Murray Sidman (original) (raw)

Murray Sidman (April 29, 1923 – May 18, 2019) was a behavioral scientist, best known for Sidman Avoidance, also called "free-operant avoidance", in which an individual learns to avoid an aversive stimulus by remembering to produce the response without any other stimulus. Sidman's explanation of free-operant avoidance is an alternative to the Miller-Mowrer two-process theory of avoidance.
