Literally, the word synesthesia means ‘joined
sensation’ (Greek: syn = union + aisthesis
= to perceive).
Synesthesia
is a condition where the
perception of an external object
or experience, triggers a
perceptual experience in additional
sensory modalities. For example,
the visual perception of
an object may also trigger
an auditory sensation, or the
auditory perception of a sound
may also
trigger a tactual sensation.
At
its most basic, synesthesia
describes multi-sensory experience.
Specifically, synesthesia
describes the phenomenon
of experiencing visual, auditory,
tactual stimuli as inter-linked.
For those with synesthetic
sensitivity, a triangle is perceived not
only
as a shape but may simultaneously
be experienced as a
sound (eg. a bell) or a colour
(eg. red).
