Pavlov on the conditioned reflex method and its limitations. Pavlov's contributions to behavior therapy. Here is a video showing a recreation of the experiment (not actual footage).Wolpe J, Plaud JJ. To make this experiment as reliable as possible Pavlov started using different conditional stimuli as well as different dogs and all presented the same exact results, showing that neural reflexes or social behavior can be trained to trigger by different stimulus than natural ones with repetition. As this experiment kept being carried day after day, the dog’s brain made the connection which led to the dog salivating only when hearing the ticking noise made by the metronome. Pavlov changed the experiment by hiding the food behind a screen before the dog would receive it and also adding a conditioned stimulus in the form of a sound made by a metronome. This was caused by the brain anticipating the same action would occur under familiar circumstances. After the same experiment was done a couple of times, the dog started to learn a pattern and salivate before seeing or eating the food. The salivation reflex, as Pavlov called it, was mainly triggered when the dog’s tongue made contact with food. Pavlov used his dog for this experiment where he surgically rerooted the saliva reduces to the outside of his dog's cheek in order to see when saliva was produced as well as to measure what sort of stimuli would produce more.Ī picture of Pavlov and his dog from 1893 (Source: RareHistoricalPhotos) Pavlov wanted to examine if this nervous reflex could be trained to be triggered by other stimuli apart from food. During his different experiments observing the biology of dogs, he discovered an interesting nervous reflex that dogs had where they would produce saliva only when they would either see food or eat it. Pavlov spent a lot of time studying the digestive system of dogs and why their gastric acid changes its acidity based on the dog’s diet. In the example above, the brain of the person taking a shower has developed a system where the brain predicts something is going to happen based on a conditioned stimulus (sound of a toilet being flushed) that was accompanied by an unconditioned stimulus (very hot water). The brain loves to create patterns that allow connections to be developed, thus fostering a more effective response time when encountering the same stimulus. Over time, the person starts to understand the pattern, and they automatically jump back when they hear a toilet flush even if the water coming out of the shower didn’t change temperature. Every time someone flushes a toilet in the apartment building the shower becomes very hot, making the person jump back. Imagine a person taking a shower with warm water. Here is an example that will help you better understand. Classical ConditioningĬlassical conditioning refers to the ability to control or trigger natural behaviors with a new stimulus. Pavlov’s experiment involving his dog helped to discover what today we call classical conditioning or respondent conditioning. This experiment took place in 1890 and was designed by Ivan Pavlov, a famous Russian Psychologist from the time who made tremendous advances in this particular field. However, one research stands out from them all. With theories that have been developed over the last two centuries, it became much easier to understand the psychology behind social behaviors. People think that psychology is something very complex, whilst it isn’t simple it is very easy to understand the social behavior of humans and how these are implied by the brain.
