限制性饮食者对食物线索的记忆偏向

Abstract

限制性饮食是为了控制体重，长期严格地控制进食的倾向。记忆是指对外界信息编码、存储和提取的过程，过去的信息和经验通过记忆对现在及未来的行为进行指导。已有研究证实，相对于非限制性饮食者，限制性饮食者对食物线索存在记忆偏向。未来研究有必要全面考察限制性饮食者在不同记忆加工阶段的认知特点，对成功和失败两种亚类限制性饮食者对不同类型的食物线索的记忆偏向分别进行研究，注重脑机制的探讨，找出食物线索加工背后的认知神经机制，为实践改变和临床治疗提供理论依据。 Restrained eating refers to propensity to restrict food intake in order to keep weight. Memory is a cognitive processing of encoding, storage and extracting information. Information and experience in the past provide guidance to present and future behavior with the help of memory. Previous researches verified that compared with unrestrained eaters, restrained eaters had memory bias towards food-related cues. Future studies should be conducted to clarify cognitive characteristics in different memory stages of restrained eaters, and sub-groups of restrained eaters (successful restrained eaters and unsuccessful restrained eaters). Different food types should also be taken into consideration to find out cognitive mechanism of restrained eaters, thus providing theory to clinical treatment.
