Murray Sidman (1923-2019) was an influential American behavioral scientist known for his work on 'Sidman Avoidance' or 'free-operant avoidance.' This concept describes a way an organism can learn to avoid an unpleasant stimulus through a specific response when there are no indicators suggesting an impending aversive stimulus. His explanation of this behavior presents an alternative to the Miller-Mowrer two-process theory of avoidance, which has been significant in the field of behavioral psychology.
