Exemplars of the PLWs Used in the Gender Identification Task (video) Cell Press Share Print E-Mail Loading video... Caption Each participant repetitively viewed seven PLWs, one at a time in random order, whose genders ranged in seven equal steps from feminine (0.45 SD) to masculine (0.45 SD), with 0 marking the approximate gender-neutral point individually adjusted in the absence of olfactory stimuli. Participants made a forced choice judgment on whether each PLW was a male or female walker. The movie shows five walking cycles. Credit Current Biology, Zhou et al.
