On January 4, 2016, the B. F. Skinner Foundation launched a new project – Skinner’s Quote of the Day. Quotes from B. F. Skinner’s works, selected by renowned scientists, appear daily Monday-Friday in order, starting with Chapter 1 of each book and running all the way through the last chapter. We started with the Science and Human Behavior (January-December 2916), followed by About Behaviorism (January-November 2017), Contingencies of Reinforcement (January-October 2018), Recent Issues (October 2018-May 2019), Reflections on Behaviorism and Society (May 2019-February 2020), and now moving on to Upon Further Reflection (from February 10 2020).
You can leave your comments here (registered users only), or join the discussion on our open Facebook forum. Please keep your comments brief and directly related to the quote.
Prevailing practices [in American elementary and high school education] are derived from unscientific “philosophies of education” and from the personal experiences of administrators and teachers, and the results are particularly…
The experimental analysis of behavior is more than measurement. It is more than testing hypotheses. It is an empirical attack upon the manipulable variables of which behavior is a function.…
Behavior modification is environment modification, but this is not widely recognized. Very little current “behavioral science” is really behavioral, because prescientific modes of explanation still flourish, but behavior modification is…
The genetic history is at the moment beyond control, but the environmental history, past and present, can be supplemented and changed, and that is what is done in a genuine…
The theory which accompanies an experimental analysis is particularly helpful in justifying practice because behavior modification often means a vast change in the way in which we deal with people…
Techniques of behavior modification often seem, after the fact, like the plainest of common sense, but we should remember that they remained undiscovered or unused for a long time and…
The amenable conditions of the laboratory are likely to bring the researcher under the control of deferred consequences and to maintain his behavior when it is only intermittently reinforced. (p.…
The effects of reinforcement are often deferred and need to be mediated, and this is particularly true when reinforcement is used in place of punishment because the latter has quicker…
A contribution ... — from basic to applied — would traditionally be described as the “confidence” with which contingencies are now designed in solving practical problems. Laboratory successes generalize to…
... an important difference [between basic and applied research] lies in the reasons why research is undertaken and supported. The applied researcher is under the influence of a special kind…
It is hard to see the contingencies of reinforcement which prevail in daily life and hence to understand the behavior they generate.4 Laboratory research tells us what to look for…
The behavior modification of the future will also make a far more extensive use of the control exerted by the current environment, of deprivation and satiation, of the conditioning of…
Another useful principle discovered in basic research has to do with the maintenance of behavior . . . Schedules are now widely used to solve what are essentially practical problems—for…
Evidently it is hard for a rat to acquire the operant of “letting go.” It lets go of an object when it is either punished or not reinforced for holding…
An early effort to shape complex behavior was suggested by an experiment in which a chimpanzee used poker chips to operate a sort of vending machine.1 It was implied by…
Most improvements in technology now come from what is essentially basic research. Behavior modification is an example. Its origins lay in a relatively “pure” experimental analysis. (p. 322)
The first scientific laws were probably the rules of craftsmen. In other words, science seems to have emerged from efforts to solve practical problems ... As science advances, however, the…
It is not inconceivable that the mental apparatus and all that it implies will be forgotten. It will then be more than a mere working hypothesis to say. . .…
Terms which refer to private events tend to be used inexactly. Most of them are borrowed in the first place from descriptions of external events. (Almost all the Vocabulary of…
It is easy to teach a child to distinguish between colors by presenting different colors and reinforcing his responses as right or wrong accordingly, but it is much more difficult…
That a small part of the universe is enclosed within the skin of each of us, and that this constitutes a private world to which each of us has a…
. . . we should probably remain blind if visual stimuli were never of any importance to us, just as we do not hear all the separate instruments in a…
Philosophers have often insisted that we are not aware of a difference until it makes a difference, and experimental evidence is beginning to accumulate in support of the view that…
A comprehensive set of causal relations stated with the greatest possible precision is the best contribution which we, as students of behavior, can make in the co-operative venture of giving…
The task of physiology is not to find hungers, fears, habits, instincts, personalities, psychic energy, or acts of willing, attending, repressing, and so on . . . Its task is…
The practical criteria of prediction and control will force us to take into account the complete causal chain in every instance. Such a program is not concerned with establishing the…
What is needed is an operational definition of terms. This means more than simple translation. The operational method is commonly misused to patch up and preserve concepts which are cherished…
No matter how we may wish to represent such a sequence of causal events, we cannot satisfy the requirements of interpretation, prediction, or control unless we go back to events…
Although speculation about what goes on within the organism seems to show a concern for completing a causal chain, in practice it tends to have the opposite effect. Chains are…
A man may walk down the street in precisely the same way upon two occasions, although in one instance he is out for exercise and in another he is going…
In any event, the newly conceived organism begins at once to be influenced by its environment; and when it comes into full contact with the external world, environmental forces assume…
Among the conditions which affect behavior, hereditary factors occupy a primary position, at least chronologically. (p. 308)
The study of behavior, psychotic or otherwise, remains securely in the company of the natural sciences so long as we take as our subject matter the observable activity of the…
The study of human behavior is, of course, still in its infancy, and it would be rash to suppose that anyone can foresee the structure of a well-developed and successful…
In the long run, of course, mere interpretation is not enough. If we have achieved a true scientific understanding of man, we should be able to prove this in the…
Of all the myriad aspects of behavior which present themselves to observation, which are worth watching? Which will prove most useful in establishing functional relations? . . . Frequency of…
Within a limited experimental arrangement, my colleagues and I have been able to demonstrate a lawfulness in behavior which seems to us quite remarkable. (p. 304)
The object [of my research] has been to discover the functional relations which prevail between measurable aspects of behavior and various conditions and events in the life of the organism.…
It is fairly easy to get another person onto an arbitrarily chosen topic during a conversation by showing attention when the topic is being approached and inattention when it is…
Several experiments are now in the literature in which an interviewer has skillfully shaped, by very slight reinforcements and punishments, the verbal behavior of the person being interviewed. (p. 302)
It will be recalled that the old introspective psychologist had a trained observer, but it is now clear that in training him the psychologist was definitely shaping the way in…
We acquire the vocabulary which describes our own behavior under great difficulty. The verbal community which can easily teach a child to distinguish colors, for example, cannot with the same…
It is reasonable to suppose that such an experimental science will eventually produce a technology capable of modifying and sustaining any given pattern of behavior almost at will. (p. 299)
Recent work in the field of learning has enabled the psychologist to achieve an extensive control over the behavior of an organism, and to bring this behavior under the control…
Modes of behavior characteristic of mental disease may be simply the result of a history of reinforcement, an unusual condition of deprivation or satiation, or an emotionally exciting circumstance. (p.…
Of special importance in the field of mental disease are many forms of behavior resulting from the use of punishment as a measure of control. It is now clear that…
Freud appears never to have considered the possibility of bringing the concepts and theories of a psychological science into contact with the rest of physical and biological science by the…
Freud’s contribution has been widely misunderstood. The important point was not that the individual was often unable to describe important aspects of his own behavior or identify important causal relationships…
There are many words in the layman’s vocabulary which suggest the activity of an organism yet are not descriptive of behavior in the narrower sense . . . We say…
In spite of Freud’s valuable analysis of verbal slips and of the techniques of wit and verbal art, he rejected the possibility of an analysis of verbal behavior in its…
