The primary purpose of the study was to explore, experimentally, the common clinical observation that anorexics are highly perfectionistic.
Extremely weight-concerned and control college student subjects (as defined by scores on the Eating Attitudes Test [EAT]) were assigned high or low goals or they selected their own goals in a performance situation. After a series of 10 trials on which personal performance goals were measured, subjects in the high and low goal groups received false feedback indicating success or failure, and mood was measured.
High (vs. low) EAT subjects were more likely to persist in accepting an unrealistically high imposed goal, set lower personal goals in the absence of external standards, and were more strongly affected by the feedback.
Many characteristics of anorexics (including pursuit of thinness) can be accounted for in terms of their strong need for social approval and conformity to external standards.
本研究的主要目的是通过实验探索厌食症患者高度追求完美这一常见临床观察现象。
根据饮食态度测试（EAT）得分定义，将极度关注体重的大学生受试者和对照组大学生受试者分配高目标或低目标，或者让他们在表现情境中自行选择目标。在进行了一系列10次测量个人表现目标的试验后，高目标组和低目标组的受试者收到表明成功或失败的虚假反馈，并测量其情绪。
EAT得分高（与得分低相比）的受试者更有可能坚持接受不切实际的高设定目标，在没有外部标准的情况下设定较低的个人目标，并且更容易受到反馈的影响。
厌食症患者的许多特征（包括追求瘦身）可以从他们对社会认可的强烈需求以及对外部标准的遵循方面来解释。
