Many people change their eating behavior as a consequence of stress. One source of stress is intrapersonal psychological conflict as caused by discrepancies between implicit and explicit motives. In the present research, we examined whether eating behavior is related to this form of stress. Study 1 (N=53), a quasi-experimental study in the lab, showed that the interaction between the implicit achievement motive disposition and explicit commitment toward an achievement task significantly predicts the number of snacks consumed in a consecutive taste test. In cross-sectional Study 2 (N=100), with a sample of middle-aged women, overall motive discrepancy was significantly related to diverse indices of unsettled eating. Regression analyses revealed interaction effects specifically for power and achievement motivation and not for affiliation. Emotional distress further partially mediated the relationship between the overall motive discrepancy and eating behavior.
许多人会因为压力而改变他们的饮食习惯。压力的一个来源是内在的心理冲突，这种冲突是由内隐和外显动机之间的差异引起的。在本研究中，我们考察了饮食行为是否与这种形式的压力有关。研究 1（N=53）是一项实验室中的准实验研究，结果表明，内隐成就动机倾向和外显成就任务承诺之间的相互作用显著预测了连续味觉测试中所消耗的零食数量。在横断面研究 2（N=100）中，我们对中年女性进行了研究，结果表明，总体动机差异与各种不规律的饮食行为显著相关。回归分析显示，这种关系仅针对权力和成就动机存在交互作用，而与亲和动机无关。情绪困扰进一步部分中介了总体动机差异与饮食行为之间的关系。
