Lexical-gustatory synesthesia : ウィキペディア英語版 | Lexical-gustatory synesthesia Lexical-gustatory synesthesia is a rare form of synesthesia in which spoken and written language (as well as some colors and emotions) causes individuals to experience an automatic and highly consistent taste/smell. The taste is often experienced as a complex mixture of both temperature and texture. For example, in a particular synaesthete, JIW, the word ''jail'' would taste of cold, hard bacon. Synesthetic tastes are evoked by an inducer/concurrent complex. The inducer is the stimulus that activates the sensation and the taste experience is the concurrent. ==Experimental studies== There are many scientific standards in use to determine if a person actually has the genuine neurological condition of lexical-gustatory synesthesia. Scientists check for the behavioral hallmark of a significantly higher retest consistency after at least a year compared to control groups. Another scientific standard method to determine the legitimacy of ones synesthesia is to use Functional magnetic resonance imaging or functional MRI (fMRI) to determine which areas of the brain are active during the scan. 〔〔 A final method utilized by the prominent neuroscientist, V.S. Ramachandran, is the galvanic skin response (GSR). The GSR measures any fluctuations in the electrical resistance of skin. A high GSR could indicate that a person might be lying about their synesthesia condition. No GSR indicates that a person would be telling the truth about their synesthesia.
