It is important to specify the kinds of information available that permits the holistic and unified perception of an audio-visual event. For example, for hammer banging, ball bounding, person walking, or hands clapping, each has several types of information (tempo, rhythm, synchrony) that allow perceivers to detect a united auditory and visual event. The degree of spatial mis-match, and the amount of temporal mismatch (for non-corresponding events), as well as temporal invariants such as tempo, rhythm, synchrony, and intensity, must all be carefully operationalized and manipulated to see how these influence visual or auditory bias in spatial lateralization. It would be of interest to see the effects of spatial mismatch on perception of face-voice coherence (since temporal mismatch alone is so salient) and because social stimuli may be differently processed than non-social objects/events. David J. Lewkowicz has published work on infants’ perception of audio-visual compounds and the early emergence of multisensory perception and auditory-visual matching in the absence of spatial cues.
