Conditioning is a psychological term for what Ivan Pavlov described as the learning of "conditional" behavior. Most psychologists believe that there are two types of conditioning: classical conditioning and operant conditioning. Psychology (ancient Greek: psyche = soul or mind, logos/-ology = study of) is an academic and applied field involving the study of mind and behavior. ...

Behavior (or behaviour in Commonwealth English) refers to the actions or reactions of an object or organism, usually in relation to the environment. ... Classical conditioning, also called Pavlovian conditioning or respondent conditioning, is a type of learning found in animals, caused by the association (or pairing) of two stimuli or what Ivan Pavlov described as the learning of conditional behavior, therfore called conditioning. ... Operant conditioning, so named by psychologist B. F. Skinner, is the modification of behavior brought about over time by the consequences of said behavior. ...


As psychologists use the term, conditioning is less prescriptive than descriptive. While Pavlov explicitly conditioned his dogs to salivate to tones, the interest in Pavlov's work is that his explicit conditioning procedures are considered useful laboratory models for what happens in the natural world. People also display natural food-related behavior in response to stimuli that are reliably paired or associated with food. Pavlov merely provided a procedure for modeling and investigating these natural phenomena in the laboratory. Pavlov's model is still used to investigate the natural behavior of organisms.


Similarly, reinforcement and punishment are understood to be natural phenomena occurring moment by moment in the lives of all animals. Laboratory studies are designed to enlighten the investigator into the nature of these phenomena rather than to discover better techniques of social, political, or economic control.

Pavlov's dogs

The most famous example of conditioning involves the development of conditional salivary responses in Pavlov's dogs. If a tone was reliably sounded before the dogs were fed, the dogs would eventually start salivating when they heard the tone, even if no food was present. The dog's responses (salivation) to the tone are said to be conditional upon the dogs' experience with the pairings of the tone and food. Dogs that have not experienced this condition do not salivate when they hear tones. Pavlov's dogs are therefore said to have been conditioned. Their reactions to the tone have been changed through experience. Contents of Saliva In animals, saliva is produced in and secreted from the salivary glands. ... Trinomial name Canis lupus familiaris (Linnaeus, 1758) The dog is a canine mammal of the Order Carnivora and it has been argued it has been domesticated for between 12,000 years and perhaps for as long as 150,000 years based on recent genetic evidence. ...


Classical conditioning

See also: Classical conditioning Classical conditioning, also called Pavlovian conditioning or respondent conditioning, is a type of learning found in animals, caused by the association (or pairing) of two stimuli or what Ivan Pavlov described as the learning of conditional behavior, therfore called conditioning. ...


Classical conditioning--also called "Pavlovian conditioning" or "respondent conditioning"--involves learning about the association of two or more (usually external) stimuli. Classical conditioning is generally associated with Ivan Pavlov. When two things generally occur together, encountering one can bring the other to mind (cf., Aristotle's law of contiguity). Thus, when Pavlov's dog hears the tone, salivation and other food-related responses occur because the tone and food commonly occurred together. These terms were chosen to reflect that no experience or conditions were needed for this stimulus-response relationship to occur. The food and salivation were part of an unconditional reflex. Ivan Pavlov Ivan Petrovich Pavlov (Иван Петрович Павлов) (September 14, 1849 – February 27, 1936) was a Russian physiologist and physician. ... Classical conditioning, also called Pavlovian conditioning or respondent conditioning, is a type of learning found in animals, caused by the association (or pairing) of two stimuli. ... A stimulus is the following: In physiology, a stimulus (physiology) is something external that elicits or influences a physiological or psychological activity or response. ... Ivan Pavlov Ivan Petrovich Pavlov (Иван Петрович Павлов) (September 14, 1849 – February 27, 1936) was a Russian physiologist and physician. ... Aristotle, marble copy of bronze by Lysippos. ...

The tone, however, initially elicited no food-related responses, and was therefore termed a neutral stimulus (abbreviated NS). After the dog experienced the pairings of the tone and food, however, the effects of the tone were changed. The previously neutral tone began to elicit salivation. The newly conditioned tone, therefore, was called a conditional stimulus (abbreviated CS) because its effects on food-related responses were conditional upon the dog's experiences. The salivation elicited by the tone, also conditional upon the dog's experience, was called a conditioned (or conditional) response (abbreviated CR). After conditioning, the tone and salivation were part of a conditional reflex.
Extinction of a conditional reflex occurs when the conditional stimulus is repeatedly presented in the absence of the unconditional stimulus. Food-related responses to conditional stimulus generally cease over the course of extinction.
Classical conditioning is involved in a number of important phenomena, like taste aversions, phobias, sexual fetishes, immune function, drug tolerance, and drug overdose.

Operant conditioning

See also: Operant conditioning

Operant conditioning, also called "instrumental conditioning", involves the modification of behavior due to the consequences of behavior. When a response or act is followed by a reinforcing consequence, the future probability of the response increases. When a response or act is followed by a punishing consequence, the future probability of the response decreases. Operant conditioning is generally associated with B.F. Skinner (1938, 1953, 1957). During reinforcement and punishment, the behavior of an organism is changed by the experience of the coincidence of the response and consequence (some would say the contingency between the response and consequence). The organism (or the response) is thus said to have been conditioned. Operant conditioning, so named by psychologist B. F. Skinner, is the modification of behavior brought about over time by the consequences of said behavior. ... In operant conditioning, reinforcement is any change in an animals surroundings that (a) occurs after the animal behaves in a given way, (b) seems to make that behavior re-occur more often in the future and (c) that reoccurrence of behavior must be the result of the change. ... Punishment is the practice of imposing something unpleasant on a wrongdoer as a response to something unwanted that the wrongdoer has done. ... Burrhus Frederic Skinner (March 20, 1904 _ August 18, 1990) was an American psychologist and author. ...

A typical example of operant conditioning in the laboratory would be a comparison of the response rates of rats under two conditions. In the first, rats are allowed to press a lever with no programmed consequence. In the second, rats are allowed to press a lever with the result that each lever press is immediately followed by giving the rat a small portion of food. Generally, the rate of lever pressing is higher in the second condition. It is then said that lever pressing was reinforced by the presentation of food, or that the response-contingent presentation of food strengthed lever pressing.
Consequences can be either reinforcing (strengthening the response) or punishing (weakening the response).

The application of the principles of operant conditioning to social situations such as parenting or therapy is called "behavior modification." The principle of the lever tells us that the above is in static equilibrium, with all forces balancing, if F1D1 = F2D2. ...

Classical Conditioning (1120 words)
In this chapter we will look at Classical Conditioning, perhaps the oldest model of change there is. It has several interesting applications to the classroom, ones you may not have thought about it.
Conditioning Stimulus: a new stimulus we deliver the same time we give the old stimulus.
Conditioned Relationship: the new stimulus-response relationship we created by associating a new stimulus with an old response.
Conditioning (2751 words)
A further principle of operant conditioning is that it is possible to condition an individual to perform behaviors outside of their usual repertoire.
This response is known as a conditioned response (CR) because it is occurring in response to the CS.
Classical conditioning can be contrasted with operant conditioning in that with respondent conditioning the CS leads to the CR, whereas in operant conditioning it is the Response that leads to the Stimulus.
