P. J. Woods's (see record 1975-00351-001) article on a taxonomy of instrumental conditioning is merely a simplified duplication of J. Cohen's (1969) more sophisticated taxonomy of operant conditioning techniques. Woods's insistence on an operant conditioned response (CR) without a discriminative stimulus seems untenable.
