目的：本研究探讨神经性厌食症患者的执行功能，如抽象、策略使用和反应灵活性（集中注意力）。其目的是强调神经心理功能与饮食方式、身体形象和身体状态的病理程度之间的任何相关性。方法：对20名神经性厌食症患者（AN-R）和20名对照组进行改良Stroop测验、Wisconsin卡片分类测验、体型问卷和进食障碍量表-2。结果：AN-R受试者表现出非特异性的注意力偏差，以及抽象思维和思维灵活性方面的障碍，与强迫症患者相似。身体意象的干扰与额叶的改变有直接的关系。讨论：这一证据表明，在an - r受试者中，身体形象的干扰可能与抽象和批判能力的改变以及强迫性额叶功能有关。(C) 2002， Wiley期刊公司
Objective: This study deals with executive functions such as abstraction, use of strategy, and response flexibility (focused attention) seen in patients with anorexia nervosa. The aim was to highlight any correlation between neuropsychological functioning and the degree of pathology for food style, body image, and physical state. Method: A modified Stroop test, Wisconsin Card Sorting test, Body Shape Questionnaire, and Eating Disorder Inventory-2 were administered to 20 anorexia nervosa restricters (AN-R) and 20 control subjects. Results: The AN-R subjects showed nonspecific attentional biases, in addition to disorders regarding abstraction and flexibility of thought, similar to those seen in patients with obsessive-compulsive disorder. The disturbance of body image showed a direct correlation to frontal alterations. Discussion: This evidence suggested that in the AN-R subjects the disturbances of body image might be linked to the alterations of abstraction and critical abilities and with an obsessive frontal functioning.
