Maladaptive cognitions about food, weight and shape bias attention, memory and judgment and may be linked to disordered eating behaviour. This paper reviews information processing of food stimuli (words, pictures) in people with eating disorders (ED).
PubMed, Ovid, ScienceDirect, PsychInfo, Web of Science, Cochrane Library and Google Scholar were searched to December 2009. 63 studies measured attention, memory and judgment bias towards food stimuli in women with ED.
Stroop tasks had sufficient sample size for a meta-analyses and effects ranged from small to medium. Other studies of attention bias had variable effects (e.g. the Dot-Probe task, distracter tasks and Startle Eyeblink Modulation). A meta-analysis of memory bias studies in ED and RE yielded insignificant effect. Effect sizes for judgment bias ranged from negligible to large.
People with ED have greater attentional bias to food stimuli than healthy controls (HC). Evidence for a memory and judgment bias in ED is limited.
关于食物、体重和体型的适应不良认知会影响注意力、记忆和判断，可能与饮食失调行为有关。本文综述了饮食失调患者（ED）对食物刺激（文字、图片）的信息处理。
检索了 PubMed、Ovid、ScienceDirect、PsychInfo、Web of Science、Cochrane Library 和 Google Scholar，检索时间截至 2009 年 12 月。63 项研究测量了 ED 女性对食物刺激的注意力、记忆和判断偏差。
Stroop 任务的样本量足够进行荟萃分析，其效应从小到大不等。其他注意力偏差研究的效应（如点探测任务、分心任务和眨眼反射调制）各不相同。ED 和 RE 的记忆偏差研究的荟萃分析结果无显著影响。判断偏差的效应大小从微不足道到较大不等。
与健康对照组（HC）相比，ED 患者对食物刺激的注意力偏差更大。ED 中记忆和判断偏差的证据有限。
