In two studies, it was examined whether dietary restraint is associated with stronger positive implicit attitudes toward high calorie food. This hypothesis was tested using unipolar IAT variants that allowed us to separately measure and examine positive and negative implicit associations with high calorie food. In both studies, results showed that restrained eaters do not differ from unrestrained eaters with respect to negative implicit associations with high calorie food. However, dietary restraint does influence the strength of positive implicit associations with high calorie food: When positive implicit associations with high calorie food were measured relative to low calorie food, restrained and unrestrained eaters did not differ with respect to their implicit preferences for high versus low calorie food. In contrast, when positive implicit associations with high calorie food were assessed using non-relative IAT variants, restrained eaters showed stronger positive implicit associations with high calorie food than unrestrained eaters. Thus, restrained eaters show stronger implicit liking for high calorie food compared to unrestrained eaters.
在两项研究中,研究了饮食克制是否与对高热量食物的积极内隐态度更强有关。使用单极 IAT 变体来检验这一假设,这允许我们分别测量和检查与高热量食物的积极和消极内隐关联。在两项研究中,结果表明,与无克制饮食者相比,克制饮食者在对高热量食物的消极内隐关联方面没有差异。然而,饮食克制确实会影响对高热量食物的积极内隐关联的强度:当测量与高热量食物相比时,与低热量食物的积极内隐关联时,在对高卡路里食物与低卡路里食物的内隐偏好方面,克制饮食者和无克制饮食者没有差异。相比之下,当使用非相对 IAT 变体评估与高热量食物的积极内隐关联时,克制饮食者对高热量食物的积极内隐关联比无克制饮食者更强。因此,与无克制饮食者相比,克制饮食者对高热量食物表现出更强的内隐喜爱。
