Intersensory facilitation occurs if the response to a stimulus, or a set of stimuli, from one sensory modality is in some way furthered by the concurrent stimulation of one or more other sensory modalities. The facilitation may manifest itself as: (1) a speed-up of reaction time, (2) a lowering of the sensory threshold for detection or discrimination of stimuli, or (3) an increase in the rate of recognition, identification, or classification of stimuli, or in particular stimulus qualities like loudness or brightness. Intersensory facilitation is part of a more general class of crossmodal phenomena including  intersensory suppression and crossmodal illusions like  ventriloquism.

Theoretical Background

Research on intersensory interaction and its underlying multisensory integration mechanisms has seen a tremendous increase over the last 20 years, spearheaded by neurophysiologists...
