![]() ![]() Learning disabilities seem more common in synaesthetes. Synaesthetic experience is very individual for example, among people who see coloured sounds there is no specific colour for each sound from person to person. Probably, the reported low incidence of synaesthesia in autistic people can be accounted for by the fact that it is not easily detected in the autistic population because many autistic children with synaesthesia don’t realise that other people cannot hear sounds while seeing colours. Though the fact that synaesthesia does occur in autistic people is recognised, it is considered to be rare. The research of prevalence shows that 2-5% of the population have synaesthesia (Simner et al. Cognitive synaesthesia combines sensory (usually colour) and semantic triggers – letters, words and numbers - when letters/words/numbers are heard or read they are experienced as colours or numbers are experienced as shapes or forms.Īnother variation of the cognitive synaesthesia is conceptual synaesthesia, when abstract concepts (for example, units of time, mathematical operations) are perceived as shapes or colours. When stimulation of one sensory area triggers simultaneous sensations in several other senses, e.g. a child may experience the taste of the sound while simultaneously seeing the colour and experiencing tickling sensation on the skin.Īnother major distinction is made between sensory synaesthesia and cognitive synaesthesia.

When stimulation of one sensory area triggers the perception in a second area. Different variations and forms of synaesthesia.Īccording to the number of senses involved, synaesthesia can be of two types: 1. Too much noise creates visual chaos – making it impossible to interpret their environment and comprehend what is going on around them. What is even more interesting, the sound can be both felt on their skin and seen by their eyes simultaneously. But there are no strict rules as the experiences, interpretation and response change at different times. Often the skin sensation comes from sounds other people cannot hear. Lucy Blackman (2001) calls this phenomenon ‘sound-feeling’. Some autistic individuals experience ‘being touched’ by sounds, in other words, certain sounds are more felt than seen. Alternatively, when somebody looks (or stares) at them directly, they feel it on the skin. Quite common in autistic pople is the form of synaesthesia that produces tactile sensations without the individual being physically touched, for example, looking at something can bring a tactile experience. “Wednesdays are always blue, like the number nine or the sound of loud voices arguing…Tuesdays are a warm colour while Thursdays are fuzzy” Olga shares her experience and insight into synaesthesia in autistic people.Īlthough not specific to autism, synaesthesia seems to be quite common among autistic individuals.
