Studies have demonstrated the importance of body weight in physical attractiveness, where thinness in women and leanness and muscularity in men are judged to be attractive. However, most research has focused on young adults, while less has investigated whether attractiveness judgments of body weight change with age. Here, we compared young and older adults' preferences for body physique in a Chinese population using 3D human body models. We found that the attractiveness judgments of body physique vary with age, where older adults have weaker preference for thinness in both male and female bodies than did young adults. These results present novel evidence that preferences for body size alters with age. We propose that the variation in preference for thinness is likely due to the difference in resource availability between generations.

This preliminary study investigated whether individual differences in performance on a difficult social perception task (determining the sex of shape normalized, line drawn dynamic faces) are related to sex of observer, scores on an empathy quotient and scores on a systemizing quotient. Performance in the face perception task (N = 60) was above chance, indicating that participants could judge the sex of the degraded facial stimuli from dynamic information alone. There was a trend for women to be more accurate in their judgments of target sex than men, but regression analyses indicated that EQ scores alone predicted performance on the task. This study suggests that empathy may mediate sex differences in face perception abilities, and potentially other tasks in social perception.
