目的：以往的研究表明，反应抑制、暴饮暴食和超重之间存在密切关系。研究表明，反应抑制无效的人更容易受到美味食物的诱惑，吃得更多，而且更容易超重或肥胖。此外，几项研究的结果表明，需要抑制的可能是情感驱动的食物动机。因此，在本纵向研究中，我们调查了反应抑制和对零食的内隐偏好在预测体重增加方面的相互作用。设计：在以正常体重为主的本科女生样本中，测量了对食物的内隐偏好、反应抑制和身体质量指数（BMI）。1年后，再次测量BMI。主要观察指标：1年内受试者体重增加情况。结果与结论：结果有力地证实了我们的预期：对休闲食品有强烈内隐偏好和抑制能力低的参与者体重增加最多。这些发现表明，无效的反应抑制通常会使人们容易产生过度或冲动的行为，但其表现是由特定领域的偏好或需求决定的。
Objective: Previous research showed a strong relation between response inhibition, overeating and overweight. It was shown that people with ineffective response inhibition are more susceptible to the temptations of palatable food, eat more and are more often overweight or obese. In addition the results of several studies suggest that what needs to be inhibited may be an affect-driven motivation for food. In the present longitudinal study, we therefore investigated the interplay of response inhibition and implicit preferences for snack foods in predicting weight gain. Design: In a sample of predominantly normal weight undergraduate female students, implicit preference for food, response inhibition, and body mass index (BMI) were measured. After 1 year, BMI was measured again. Main Outcome Measures: Weight gain of the participants over a 1-year period. Results and Conclusions: The results strongly confirmed our expectations: participants with strong implicit preferences for snack foods and low inhibitory capacity gained the most weight. These findings imply that ineffective response inhibition may render people vulnerable to excessive or impulsive behavior in general, but that the manifestation thereof is determined by domain-specific preferences or needs.
