Synaesthesia“A condition in which a sensory experience

normally associated with modality occurs when another modality is stimulated to certain extent such as cross modality experiences are perfectly normal; e.g. low-pitched tones gives sensations of softness or fullness while high-pitched tones feel brittle and sharp, the color blue feels cold while red feels warm.”

“However, the term is usually restricted to the unusual cases in which regular and vivid cross-modality experiences occur.”

In other words. . . . .

Synaesthesia is where peoples senses can get a bit mixed up. It is like an extra sense.

There are at least sixty- one types of Synaestheasia, two–sensory and multiple-sensory.

Two-Sensory SyanesthesiaThis is where two senses cross. It can be

undirectioal e.g. a word produces a colour, or bi-directional e.g. a word can produce both a colour and a sound. A smell produces the perception of a colour ->

Coloured-OlfactionA taste produces the perception of colour ->

Coloured-GustationA sound produces the perception of colour ->

Coloured-Hearing or Chromaesthesia

Multiple-Sensory SynaesthesiaThe experience of numbers that have their

own colours -> Coloured-NumbersThe experience of letters as colours ->

Coloured LettersThe experience of colours when the

individual hears words -> Coloured-Graphemes

The experience of numbers as shapes -> Shaped-Numbers

Coloured-Letters/Numbers

Aliens in the FamilyWritten by Jamie Ward, and published 2008.“People with synesthesia experience the

ordinary world in extraordinary ways.”Most synesthetes don’t realise their

condition, just as in the case of Debbie she did not discover she had synesthesia until her mid-twenties.

Sometimes synesthesia rules a persons life without them ever realising it; they will often name their children to fit their synesthesia and choose their partners on this basis.

“The fact that synesthesia runs in families doesn’t automatically make it genetic.” Although, there is scientific evidence of a genetic link to synesthesia.

Even though synesthisa runs in families it doesn’t mean all family members have the same form.

In the case of the identical twins Mary and Jacqueline, they had similar types of synesthesia but saw different colours.E.g Mary sees “a” as green and Jacqueline sees

it as red.Yet again they didn’t realise they had

synesthesia until they were in their early twenties.

Today’s LectureThe most common forms of synesthesia, and

the ones we will be looking at are:Grapheme -> colour synesthesia -> multiple-

sensoryChromaesthesia -> coloured hearing -> two-

sensory Coloured Gustation -> Taste as a colour ->

two-sensory

GraphemeThis is where the individual experiences

colour when they hear words.

ChromaesthesiaThis is where an non visual stimuli evokes the

perception of a colour.Such as seeing colour as you hear music.

Coloured GustationWhen some synesthetes eat the food evokes

the perception of colour.

This is one of the tests for synesthesia we came across:
