ABSTRACT
An enduring problem for psychology is whether it should be kept from reductionist dissolution in a sea of neurological details. Those psychologists who view such reduction as a scientific necessity focus on the learning of single responses. They indefinitely postpone study of the “chaining” of such isolated responses into “higher order” structures. Single stimulus-response connections are interpretable in terms of isolated behavioral units for which there is hope of finding sensory-motor analogues.
