This study investigated perceptual styles in anorexia nervosa (AN) and bulimia nervosa (BN) using a perceptual set task. We hypothesised that, consistent with personality style research. AN patients might be more rigid in style than those with BN or no eating disorder. We found that once an illusion had been established, participants with AN and BN showed more illusions than non-ED women. However, while AN patients responded rigidly, giving the same response repeatedly, BN patients were more likely to change their responses. The study suggests interesting differences to be followed up in future research. Differences in rigid and fluctuating perceptual styles may have implications for understanding the phenomenology of eating disorders, and have implications for treatment.
本研究使用一种知觉定势任务调查了神经性厌食症（AN）和神经性贪食症（BN）中的知觉风格。我们假设，与人格风格研究一致，AN患者在风格上可能比BN患者或无进食障碍者更为刻板。我们发现，一旦一种错觉被确立，AN和BN的参与者比无进食障碍的女性表现出更多错觉。然而，虽然AN患者反应刻板，反复给出相同答案，但BN患者更有可能改变他们的答案。该研究表明在未来研究中有一些有趣的差异有待跟进。刻板和波动的知觉风格差异可能对理解进食障碍的现象学有影响，并且对治疗也有影响。
