Notes from "Pavlov's Wednesdays": Pavlov's law of effect

Pavlov's Wednesday seminars indicate that he adopted homeostatic balance as a law of effect in order to deal with Konorski's experiments on omission and avoidance training; he did not, as is often thought, completely assimilate instrumental conditioning into his classical framework. He saw the 'new' type of conditioning as the basis of voluntary behavior in higher animals and devoted considerable attention to it in 1930-1933.
