目的非语言动作线索（握紧拳头）传达有关演员意图的重要信息。神经性厌食症 (AN) 个体在从面部情感线索解读意图方面存在缺陷，但尚不清楚这种缺陷是否会延伸到解读身体运动线索的影响。方法我们检查了 AN 成年人 (n = 21) 或体重恢复≥12 个月的人 (WR;n = 20) 相对于健康对照 (HC;n = 23) 感知生物运动线索情感的能力。结果总体而言，AN 个体与 WR 或 HC 相比，在区分生物运动线索的影响方面表现出更大的缺陷。后续分析表明，患有 AN 的个体在五种情况中的两种方面存在差异，尤其是在区分悲伤时偏离标准数据最多，而相对于 WR 或 HC 更一致地区分愤怒。讨论这些发现的含义与 AN 的一些令人困惑的人际特征有关。 © 2012 Wiley periodicals, Inc. 版权所有（Int J Eat Disord 2013）
ObjectiveNonverbal motion cues (a clenched fist) convey essential information about the intentions of the actor. Individuals with anorexia nervosa (AN) have demonstrated impairment in deciphering intention from facial affective cues, but it is unknown whether such deficits extend to deciphering affect from body motion cues.MethodWe examined the capacities of adults with AN (n= 21) or those weight restored for ≥12 months (WR;n= 20) to perceive affect in biological motion cues relative to healthy controls (HC;n= 23).ResultsOverall, individuals with AN evidenced greater deficit in discriminating affect from biological motion cues than WR or HC. Follow‐up analyses showed that individuals with AN differed especially across two of the five conditions—deviating most from normative data when discriminating sadness and more consistently discriminating anger relative to WR or HC.DiscussionImplications of these findings are discussed in relation to some puzzling interpersonal features of AN. © 2012 by Wiley Periodicals, Inc.
