“…After the seminal work by McGurk and MacDonald (1976) that showed a cross‐modal interaction between auditory and visual processing, cross‐modal interaction and synergism have been reported across a number of sensory combinations as between the auditory system and other sensory modalities such as vision (Chanauria et al, 2019; Ethofer et al, 2006; Kayser et al, 2010; Lovelace et al, 2003; McDonald et al, 2000; McDonald & Ward, 2000; Noesselt et al, 2010; Satoh et al, 2015; Shams et al, 2000; Tivadar et al, 2018; Watanabe & Shimojo, 2001), olfaction (Castiello et al, 2006; La Buissonnière‐Ariza et al, 2012) and gustation (Carvalho et al, 2015, 2016; Knoferle & Spence, 2012; Lin et al, 2019; North, 2012; Yan & Dando, 2015). Similarly, several studies report cross‐modal interaction or enhancement between visual stimulation and olfaction (Zellner & Kautz, 1990; Zellner & Whitten, 1999; Gottfried & Dolan, 2003; Michael et al, 2003; Koza et al, 2005; Demattè et al, 2006, Demattè et al, 2009; Seo et al, 2010; Dong & Jacob, 2016) and gustation (Delwiche, 2012; Spence, 2019; Van Beilen et al, 2011). Synergism due to combination of olfactory and gustatory cues is not only constantly experienced almost with each meal or snack but has also been documented by several studies (Djordjevic et al, 2004; Welge‐Lüssen et al, 2005) including the case of ‘umami’, the fifth taste due to the conjunctive effects of monosodium glutamate (MSG) and olfactory cues from foodstuffs resulting in a synergistic enhancement of taste (McCabe & Rolls, 2007; Rolls, 2009).…”
