Abstract

Young infants perceive an object’s trajectory as continuous across occlusion provided the temporal or spatial gap in perception is small. In three experiments involving 72 participants we investigated the effects of different forms of auditory information on 4-month-olds’ perception of trajectory continuity. Provision of dynamic auditory information about the object’s trajectory enhanced perception of trajectory continuity. However, a smaller positive effect was also obtained when the sound was continuous but provided no information about the object’s location. Finally, providing discontinuous auditory information or auditory information that was dislocated relative to vision had negative effects on trajectory perception. These results are discussed relative to the intersensory redundancy hypothesis and emphasise the need to take an intersensory approach to infant perception.
