Abstract: | The role of spatial co-location between sight and sound in infants' cross-modal learning was examined in three experiments. Four-and 6-month-old infants were familiarized with a toy and an accompanying soundtrack. Across conditions, spatial congruity between sight and sound was varied. Following familiarization, infants were tested to determine under which conditions they learned to associate the toy with the sound. Results indicated age-related differences in how discrepant in location a sight and sound could be for infants to form a cross-modal association based on the amodal invariant of co-location. Specifically, 4-month-olds formed cross-modal associations under conditions of less precise co-location than did 6-month-olds. Parallel improvements in infants' sound localization abilities across this age span are likely a contributing factor to the observed developmental trend in cross-modal learning. |
