ABSTRACT
This chapter limits to a consideration of Jerzy Konorski's main thoughts on the role of inhibition in conditioning, developed during the first and the second periods of his scientific activity. One of the most important is related to the fact that Konorski's early papers are relatively unknown to Western psychologists, and even his 1948 volume passed almost unnoticed in the USA. With excitatory classically conditioned reflexes, the change in behaviour occurring to the conditioned stimulus (CS) is a result of previous CS and unconditioned stimulus (US) pairings. Cedures are analyzed and consists of the parallel shaping of two different conditioned reflexes, each of them being a result of the particular contingencies used in training. Using a different line of analysis from that presented in the chapter, Konorski examines all of his experimental data again and came to the conclusion that both the terms 'internal inhibition' and inhibitory conditioned response (CR) are not adequate and should be abandoned.
