Rain Man
The subject of one of the most famous case studies in the history of psychology, Kim Peek was able to simultaneously read two pages of a book—one with each eye—and memorize nearly all the information it contained. Like the movie character he inspired (“Raymond Babbitt” in the movie Rain Man), Peek had extraordinary intellectual abilities but a low IQ (Brogaard & Marlow, 2012, December 11). Case studies are often used to explore rare psychological conditions relating to cognition, personality, and behavior.
