william schoenfeld - conditioning the whole organism

Editorial onditioning the W hole Organism WrmN wE wmu~ saXrDE~rrs, each of us heard very early some truths about an organism and its behavior which we later repeated as teachers, and as quickly forgot on both occasions. One can be- come so accustomed to a truth that it seems a platitude. Its down- grading is all the smoother when we fail to see in it any concrete implications for our work. The phasic forgetting and rediscovery of such truths may be a source of the historian's observation that the progress of science is saltant and not unidirectional. The study of behavior can provide its share of examples. One of these, in which we seem. to be in the forgetting phase, involves two truths about an organism: The first is that an organism is a whole, an integrated system, all of whose parts and processes are inter- related and co-functioning; and the second, that all the life systems and processes of an organism, even those we call cyclical, are con- tinuous and sequentially dependent. These facts have been sub- merged for a long time now, partly because of the scientist's argu- ment that large phenomena need to be analyzed into their constituent parts for study; and partly because of certain unique doctrinal de- velopments in conditioning theory since the turn of the century. Of course, analysis is essential, but it is not necessary in a scientific analysis that we forget what we are dissecting-that we forget the mountain for its stones, the meadow for its grass, or the organism for its neurones and juices and twitchings and pressings. As for the doctrinal atmosphere of the day, it is a-draft with ideas like duality in the conditioning paradigm, and semantically spiced with rein- forcers, contingencies, respondents, and operants. Yet, our two sub- merged truths must finally outweigh all these. With them in mind, and other considerations aside, we may mull the question: Can autonomic responses be conditioned in operant fashion? Consider- able research activity is growing up around that question, while at the same time it is fascinating laymen who see in it a possible justi- fication of favored behavioral dogmas. It seems closer to our truths, however, to see the question as an unprofitable digression for be- havior theory. All conditioning procedures include the intrusion of stimuli into an organism's behavior stream. The patterns of intrusion, and the number of stimuli, may be varied in the many ways we know. Whenever an intrusion is made, however, it must be conceded that there are multiple effects in behavior. We may decide to measure 125
