Abstract
In several species, lateral position preferences have been observed in pair mates, mother-infant dyads, and during agonistic interactions. This research examined side preferences in human dyads in an observational study and survey. We observed 1236 male-female pairs walking in the UK and found a bias for males to walk on the right side of the pair, which did not depend on hand-holding, or walking during daylight or darkness. The survey measured side preferences in 798 participants (398 left-handed, 411 right-handed), from the UK (402) and USA (396). Participants chose a side to walk when walking with their partner, or alone, in various threatening/non-threatening scenes. Threat did not influence preference in walking couples, but males, when passing a threatening stranger, preferred the best combat side for their handedness. Country and handedness also influenced preferences. Left-handers preferred the left side and right-handers preferred the right side, and USA participants exhibited a more rightward preference than UK participants. The pattern of preference for each country was equivalent, showing independent influences of handedness and cultural learning. Overall, the results suggest that males and females prefer the side that allows their dominant hand to be on the outside of the dyad.
