An unconditioned stimulus is one that naturally and automatically triggers a certain behavioral response. A certain stimulus or environment can become a conditioned cue or a conditioned context, respectively, when paired with an unconditioned stimulus. An example of this process is a fear conditioning paradigm using a mouse. In this instance, a ...
Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
It may also be called "conditioned suppression" or "conditioned fear response (CFR)." [1] It is an "emotional response" that results from classical conditioning, usually from the association of a relatively neutral stimulus with a painful or fear-inducing unconditional stimulus. As a result, the formerly neutral stimulus elicits fear.
Negative punishment (penalty) (also called "punishment by contingent withdrawal") occurs when a behavior (response) is followed by the removal of a stimulus, and the behavior is less likely to occur in the future. Example: When an employee puts their lunch in a communal refrigerator, it gets stolen before break time. The next time the employee ...
The conditioned emotional response is usually measured through its effect in suppressing an ongoing response. For example, a rat first learns to press a lever through operant conditioning. Classical conditioning follows: in a series of trials the rat is exposed to a CS, often a light or a noise. Each CS is followed by the US, an electric shock.
Punishment is any change in a human or animal's surroundings which, occurring after a given behavior or response, reduces the likelihood of that behavior occurring again in the future. Reinforcement, referring to any behavior that increases the likelihood that a response will occurs, plays a large role in punishment. Motivating operations (MO ...
A study in 1976 found that discrimination learning will occur when the stimuli is realistic but unfamiliar in the study using pigeons and fish. [ 7 ] Watanabe study in 1995 found that pigeons are able to detect physical similarities during a study that was reinforcing monet paintings and not picasso paintings.
The presentation of a neutral stimulus does not result in any particular response, but the presentation of an unconditioned stimulus results in an unconditioned response, which was the dogs salivating in Pavlov's experiments. After conditioning, the bell ringing became a conditioned stimulus. [2]
