Abstract

Abstract: Infants' knowledge of social categories, including gender‐typed characteristics, is a vital aspect of social cognitive development. In the current study, we examined 9‐ to 12‐month‐old infants' understanding of the categories "male" and "female" by testing for gender matching in voices or faces with biological motion depicted in point light displays (PLDs). Infants did not show voice–PLD gender matching spontaneously (Experiment 1) or after "training" with gender‐matching voice–PLD pairs (Experiment 2). In Experiment 3, however, infants were trained with gender‐matching face–PLD pairs and we found that patterns of visual attention to top regions of PLD stimuli during training predicted gender matching of female faces and PLDs. Prior to the end of the first postnatal year, therefore, infants may begin to identify gender in human walk motions, and perhaps form social categories from biological motion.
