Sir Frederic Bartlett

Born 20 Oct 1886; died 30 Sep 1969 at age 82.Sir Frederic Charles Bartlett was an English psychologist who was Britain's most outstanding cognitive psychologist between the World Wars. He wrote on practical (ergonomic) problems in applied psychology, but is best-known for his pioneering cognitive approach to understanding human memory. In forming one of the earliest models of memory, Bartlett observed that in remembering stories or events there is a tendency for distortions to occur. In his most famous experiment, Bartlett had subjects read a folk tale, tested their recall several times, and studied their changing recountings of the story. People tend to remember what they regard as most important and recall what would have been expected rather than what actually occurred.«
