究的目的是调查在说服情境中，态度改变是如何由接受者的态度形成程度、说服性信息中包含的评价性情感元素以及作为边缘线索的信息源专业性所产生的。基于水原（1982）的态度形成理论和佩蒂与卡乔波（1981年、1986年）的精细可能性模型的假设得到了检验。80名本科生作为实验对象，实验的第一阶段涉及操纵关于核能发展的态度形成程度。然后，实验者从对该主题具有高专业性或低专业性的信息源呈现具有不同评价性情感元素组合的说服性信息。结果显示，在态度形成、说服性信息和信息源专业性之间，对态度改变存在显著的交互作用。也就是说，态度形成程度高的受试者抵制来自高专业性信息源的评价性情感说服，而态度形成程度低的受试者在接触来自低专业性信息源的相同说服性信息时会改变他们的态度。结果超出了基于态度形成理论和精细可能性模型的最初预测。
