Grapheme-color synesthesia How someone with grapheme-color synesthesia might perceive (not "see") certain letters and numbers Grapheme-color synesthesia or colored grapheme synesthesia is a form of synesthesia in which an individual's perception of numerals and letters is associated with the experience of colors. Another less-used name is "colour-graphemic" synesthesia (and also occasionally "colour-grapheme") It includes letter-colour, word-colour and number-colour (digit-colour) People with this type of synesthesia involuntarily associate certain colours to graphemes (letters, numbers and other written symbols such as punctuation marks or characters in languages with non. The apparently most common form (with a 64.4% prevalence among synesthetes) is grapheme-color synesthesia, in which achromatic letters or digits automatically trigger an idiosyncratic color perceptual experience (e.g., the letter 'm' induces blue color percepts) [25, 26] (Fig.
1 [27]). Color synesthesia is a neurological phenomenon where individuals experience colors in response to non-visual stimuli. For these "color synesthetes," the world is painted with hues triggered by sounds, tastes, emotions, or even abstract concepts like time and mathematics.
This unique perceptual experience is involuntary and consistent over time. A synesthete who sees the letter 'A' as. Color synesthesia is a neurological phenomenon where an individual's senses are involuntarily linked.
This connection causes stimulation in one sensory or cognitive pathway to automatically trigger experiences in a second, unrelated sense. For people with color synesthesia, this often means seeing colors when hearing sounds, reading letters or numbers, or even thinking about certain concepts. The prevalence of color synesthesia is unknown.
Estimates range from 1 in 200 to 1 in 250,000 [13, 14]. Some speculate that color synesthesia may be present in more than 4 % of the population [5]. One of the best-known forms of color synesthesia is grapheme-color synesthesia, in which numbers or letters are seen as colored.
Grapheme-color synesthesia is one of the most common and well-studied forms, where individuals associate graphemes-the fundamental units of a writing system, like letters and numerals. A person experiencing synesthesia may associate certain letters and numbers with certain colors. Most synesthetes see characters just as others do (in whichever color actually displayed) but they may simultaneously perceive colors as associated with or evoked by each one.
Synesthesia (American English) or synaesthesia (British English) is a perceptual phenomenon in which stimulation of one. Their study of grapheme-color synesthetes (who experience letters, digits, or entire words in color) found that processing centers for letters and numbers happen to be right next to the processing center for colors in the human brain. A relatively common and well-studied type is grapheme-color synesthesia, defined as the consistent experience of color when viewing, hearing and thinking about letters, words and numbers.
We describe our method for investigating to what extent synesthetic associations between letters and colors can be learned by reading in color in nonsynesthetes.
