摘　　要：目的:探讨限制性饮食者在自我调控资源剥夺条件下的过量进食机制。方法:操纵自我调控资源,考察了61名女性(大学生)限制性饮食者和非限制性饮食者在自我调控资源完整、自我调控资源剥夺条件下的进食量,以及该进食量与内隐食物态度、限制性饮食水平的关系。结果:自我调控资源剥夺导致了限制性饮食者的过量进食行为,且该进食量与自我调控资源剥夺条件下的内隐食物态度有关。结论:当自我调控资源不足,限制性饮食者进食享乐目标在引导进食行为中占主导,从而引发过量进食。研究结果支持饮食的目标矛盾模型。Objective： This research sought to investigate the mechanism of the hyperphagia after depleting self-regula- tory resources in the restraint eaters. Methods： 61 female participants（29 restrained eaters, 32 unrestrained eaters） were asked to finish a single-category implicit association task to assess the automatic attitude toward chocolate candy. Then they were instructed to watch a 6-rain voiceless neural video in which several neural words appeared in the bottom while eating M＆M＇ s chocolate candies. Experiment group were told to watch this video and overlook these words purposely at the same time, control group were only asked to watch the video attentively. After self-regulation resource task, they were in- structed to do the taste-test of the chocolate candies, which is widely used as the disguise of the purpose of measuring the food consumption. Finally the participants finish the DEBQ-R, which assessed the intention they want to restraint their food intake. Results： When the self-regulatory resources were depleted, the restraint eaters eat more food than unrestraint eat- ers, while there was no significant differences between two groups when self-regulatory resource is intact. In the restrained eaters, the automatic attitude toward chocolate candy is significantly related to candy consumption when self-regulatory re- source is depleted. Conclusion： These results suggest that when restrained eaters＇ ability to monitor the dietary boundary is impaired, the hedonic goal is in dominant position to direct their food consumption. Further study might distinct the suc- cessful restraint eaters and unsuccessful restraint eaters.
