A field experiment was conducted in which a single male, a single female, or a male-female couple attempted to hitch rides at four different traffic locations, under conditions in which the hitchhikers either stared at or looked away from oncoming drivers. It was found that staring increased the probability of a driver stopping from .03 to .067 (z = 2.96, p = .003). The female was a more successful hitchhiker than either the male or the couple, (z = 2.215, p = .026; z = 1.861, p .063, respectively).
