Ivan Pavlov 's Classical Conditioning

Classical conditioning is a type of associative learning which occurs when two stimuli are paired together repetitively and therefore become associated with each other eventually producing the same response. Classical conditioning was developed from the findings of Ivan Pavlov to account for associations between neutral stimuli and reflexive behavior such as salivation. Pavlov (1927) accidently discovered that dogs began to salivate before they had tasted their food. To support his theory, he carried out experiments using dogs which involved measuring the amount of saliva they produced. In his experiments, food started off as an unconditioned stimulus (UCS) which produced salivation, an unconditioned response (UCR). They are both unconditioned as they occur naturally without being learned. The dogs were presented with a bell (NS), this provided no salivation. The bell and food were presented together and after many trails an

Classical conditioning is a type of learning in which an organism learns to transfer a natural response from one stimulus to another, previously neutral stimulus. Classical conditioning is achieved by manipulating reflexes. Operant conditioning is a type of learning in which the likelihood of a

Classical conditioning is a form of learning that is taught to us through experiences we encounter in our lives. It involves outside stimuli to trigger the condition we have learned to expect. For example, the sound of a lunch bell would trigger our stomach to start growling soon after hearing the bell ring. The expectation of food to come soon after hearing the bell and satisfy our hunger is what makes our stomach growl. This is something learned over time. Expectations can be both good and bad. Sometimes these negative experiences cause us to have certain behaviors when we are reminded of such an event.

There are seven basic processes to classical conditioning. The first process is acquisition which occurs when the conditioned stimulus elicits a response for the first time (Davey, 1992). The second process is stimulus contiguity which says that the two events (unconditioned stimulus and the conditioned stimulus) will more likely become associated with each other if they occur within a small time interval (Davey, 1992). The third process is extinction which is when the conditioned response weakens and disappears due to lack of reinforcement (Davey, 1992). The fourth process is spontaneous recovery which is when the conditioned response re-emerges after extinction has occurred (Comer, et al, 2013). The fifth process is stimulus generalisation which occurs when the response is elicited by more than one similar stimuli (Davey, 1992). The sixth process is stimulus discrimination which is when the same response is not elicited by two conditioned stimuli (Davey, 1992). The seventh and final process is higher-order conditioning which can be intentional or unintentional and occurs when a conditioned response occurs to more than one stimulus (Davey,

“Classical conditioning is a type of learning in which a stimulus acquires the capacity to evoke a response that was originally evoked by another stimulus”.

Learning is a fascinating concept. Everyone does it and everyone always has, but not everyone explores its eclectic process. That being said, through the course of history, it has been studied vehemently. Ivan Pavlov, a behaviorist, had some groundbreaking research on subclass of learning called classical conditioning. Coming across it incidentally, he discovered that dogs would salivate not only from eating food, but anything associated with them getting fed. Anything unnatural in their feeding process, he termed as the conditioned stimulus, which would result in the conditioned response of them salivating (Daniels). Though classical conditioning seems rather simple and commonsensible, the information psychologists have gathered from it has been revolutionary. It has shown psychologists the very basics of how we learn and adapt as organisms and opened the door for other studies (Myers 268). According to psychologists, learning is the process of acquiring new and relatively enduring information or behaviors (Myers 268).

Another behavioural psychologist, Watson (1915) was influenced by Pavlov’s dogs’ (1902). Watson suggested that if reflexes can be conditioned in dogs, then they can be conditioned in human behaviour too (Gross 2010). Watson used Pavlov’s idea of classical conditioning to influence his experiment with Little Albert, where Watson successfully conditioned fear into an 8-month-old boy using a range of different stimuli.

This lab is focused on the ideas of classical and operant conditioning. Classical conditioning is when a neutral stimulus is paired with an unconditioned stimulus to elicit an unconditioned response. In time this turns the neutral stimulus into a conditioned stimulus that causes a conditioned response. Operant conditioning is a method of learning that occurs through reinforcements and punishments for behavior and encourages associating desirable or undesirable outcomes with certain behaviors.

Behaviourists use two types of processes to explain how people learn: classical conditioning (Ivan Pavlov) and operant conditioning (Frederic Skinner).In classic conditioning, individuals learn to associate stimuli when they occur together to a response. Therefore individuals learn to produce an existing response to a stimulus that is presented. Take for instance little Albert. The little boy that was classically conditioned to respond with anxiety to the stimulus of a white ray by Watson and Rayner.

Classic Conditioning can also be known as stimulus response, conditioned response, respondent condition as these are the behaviors that take place during the Classical Conditioning. There are two basic forms of associative conditioning, classical and operant. Both Ivan Pavlov and John Watson were the first contributors to these behaviorist theories. Ivan Pavlov’s theory came about by working a dog and John Watson worked his classical conditioning with humans.

Many people who suffer from phobias also suffer from addictions. This is largely due in part to the reluctance to seek professional treatment for the phobia. People turn to other means to cope with their phobias which in turn leads to addictions. Dependence is such an issue with addiction that stopping is very difficult and causes severe physical and mental reactions. Therapist use a technique called extinction to treat patients with phobias and addictions.

This is known as the unconditioned stimulus (UCS). Meat is the unconditioned stimulus because at the sight of the meat the dogs begin to salivate (Feldman, 2010).   The dog’s response to the meat educes salivation and is known as the unconditioned response (UCR). An unconditioned response is defined as a reflexive and natural response that is not connected to prior learning. Unconditioned responses always occur in the presence of the unconditioned stimulus (Feldman, 2010).   While conditioning the dogs, Pavlov would ring a bell right before the presentation of meat. Eventually, the dogs would associate the ringing of the bell with the meat. Therefore, the dogs would begin to salivate at the sound of the bell. At this point, Pavlov could state that he had classically conditioned his dogs. The bell which was a prior neutral stimulus had now become the conditioned stimulus (CS) that brought forth the conditioned response (CR) of salivation (Feldman, 2010). Moreover, we have to ask what would happen if these poor dogs were never again received food upon the ringing of the bell. This would lead to extinction. Extinction occurs when a prior conditioned response decreases in frequency and eventually disappears (Feldman, 2010).   In order for Pavlov to unconditioned his dogs he would have to break their association with the sound of the ringing bell and the presentation of food. To do so he

* Ivan Pavlov (behaviorist) – Started the idea of conditioning, where an inherited reflex comes to be triggered by a stimulus that has nothing to do with that reflex. He showed that even inherited reflexes could be influenced dramatically by learning experiences.

Conditioning; the act or process of training a person or animal to do something or to behave in a certain way in a particular situation. To be more thorough; a simple form of learning involving the formation, strengthening, or weakening of an association between a stimulus and a response, as define by Merriam-Webster Online. Dictionary (2015)

Skinner believed that classical conditioning was limited to behaviors that are reflexively elicited. An operant describes behaviors that are "operate upon the environment to generate consequences." Reinforcement follows an operant and increases the likelihood of the operant being repeated.
