Speeded responses to audiovisual signal changes result from bimodal integration Psychophysiology, Vol. 35, No. 6. (November 1998), pp. 755-759 by Erich Schröger, Andreas Widmann
    abstract = {Integration of auditory and visual information was studied in humans detecting targets (i.e., location changes of the auditory, the visual, or both parts of a repetitively presented audiovisual stimulus). Behavioral results suggest that the time advantage to bimodal compared with unimodal targets was due to combined rather than separate processing of the auditory and the visual target information. Event-related brain potential results revealed strong audiovisual interactions supporting interactive and not independent coactivation models. The time course of this interaction suggests that the audiovisual integration occurred after low-level, sensory processing but well before the execution of the motor response.},

Reactions to cross-sensory stimuli can be faster than the fastest reaction to any one of the constituent uni-sensory stimuli (as would be predicted by the race model.).

The race model of multi-sensory integration assumes that the reaction to a multi-sensory stimulus is as fast as the fastest reaction any of the individual stimuli.
