“…Here we report on “E.C.”, a highly unusual case of color-gustatory synesthesia, in which color acts as the inducing stimulus for concurrent gustatory sensations. In the case of the slightly less unusual lexical-gustatory synesthesia, written or spoken words elicit taste sensations [2,3,4,5,6,7,8]. As color is frequently the concurrent [9], but rarely the inducer [10], our case, in which color is the inducer, is also untypical in this respect.…”

We investigated the effect of a sweetness blocker on the synesthetic taste experience of a rare color-gustatory synesthete, E.C., for whom specific colors elicit unique tastes. Blocking E.C.’s sweetness receptors while the tongue was otherwise unstimulated left other taste components of the synesthesia unaltered but initially reduced her synesthetic sweetness, which suggests a peripheral modulation of the synesthetic illusion.

“…Lexical-gustatory (LG) synesthesia is an intriguing neurological condition in which sounds induce phantom flavors (e.g., Ramachandra, 2016;Ward & Simner, 2003). People with LG synesthesia (known as LG synesthetes) experience floods of flavor in the mouth or intrusive food-related thoughts whenever they hear certain sounds, especially words.…”

“…Case reports (e.g., Gendle, 2007;Ramachandra, 2016;Richer, Beaufils, & Poirier, 2011;Ward & Simner, 2003) and small-group studies (e.g., Ward et al, 2005) have shown two ways in which LG synesthesia can be experienced. Synesthete J.I.W., for example, experiences LG synesthesia as if he were tasting veridical flavors in the mouth, with each word being like a droplet of taste on the tongue (Ward & Simner, 2003).…”

“…We developed our test from a consideration of previous methods. Participants have been validated as genuine cases of LG synesthesia in ten earlier studies (Bankieris & Simner, 2014;Colizoli, Murre, & Rouw, 2013;Gendle, 2007;Jones et al, 2011;Ramachandra, 2016;Richer et al, 2011;Simner & Haywood, 2009;Simner & Logie, 2007;Ward & Simner, 2003;Ward et al, 2005). All used the same validation method, known as a Btest of consistency.^In this test, researchers presents LG synesthetes with a list of words (e.g., 80 words in Simner & Haywood, 2009) and require them to verbally describe their synesthetic flavor for each word (e.g., Btable^= minced beef).…”

The MULTISENSE Test of Lexical–Gustatory Synaesthesia: An automated online diagnostic

Lexical-gustatory (LG) synesthesia is an intriguing neurological condition in which individuals experience phantom tastes when hearing, speaking, reading, or thinking about words. For example, the word Bsociety^might flood the mouth of an LG synesthete with the flavor of fried onion. The condition is usually verified in individuals by obtaining verbal descriptions of their word-flavor associations on more than one occasion, separated by several months. Their flavor associations are significantly more consistent over time than are those of controls (who are asked to invent associations by intuition and to recall them from memory). Although this test reliably dissociates synesthetes from nonsynesthetes, it suffers from practical and methodological limitations. Here we present a novel, automated, online consistency test, which can be administered in just 30 min in order to instantly and objectively verify LG synesthesia. We present data from two versions of our diagnostic test, in which synesthetes report their synesthetic flavors either from a hierarchical set of food categories (Exp. 1) or by specifying their basic component tastes (sweet, salty, bitter, etc.). We tested the largest sample of self-declared LG synesthetes studied to date and used receiver operating characteristic analysis to assess the discriminant power of our tests. Although both our methods discriminated synesthetes from controls, our second test (Exp. 2) has greater discriminatory power with a threshold cutoff. We suggest that our novel diagnostic for LG synesthesia has unprecedented benefits in its automated and objective scoring, its ease of use for participants and researchers, its short testing time, and its online platform.
