Using similar shapes to those in the original experiment, but changing the names of the invented terms slightly, they found that an astonishing 95 per cent of people labelled the spiky object as "kiki" and the curvy one as "bouba". One possible explanation is that this might be down to the shapes of the lips as we form the vowels in these words; in "bouba" they are more curved than in "kiki".

"A new hypothesis proposes that savantism arises due to a combination of autism and another condition, synaesthesia. "

"People with synaesthesia experience odd sensations that make it seem as though their neural wires are crossed. A certain word might always come served with the same particular taste, or a letter or numeral might reliably evoke the same particular colour. But an emerging view among experts is that synaesthesia is grounded in concepts, not crossed senses."

Dutch psychologists now report that different types of synaesthetic experiences are associated with different brain mechanisms, providing a rare glimpse into the workings of the black box.

For millennia, philosophers have mused over the nature of perception, how closely it mirrors “reality” and whether different people might, quite without knowing it, subjectively perceive the world in very different ways. We might agree that an apple is “red”, but is the quality of your experience of its redness the same as mine? This has seemed an almost impossible nut to crack, but the fascinating condition of synesthesia provides a stark example where the quality of subjective experience is very definitively and demonstrably different. This may be due to genetic variants which affect the functional segregation of specialized circuits in the brain which makes synesthesia even more interesting.

Dr. Richard Cytowic is one of the leading researchers of synesthesia, a condition in which two normally separated sensations - such as sight and sound, or touch and taste - occur at the same time. As a result, a synesthetic person might experience the taste of a dish on her fingertips, or be convinced that the letter X is a vibrant turquoise. (Scientific American)

While synaesthesia often involves letters or sounds triggering the perception of specific colours, celebrated brain scientist V.S. Ramachandran and his colleague David Brang have identified two young women who experience strong emotions when they feel the touch of certain fabrics or textures.

"A new study published online in Brain searched for letter-colour synaesthetes in 6-8 year old children and found not only are they relatively common, but that the condition changes as the children grow." (Mind Hacks)

Artist and researcher Mitchell Whitelaw wrote an interesting and in-depth article on the links between audio-visual fusion art and synaesthesia for the Senses and Society journal. Whitelaw has just put the piece online, has illustrated it with embedded videos of some of the stunning pieces he references, but also discusses the neuroscience of synaesthesia with considerable care and insight.

Wired Science has an interesting preview of an upcoming study that used hypnosis to induce colour-number synaesthesia in highly hypnotisable participants. (Mind Hacks)
