摘要

研究背景这项研究提出,根据卡路里含量对食物进行分类的认知偏差可能会导致神经性厌食症(AN)患者限制性进食。本研究试图辨别两个新假设的有效性:(1)神经性厌食症患者更容易根据卡路里含量对食物进行分类,而不是根据其他维度(如可口性)、为了验证这些假设,我们开发了一种新的食物分类任务,并将其提供给了自我报告终生被诊断为进食障碍的患者(48 人)和没有进食障碍病史的患者(133 人)。结果结果显示,相对于对比组,自闭症组以卡路里含量为标准对食物进行分类的速度更快,而对最初以卡路里含量为标准进行分类的食物进行重新分类的速度更慢。

Cognitive biases involving readiness to categorise food in terms of calorie content in anorexia nervosa

Background

This research proposes that cognitive biases involving the categorisation of food in terms of calorie content may contribute to restrictive eating in anorexia nervosa (AN). The current study sought to discriminate the validity of two novel hypotheses: (1) People with AN more readily categorise food in terms of calorie content rather than in terms of alternative dimensions (e.g., tastiness), and (2) people with AN have difficulty reclassifying food initially categorised in terms of calorie content, in terms of alternative dimensions.

Methods

To test these hypotheses, a novel food categorisation task was developed and delivered to people with a self-reported lifetime diagnosis of AN (N = 48) and to people with no history of an eating disorder (N = 133). Participants categorised food in terms of calorie content or tastiness.

Results

Results revealed that the AN group, relative to the comparison group, was faster to categorise food in terms of calorie content and slower to reclassify food initially categorised in terms of calorie content.

Conclusions

These findings suggest that AN is characterised by both an inflated tendency to categorise food in terms of calorie content and to become subsequently stuck on this categorisation.
