This study was designed to test the effects of different types of influence on the expression of stereotypes towards people who are obese. It was hypothesized that public social pressure would more significantly impact the expression of stereotypes towards obese people than other types of influence.
One-hundred fifty-eight undergraduate students were randomly assigned to one of three conditions or a control condition. Participants completed measures of stereotypes towards obese people prior to and after receiving manipulated feedback depicting purported stereotypes possessed by others (anonymously or publically) or scientific information about the base rates of these stereotypical traits in the obese population (i.e., trait prevalence). Participants also completed a measure of weight bias unrelated to the manipulated feedback.
Explicit beliefs were influenced more when people perceived that others' views were inconsistent with their own in a public setting than an anonymous setting or when they received trait prevalence feedback. However, levels of weight bias on a separate measure were unchanged.
Strong, public manipulations of social feedback have great potential to impact, at least, the short-term expression of stereotypes towards obese people.
本研究旨在测试不同类型的影响对肥胖者刻板印象表达的作用。研究假设，与其他类型的影响相比，公众社会压力对肥胖者刻板印象表达的影响更为显著。
158名本科生被随机分配到三个实验组或一个对照组中。参与者在收到关于他人（匿名或公开）所具有的所谓刻板印象的操纵性反馈或关于肥胖人群中这些刻板特征的基础比率（即特征流行率）的科学信息之前和之后，完成了对肥胖者刻板印象的测量。参与者还完成了一项与操纵性反馈无关的体重偏见测量。
当人们在公开场合而非匿名场合中察觉到他人的观点与自己的观点不一致时，或者当他们收到特征流行率反馈时，明确信念受到的影响更大。然而，单独测量的体重偏见水平没有变化。
强大的、公开的社会反馈操纵至少在短期内极有可能影响对肥胖者的刻板印象表达。
