George Armitage Miller (February 3, 1920 – July 22, 2012) was one of the founders of the cognitive psychology field. He also contributed to the birth of psycholinguistics and cognitive science in general. Miller wrote several books and directed the development of WordNet, an online word-linkage database usable by computer programs. He authored the paper, "The Magical Number Seven, Plus or Minus Two," which experimentally discovered an average limit of seven for human short-term memory capacity. This paper is frequently cited in both psychology and the wider culture. He also won awards such as the National Medal of Science.
Miller started his education focusing on speech and language and published papers on these topics, focusing on mathematical, computational and psychological aspects of the field. He started his career at a time when the reigning theory in psychology was behaviorism, which eschewed any attempt to study mental processes and focused only on observable behavior. Working mostly at Harvard University, MIT and Princeton University, Miller introduced experimental techniques to study the psychology of mental processes, by linking the new field of cognitive psychology to the broader area of cognitive science, including computation theory and linguistics. He collaborated and co-authored work with other figures in cognitive science and psycholinguistics, such as Noam Chomsky. For moving psychology into the realm of mental processes and for aligning that move with information theory, computation theory, and linguistics, Miller is considered one of the great twentieth-century psychologists.
