Frederic Bartlett Sir Frederic Charles Bartlett FRS (20 October 1886 – 30 September 1969) was a British psychologist and the first professor of experimental psychology at the University of Cambridge. He was one of the forerunners of cognitive psychology. Bartlett considered most of his own work on cognitive psychology to be a study in social psychology, but he was also interested in anthropology, moral science, philosophy, and sociology. Bartlett proudly referred to himself as "a Cambridge Psychologist" because while he was at the University of Cambridge, settling for one type of psychology was not an option.
