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.
The law of effect was published by Edward Thorndike in 1905 and states that when an S-R association is established in instrumental conditioning between the instrumental response and the contextual stimuli that are present, the response is reinforced and the S-R association holds the sole responsibility for the occurrence of that behavior.
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.
Pavlovian fear conditioning is a behavioral paradigm in which organisms learn to predict aversive events. [1] It is a form of learning in which an aversive stimulus (e.g. an electrical shock) is associated with a particular neutral context (e.g., a room) or neutral stimulus (e.g., a tone), resulting in the expression of fear responses to the originally neutral stimulus or context.
The result of this conditioned stimulus is to provoke the unconditioned response, fear. The once neutral stimulus is given again to see if the rat would show the responses of fear. However, because fear responses involve many behaviors, it is important to see which behaviors are exhibited when the conditioned stimulus is given. [2]
The unconditioned stimulus is the dog's food that would naturally cause salivation, which is an unconditioned response. Pavlov then trained the dog by ringing the bell every time before food. The conditioned stimulus is the ringing bell after training, which causes salivation as a conditioned response. [3] [page needed]
Human contingency learning focuses on the acquisition and development of explicit or implicit knowledge of the relationships or statistical correlations between stimuli and responses. [1] It is similar to operant conditioning , which is a learning process where a behaviour can be encouraged or discouraged through praise or punishment.
For example, as a result of training, INP cells discharge prior to CR execution and fire in a pattern of increased frequency of response that predicts the temporal form of the behavioral CR (McCormick & Thompson, 1984). This pattern of activity clearly indicates that the INP is capable a generating a conditioned response.
