The major purpose of this study was to examine bimodal coordination of featural stimuli in infancy. Specifically of interest was infant sensitivity to the auditory and visual combinations that characterize male and female stimulus configurations. A total of 27 male and 27 female subjects of 3, 6, and 9 months of age participated in the study. Infants were positioned approximately 12 inches from two television screens mounted 6 inches apart. Four 17-second simultaneous presentations of faces were made. Within each age group, one-third of the infants heard one of three auditory stimuli: either a male or female voice reciting a poem, or music. Two observers using a continuous event recorder noted the visual stimulus infants preferred. Results revealed that, in comparison with the other two age groups, 6-month-old infants looked significantly more at the male and female face during respective male and female voice conditions. In contrast, 3-month-old children looked significantly more at the female face regardless of the auditory condition. The 9-month-old infants exhibited a nonsignificant tendency to look at the opposite-sex face during male and female voice conditions. It was concluded that the study demonstrates the ability of infants, by the sixth month of life, to recognize male and female stimulus configurations across auditory and visual modalities. (RH)
