Classical Conditioning | Simply Psychology
Classical conditioning also known as Pavlovian or respondent conditioning is a behavioral mechanism in which a biologically potent stimulus e. food is paired with a previously neutral stimulus e. a bell. It also refers to the learning process that results from this pairing, through which the neutral stimulus comes to elicit a response e.
salivation that is usually similar to the one elicited by the potent stimulus. Classical conditioning is distinct from operant conditioning also phobias instrumental conditioningthrough which pavlovian conditioning strength of a voluntary behavior is modified by reinforcement or punishment. However, classical conditioning can affect operant conditioning in various phobias notably, classically conditioned stimuli may serve to reinforce operant responses, phobias.
Classical conditioning was first studied in detail by Ivan Pavlovwho conducted experiments with phobias and published his findings in During the Russian phobias study of digestionPavlov observed that the dogs serving as his subjects drooled when they were being served meat, phobias.
Classical conditioning is a basic behavioral mechanism, and its neural substrates are now beginning to be understood. Though it is sometimes phobias to distinguish classical conditioning from other forms of associative learning e. instrumental learning pavlovian conditioning human associative memoryphobias, a number of observations differentiate them, especially the contingencies whereby learning occurs.
Together with operant conditioningclassical conditioning became the foundation of behaviorisma school phobias psychology which was dominant in the midth century and is still an important influence on the practice of psychological phobias and the study of animal behavior. Classical conditioning has been applied in other areas as well. For example, it may affect the body's response to psychoactive drugs, the regulation of hunger, research on the neural basis of learning and memory, and in certain social phenomena such as the false consensus effect.
Classical conditioning occurs when a conditioned stimulus CS is paired with an unconditioned stimulus US. Usually, the conditioned stimulus is a neutral stimulus e. After pairing is repeated the organism exhibits a conditioned response CR to the conditioned stimulus phobias the conditioned stimulus is presented alone. A conditioned response may occur after only one pairing. Thus, pavlovian conditioning the UR, pavlovian conditioning, the CR is acquired through experience, and it is also less permanent than the UR.
Usually the conditioned response is similar to the unconditioned response, but sometimes phobias is quite different. For this and other reasons, most learning theorists suggest that the conditioned stimulus comes to signal or predict the unconditioned stimulus, and go on to analyze the consequences of this signal.
Rescorla provided a clear summary of this change pavlovian conditioning thinking, and its implications, in his article "Pavlovian conditioning: It's not what you think it is", phobias. Classical conditioning differs pavlovian conditioning operant or instrumental conditioning : in classical conditioning, behaviors are modified through the association of stimuli as described above, pavlovian conditioning, whereas pavlovian conditioning operant conditioning phobias are modified by the effect they produce i, phobias.
The best-known and most thorough early work on classical conditioning was done by Ivan Pavlovalthough Edwin Twitmyer published some related findings a year earlier.
He redirected the animal's digestive fluids outside the body, where they could be measured. Pavlov noticed that his dogs began to salivate in the presence of the technician who normally fed them, rather than simply salivating in the presence of food. Pavlov called the dogs' anticipatory salivation phobias secretion". Putting these informal observations to an experimental test, phobias, Phobias presented a stimulus e, pavlovian conditioning.
the sound of a metronome and then gave the dog food; after phobias few repetitions, the dogs started to salivate in response to the stimulus, phobias.
Pavlov concluded that if a particular stimulus in the dog's surroundings was present when the dog was given food then that stimulus could become associated with food and cause salivation on its own. In Pavlov's experiments the unconditioned stimulus US was the food because its effects did not depend on previous experience, phobias.
The metronome's sound is originally a neutral stimulus NS because it does not phobias salivation in the dogs. After conditioning, the metronome's sound becomes the conditioned stimulus CS or conditional stimulus; because its effects depend on its association with food, pavlovian conditioning.
The conditioned response CR is phobias response to the conditioned stimulus, pavlovian conditioning, whereas the unconditioned response UR corresponds to the unconditioned stimulus. Pavlov reported many basic facts about conditioning; for example, he pavlovian conditioning that learning occurred most rapidly when the interval between the Phobias and the appearance of the US was relatively short, phobias.
As noted earlier, it is often thought that the conditioned response is a replica of the unconditioned response, but Pavlov noted that saliva produced by the CS differs in composition from that produced by the US, phobias. In fact, pavlovian conditioning, the CR may be any new response to the previously neutral CS that can be clearly linked to experience with the conditional relationship of CS and US.
Learning is fastest in forward conditioning, phobias. During forward conditioning, phobias, the onset of the CS precedes the onset of the US in order to signal that the US will follow. During simultaneous conditioning, the CS and US are presented and terminated at the same time, pavlovian conditioning. For example: If a person hears a bell and has air puffed into their eye at the same time, and repeated pairings like this led to phobias person blinking when they hear the bell despite the puff of air being absent, this demonstrates that simultaneous conditioning has occurred.
Second-order or higher-order conditioning follow a two-step procedure. First a neutral stimulus "CS1" comes to signal a US through forward conditioning.
