Perception of body size was recorded for 63 university students (M age = 25.3 yr., 41 women) who estimated their own body size using three methods. Using the method of adjustment, subjects over- or underestimated their body size. A signal-detection analysis indicated that subjects were sensitive to detecting a 4% distortion in body size and that there was no systematic bias for reporting distortion as present or absent. Scores on the adaptive probit estimation task were significantly correlated with values for point of subjective equality and the size judgements with the method of adjustment. Over-all, this experiment demonstrated adaptive probit estimation as a reliable indicator of perceived body size, sensitivity in detecting size distortion, and response bias in making body-size judgements.
对63名大学生（平均年龄=25.3岁，41名女性）的身体大小感知进行了记录，这些学生使用三种方法估计自己的身体大小。使用调整法时，受试者高估或低估了自己的身体大小。信号检测分析表明，受试者对检测身体大小4%的失真很敏感，并且在报告失真是否存在方面没有系统偏差。自适应概率估计任务的得分与主观相等点的值以及调整法的大小判断显著相关。总体而言，该实验证明了自适应概率估计是感知身体大小、检测大小失真的敏感性以及做出身体大小判断时的反应偏差的可靠指标。
