The uncontrollable, innate reaction itself is known as the unconditioned response, which in this case is salivation. In Stage 1: Before Conditioning, Pavlov presents the dog with food, which is an unconditioned stimulus, or an item that will elicit an uncontrollable, innate reaction. Through his experimentation, Pavlov discovered a three-stage process to classical conditioning. Intrigued by this new observation, Pavlov decided to structure a whole new experiment around making the dogs salivate in response to other random sounds. Since Ivan Pavlov was originally a physiologist, not a psychologist, he was in the middle of studying how the digestion process works in dogs when he realized that the dogs he was working with would already start drooling at the footstep-sounds of the assistant who fed them-not just when food was actually placed in front of them. After several repetitions of first presenting the environmental stimulus and then the natural stimulus to an animal, that organism will now give a response even when only presented with the environmental stimulus. DefinitionĬlassical conditioning, a learning process discovered by Russian physiologist Ivan Pavlov, occurs when an environmental stimulus which is not biologically-wired to get a certain response is repeatedly paired with a natural stimulus that is biologically-wired to get a response. This is a simplified explanation of how the psychological process of classical conditioning happens. The brain now identifies the taste of funnel cake as a good predictor of future nausea and creates a mental shortcut so that eating funnel cake will now immediately lead to nausea for Riona. The brain thought that perhaps these two actions always happen in this exact sequence and assumed that whenever Riona eats funnel cake, this is a sure sign that she will get on a rollercoaster soon after and become nauseous. What does this have to do with Riona’s predicament, you ask? Well, after her disastrous day at the carnival, Riona’s brain believed it had found a meaningful association between eating funnel cake and the intense motion of the roller coaster.
The human brain has evolved to very quickly pick up on potential patterns in a person’s surroundings. But if that’s true, why does the smallest taste of funnel cake now consistently make Riona nauseous after that day at the carnival? Here’s Why Looking at the situation from a logical perspective, most people would agree that Riona’s nausea was most likely caused by the intense motion of the roller coaster, not food poisoning from the funnel cake. Immediately after getting off the ride, Riona experiences nausea and an upset stomach. After eating the funnel cake, Riona waits for half an hour to digest the food before going on a super-popular new roller coaster called The Thrasher that violently twists and turns and loops around. The first thing she decides to do is buy her favorite fair food: funnel cake, loaded with plenty of powdered sugar and cinnamon. Dog drools.Riona is spending the day at a local carnival with her friends. After 4 hour delay, cat woke up, ate food, went back to sleep.ĭay 5: Read article about deaf blue-eyed white cats.ĭay 6: Cat woke me up by sitting on head. Cat opened eye (blue), yawned, complained about cheap brand of cat food.ĭay 4: Rang bell. Cat (white) rolled over and snored.ĭay 3: Rang bell. Pavlov's second attempt, with new cat possibly went something like this:ĭay 2: Rang bell. Who knows, it might even have rung the bell and conditioned him to open the door as well, just like my cat has conditioned me. The experiment might have worked had the cat not been buggering off to next door where it had already conditions Pavlov's neighbour to give it a nice plate of chicken liver. Many scientific discoveries have been made accidentally while trying ot prove something entirely different. Sure enough, the Pavlov's Cat experiment proves that scientists can be conditioned to eat cat food and that cats eat only when it suits them. His experiments went something along the lines of:ĭay 3: Rang bell, but cat put paw on bell so it only made a 'thunk' sound.ĭay 4: Rang bell, cat said he'd eaten earlier.ĭay 5: Tried to ring bell, but cat had taken batteries out of bell. Pavlov was a Welsh behavioural scientist who conducted experiments into ringing bells and cats eating food. Pavlov's Cats is a far more interesting a subtle experiment into feline-human behaviour. When put into a box with a decaying vial of poison which might or might not release the poison, Shroedinger's Dog chews the vial thus ensuring it ended up in a dead state every time. Let's not concern ourselves with Shroedinger's Dog, a creature so incredibly stupid and perpetually confused it has difficulty being in one state at a time let alone being in two states simultaneously. But what of Shroedinger's Dog and Pavlov's Cats? Everyone has heard of Pavlov's Dogs and many have heard of Schroedingers Cat.
