Beskrivelse

Synaesthesia is a condition describing a small percentage of the neurotypical observers who experience an additional concurrent following an inducer stimulus. Some experience that weekdays or letters have a specific colour, or that a number also relate to a particular place in space. Traditionally, it is believed that synaesthesia has a genetic component and may be the result of either increased cross-wiring or decreased lateral inhibition in certain areas of the brain. Some researchers have previously argued for an account suggesting that expertise and previous knowledge could establish synaesthesia in an observer (e.g. through the exposure to coloured refrigerator magnets during childhood). Initially these studies were somewhat controversial, but more and more research seem to support that experience is a key component in forming the synaesthetic association. First modulation of attentional parameters in colour-grapheme synaesthetes are modulated similar to the modulations that occur through expertise. Secondly, a few studies have managed to train non-synaesthetes to have synaesthesia, and thirdly, colour-grapheme synaesthesia develops gradually over time.
