There is experimental evidence to suggest that attentional bias to food stimuli may predict food intake. The process model of ego-depletion (Inzlicht & Schmeichel, 2012) proposes that after self-control exertion, attention shifts toward rewarding objects such as palatable food, which in turn should prompt greater food consumption as an indicator of lower self-control. In the current study, 84 female restrained and unrestrained eaters engaged in a self-control or neutral task, followed by a measure of attentional bias and an eating task. Results indicated there were no differences in attentional bias or amount eaten between self-control conditions and dietary restraint groups. However, a moderated regression showed that attentional bias toward food or self-control images predicted eating behavior only in participants who previously exerted self-control, while no effect was found for participants in the neutral condition. These results suggest that attentional bias may predict food intake, but only for individuals who have previously exerted self-control.
有实验证据表明,对食物刺激的注意力偏向可能预测食物摄入量。自我损耗的过程模型(Inzlicht和Schmeichel,2012)提出,在进行自我控制后,注意力会转向诸如美味食物等奖励性物品,这反过来又会促使更多的食物消费,作为较低自我控制的一个指标。在本研究中,84名女性节食者和非节食者参与了一项自我控制或中性任务,随后进行了注意力偏向测量和进食任务。结果表明,自我控制条件和饮食限制组之间在注意力偏向或进食量上没有差异。然而,一项调节回归显示,对食物或自我控制图像的注意力偏向仅在先前进行过自我控制的参与者中预测进食行为,而在中性条件下的参与者中未发现此效应。这些结果表明,注意力偏向可能预测食物摄入量,但仅适用于先前进行过自我控制的个体。
