Term
Acquisition
Definition
The process of developing and strengthening a conditioned response through repeated pairings of an NS (or CS) with a US.
Term
Blocking
Definition
The phenomenon whereby the presence of an established CS interferes with conditioning of a new CS.
Term
Compound Stimulus
Definition
A complex stimulus that consists of the simultaneous presentation of 2 or more individual stimuli.
Term
Disinhibituation
Definition
The sudden recovery of a response during an extinction procedure when a novel stimulus is introduced.
Term
Experimental Neurosis
Definition
An experimentally produced disorder in which animals exposed to unpredictable events develop neurotic-like symptoms.
Term
External Inhibition
Definition
A decrease in the strength of the conditioned response due to the presentation of a novel stimulus at the same time as the conditioned stimulus.
Term
Extinction
Definition
The process whereby a conditioned response can be weakened or eliminated when the CS is repeatedly presented in the absence of the US; also, the procedure whereby this happens, namely, the repeated presentation of the CS in the absence of the US.
Term
Higher-order Conditioning
Definition
The process whereby a neutral stimulus that is associated with a CS (rather than a US) also becomes a CS.
Term
Latent Inhibition
Definition
The phenomenon whereby a familiar stimulus is more difficult to condition as a CS than in an unfamiliar (novel) stimulus.
Term
Occasion Setting
Definition
A procedure in which a stimulus (known as an occasion setter) signals that a CS is likely to be followed by the US with which it is associated.
Term
Overshadowing
Definition
The phenomenon whereby the most salient member of a compound stimulus is more readily conditioned as a CS and thereby interferes with conditioning of the least salient member,
Term
Pseudoconditioning
Definition
A situation in which an elicited response that appears to be a CR is actually the result of sensitization rather than conditioning.
Term
Semantic Generalization
Definition
The generalization of a conditioned response to verbal stimuli that are similar in meaning to the CS.
Term
Sensory Preconditioning
Definition
In this phenomenon, when 1 stimulus conditioned as a CS, another stimulus with which it was previously associated can also become a CS.
Term
Spontaneous Recovery
Definition
The reappearance of a conditioned response to a CS following a rest period after extinction.
Term
Stimulus Discrimination
Definition
The tendency for a response to be elicited more by 1 stimulus than another.
Term
Stimulus Generalization
Definition
The tendency for a CR to occur in the presence of a stimulus that is similar to the CS.
Term
Temporal Conditioning
Definition
A form of classical conditioning in which the CS is the passage of time.
Term
US Revaluation
Definition
A process that involves the preconditioning presentation of the US at a different level of intensity, thereby altering the strength of response to the previously conditioned CS.
