Unconditioned Stimulus Vs Response

A dog does not have to learn to feel pleasure when fed.
Unconditioned stimulus vs response. Conditioned and unconditioned responses are behaviors that result from specific stimuli. The connection between the two is determined by the biology of the organism. However a stimulus prompts a conditioned response only when someone has come to associate that stimulus with another.
A stimulus that doesn t naturally elicit a response is a neutral response. For example the child does not have to learn to feel pain from the shot. A stimulus is any internal or external thing that induces our nervous system to respond to it.
A conditioned response cr is one that is caused by a conditioned stimulus cs whereas an unconditioned response ur is caused by an unconditioned stimulus us. The concept of unconditioned responses was first defined by ivan pavlov as part of his discovery of classical conditioning. For example when you smell one of your favorite foods you may immediately feel hungry.
Unconditioned stimulus refers to any stimulus that naturally and automatically triggers a specific response in humans or organisms. Red meat will lead to the ur e g. The food powder is the unconditioned stimulus and the increased salivation is the unconditioned response ur.
In the learning process known as classical conditioning the unconditioned stimulus ucs is one that unconditionally naturally and automatically triggers a response. Unconditioned responses are natural and innate and therefore don t have to be learned. A controlled response is a response taught to said person by pairing it with a formally neutral stimulus.
The key difference between conditioned stimulus and unconditioned stimulus is that conditioned stimulus produces a learned response to the previously neutral stimulus while unconditioned stimulus produces a response without any previous learning. An unconditioned response is behavior that occurs naturally due to a given stimulus. Conditioned stimulus vs unconditioned stimulus the main difference between a conditioned stimulus and an unconditioned one is the former is a product of learned behavior.
