ABSTRACT
Differences between the sexes in smiling and sensitivity to nonverbal cues were picked as demonstration cases for this exercise. Hall concluded that "although nonverbal sex differences are not large in absolute magnitude, they are as large or larger than those found for most of the psychological variables that have been summarized so far". In one extensive analysis, Rosenthal, Hall, DiMatteo, Rogers, and Archer compared male and female scores on the Profile of Nonverbal Sensitivity in 133 samples; participants from third grade through adulthood were included but analyses demonstrated no interaction of age and sex. Thus, extraordinary consistency is seen in the size of the sex difference for sensitivity to nonverbal cues. However, the range was much greater than in the cognitive domain; the effects for assertiveness, masculinity, femininity, and tendermindedness were comparable to those for smiling and nonver- bal sensitivity.
