The purpose of this study is to examine set-shifting, central coherence, and decision making in women currently ill with anorexia nervosa (AN), women recovered from AN, and healthy control women. We aim to test whether these neuropsychological weaknesses persist after recovery, and explore relations between the impairments
Compared to control women, ill and recovered women showed poor set-shifting and decision making. There were strong correlations between set-shifting and central coherence in the ill and recovered women. Decision making did not correlate with the other measures.
The present findings suggest that impaired set-shifting and decision making are stable traits in women with AN. Because individual differences within these groups were large, a rigid thinking style is only present in a (sub)population of ill and recovered women. Decision-making performance is not related to a rigid thinking style, but further research in this area is warranted.
本研究旨在探讨目前患有神经性厌食症（AN）的女性、已从 AN 中康复的女性和健康对照组女性的转换能力、中心连贯和决策能力。我们旨在测试这些神经心理缺陷是否在康复后仍然存在，并探讨这些缺陷之间的关系。
与对照组女性相比，患病和康复后的女性在转换能力和决策能力上表现较差。患病和康复后的女性的转换能力和中心连贯之间存在很强的相关性。决策能力与其他测量指标之间没有相关性。
本研究结果表明，转换能力和决策能力受损是 AN 女性的稳定特征。由于这些组内的个体差异较大，刻板思维方式仅存在于患病和康复女性的（亚）人群中。决策能力与刻板思维方式无关，但需要在该领域进一步研究。
