悲伤的人可能会沉迷于使人发胖的零食，因为他们相信吃东西会修复他们的情绪。为了测试（1）期望和情绪的变化是否会影响热量摄入，以及（2）抑郁症状是否会调节热量摄入，73名患有暴食症的女性被随机分配到一个条件下，其中对食物和情绪的期望被证实或不被证实。随后，研究人员向他们展示了一段令人沮丧或有趣的电影片段，然后进行了一项品尝任务。与我们的预期相反，这四种情况下没有差异：所有四种情况下的参与者都摄入了相当数量的卡路里。操纵期望或情绪对热量摄入没有影响。然而，更高的基线期望，食物是愉快的和有用的奖励导致更高的热量摄入后，积极的情绪诱导。非抑郁个体在消极情绪诱导后比抑郁个体吃得少。有趣的是，他们也比那些情绪被积极诱导的人吃得更少，无论他们是否抑郁。非抑郁症患者似乎使用更健康的应对策略：负面影响表明环境存在问题。另一方面，积极的影响表明环境是良性的，因此使人们对食物摄入的警惕性降低。(C)2009爱思唯尔有限公司保留所有权利。
Sad people may indulge in fattening snacks because they believe that eating will repair their mood. To test whether (I) changes in expectations and mood had an effect on caloric intake and (2) depressive symptoms moderated caloric intake, 73 women with binge eating disorder were randomly assigned to a condition in which expectations about food and emotion were either confirmed or disconfirmed. Subsequently they were shown either an upsetting or an amusing movie clip followed by a taste task. Contrary to our expectations, there were no differences in the four conditions: participants in all four conditions ate comparable amounts of calories. Manipulation of expectations or mood had no effect on caloric intake. However, higher baseline expectations that food is pleasurable and useful as a reward resulted in a higher caloric intake after positive mood induction. Non-depressed individuals ate less after a negative mood induction than did depressed individuals. Interestingly, they also ate less than the group of individuals, depressed and not, whose mood was positively induced. Non-depressed individuals seem to use healthier coping strategies: negative affect signals that the environment poses a problem. Positive affect on the other hand signals that the environment is benign, and thus makes people less vigilant about food intake. (C) 2009 Elsevier Ltd. All rights reserved.
