This study consists of two experiments investigating the effects of induced mood and food type on perceptions of eating in imagined and real eating situations. A total of 212 female undergraduates representing the continuum of bulimic symptomatology were induced with either elated or depressed moods using a standardized mood-induction procedure. They were then either asked to imagine themselves in a situation with either forbidden or non-forbidden foods (Experiment 1) or else were presented with a buffet of forbidden or non-forbidden foods and asked to eat (Experiment 2). Participants subsequently reported their perception of their eating behavior (i.e., amount of control, meal rating: from a snack to a binge; and meal feeling: from great to bad). Results revealed limited support for affect regulation models of bulimia nervosa when the participants consumed food, but no support for the theory when they imagined eating. Conversely, forbidden foods were found to influence perceptions in the imagined eating situation, but not when the participants ate. Implications of these results are discussed.
本研究由两个实验组成，旨在调查诱发情绪和食物类型对想象进食情境和实际进食情境中进食认知的影响。采用标准化情绪诱导程序，对212名代表暴食症状连续体的女大学生诱发了兴高采烈或抑郁的情绪。然后，她们要么被要求想象自己处于有禁食或非禁食食物的情境中（实验1），要么被提供一份有禁食或非禁食食物的自助餐并被要求进食（实验2）。参与者随后报告了他们对自己进食行为的认知（即控制量、用餐评分：从零食到暴饮暴食；以及用餐感受：从好到差）。结果显示，当参与者进食时，对神经性贪食症的情绪调节模型支持有限，但当他们想象进食时，该理论未得到支持。相反，发现禁食食物会影响想象进食情境中的认知，但在参与者进食时则不会。讨论了这些结果的意义。
