(1926–93). Though born in Birmingham, the distinguished experimental psychologist Donald Broadbent identified himself, from ancestry and upbringing, as Welsh. Having flown in the RAF, he was drawn to problems of legibility of instruments and confusions of controls. These led him to develop pioneering ideas on information transmission in the nervous system and the role of selective attention. As director of the MRC Applied Psychology Laboratory, he was able to combine work on practical problems while developing theoretical insights of lasting significance, especially in his book Perception and Communication (1958), which introduces his notion of limited-capacity information channels and perceptual filters.