Then a second neutral stimulus "CS2" is paired with the first CS1 and comes to yield its own conditioned response. If a light is then paired with the bell, phobias, then the light may come to elicit pavlovian conditioning as well. The bell is the CS1 and pavlovian conditioning food is the US. The light becomes the CS2 once it is paired with the CS1, phobias.
Backward conditioning occurs when a CS immediately follows a US. This presumably phobias because the CS serves as a signal that the US has ended, pavlovian conditioning, rather than as a signal that the US is about to appear. In temporal conditioning, a US is presented at regular intervals, for instance every 10 minutes. Conditioning is said to have occurred when the CR tends to occur shortly before each US.
This suggests that animals have a biological clock that can serve as a CS. This method has also been used to study timing ability in animals see Animal cognition, pavlovian conditioning. The example below shows the temporal conditioning, pavlovian conditioning, as US such as food to a hungry mouse is simply delivered on a regular time schedule such phobias every thirty seconds. After sufficient exposure the mouse will begin to salivate just before the food delivery.
This then pavlovian conditioning it temporal conditioning as it would appear that the mouse is conditioned to the passage of time. In this procedure, the CS is paired with the US, but the US also occurs at other times. If this occurs, phobias, it is predicted that the US is likely to happen in the absence of the CS.
In other words, the CS does not "predict" the US. In this pavlovian conditioning, conditioning fails and the CS does not come to elicit a CR. In the extinction procedure, the CS is presented repeatedly in the absence of a US, phobias.
This is done after a CS has been conditioned by one of the methods above. When this is done, the CR frequency eventually returns to pre-training levels.
However, pavlovian conditioning does not eliminate the effects of the prior phobias. This is demonstrated by spontaneous recovery — when there is a sudden appearance of the CR after pavlovian conditioning occurs — and other related phenomena see "Recovery from extinction" below, phobias.
These phenomena can be explained by postulating pavlovian conditioning of inhibition when a weak stimulus is presented. During acquisition, pavlovian conditioning, the CS and US are paired as described above.
The extent of conditioning may pavlovian conditioning tracked by test trials, phobias. In these test trials, the CS is presented alone and the CR is measured. A single CS-US pairing may suffice to yield a CR on a test, but usually a number of pairings are necessary and there is a gradual increase in the conditioned response to the CS. The pavlovian conditioning of conditioning depends on a number of factors, phobias, such as the phobias and strength of both the CS and the US, previous experience and the animal's motivational state.
If the CS is presented without the US, and this process is repeated often enough, the CS will eventually stop eliciting a CR. At this point the CR is said to be "extinguished. External inhibition may be observed if a strong or unfamiliar stimulus is presented just before, or at the same time as, the CS. This causes a reduction in the conditioned response to the CS. Several procedures lead to the recovery of a CR that had been first conditioned and then extinguished.
This illustrates that the extinction procedure does not eliminate the effect of conditioning. Stimulus generalization is said to occur phobias, after a particular CS has come to elicit a CR, a similar test stimulus pavlovian conditioning found to elicit the same CR.
Usually the more similar the test stimulus is to the CS the stronger the CR will be to the test stimulus. One observes stimulus discrimination when phobias stimulus "CS1" elicits one CR and another stimulus "CS2" elicits either another CR or no CR at all, phobias.
This can pavlovian conditioning brought about by, for example, pairing CS1 with an effective US and presenting CS2 with no US. Latent inhibition refers to the observation that it takes longer for a familiar stimulus to become a CS than it does for a novel stimulus to become a CS, pavlovian conditioning, when the stimulus is paired with an effective US.
This is one of the most common ways to measure the strength of learning in classical conditioning, phobias. A typical example of this procedure is as follows: a rat first learns to press a lever through operant conditioning. Then, phobias, in a series of trials, the rat is exposed to a CS, a light or a pavlovian conditioning, followed by the US, a mild electric shock, pavlovian conditioning.
An association between the CS and US phobias, and the rat slows or stops pavlovian conditioning lever pressing when the CS comes on. The rate of pressing during the CS phobias the strength phobias classical conditioning; that is, phobias slower the rat presses, the stronger the association of the CS and the US. Slow pressing indicates a "fear" conditioned response, and it is an example of a conditioned emotional response; see section below.
A separate test for each CS CS1 and CS2 is performed. The blocking phobias is observed in a lack of conditional response phobias CS2, suggesting that the first phase of training blocked the acquisition of phobias second CS. Experiments on theoretical issues in conditioning have mostly been done on vertebrates, especially rats and pigeons. However, phobias, phobias has also been studied in invertebrates, and very important data on the neural basis of conditioning has come from experiments on the sea slug, Aplysia.
According pavlovian conditioning Pavlov, conditioning does not involve the pavlovian conditioning of any new behavior, but rather the tendency to respond in old ways to new stimuli.
Thus, he theorized that the CS merely substitutes for the US in evoking the reflex response. This explanation is called the stimulus-substitution theory of conditioning. Pavlov himself observed that a dog's saliva produced as a CR differed in composition from that produced as a UR. Phobias example: the unconditional response to electric shock is an increase in heart rate, whereas a CS that has been pavlovian conditioning with the electric shock elicits a decrease in heart rate, phobias.
However, it has been proposed [ by whom?
