Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
John Garcia (June 12, 1917 – October 12, 2012 [1]) was an American psychologist, most known for his research on conditioned taste aversion. Garcia studied at the University of California-Berkeley, where he received his A.B., M.A., and Ph.D. degrees in 1955 in his late forties. At his death, he was professor emeritus at University of ...
John B. Watson. John Broadus Watson (January 9, 1878 – September 25, 1958) was an American psychologist who popularized the scientific theory of behaviorism, establishing it as a psychological school. [2] Watson advanced this change in the psychological discipline through his 1913 address at Columbia University, titled Psychology as the ...

Burrhus Frederic Skinner (March 20, 1904 – August 18, 1990) was an American psychologist, behaviorist, inventor, and social philosopher. [2][3][4][5] He was the Edgar Pierce Professor of Psychology at Harvard University from 1958 until his retirement in ...
Little Albert experiment. The Little Albert experiment was an unethical study that mid-20th century psychologists interpret as evidence of classical conditioning in humans. The study is also claimed to be an example of stimulus generalization although reading the research report demonstrates that fear did not generalize by color or tactile ...
Robert A. Rescorla (May 9, 1940 - March 24, 2020) [1] [2] was an American psychologist who specialized in the involvement of cognitive processes in classical conditioning [3] focusing on animal learning and behavior. [4] One of Rescorla's significant contributions to psychology, with co-creator Allan Wagner, was the Rescorla-Wagner Model of ...
The Rescorla–Wagner model (" R-W ") is a model of classical conditioning, in which learning is conceptualized in terms of associations between conditioned (CS) and unconditioned (US) stimuli. A strong CS-US association means that the CS signals predict the US. One might say that before conditioning, the subject is surprised by the US, but ...
Spontaneous recovery. Spontaneous recovery is a phenomenon of learning and memory that was first named and described by Ivan Pavlov in his studies of classical (Pavlovian) conditioning. In that context, it refers to the re-emergence of a previously extinguished conditioned response after a delay. [1]
