“…Likewise, afferent projections to the NAC exhibit previously nonreinforced stimulus). Our results showed that lesion to the shell mimicked the effects of hippocampal lesion (Kaye & Pearce, 1987a, 1987bSolomon, Lohr, & Moore, 1974) in that it disrupted latent inhibition, whereas core lesion had no such effect (Weiner et al, 1996; see also Tai et al, 1995). It has been often noted that NAC lesion-induced deficits are similar to those obtained following hippocampal lesions (Annett et al, 1989;Maldonado-Irizarry & Kelley, 1995;Reading & Dunnett, 1991;Schacter, Yang, Innis, & Mogenson, 1989;Seamans & Phillips, 1994; but see Sutherland & Rodriguez, 1989).…”

The effects of bilateral electrolytic lesions of the "shell" subterritory of the nucleus accumbens in the rat were examined on 2 tasks known to be sensitive to hippocampal damage. Experiment 1 tested the effects of shell lesion on delayed non-matching-to-sample (DNMS) task in a T-maze. The maze was rotated 180° after the end of acquisition. Experiment 2 used a 4-arm baited, 4-arm unbaked, 8-arm radial-maze task and its reversal. Shell lesion led to impaired acquisition of DNMS in a T-maze and of 4-arm baited, 4-arm unbaited, 8-arm radial maze tasks, suggestive of mnemonic deficits. Following analysis of animals' choice pattern in both tasks, the deficit was interpreted as being largely due to an extensive use of response strategy. The results suggest that the inappropriate use of response strategy by shell animals was a result of their inability to switch from initial response strategy to a later, more appropriate, memory-dependent strategy.

“…For example, if an animal is repeatedly exposed to a series of tones, these tones lose their capability to enter into associations with other stimuli, such as food or shock, or responses such as shuttle avoidance. The preexposed stimuli are retarded in the subsequent development of both excitatory and inhibitory conditioning and show no evidence of conditioned inhibition in summation test procedures (Reiss & Wagner, 1972;Rescorla, 1971; Solomon, Lohr, & Moore, 1974). The development of LI is considered to reflect a process of learning not to attend, to ignore, or tune out irrelevant stimuli (Lubow, Weiner, & Schnur, 1981;Mackintosh, 1973;; Moore, 1979;Wagner & Rescorla, 1972).…”

Latent inhibition (LI) is a behavioral paradigm in which repeated exposure to stimuli not followed by meaningful consequences renders these stimuli ineffective for subsequent learning. The development of LI is considered to reflect learning not to attend, to ignore, or tune out irrelevant stimuli. The present study investigated the differences in the development of LI between handled and nonhandled males and females. Infantile handled (days 1-22) and nonhandled, male and female Wistar rats were tested in maturity in the LI paradigm, using a conditioned emotional response (CER) procedure. The procedure consisted of three stages: preexposure, in which the to-be-conditioned stimulus, tone, was presented without being followed by reinforcement; acquisition, in which the preexposed tone was paired with shock; and test, in which LI was indexed by animals' suppression of licking during tone presentation. Handled animals exhibited less conditioned suppression as compared to nonhandled animals. LI was obtained in both the handled and the nonhandled females, but only the handled males showed the LI effect. Nonhandled males failed to develop LI. These results replicate our previous findings on LI in conditioned avoidance in demonstrating that: the effects of handling are evident in learning tasks that do not involve motivational-emotional variables, i.e., learning to ignore irrelevant stimuli; handling differentially affects males and females; the nonhandling procedure has deleterious consequences on adult behavior.

“…An alternative method to measuring conditioned inhibition is summation (e.g., Rescorla, 1969Rescorla, , 1971Solomon et al, 1974).). In the summation technique, a stimulus was first trained to become a conditioned inhibitor.…”

The purpose of this monograph is to examine the relationship between a particular artificial neural network, the perceptron, and the Rescorla-Wagner model of learning. It is shown that in spite of the fact that there is a formal equivalence between the two, they can make different predictions about the outcomes of a number of classical conditioning experiments. It is argued that this is due to algorithmic differences between the two, differences which are separate from their computational equivalence.A peer-reviewed monograph published by Comparative Cognition and Behavior Reviews on behalf of the Comparative Cognition Society.
