Consumer Contamination: How Consumers React to Products Touched by Others
研究消费者在购物时对他人触碰过的产品评价更低的现象，通过实验验证了厌恶感是背后的心理机制。
Although consumers like to touch products while shopping, the authors propose a theory of consumer contamination, positing that consumers evaluate products previously touched by other shoppers less favorably. The authors test the theory by manipulating cues that increase the salience that consumer contact has occurred. Furthermore, the authors investigate the role of disgust as the underlying mechanism of the theory.
