The Bias toward the Right Side of Others Is Stronger for Hands than for Feet

As shown by a series of previous studies, ambiguous human bodies performing unimanual or unipedal actions tend to be perceived more frequently as right-handed right-footed rather than left-handed left-footed, which indicates perceptual and attentional bias toward the right side others’ body. However, none such studies assessed whether relative strength differs between upper lower limbs. Indeed, given that prevalence right-handedness is slightly larger right-footedness, hands provide information feet regards both communicative aggressive acts, it plausible should stronger for hand foot. We performed three experiments in each participants had indicate rotating direction (revealing handedness/footedness) figures with either one limb (arm leg) two limbs (one arm contralateral extended. The hypothesized advantage over foot was found second third experiment.
