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.
Our task [in Project Pigeon] forced us to emphasize prior experimental control, and its success in revealing orderly processes gave us an exciting glimpse of the superiority of laboratory practice…
Psychologists have too often yielded to the temptation to be content with hypothetical processes and intervening variables rather than press for rigorous experimental control. It is often intellectual laziness rather…
Something happened during the brief life of Project Pigeon which it has taken a long time to appreciate. The practical task before us created a new attitude toward the behavior…
Tests made with the birds salvaged from the old Project Pigeon showed that even after six years of inactivity a pigeon will immediately and correctly strike a target to which…
The ethical question of our right to convert a lower creature into an unwitting hero is a peacetime luxury. There were bigger questions to be answered in the late thirties.…
Man has always made use of the sensory capacities of animals, either because they are more acute than his own or more convenient. The watchdog probably hears better than his…
... on the side of the observer, it would be a mistake to identify the understanding of design with its enjoyment. The processes involved in reacting to design seem to…
Even though we may eventually achieve an exhaustive list of the processes involved in the practice of design, the production of a work of art will probably still require that…
The artist is not so much interested in the physical structure of a design as in the effect it has upon the one who looks at it. This happens also…
The title “Baby in a Box” was not mine; it was invented by the editors of the Journal. Nevertheless, the Air-Crib is a sort of box, and this is also…
The experiment should, of course, be repeated again and again with different babies and different parents. One case is enough, however, to disprove the flat assertion that it can’t be…
A few critics have objected that they would not like to live in such a compartment themselves—they feel that it would stifle them or give them claustrophobia. The baby obviously…
Before the baby was born, when we were still building the apparatus, some of the friends and acquaintances who had heard about what we proposed to do were rather shocked.…
Every effort should be made to discover just why a baby cries. But if the condition cannot be remedied, there is no reason why the family, and perhaps the neighborhood…
The discovery which pleased us most was that crying and fussing could always be stopped by slightly lowering the temperature. During the first three months, it is true, the baby…
Raising or lowering the temperature by more than a degree or two produces a surprising change in the baby’s condition and behavior. This response is so sensitive that we wonder…
After a little experimentation we found that our baby, when first home from the hospital, was completely comfortable and relaxed without benefit of clothing at about 86° F. As she…
When we decided to have another child, my wife and I felt that it was time to apply a little labor-saving invention and design to the problems of the nursery…
The remedy [when a child’s voice has become annoyingly high] is simply for the mother to make sure that she responds with attention and affection to most if not all…
The mother may unwittingly promote the very behavior she does not want. For example, when she is busy she is likely not to respond to a call or request made…
A familiar problem is that of the child who seems to take an almost pathological delight in annoying its parents. In many cases this is the result of conditioning which…
A scientific analysis can ... bring about a better understanding of personal relations. We are almost always reinforcing the behavior of others, whether we mean to be or not. (p.…
Unfortunately the science of behavior is not yet as successful in controlling emotion as it is in shaping practical behavior. (p. 611)
All this [differential reinforcement] may be easily used—and just as easily misused—in our relations with other people. (p. 611)
Important among human reinforcements are those aspects of the behavior of others, often very subtle, which we call “attention,” “approval” and “affection.” Behavior which is successful in achieving these reinforcements…
... the human infant can be reinforced by very trivial environmental events; it does not need such a reward as food. Almost any “feedback” from the environment is reinforcing if…
When relevant conditions have been controlled, the behavior of the organism is fully determined. (p. 610)
The increased precision of the laboratory also makes it possible to guarantee performance up to the point of almost complete certainty. (p. 610)
... you can make it appear that a pigeon can be taught to read. You simply use two printed cards bearing the words PECK and DON’T PECK, respectively. By reinforcing…
To be effective a reinforcement must be given almost simultaneously with the desired behavior; a delay of even one second destroys much of the effect. (p. 606)
[Reinforcement] makes it possible to shape an animal’s behavior almost as a sculptor shapes a lump of clay. (p. 606)
The second thing you will need [to test a teaching technique] is something your subject wants, say food. This serves as a reward or—to use a term which is less…
“Catch your rabbit” is the first item in a well-known recipe for rabbit stew. Your first move, of course, [to test a teaching technique] is to choose an experimental subject.…
It takes rather subtle laboratory conditions to test an animal’s full learning capacity, but the reader may be surprised at how much he can accomplish even under informal circumstances at…
We have already discovered enough about the nature of learning to devise training techniques which are much more rapid and give more reliable results than the rule-of-thumb methods of the…
Teaching, it is often said, is an art, but we have increasing reason to hope that it may eventually become a science. (p. 605)
... Watson was to be remembered for a long time, by both laymen and psychologists alike, for a too narrow interpretation of self-observation, for an extreme environmentalism, and for a…
[Watson] thought he saw the seeds of many behavior problems in early home experiences, and in his Psychological Care of the Infant and Child—a book he later publicly regretted—he cautioned…
The same taste for polemics led him into an extreme environmentalistic position . . . Like all those who want to do something about behavior, he had emphasized the possibility…
In the controversy which followed [his book, Psychology from the Standpoint of a Behaviorist], Watson’s taste for, and skill in, polemics led him into extreme positions from which he never…
In his most important book, Psychology from the Standpoint of a Behaviorist, published in 1919, Watson defined the field he wanted to see studied and assembled available techniques and facts.…
In dispensing with mentalistic explanations of behavior, Watson cleared the way for a scientific analysis. (p. 601)
In establishing the continuity of species Darwin had attributed mental processes to lower organisms . . . The inevitable reaction was epitomized in the writings of Lloyd Morgan, who argued…
[John Broadus Watson’s] place in the history of science, and something of his stature, are indicated by three names—Darwin, Lloyd Morgan, and Watson—which represent three critical changes in our conception…
If, on the other hand, reinforcements happen to occur relatively infrequently in the presence of A, a discrimination will develop in the opposite direction, as the result of which the…
. . . a stimulus present when a response is reinforced may acquire discriminative control over the response even though its presence at reinforcement is adventitious . . . This…
When we arrange a clock to present food every 15 sec., we are in effect basing our reinforcement upon a limited set of responses which frequently occur 15 sec. after…
The experiment might be said to demonstrate a sort of superstition. The bird behaves as if there were a causal relation between its behavior and the presentation of food, although…
Whenever we present a state of affairs which is known to be reinforcing at a given level of deprivation, we must suppose that conditioning takes place even though we have…
To say that a reinforcement is contingent upon a response may mean nothing more than that it follows the response . . . conditioning takes place presumably because of the…
