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.
The machine embodies key elements of Skinner's theory of learning and had important implications for education in general and classroom instruction in particular. [ 45 ] In one incarnation, the machine was a box that housed a list of questions that could be viewed one at a time through a small window.
The experimental analysis of behavior is a science that studies the behavior of individuals across a variety of species. A key early scientist was B. F. Skinner who discovered operant behavior, reinforcers, secondary reinforcers, contingencies of reinforcement, stimulus control, shaping, intermittent schedules, discrimination, and generalization.
Skinner box. An operant conditioning chamber (also known as a Skinner box) is a laboratory apparatus used to study animal behavior. The operant conditioning chamber was created by B. F. Skinner while he was a graduate student at Harvard University. The chamber can be used to study both operant conditioning and classical conditioning. [1] [2]
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. [2]
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 ...
B. F. Skinner was responsible for a different type of machine which used his ideas on how learning should be directed with positive reinforcement. [8] Skinner advocated the use of teaching machines for a broad range of students (e.g., preschool aged to adult) and instructional purposes (e.g., reading and music).
The basic learning principles constitute another level of theory, as do the human learning principles that specify cumulative learning. How the principles work—in areas like child development, personality, abnormal personality, clinical treatment, education, and human evolution—compose additional levels of study.
