An experiment was performed to show that infants perceive auditory and visual stimuli within a common space and that they perceive the sound as an attribute of the visual object. Subjects were 22 infants aged 3 to 5 months. Each infant was presented with a toy that moved in a small arc from side to side of a small window at the rate of one arc per second. The back-and-fourth movements occurred in synchrony with a chime. The sound was wired either to come from the front window where the toy was located or from 90 degrees to the side behind a cloth. Two dependent measures were recorded: (1) limb and body movement, and (2) visual orientation to the left or right. Infants showed increases in agitated limb and body movement when presented with the chime spatially dislocated from its temporally synchronous visual source (the toy). Agitation was not shown when the chime and the toy were presented together in space. Infants who demonstrated adequate processing of the auditory information through accurate orientation behavior were most likely to show increased agitation. (Author/BRT)
