In visual synesthesia, the concurrent may be projected out into space and experienced as located in the visual scene outside the subjectвЂ™s mind, or it may be merely imagistically or semantically associated with the inducer 4). The trigger of the experience is called вЂњthe inducer,вЂќ whereas the additional experience to which it gives rise is called вЂњthe concurrentвЂќ 3). For example, seeing the number 7 may lead to an experience of navy blue, hearing the word вЂњblissвЂќ may flood the mouth with the flavor of bread soaked in tomato soup and hearing the key of C minor may elicit a bright purple spiral radiating from the center of the visual field. In some cases, this means that a synesthete might experience a sensation in one of the 5 senses (hearing, vision, taste, touch, smell) that is triggered by a different sense (e.g., sounds trigger tastes, smells trigger colors etc.). People with synesthesia experience unusual sensations (e.g., of color, of taste) when doing things that wouldnвЂ™t usually trigger those sensations for non-synesthetic people. Likewise, perception of a form (e.g., a letter) may induce an unusual perception in the same modality (e.g. Synesthesia is a perceptual condition of mixed sensations: a stimulus in one sensory modality (e.g., hearing) involuntarily elicits a sensation/experience in another modality (e.g. The word вЂњsynesthesiaвЂќ comes directly from the Greek (syn-) вЂњunionвЂќ, and (aВsthesis) вЂњsensationвЂќ, thus meaning something akin to вЂњa union of the sensesвЂќ. Synesthesia is an extraordinary way of perceiving the world, involving experiences of connections between seemingly unrelated sensations, images or thoughts 1). Can synesthesia occur for taste and smell?.Is it possible for a synesthete to have more than one type of synesthesia?.What is the most common type of synesthesia?.How many different types of synesthesia are there?.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.ДЄutomated consistency test LexicalвЂ“gustatory synesthesia Synesthesia Taste. 2) has greater discriminatory power with a threshold cutoff. Although both our methods discriminated synesthetes from controls, our second test (Exp. 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. 1) or by specifying their basic component tastes (sweet, salty, bitter, etc.). 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. 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. Although this test reliably dissociates synesthetes from nonsynesthetes, it suffers from practical and methodological limitations. 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). 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. For example, the word 'society' might flood the mouth of an LG synesthete with the flavor of fried onion. Lexical-gustatory (LG) synesthesia is an intriguing neurological condition in which individuals experience phantom tastes when hearing, speaking, reading, or thinking about words.
