People can use inhibitory control to temporarily inhibit their personal preferences to achieve their long-term goals. According to the ego fixation model (Koole et al., 2014), ruminators have difficulties relaxing inhibitory control, leading them to continue inhibiting their personal needs, even when this is no longer required by the situation. Inhibitory control may thus disrupt healthy appetite regulation among ruminators.
Among 324 Dutch undergraduate students (218 women; M = 21.5), different inhibitory control states were manipulated by varying whether or not participants exerted inhibitory control (Study 1) or priming high versus low inhibitory control (Study 2). All participants then performed a food-tasting task. Healthy appetite regulation was defined as a positive correlation between level of food deprivation and preference for high-calorie foods.
For taste ratings, the interaction between inhibitory control and rumination was significant in each study: Inhibitory control disrupted healthy appetite regulation in taste preferences among ruminators, but not among non-ruminators. For eating behavior, the same interaction effect was significant when the two studies were combined.
Inhibitory control disrupts healthy appetite regulation among ruminators. These findings suggest the need for caution in interventions that rely on inhibitory control, especially among samples with compulsive thought tendencies.
人们可以使用抑制控制来暂时抑制个人偏好，以实现长期目标。根据自我固着模型（Koole 等人，2014），反刍者在放松抑制控制方面存在困难，导致他们继续抑制个人需求，即使这种需求不再受到情境的要求。因此，抑制控制可能会破坏反刍者健康的食欲调节。
在 324 名荷兰大学生中（218 名女性；M=21.5），通过改变参与者是否施加抑制控制（研究 1）或启动高抑制控制与低抑制控制（研究 2）来操纵不同的抑制控制状态。所有参与者随后进行了食物品尝任务。健康的食欲调节定义为食物剥夺水平与高热量食物偏好之间的正相关关系。
对于味觉评价，在每项研究中，抑制控制和反刍之间的交互作用都是显著的：抑制控制破坏了反刍者在味觉偏好中的健康食欲调节，但在非反刍者中没有。对于饮食行为，当将两项研究结合起来时，同样的交互效应也是显著的。
抑制控制破坏了反刍者的健康食欲调节。这些发现表明，在依赖抑制控制的干预措施中需要谨慎，特别是在具有强迫性思维倾向的样本中。
