The theory can be thought of in minimal terms as "the process and outcome whereby the thinking and feeling person uses conscious awareness and choice to create human and environmental integration." (Roy, internet) This is different from her previous definition of adaptation, which stated that adaptation is "a positive response that promotes survival, growth, reproduction, and mastery." (Roy, internet).
John Broadus Watson was an American behavioral psychologist; He was a professor and director of the psychological laboratory at Johns Hopkins. "Watson emphasized the study of observable behavior, rejecting introspection and theories of the unconscious mind." Buckley 1989. He created the school of psychology known as behaviorism, in which behavior is described in terms of physiological responses to stimuli. Watson's work influenced B. F. Skinner in his groundbreaking studies of operant conditioning and his thoughts and tenets have been adapted to nursing models. Buckley 1989.
John B. Watson was a behaviorist and therefore he emphasized the study of observable behavior. His nursing model, rejected introspection &theories of the unconscious mind. The scientific and philosophical aspects of his nursing model were similar because of this. He described behavior in terms of terms of physiological responses to stimuli. Barone et al 1996 (p 64)
His theory and nursing model was primarily concerned with the increasing or decreasing of the likelihood of given response by manipulating the consequences of the response.
Although Watson's model is not very large on the philosophical tenets he did have a legitimate nursing model that is still implemented and taught in many schools of nursing to this day.
Although both Roy's and Watson's models are widely accepted and taught there are some who argue that these models are not feasible. In regard to Roy's model there are arguments that contend this model is in a sense to liberal to work. By that it is meant that the model is too personalized
