摘要

While people might endorse tolerance, social/environmental biases can remain operative and drive action in an unconscious manner. Herein, we investigated whether the criteria for judging others’ body shapes as “fat” or “thin” change with the degree of satiety. Nine females participated in the present study. The participants judged nine women’s figures as fat or skinny on a computer monitor in two conditions (Fasting and Satiety). Each figure ranged in body mass index (BMI) from 18.3 to 45.4 (i.e., 18.3, 19.3, 20.9, 23.1, 26.2, 29.9, 34.3, 38.6, and 45.4). Parameter estimates showed that a one-unit change in condition (Fasting vs. Satiety) resulted in a 20.0% greater probability of switching from “fat” to “thin” (SE = 0.056, z = 3.631, p < 0.0001). Notably, figures judged as “fat” in the fasting condition were judged as “thin” in the satiety condition. Thus, we concluded that satiety relaxes criteria for judging the thinness of others’ body shapes.
