Savantism is typically associated with autism to the point where many people assume that having a stand-out exceptional ability is present in everyone with the diagnosis.
This is not the case and although many people with autism-spectrum conditions will have a special interest, only about 10% will have what autism researchers Francesca Happ√© and Uta Frith call ‘the beautiful otherness of the autistic mind’.
Perhaps the most famous artist with autism is Stephen Wiltshire who can create stunningly vivid landscape paintings from a barely more than a single glance.
However, my favourite such artist is Jessica Park who paints the most striking paintings of buildings and architectural features but in the most inventively colourful way.
The New Scientist gallery is interesting take on the area as each picture has been selected to illustrate something about the psychology of savant abilities.
