Men and women holding hands: II. Whose hand is uppermost?

Sex differences in the way men and women hold hands were investigated in a series of six studies. Specifically, it was hypothesized that men would have the uppermost hand in male-female couples holding hands in public significantly more often than women. Also, the American couples observed in Study 1 were classified by height, those in Study 2 by age, those in Study 3 by hand preference, those in Study 4 by ethnic group, and those in Study 6 by sex of initiator of the handholding; the handholding couples in Study 5 were Japanese adults. A combined total of 15,008 handholding couples were observed in these six studies, and across differences in height, age, hand preference, ethnicity, culture, and sex of the initiator of handholding in public, men were significantly more likely than women to have the uppermost hand.
