Classical conditioning (also known as Pavlovian or respondent conditioning) is learning through association and was discovered by Pavlov, a Russian physiologist. In unproblematic terms, two stimuli are linked together to produce a new learned response in a person or animal.

John Watson proposed that the procedure of classical workout (based on Pavlov’due south observations) was able to explain all aspects of human psychology.

Everything from speech to emotional responses was simply patterns of stimulus and response. Watson denied completely the existence of the mind or consciousness. Watson believed that all individual differences in beliefs were due to different experiences of learning. He famously said:

“Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I’ll guarantee to take any i at random and railroad train him to get any blazon of specialist I might select – doctor, lawyer, creative person, merchant-chief and, yeah, even ragamuffin-human and thief, regardless of his talents, penchants, tendencies, abilities, vocations and the race of his ancestors” (Watson, 1924, p. 104).

How Classical Workout Works

Stage ane: Before Workout:

In this stage, the unconditioned stimulus (UCS) produces an unconditioned response (UCR) in an organism.

In basic terms, this ways that a stimulus in the environs has produced a beliefs / response which is unlearned (i.e., unconditioned) and therefore is a natural response which has not been taught. In this respect, no new behavior has been learned yet.

For instance, a breadbasket virus (UCS) would produce a response of nausea (UCR). In another example, a perfume (UCS) could create a response of happiness or desire (UCR).

This stage also involves another stimulus which has no event on a person and is called the neutral stimulus (NS). The NS could be a person, object, place, etc.

The neutral stimulus in classical conditioning does not produce a response until it is paired with the unconditioned stimulus.

Stage 2: During Conditioning:

During this stage, a stimulus which produces no response (i.east., neutral) is associated with the unconditioned stimulus at which point it now becomes known as the conditioned stimulus (CS).

For classical conditioning to be effective, the conditioned stimulus should occur before the unconditioned stimulus, rather than after it, or during the aforementioned time. Thus, the conditioned stimulus acts as a type of point or cue for the unconditioned stimulus.

In some cases, conditioning may take place if the NS occurs after the UCS (backward conditioning), just this unremarkably disappears quite quickly. The most important aspect of the conditioning stimulus is the it helps the organism predict the coming of the unconditional stimulus.

Oft during this stage, the UCS must be associated with the CS on a number of occasions, or trials, for learning to take place. However, i trail learning tin can happen on certain occasions when it is not necessary for an clan to exist strengthened over fourth dimension (such equally being sick after food poisoning or drinking too much alcohol).

Stage 3: Afterwards Conditioning:

Now the conditioned stimulus (CS) has been associated with the unconditioned stimulus (UCS) to create a new conditioned response (CR).

For case, a person (CS) who has been associated with nice perfume (UCS) is at present establish attractive (CR). Also, chocolate (CS) which was eaten before a person was sick with a virus (UCS) now produces a response of nausea (CR).

Classical Conditioning Examples

Pavlov’s Dogs

The near famous example of classical conditioning was Ivan Pavlov’due south experiment with dogs, who salivated in response to a bong tone. Pavlov showed that when a bong was sounded each time the domestic dog was fed, the canis familiaris learned to associate the audio with the presentation of the food.

He starting time presented the dogs with the sound of a bell; they did not salivate and so this was a neutral stimulus. So he presented them with nutrient, they salivated. The food was an unconditioned stimulus and salivation was an unconditioned (innate) response.

He then repeatedly presented the dogs with the sound of the bell commencement and and then the nutrient (pairing) after a few repetitions the dogs salivated when they heard the sound of the bell. The bong had get the conditioned stimulus and salivation had become the conditioned response.

Fright Response

Watson & Rayner (1920) were the get-go psychologists to apply the principles of classical workout to human being behavior by looking at how this learning procedure may explicate the development of phobias.

They did this in what is at present considered to be one of the most ethically dubious experiments e’er conducted – the instance of Little Albert. Albert B.’s mother was a wet nurse in a children’s infirmary. Albert was described as ‘healthy from birth’ and ‘on the whole stolid and unemotional’.

When he was almost 9 months old, his reactions to various stimuli (including a white rat, burning newspapers and a hammer striking a four-pes steel bar just behind his head) were tested.

Merely the final of these frightened him, and then this was designated the unconditioned stimulus (UCS) and fear the unconditioned response (UCR). The other stimuli were neutral because they did non produce fear.

When Albert was merely over eleven months old, the rat and the UCS were presented together: equally Albert reached out to stroke the fauna, Watson struck the bar behind his head.

This occurred seven times in total over the next seven weeks. By this time the rat, the conditioned stimulus (CS), on its own frightened Albert, and fear was now a conditioned response (CR).

The CR transferred spontaneously to the rabbit, the dog and other stimuli that had been previously neutral. V days afterwards conditioning, the CR produced by the rat persisted. After ten days it was ‘much less marked’, but it was still evident a month later

Carter and Tiffany, 1999 support the cue reactivity theory, they carried out a meta-analysis reviewing 41 cue-reactivity studies that compared responses of alcoholics, cigarette smokers, cocaine addicts and heroin addicts to drug-related versus neutral stimuli. They plant that dependent individuals reacted strongly to the cues presented and reported craving and physiological arousal.

