Chapter 4 Flashcards
acquisition
the process of developing and strengthening a conditioned response through repeated parings of a neutral stimulus (NS) with an unconditioned stimulus (US)
asymptote
the maximum amount of conditioning that can take place in a particular situation is known as the asymptote of conditioning
(more intense USs produce stronger and more rapid conditioning than do less intense US, more intense NSs result in stronger and more rapid conditioning than do less intense)
extinction
the conditioned response is weakened or eliminated when the conditioned stimulus (CS) is repeatedly presented in the absence of an unconditioned stimulus (US)
also refers to the procedure whereby this happens
spontaneous recovery
the reappearance of a conditioned response to a conditioned stimulus CS following a rest period after extinction
disinhibition
sudden recovery of a conditioned response during an extinction procedure when a novel (unfamiliar) stimulus is introduced
stimulus generalization
the tendency of a CR to occur in the presense of a stimulus that is similar to the CS
semantic generalizations
generalization of a conditioned response to verbal stimuli that are similar in meaning the CS
stimulus discrimination
the tendency for a response to be elicited more by one stimulus than another
experimental neurosis
experimentally produced disorder in which animals exposed to unpredictable events develop neurosis-like symptoms
high-order conditioning
the process whereby a neutral stimulus that is associated with a CS (rather than a US) also becomes a CS
sensory preconditioning
one stimulus is conditioned as a CS, another stimulus with which it was previously associated can also become a CS.
US revaluation
a process that involves the post-conditioning presentation of the US at a different level of intensity, thereby altering the strength of response to the previously conditioned
overshadowing
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 less salient member
blocking
the phenomenon whereby the presence of an established CS interferes with the conditioning of a new CS.
occasion setting
a procedure in which a stimulus (known as an occasion setter) signals whether a CS is likely to be followed by a US and thereby controls whether the CS will elicit a CR
