While pursuing their special interest (see the previous section), an autistic person is likely to develop an exceptional knowledge or grasp of their favoured topic and so become an expert. A minority of autistic people show truly exceptional talents, which typically appear in early childhood, often without prior learning or practice.
For instance, Stephen Wiltshire did not speak until he was 5 years old, and was diagnosed with autism. But he showed an outstanding talent for drawing from an early age, and without being taught. Ever since then he has been drawing complex cityscapes such as Canary Wharf, producing impressive and astonishingly accurate works after just a few minutes studying the subject matter.

Such exceptional talent, surpassing that of most neurotypical people and coupled with fairly profound difficulties, is often known as savant talent. As in these examples, it often involves visual art or music, though savant talent may also involve domains such as calculation, as portrayed in the film Rain Man. Note that Dustin Hoffman’s character Raymond had difficulty with everyday transactions despite his specific calculating skills.
