背景和目的：当缺乏抑制控制时，人们更容易沉迷于高热量食物。本研究考察了增加抑制性控制和减少抑制性控制是否会对食物摄入产生相反的影响。方法：在本研究中，使用停止信号任务来测量基线抑制性控制能力。接下来，受试者在三种情况下执行一项改进的停止信号任务：一种类型的高卡路里食物总是伴随着停止信号(抑制操作)，而另一种类型的高卡路里食物从未出现过停止信号(冲动操作)。在控制条件下，高卡路里食物在一半的试验中显示了停止信号。结果：抑制控制能力低的受试者比抑制控制能力强的受试者摄入了更多的对照食物。然而，抑制操作将抑制控制水平较低的参与者的食物摄入量减少到与抑制控制水平高的参与者相同的水平。相反，冲动控制使抑制控制水平较高的被试的食物摄入量增加到抑制控制水平较低的被试的饮食水平。结论：这些发现证实了抑制在进食行为中的因果作用，并提示加强抑制控制可以帮助人们重新控制高热量食物的消费。(C)2011爱思唯尔有限公司。保留所有权利。
Background and objectives: When inhibitory control is lacking, people are more prone to indulge in high calorie food. This research examined whether increasing or decreasing inhibitory control influences food intake in opposite directions.Methods: In this study, baseline inhibitory control ability was measured with the Stop Signal Task. Next, participants performed a modified Stop Signal Task with three within-subjects conditions: One type of high calorie food was always paired with a stop signal (inhibition manipulation), while another type of high calorie food was never presented with a stop signal (impulsivity manipulation). In the control condition, high calorie food was presented with a stop signal on half the trials. Following the manipulation, intake of the three food products that were used in the manipulation was measured during a taste test.Results: Participants with low inhibitory control abilities consumed more of the control food compared to participants with high inhibitory control abilities. However, the inhibition manipulation decreased food consumption in participants with low levels of inhibitory control to the same level of food intake as that of participants with high levels of inhibitory control. Conversely, the impulsivity manipulation increased food intake in participants with high levels of inhibitory control to the level of consumption of participants with low levels of inhibitory control.Conclusions: These findings demonstrate the causal role of inhibition in eating behavior and suggest that strengthening inhibitory control can help people regain control over the consumption of high calorie food.
