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.
Stimulus-substitution theory
In Pavlovian conditioning, the theory that the CS substitutes for the US. Assumes that the CR is essentially the same as the UR.
Test trial
In Pavlovian conditioning, the procedure of presenting the CS on some occasions without the US to determine whether learning has occurred.
Trace conditioning
A Pavlovian conditioning procedure in which the CS begins and ends before the US is presented.
Unconditional reflex
A synonym for reflex. An unconditional reflex consists of an unconditional stimulus and an unconditional response. (See refl ex; C’. conditional reflex.)
Unconditional response (UR)
The response elicited by an unconditional stimulus. Often called an unconditioned response. (C’. conditional response.)
Unconditional stimulus (US)
The stimulus that elicits an unconditional response. Often called an unconditioned stimulus. (C’. conditional stimulus.)
Intertrial interval
The interval separating the trials of a discrete trial procedure.
