TY - JOUR ID - citeulike:5909475 L3 - citeulike-article-id:5909475 N2 - Using the preferential-looking procedure infants 5, 7, and 9 months of age were presented two videoimages side by side on separate monitors accompanied by a soundtrack that matched one of the images. Each infant was presented: (1) a stationary drum-beating toy paired with the same toy approaching and receding in depth, to assess infants' recognition both that changing sound amplitude is a property of an object that is moving in space and that constancy in amplitude is a property of a stationary object; (2) a drum-beating toy moving horizontally paired with one approaching and receding in depth, to assess infants' recognition that systematic increases and decreases in amplitude accompany object movement in a particular dimension, namely depth; and (3) two identical toys alternately approaching and receding in depth but out of phase (i.e., one approaching while the other is receding), to assess infants' recognition that increases and decreases in amplitude accompany a particular type of object movement in depth. Measures of mean duration of looking time indicated that the 5-month-olds looked reliably to the correct videoimage only for the stationary toy paired with the constant amplitude sound. The 7-month-olds recognized that changes in amplitude accompany object movement in depth but did not coordinate auditory with visual depth information as well as older infants. The 9-month-olds looked reliably to the correct videoimages in all conditions. Possible contributing factors to these developmental trends in performance are discussed.
