Based on compensatory control theory, the aim of this study was to examine the effects of perceived control on people's acceptance of genetically modified (GM) foods by using both correlational and experimental methods. Compensatory control theory proposes that the lower an individual's perceived control, the higher their need for structure, order, and certainty. Therefore, based on beliefs about GM foods that make some people less certain that those foods are as safe as traditional foods, we hypothesized that individuals with lower levels of perceived control are more inclined to reject GM foods. The analysis of questionnaire responses in Study 1 revealed that individuals' sense of control negatively predicted their risk perception of GM foods, while the need for structure played a mediating role. In Study 2, using a between-subject design, we manipulated participants' perceived control (higher vs. lower) and subsequently measured their risk perception and purchasing preferences for GM foods. The results in Study 2 show that under lower control conditions, individuals recognize higher risks related to GM foods, which, in turn, decreases their willingness to purchase GM foods. These results not only suggest that perceived control is a potential influential personal factor of the acceptance of GM foods but also extend the scope of the application of compensatory control theory.
基于补偿性控制理论,本研究采用相关和实验方法,旨在探讨感知控制对人们接受转基因食品的影响。补偿性控制理论认为,个体感知控制越低,他们对结构、秩序和确定性的需求就越高。因此,基于一些人对转基因食品不太确定的信念,认为这些食品与传统食品一样安全,我们假设感知控制水平较低的个体更倾向于拒绝转基因食品。研究 1 中对问卷回答的分析表明,个体的控制感负向预测了他们对转基因食品的风险感知,而结构需求则起到了中介作用。在研究 2 中,我们采用了被试间设计,操纵了参与者的感知控制(高 vs. 低),然后测量了他们对转基因食品的风险感知和购买偏好。研究 2 的结果表明,在较低的控制条件下,个体认识到与转基因食品相关的更高风险,这反过来又降低了他们购买转基因食品的意愿。这些结果不仅表明感知控制是接受转基因食品的一个潜在影响因素,还扩展了补偿性控制理论的应用范围。
