One of them is Joseph Wolpe in South Africa who worked with the model of classical conditioning or Pavlovian. Wolpe demonstrated how could unlearn it or inhibit the conditioned anxiety. On the basis of the work of Hull (1884-1952) and the results obtained with their own experimental neurosis, he established the important principle of the reciprocal inhibition. Another researcher who worked from the perspective of classical conditioning is H.J. Eysenck, who approached with much scientific rigour the study of personality.From the 1960s, develops imitative or observational learning that studies under what conditions are acquired, or disappear, behavior by the imitation process.
This was introduced by Bandura and Walters who describe a learning model that has a mediational base: the individual appears as an active intermediary between stimulus and response.This orientation mediational acquires great relevance in the decades of the 60 and 70 and in the development of cognitive currents since, from the sixties, several authors begin to work applying the behaviorist methodology to subjective psychological processes. The pioneering work on this line relate to Albert Ellis, who developed a form of psychotherapy called rational emotive therapy (TRE). Later was complemented and expanded by various authors as Aaron Beck who proposed a psychopathological model of cognitive base and a therapy cognitive behavioural therapy of depression; Martin Seligman that He worked on the depression phenomenon and proposed the model of learned despair; Donald Meichenbaum who developed a procedure known as autoinstruccional training; etc. All these models interact to determine the multiplicity of human behaviors, forming complex learning processes.
