之前的研究已经将暴饮暴食和超重/肥胖与冲动联系在一起。为了找出冲动是否会导致暴饮暴食，从而导致超重和肥胖，我们试图在健康的参与者中启动冲动的概念。在受试者内部设计中，一个样本参与了两个条件。在两种情况下，参与者都完成了一项启动任务，要么微妙地暗示冲动的概念，要么在内容上是中性的。每次启动任务之后都会进行一次虚假的品尝测试。通过行为任务和自我报告来测量特质冲动性。首先，我们假设，与控制组相比，受试者在接受了“冲动”这个概念后，在品尝测试期间会吃得更多。其次，我们预计更冲动的个性会预示着更高的食物摄入量。第三，我们预计冲动会比节制更好地预测食物摄入量。结果表明，冲动的自我报告和行为任务都能预测食物的摄入量。节制并不能显著预测食物摄入量。启动冲动并没有增加食物的摄入量，可能是因为启动效应持续的时间不够长。(C)2007爱思唯尔有限公司。保留所有权利。
Previous research has linked overeating and overweight/obesity to impulsivity. To find out whether impulsivity causes overeating and hence overweight and obesity, we attempted to prime the concept of impulsivity in healthy participants. In a within-subjects design one sample participated in two conditions. In both conditions participants did a priming task that either hinted subtly at the concept of impulsivity or that was neutral in content. Each time the priming task was followed by a bogus taste test. Trait impulsivity was measured by means of a behavioural task and self-report. Firstly, we hypothesized that participants would eat more during the taste test after they had been primed with the concept "impulsivity" compared to after the control session. Secondly, we expected that a more impulsive personality would predict a heightened food intake. Thirdly, we expected that impulsivity would predict food intake better than restraint. The results showed that both the self-report measure of impulsivity and the behavioural task predicted food intake. Restraint did not significantly predict food intake. Primed impulsivity did not increase food intake, possibly because the priming effect did not last long enough. (c) 2007 Elsevier Ltd. All rights reserved.
