Facilitation of the conditioning of a novel stimulus because of the presence of a previously conditioned stimulus; this is a challenge to the Rescorla-Wagner model
augementation; contra-blocking effect
intereference with the conditioning of a novel stimulus because of htep resence of a previously conditioned stimulu
blocking effect
idea that conditioned responding depends on a comparison between the associative strength of the CS and associative strength of other contextual cues present during training of the target CS
comparator hypothesis
conditioned response similar to the unconditioned homeostatic reactions that are elicted by US
conditioned homeostatic-response
conditioning procedure that reverses the organism's previous response to a stimulus; reponse animal makes to CS can be reversed by pairing this stimulus with a US that promotes the opposite type of reaction
interference with conditioning produced by repeated exposures to the CS before the conditioning trials
CS-preexposure effect; latent-inhibition effect
the significance or noticeability of a stimulus to the organism
stimulus salience
procedure in which perviously cconditioned stimulus is used to condition a new stimulus
higher-order conditioning
procedure in which one biologically weak stimulus CS1 is paried with another biologically weak stimulus CS2; Then cs1 is conditioned with an unconditioned stimulus and in a lter test cs2 will elicit the conditioned response even though cs2 was never paired with the unconditioned stimulus
sensory preconditioning
phsyiological mechanisms that serve to maintain critical aspects of the body within acceptable limits
develops when repeated administrations of a drug have profressively less effect; in conditioning, could be that drug cues become associated with US attenuate druge effects, and CR counteracts drug effects, which is why it develops
drug tolerance
learning of an association btween a stimulus and a response; conditioning establishes a new stimulus-response connection between CS and CR, Watson
S-R learning
learning of an assocation between two stimuli; subects respond to CS not because it elicits a CR but because it activates a representation of the US; Tolman
S-S learning
reduction i nthe attractiveness of an unconditioned stimulus, usually achieved by aversion conditioning or satiation
US devalutaion
idea that conditioned responding depends on how long the organism has to wait for the US in the presence of the CS compared to how long the organism has to wait for th US in the situation irrespective of the CS; CS is informatitve if the subject spends less time waiting for the US (trial duration) when the CS is present than in the experimental situation irrespective of the CS (intertrial)
relative waiting time hypothesis
interference with conditioning produced by repeated exposures to the undoncitioned stimulus before the conditioning trials
US-preexposure effect
idea that the outcome of classical conditioning is that organisms respond to the conditioned stimulus in the same that they respond to the unconditioned stimulus; wrong bcause rat example - not same response
stimulus substitution
omitting the US or reinforcer; involves repeated presentations of the CS by itself; CR usually declines
decline in conditioned responding that may ocur because of the passage of time
recovery of acquisiton performance when the contextual cues present during extinction are changed
recovery of excitatory responding to an extinguished stimulus produced by exposures to the unconditioned stimulus
CS if informative about the occurrence of the US only if the subject has to spend less time waiting for hte US when then CS is present than in the experimental situation
relative time hypothesis
