Dr Norman F. Dixon, M.B.E., Fellow of the British Psychological Society, was Professor Emeritus of Psychology at University College London. After ten years' commission in the Royal Engineers, during which time he was wounded ('largely through my own incompetence'), Professor Dixon left the Army in 1950 and entered university where he obtained a first-class degree in Psychology. He received the degrees of Doctor of Philosophy in 1956 and Doctor of Science in 1972, and in 1974 was awarded the University of London Carpenter Medal 'for work of exceptional distinction in Experimental Psychology'. He held an honorary doctorate from the University of Lund. His other books include: Preconscious Processing, Subliminal Perception: the nature of a controversy, which was described by Professor George Westby as 'one of the most substantial works of British psychology of recent years', and Our Own Worst Enemy, which New Society praised as 'an elegant play on man's chaotic nature...diverse and arresting'.
