The errorless learning procedure is highly effective in reducing the number of responses to the S− during training. In Terrace's (1963) experiment, subjects trained with the conventional discrimination procedure averaged over 3000 S− (errors) responses during 28 sessions of training; whereas subjects trained with the errorless procedure averaged only 25 S− (errors) responses in the same ...
Shaping sometimes fails. An oft-cited example is an attempt by Marian and Keller Breland (students of B.F. Skinner) to shape a pig and a raccoon to deposit a coin in a piggy bank, using food as the reinforcer. Instead of learning to deposit the coin, the pig began to root it into the ground, and the raccoon "washed" and rubbed the coins together.
Radical behaviorism is a "philosophy of the science of behavior" developed by B. F. Skinner. [1] It refers to the philosophy behind behavior analysis, and is to be distinguished from methodological behaviorism—which has an intense emphasis on observable behaviors—by its inclusion of thinking, feeling, and other private events in the analysis of human and animal psychology.

Skinner became an atheist after a Christian teacher tried to assuage his fear of the hell that his grandmother described. [14] His brother Edward, two and a half years younger, died at age 16 of a cerebral hemorrhage. [15] Skinner's closest friend as a young boy was Raphael Miller, whom he called Doc because his father was a doctor.
Operant conditioning originated with Edward Thorndike, whose law of effect theorised that behaviors arise as a result of consequences as satisfying or discomforting. In the 20th century, operant conditioning was studied by behavioral psychologists, who believed that much of mind and behaviour is explained through environmental conditioning.
Behaviorism was first developed by John B. Watson (1912), who coined the term "behaviorism", and then B. F. Skinner who developed what is known as "radical behaviorism". Watson and Skinner rejected the idea that psychological data could be obtained through introspection or by an attempt to describe consciousness; all psychological data, in ...
Behaviorism is a systematic approach to understand the behavior of humans and other animals. [1] [2] It assumes that behavior is either a reflex elicited by the pairing of certain antecedent stimuli in the environment, or a consequence of that individual's history, including especially reinforcement and punishment contingencies, together with the individual's current motivational state and ...
The development of the human mind is complex and a debated subject, and may take place in a continuous or discontinuous fashion. [4] Continuous development, like the height of a child, is measurable and quantitative, while discontinuous development is qualitative, like hair or skin color, where those traits fall only under a few specific phenotypes.
