Burrhus Frederic Skinner was an American psychologist, behaviorist, author, inventor, and social philosopher. He was a professor of psychology at Harvard University from 1958 until his retirement in 1974.
Operant conditioning, also called instrumental conditioning, is a learning process where behaviors are modified through the association of stimuli with reinforcement or punishment. In it, operants—behaviors that affect one's environment—are conditioned to occur or not occur depending on the environmental consequences of the behavior.
Radical behaviorism is a "philosophy of the science of behavior" developed by B. F. Skinner. 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. The research in behavior analysis is called the experimental analysis of behavior and the application of the field is called applied behavior analysis (ABA), which was originally termed "behavior modification."
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. A central method was the examination of functional relations between environment and behavior, as opposed to hypothetico-deductive learning theory that had grown up in the comparative psychology of the 1920–1950 period. Skinner's approach was characterized by observation of measurable behavior which could be predicted and controlled. It owed its early success to the effectiveness of Skinner's procedures of operant conditioning, both in the laboratory and in behavior therapy.
Vivisection is surgery conducted for experimental purposes on a living organism, typically animals with a central nervous system, to view living internal structure. The word is, more broadly, used as a pejorative catch-all term for experimentation on live animals by organizations opposed to animal experimentation, but the term is rarely used by practising scientists. Human vivisection, such as live organ harvesting, has been perpetrated as a form of torture.
Behaviorism is a systematic approach to understanding the behavior of humans and animals. It assumes that behavior is either a reflex evoked 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 controlling stimuli. Although behaviorists generally accept the important role of heredity in determining behavior, they focus primarily on environmental events.
An animal model is a living, non-human, often genetic-engineered animal used during the research and investigation of human disease, for the purpose of better understanding the disease process without the risk of harming a human. Although biological activity in an animal model does not ensure an effect in humans, many drugs, treatments and cures for human diseases are developed in part with the guidance of animal models. Animal models representing specific taxonomic groups in the research and study of developmental processes are also referred to as model organisms. There are three main types of animal models: Homologous, Isomorphic and Predictive. Homologous animals have the same causes, symptoms and treatment options as would humans who have the same disease. Isomorphic animals share the same symptoms and treatments, only. Predictive models are similar to a particular human disease in only a couple of aspects. However, these are useful in isolating and making predictions about mechanisms of a set of disease features.
Relational frame theory (RFT) is a psychological theory of human language, cognition, and behaviour. It was developed originally by Steven C. Hayes of University of Nevada, Reno and has been extended in research, notably by Dermot Barnes-Holmes and colleagues of Ghent University.
In operant conditioning, the matching law is a quantitative relationship that holds between the relative rates of response and the relative rates of reinforcement in concurrent schedules of reinforcement. For example, if two response alternatives A and B are offered to an organism, the ratio of response rates to A and B equals the ratio of reinforcements yielded by each response. This law applies fairly well when non-human subjects are exposed to concurrent variable interval schedules ; its applicability in other situations is less clear, depending on the assumptions made and the details of the experimental situation. The generality of applicability of the matching law is subject of current debate.
Neal Elgar Miller was an American experimental psychologist. Described as an energetic man with a variety of interests, including physics, biology and writing, Miller entered the field of psychology to pursue these. With a background training in the sciences, he was inspired by professors and leading psychologists at the time to work on various areas in behavioral psychology and physiological psychology, specifically, relating visceral responses to behavior.
Melioration theory in behavioral psychology is a theoretical algorithm that predicts the matching law. Melioration theory is used as an explanation for why an organism makes choices based on the rewards or reinforcers it receives. The principle of melioration states that animals will invest increasing amounts of time and/or effort into whichever alternative is better. To meliorate essentially means to "make better".
The scalar timing or scalar expectancy theory (SET) is a model of the processes that govern behavior controlled by time. The model posits an internal clock, and particular memory and decision processes. SET is one of the most important models of animal timing behavior.
John Anthony Nevin was an American psychologist who was a professor of psychology at the University of New Hampshire.
In behavioral psychology, stimulus control is a phenomenon in operant conditioning that occurs when an organism behaves in one way in the presence of a given stimulus and another way in its absence. A stimulus that modifies behavior in this manner is either a discriminative stimulus (Sd) or stimulus delta (S-delta). Stimulus-based control of behavior occurs when the presence or absence of an Sd or S-delta controls the performance of a particular behavior. For example, the presence of a stop sign (S-delta) at a traffic intersection alerts the driver to stop driving and increases the probability that "braking" behavior will occur. Such behavior is said to be emitted because it does not force the behavior to occur since stimulus control is a direct result of historical reinforcement contingencies, as opposed to reflexive behavior that is said to be elicited through respondent conditioning.
Murray Sidman was a behavioral scientist, best known for Sidman Avoidance, also called "free-operant avoidance", in which an individual learns to avoid an aversive stimulus by remembering to produce the response without any other stimulus. Sidman's explanation of free-operant avoidance is an alternative to the Miller-Mowrer two-process theory of avoidance.
George W. Ainslie is an American psychiatrist, psychologist and behavioral economist.
Herbert S. Terrace is a professor of Psychology and Psychiatry at Columbia University. His work covers a broad set of research interests that include behaviorism, animal cognition, ape language and the evolution of language. He is the author of Nim: A Chimpanzee Who Learned Sign Language (1979) and Why Chimpanzees Can't Learn Language and Only Humans Can (2019). Terrace has made important contributions to comparative psychology, many of which have important implications for human psychology. These include discrimination learning, ape language, the evolution of language, and animal cognition.
Cyma Kathryn Van Petten is an American cognitive neuroscientist known for electrophysiological studies of language, memory, and cognition. She is Professor of Psychology at the State University of New York at Binghamton where she directs the Event-Related Potential Lab. Van Petten was recipient of the Early Career Award from the Society for Psychophysiological Research in 1994.
William D. Timberlake was a psychologist and animal behavior scientist. His work included behavioral economics, contrast effects, spatial cognition, adjunctive behavior, time horizons, and circadian entrainment of feeding and drug use. He is best known for his theoretical work: Behavior Systems Theory and the Disequilibrium Theory of reinforcement.
Anthony Charles Catania is an American researcher in behavior analysis known for his theoretical, experimental, and applied work. He is an Emeritus professor of psychology at the University of Maryland, Baltimore County (UMBC), where he taught and conducted research for 25 years prior to his retirement in 2008. He received a B.A. (1957) and M.A. (1958) at Columbia University in Psychology. He received his Ph.D. in Psychology at Harvard University in 1961. He remained at Harvard to conduct research as a postdoctoral researcher in B. F. Skinner's laboratory. Prior to his career at UMBC, he held a faculty position for nearly a decade at New York University (NYU).
