Dieting is a popular but difficult strategy for reducing weight. Previous studies have revealed several psychological characteristics associated with dieting failure. Here, the hypothesis that dieting failure is associated with unconscious hedonic responses to food was tested with a subliminal affective priming task. Food image primes or their scrambled mosaic primes were subliminally presented. Participants scored their liking of the subsequent target ideographs. The participants' subjective dieting success was additionally assessed using questionnaires. Differences in liking scores of target ideographs between the food and mosaic conditions, as well as liking scores of target ideographs under the food condition by partialing-out other effects, were negatively associated with dieting success scores. These results suggest that dieting failure is associated with the strength of unconscious hedonic responses to food and that environmental controls to reduce food cues may be needed for dieting success.
节食是一种流行但难以实施的减肥策略。先前的研究揭示了与节食失败相关的几种心理特征。在此，通过一项阈下情感启动任务，对节食失败与对食物的无意识享乐反应相关这一假设进行了测试。阈下呈现食物图像启动刺激或其打乱的镶嵌图启动刺激。参与者对随后的目标表意文字的喜爱程度进行评分。另外，使用问卷评估参与者主观的节食成功情况。食物条件和镶嵌图条件下目标表意文字喜爱程度评分的差异，以及通过排除其他影响因素得出的食物条件下目标表意文字的喜爱程度评分，均与节食成功评分呈负相关。这些结果表明，节食失败与对食物的无意识享乐反应强度相关，并且节食成功可能需要减少食物线索的环境控制。
