【摘要】：评价性条件作用(Evaluative Conditioning,简称EC)是通过将条件刺激与具有积极效价或消极效价的非条件刺激的配对呈现来改变个体对于条件刺激喜爱度的一种实验室操作程序。大量研究表明,EC能够改变我们对于条件刺激的外显态度和内隐态度,而关与EC对于行为的影响则少有涉及。本研究以巧克力作为高热量食物的代表,探讨了通过EC程序的操控,被试对于巧克力的外显态度、内隐态度、以及巧克力消耗量的变化。本实验为单变量被试间设计,88名女性被试被随机分配到巧克力——积极组或者巧克力——消极组。实验任务主要分为两个部分,第一部分均需要在电脑上进行,包括EC程序的呈现、外显态度测量、内隐态度测量、条件联结觉察测量,这些程序都使用E-Prime2.0软件编制；第二部分为纸质问卷测量,包括巧克力评价问卷以及收尾补充问卷。研究结论：(1)EC程序的操控对被试的外显态度和内隐态度的影响显著,与巧克力——消极组被试相比,巧克力——积极组被试对于巧克力的外显态度和内隐态度都更积极；并且EC程序的操控对巧克力外显态度影响的效应量大于对巧克力内隐态度影响的效应量；(2)EC程序的操控对被试的巧克力消耗量的影响显著,与巧克力——消极组被试相比,巧克力——积极组被试的巧克力消耗量更高；(3)被试对巧克力的外显态度能够有效地预测对于巧克力的消耗量；(4)在EC程序影响被试巧克力消耗量的过程中,外显态度起到了中介作用。
[Abstract]:Evaluation of condition (Evaluative Conditioning, referred to as EC) is the unconditioned stimulus and stimulus conditions has a positive or negative valence valence pairing appears to change the individual for a laboratory procedure. The conditioned stimulus like a large number of studies show that EC can change our explicit attitude and implicit attitude to the conditioned stimulus the influence of EC, and the behavior are less involved. In this study, chocolate as a representative of high calorie foods, are discussed through the EC program control subjects for chocolate explicit attitude and implicit attitude, and the change of chocolate consumption. This experiment is a single variable between subjects design 88 female subjects were randomly assigned to group or chocolate - Chocolate - positive negative group. The experimental task is mainly divided into two parts, the first part is needed on the computer, including the EC program Present, explicit attitude measurement, implicit attitude measurement conditions, these procedures are aware link measurement, using E-Prime2.0 software; the second part is the paper questionnaire, including evaluation questionnaire and questionnaire of chocolate finishing. Conclusions: (1) effects of EC program control of explicit attitude and implicit attitude on the outside obviously, with the chocolate - negative group participants compared to positive subjects for chocolate - chocolate, explicit and implicit attitudes are more positive effect and scale effect; EC program control of attitude influence on chocolate outside the big effect on chocolate implicit attitude; (2) EC program control the subjects of chocolate consumption significantly, and the negative group was compared with chocolate, chocolate -- positive subjects chocolate consumption higher; (3) the subjects of chocolate can have explicit attitude The consumption of chocolate was predicted, and (4) in the process of influencing the consumption of chocolate in the EC program, the explicit attitude played an intermediary role.
