Abstract
A sound presented in close temporal proximity to a visual stimulus can alter the perceived temporal occurrence of that visual stimulus[1] (i.e. temporal ventriloquism. The conditions under which this crossmodal interaction occurs (spatial and temporal disparity between sound and light, grouping of the sound), and its neural consequences[2] (ERPs) will be discussed. Our results challenge the commonly held view that similarity in space and time are necessary and sufficient conditions for crossmodal interactions to occur[3].
