Some people with autism display remarkable abilities. A few demonstrate skills far out of the ordinary. At a young age, when other children are drawing straight lines and scribbling, some children with autism are able to draw detailed, realistic pictures in three-dimensional perspective. Some toddlers who are autistic are so visually skilled that they can put complex jigsaw puzzles together. Many begin to read exceptionally early-sometimes even before they begin to speak. Some who have a keenly developed sense of hearing can play musical instruments they have never been taught, play a song accurately after hearing it once, or name any note they hear. Like the person played by Dustin Hoffman in the movie Rain Man, some people with autism can memorize entire television shows, pages of the phone book, or the scores of every major league baseball game for the past 20 years.
