Chapter 3: Pavlovian Conditioning Flashcards
Backward conditioning
A Pavlovian conditioning procedure in which the US precedes the CS. (C’. forward chaining.)
Blocking
Failure of a stimulus to become a CS when it is part of a compound stimulus that includes an effective CS. The effective CS is said to block the formation of a new CS. (C’. overshadowing.)
Classical conditioning
The procedure of pairing a neutral stimulus (typically referred to as the CS) with a US. Also called Pavlovian or respondent conditioning.
Compound stimulus
Two or more stimuli presented simultaneously, often as a CS.
Conditional reflex
A reflex acquired through Pavlovian conditioning and consisting of a conditional stimulus and a conditional response. (C’. unconditional reflex.)
Conditional response (CR)
The response part of a conditional reflex; the response elicited by a conditional stimulus. Often called conditioned response.
Conditional stimulus (CS)
The stimulus part of a conditional reflex; the stimulus that elicits a conditional response. Often called conditioned stimulus.
Contiguity
Nearness of events in time (temporal contiguity) or space (spatial contiguity).
Contingency
A dependency between events. An event may be stimulus contingent (dependent on the appearance of a stimulus) or response contingent (dependent on the appearance of a behavior).
CS+
In Pavlovian discrimination training, the stimulus that is regularly paired with a US. (C’. CS.)
CS-
In Pavlovian discrimination training, the stimulus that regularly appears in the absence of the US. (C’. CS+.)
Delayed conditioning
A Pavlovian conditioning procedure in which the CS starts before, and then overlaps with, the US.
A Pavlovian conditioning procedure in which the CS starts before, and then overlaps with, the US.
Extinction
1) In Pavlovian conditioning, the procedure of repeatedly presenting a CS without the US. (2) In operant training, the procedure of withholding the reinforcers that maintain a behavior. (C’. forgetting.)
Higher-order conditioning
A variation of Pavlovian conditioning in which a stimulus is paired, not with a US, but with a well-established CS.
Interstimulus interval (ISI)
The interval between the CS and US. The ISI is a measure of contiguity in Pavlovian conditioning.
Latent inhibition
In Pavlovian conditioning, the failure of a CR to appear as a result of prior presentation of the CS in the absence of the US.
Overshadowing
Failure of a stimulus that is part of a compound stimulus to become a CS. The stimulus is said to be overshadowed by the stimulus that does become a CS. (C’. blocking.)
Pavlovian conditioning
See classical conditioning.
Pseudoconditioning
The tendency of a neutral stimulus to elicit a CR when presented after a US has elicited a reflex response. Pseudocondtioning is apparently due to sensitization.
Rescoria-Wagner model
A theory of Pavlovian conditioning based on the assumption that the amount of learning that can occur on a particular trial is limited by the nature of the CS and US and the amount of learning that has already occurred. It is expressed by the equation ΔVn = c (λ Vn 1).
Respondent conditioning
See Pavlovian conditioning.
Sensory preconditioning
A procedure in which two neutral stimuli are paired, after which one is repeatedly paired with a US. If the other stimulus is then presented alone, it may elicit a CR even though it was never paired with the US.
Simultaneous conditioning
A Pavlovian conditioning procedure in which the CS and US occur together in time.
Spontaneous recovery
The sudden reappearance of a behavior following its extinction.
