We examined the effect of body norms on ideal and current body size perception. In Study One, female participants were randomly assigned to one of three experimental conditions: (1) a thinner body norm, (2) a heavier body norm, or (3) no body norm. Body norms were manipulated by indicating a bogus "population average," and current and ideal body size perception were subsequently measured using a body silhouettes measure. Women had a thinner ideal body size in the thinner norm condition than in the heavier norm condition. Study Two replicated these results, but in a sample of young men and with regards to muscularity rather than thinness. Men had a more muscular ideal body size in the more muscular norm condition than in the less muscular norm condition. Current body size perception was also influenced by body norms, but only for women and after controlling for BMI.
我们研究了体型规范对理想体型和当前体型感知的影响。在研究一中，女性参与者被随机分配到以下三种实验条件之一：（1）更瘦的体型规范，（2）更胖的体型规范，或（3）无体型规范。通过暗示一个虚假的“人群平均值”来操纵体型规范，然后使用身体轮廓测量法来测量当前和理想的体型感知。与更胖的体型规范相比，在更瘦的体型规范下，女性的理想体型更瘦。研究二复制了这些结果，但样本是年轻男性，且涉及的是肌肉发达程度而非瘦度。在更发达的体型规范下，男性的理想体型更有肌肉，而在不太发达的体型规范下则不然。体型规范也会影响当前的体型感知，但仅对女性有影响，并且需要在控制 BMI 后进行。
