autoshaping Same as sign tracking.backward conditioning A procedure in which the conditioned stimulus is
presented shortly after the unconditioned stimulus on each trial.
compound-stimulus test A test procedure that identifies a stimulus as a conditioned inhibitor if that stimulus
reduces the responding elicited by a conditioned excit- atory stimulus. Also called summation test.
conditional or conditioned response (CR) The response that comes to be made to the conditioned stimulus as a
result of classical conditioning.
conditional or conditioned stimulus (CS) A stimulus that does not elicit a particular response initially, but
comes to do so as a result of becoming associated with an unconditioned stimulus.
conditioned emotional response (CER) Suppression of positively reinforced instru- mental behavior (e.g., lever
pressing for food pellets) caused by the presentation of a stimulus that has become associated with an aversive
stimulus. Also called con- ditioned suppression.
conditioned suppression Same as conditioned emotional response.conditioning trial A training episode
involving presentation of a conditioned stimulus with (or without) an unconditioned stimulus.
CS-US interval Same as interstimulus interval.
evaluative conditioning Changing the hedonic value or liking of an initially neutral stimulus by having that
stimulus associated with something that is already liked or disliked.
explicitly unpaired control A procedure in which both conditioned and uncondi- tioned stimuli are presented,
but with sufficient time between them so that they do not become associated with each other.
inhibitory conditioning A type of classical conditioning in which the conditioned stimulus becomes a signal for
the absence of the unconditioned stimulus.
interstimulus interval The amount of time that elapses between presentations of the conditioned stimulus (CS)
and the unconditioned stimulus (US) during a classical conditioning trial. Also called the CS-US interval.
intertrial interval The amount of time that elapses between two successive trials. latency The time elapsed
between a stimulus (or the start of a trial) and the response that is made to the stimulus.
lick-suppression procedure Similar to the conditioned emotional response (CER), or conditioned suppression
procedure. However, instead of lever pressing for food serving as the behavior that is suppressed by conditioned
fear, the baseline is lick- ing a water spout by thirsty rats. The presentation of a fear-conditioned CS slows down
the rate of drinking.
magnitude of a response A measure of the size, vigor, or extent of a response.
object learning Learning associations between different stimulus elements of an object.
probability of a response The likelihood of making the response, usually represented in terms of the percentage
of trials on which the response occurs.
pseudo-conditioning Increased responding that may occur to a stimulus whose presen- tations are intermixed
with presentations of an unconditioned stimulus (US) in the absence of the establishment of an association
between the stimulus and the US.
