Pavlov experiment12/24/2022 ![]() ![]() To put this another way, it became clear that salivation was a learned response. Pavlov soon realized that he could teach his dogs to associate almost any sound, item, or event with the reward of food. He noticed that the dogs would begin salivating not when food was placed in front of them, but when they heard the footsteps of one of Pavlov’s assistants coming down the hall to bring food to them. While conducting his gastric experiment, Pavlov began to notice something peculiar. Pavlov couldn’t have predicted what happened next. This represents an unconditioned response in the animals, in which the sight and smell of the food causes them to salivate. Pavlov prediction that the dogs would salivate when presented with edible items was soon proved correct. As part of this research, Pavlov and his assistants would enter the room where the dogs were housed with a variety of edible and non-edible items, with the intention of measuring the amount of saliva that each dog produced when each item was placed in front of them. Pavlov had at the time been conducting research experiments into the dogs’ gastric systems. Pavlov’s dogs experiment came about as part of an accidental discovery. Ivan Pavlov’s dogs experiment is an experiment that took place in the 1890s in which the Russian physiologist surgically implanted small tubes into the cheeks of dogs to measure the buildup of saliva that took place under a variety of conditions. ![]() In this article I’m going to look into Pavlov’s dogs experiment, followed by a detailed look at the what, where, and why of Pavlovian conditioning, before moving on to a section on further reading for anyone interested in learning more about where this field has moved to since. ![]() Despite this, Pavlov’s most well-known contribution to science was through his dogs experiments, which became the basis for Pavlovian conditioning (also known as classical conditioning). Classical conditioning ignores the role of cognitive and biological factors which have also been shown to play a role in learning.Ivan Petrovich Pavlov (1849-1936) lived during a golden age of scientific discovery.īorn into the Russian Empire, and known within his family for being intellectually curious and unusually energetic from a young age, Pavlov won the Nobel Prize in Physiology or Medicine in 1904 for his work on the physiology of digestion, making him the first Russian Nobel laureate. ![]() There must be other learning processes involved. However, much human behaviour is voluntary and therefore cannot be explained by Classical Conditioning. Classical conditioning is limited to explaining how reflex responses become associated with new stimuli.Whilst conditioning may be useful in explaining animal behaviour, it may not be very useful in explaining learning in humans. Therefore, generalisations between humans and animals must be made with caution. Although there is supporting evidence, like little Albert, generalising and applying the findings of dogs to humans is still very difficult. This means that it is impossible for all these processes to be observed. Although conditioning can be observed in dogs and most species, human behaviour is driven by complex emotions and thought processes. The use of animals is a criticism of Pavlov's research.It also provides useful counter conditioning treatments, including systematic desensitisation (used to extinguish phobia's such as that of 'little Albert'). Valuable contribution to society - Pavlov's research provides powerful explanations for the development of a variety of behaviour s including psychological disorders.High Credibility - Other elements of Pavlov's research have been supported in Watson & Rayner's research: Albert's anxiety response had generalised from the white rat to some other white furry objects that were similar to the white rat (ie: cotton wool and a white stick on beard).Before: Noise (UCS) = Anxiety (UCR) - During: Noise (UCS) + Rat (NS) = Anxiety (UCR) - After: Rat (CS) = Anxiety (CR) Their study involved conditioning an 18 month old boy, Little Albert to develop a phobia of a white rat by pairing the rat with a loud noise. One famous study of Watson & Rayner (1920) supports Pavlov's research and links Classical Conditioning to be an element that effects the development of phobias. Insight into the development of phobias - Pavlov's research of learning via stimulus-response has been successfully applies to humans.Pavlov's research is viewed as an excellent example of scientific research - giving psychology greater credibility and respect. He is able to infer cause and effect due to his insistence on objectivity, control over variable and precise measurements learning can be conditioned via stimulus and response. Empirical Research - Pavlov used experiments to test his theory of Classical Conditioning. ![]()