Addiction

Cue reactivity is the theory that people associate situations (due east.g. meeting with friends)/ places (e.k. pub) with the rewarding furnishings of nicotine, and these cues can trigger a feeling of peckish.

These factors go smoking-related cues. Prolonged apply of nicotine creates association between these factors and smoking. This is based on classical workout.

Nicotine is the unconditioned stimulus (UCS) and the pleasance caused past the sudden increment in dopamine levels is the unconditioned response (UCR). Following this increment, the encephalon tries to lower the dopamine back to a normal level.

The stimuli that accept become associated with nicotine were neutral stimuli (NS) before “learning” took identify merely they became conditioned stimuli (CS), with repeated pairings. They can produce the conditioned response (CR).

Still, if the brain has non received nicotine the levels of dopamine drop, and the individual experiences withdrawal symptoms therefore is more than likely to experience the need to smoke in the presence of the cues that have become associated with the use of nicotine

Classroom Learning

The implications of classical workout in the classroom are less important than those of operant workout, merely there is a however need for teachers to effort to make sure that students acquaintance positive emotional experiences with learning.

If a student associates negative emotional experiences with school, and so this can obviously accept bad results, such as creating a school phobia.

For example, if a student is bullied at school they may learn to associate the school with fear. It could also explain why some students prove a detail dislike of sure subjects that go on throughout their academic career. This could happen if a student is humiliated or punished in class by a teacher.

Principles of Classical Conditioning

Critical Evaluation

Classical conditioning emphasizes the importance of learning from the environment, and supports nurture over nature. Even so, information technology is limiting to describe behavior solely in terms of either nature or nurture, and attempts to practice this underestimate the complexity of man behavior. It is more likely that behavior is due to an interaction between nature (biology) and nurture (environment).

The behaviourist approach has been used in the treatment of phobias, systematic desensitisation. The individual with the phobia is taught relaxation techniques and then makes a bureaucracy of fright from the least frightening to the most frightening features of the phobic object. He and so is presented with the stimuli in that order and learns to associate (classical workout) the stimuli with a relaxation response. This is counter conditioning.

The process of classical conditioning tin can probably account for aspects of certain other mental disorders. For example, in post-traumatic stress disorder (PTSD) sufferers tend to show classically conditioned responses to stimuli present at the time of the traumatising event (Charney et al., 1993). Just since non everyone exposed to the traumatic event develops PTSD, other factors must be involved, such as individual differences in people’s appraisal of events as stressors and the recovery environment, such as family unit and support groups.

At that place accept been many laboratory demonstrations of man participants acquiring behavior through the process of classical conditioning. Information technology is relatively easy to classically condition and extinguish conditioned responses, such as the eye-blink and galvanic skin responses.

Still, applying classical conditioning to our understanding of complex human being behavior such as memory, thinking, reasoning or problem-solving has proved more problematic.

In normal adults the conditioning process can apparently be overridden by instructions: but telling participants that the unconditioned stimulus will not occur causes an instant loss of the conditioned response, which would otherwise extinguish only slowly (Davey, 1983).

Most participants in an experiment are aware of the experimenter’s contingencies (the relationship between stimuli and responses) and in the absence of such awareness often fail to show evidence of workout (Brewer, 1974).

There are also important differences between very young children or those with astringent learning difficulties and older children and adults regarding their behavior in a multifariousness of operant conditioning and discrimination learning experiments.

These seem largely attributable to linguistic communication evolution (Dugdale & Lowe, 1990). This suggests that people accept rather more efficient, language-based forms of learning at their disposal than just the laborious formation of associations between a conditioned stimulus and unconditioned stimulus.

Even beliefs therapy, one of the apparently more successful applications of workout principles to human beliefs, has given way to cognitive– behavior therapy (Mackintosh, 1995).

A strength of classical workout theory is that information technology is scientific. This is because it’southward based on empirical prove carried out by controlled experiments. For example, Pavlov (1902) showed how classical conditioning could be used to make a dog salivate to the sound of a bell.

Supporters of a reductionist approach say that it is scientific. Breaking complicated behaviors down to small parts means that they can be scientifically tested. All the same, some would argue that the reductionist view lacks validity. Thus, while reductionism is useful, it tin atomic number 82 to incomplete explanations.

A final criticism of classical conditioning theory is that information technology is deterministic. This ways that information technology does not permit for whatever degree of free will in the private. Accordingly, a person has no control over the reactions they take learned from classical workout, such as a phobia.

The deterministic arroyo besides has of import implications for psychology as a science. Scientists are interested in discovering laws which can then be used to predict events. Even so, by creating full general laws of behavior, deterministic psychology underestimates the uniqueness of human beings and their freedom to cull their ain destiny.
