“…There is growing evidence for cross-modal synergism when stimulation from one modality is combined with that from another. After the seminal work by McGurk and MacDonald, 1976) that showed a cross-modal interaction between auditory and visual processing, cross-modal modulation and synergism have been reported across a number of sensory combinations such as between vision and audition (McDonald and Ward, 2000; Watanabe and Shimojo, 2001; Kayser et al, 2009), vision and olfaction (Zellner and Kautz, 1990; Zellner and Whitten, 1999; Koza et al, 2005; Dematte et al, 2009), vision and touch (Kennett et al, 2001; Ro et al, 2004; Gori et al, 2011), olfaction and audition (La Buisonniere-Ariza et al, 2012), somatosensation and audition, as well as audition and gustation (North, 2012). …”
