CS habituation produces a “latent inhibition effect” but no active “conditioned inhibition”

Classical conditioning as a nonstationary, multivariate time series analysis: A spreadsheet model

“…In the model, this retarding effect is not "inhibitory" in nature; it does not involve the animal's learning that the CS predicts a reduction in the rate of US occurrence. Thus, the model predicts that the retardation of conditioning by prior CS exposure will be observed whether the subsequent conditioning phase involves excitatory or inhibitory conditioning, which is what has been found (Reiss & Wagner, 1972).…”

“…The model predicts many experimental results that have posed problems for past or present associative models of conditioning, including: (1) the effect of partial reinforcement on the rate of acquisition and the rate of extinction (Gibbon, Farrell, Locurto, Duncan, & Terrace, 1980); (2) the effect of the duty cycle (or ITIIISI ratio) on the rate of acquisition and its lack of effect on the rate of extinction (Gibbon, Baldock, Locurto, Gold, & Terrace, 1977); (3) blocking and overshadowing (Kamin, 1969); (4) the blocking effect of background conditioning (Rescorla, 1968); (5) the effects of having the "background" USs signaled by another CS (Robbins & Rescorla, 1989); (6) inhibitory conditioning when the CS and US are explicitly unpaired; (7) the predictive sufficiency results of Wagner, Logan, Haberlandt, and Price (1968), in which the CS that accounts for more of the variance in US occurrence is the CS that gets conditioned; (8) inhibitory conditioning in overpredictionexperiments (Kremer, 1978); and (9) the noninhibitory retarding effect of a "latent inhibition" training phase on the rate of subsequent conditioning (Reiss & Wagner, 1972).…”

A componential view of configural cues in generalization and discrimination in Pavlovian conditioning

“…The contribution of antagonistic orienting responses to response decrement under various conditions of stimulus change certainly deserves investigation. We are, however, impressed that Reiss and Wagner [10] observed a response decrement when a stimulus was added to a well-trained CS, even though the added stimulus was preexposed over 1000 time prior to CS conditioning; i.e. when it was unlikely to evoke an 'investigatory reflex'.…”

Role of the hippocampus in blocking and conditioned inhibition of the rabbit's nictitating membrane response.

“…There have been several recent experimental investigations of the latent inhibition phenomena in the rabbit nictitating membrane response (NMR) preparation (Reiss & Wagner, 1972;Siegel, 1972;Solomon et al, 1974 a & b) . In general these studies support the conclusion from other conditioning preparations (cf., Rescorla, 1971) Jarrard's (1973) proposal that the hippocampus is involved in motivational processes.…”
