|
Term
|
Definition
| a procedure in which the CS is presented shortly after the US on each trial |
|
|
Term
|
Definition
| a test procedure that identifies a stimulus as a conditioned inhibitor if that stimulus reduces the responding elicited by a conditioned excitatory stimulus; also called a summation test |
|
|
Term
| conditional or conditioned response |
|
Definition
| the response that comes to be made to the CS as a result of classical conditioning |
|
|
Term
| conditional or conditioned stimulus |
|
Definition
| a stimulus that does not elicit a particular response initially, but comes to do so as a result of becoming associated with an US |
|
|
Term
|
Definition
| suppression of ongoing behavior produced by the presentation of a CS that has been conditioned to elicit fear through association with an aversive US |
|
|
Term
|
Definition
| a training episode involving presentation of a CS with (or without) a US |
|
|
Term
|
Definition
| same as interstimulus interval |
|
|
Term
|
Definition
| changing the hedonic value or liking of an initially neutral stimulus by having that stimulus associated with something that is already liked or disliked |
|
|
Term
| explicitly unpaired control |
|
Definition
| a procedure in which both CS and US are presented, but with sufficient time between them so that they do not become associated with each other |
|
|
Term
|
Definition
| conditioned behavior elicited by a CS that consists of approaching the location where the US is usually presented |
|
|
Term
|
Definition
| a type of classical conditioning in which the CS becomes a signal for the absence of the US |
|
|
Term
|
Definition
| the amount of time that elapses between the start of the CS and the start of the US during a classical conditioning trial |
|
|
Term
|
Definition
| the amount of time that elapses between two successive trials |
|
|
Term
|
Definition
| the time elapsed between a stimulus (or the start of a trial) and the response that is made to the stimulus |
|
|
Term
| lick-suppression procedure |
|
Definition
| a procedure for testing fear conditioning in which presentation of a fear-conditioned CS slows down the rate of drinking |
|
|
Term
| long-delayed conditioning |
|
Definition
| a conditioning procedure in which the US occurs more than several minutes after the start of the CS, as in taste-aversion learning |
|
|
Term
|
Definition
| a measure of the size, vigor, or extent of a response |
|
|
Term
|
Definition
| learning associations between different stimulus features of an object, such as what it looks like and how it tastes |
|
|
Term
| probability of a response |
|
Definition
| the likelihood of making the response, usually represented in terms of the percentage of trials on which the response occurs |
|
|
Term
|
Definition
| increased responding that may occur to a stimulus whose presentations are intermixed with presentations of a US in the absence of the establishment of an association between the stimulus and the US |
|
|
Term
|
Definition
| a procedure in which the CS and US are presented at random times with respect to each other |
|
|
Term
| retardation of acquisition test |
|
Definition
| a test procedure that identifies a stimulus as a conditioned inhibitor if that stimulus is slower to acquire excitatory properties than a comparison stimulus |
|
|
Term
| short-delayed conditioning |
|
Definition
| a classical conditioning procedure in which the CS is initiated shortly before the US on each conditioning trial |
|
|
Term
|
Definition
| movement toward and possibly contact with a stimulus that signals the availability of a positive reinforcer, such as food; also called autoshaping |
|
|
Term
| simultaneous conditioning |
|
Definition
| a classical conditioning procedure in which the CS and the US are presented at the same time on each conditioning trial |
|
|
Term
|
Definition
| same as compound-stimulus test |
|
|
Term
| temporal coding hypothesis |
|
Definition
| the idea that Pavlovian conditioning procedures lead not only to learning that the US happens but exactly when it occurs in relation the the CS; the CS represents (or codes) the timing of the US |
|
|
Term
|
Definition
| a trial in which the CS is presented without the US; this allows measurement of the CR in the absence of the UR |
|
|
Term
|
Definition
| a classical conditioning procedure in which the US is presented after the CS has been terminated for a short period |
|
|
Term
|
Definition
| the interval between the end of the CS and the start of the US in trace-conditioning trials |
|
|
Term
| unconditional or unconditioned response |
|
Definition
| a response that occurs to a stimulus without the necessity of prior training |
|
|
Term
| unconditional or unconditioned stimulus |
|
Definition
| a stimulus that elicits a particular response without the necessity of prior training |
