In several other conditioning preparations, after a conditioned stimulus (CS) is conditioned and extinguished, reexposure to the unconditioned stimulus (US) by itself can reinstate the extinguished conditioned response. Reinstatement has been widely studied in fear and appetitive Pavlovian conditioning, as well as operant conditioning, but its status in taste aversion learning is more controversial. Six taste-aversion experiments with rats therefore sought to discover conditions that might encourage it there. The results often yielded little to no evidence of reinstatement, and we also found no evidence of concurrent recovery, a related phenomenon in which responding to a CS that has been conditioned and extinguished is restored if a second CS is separately conditioned. However, a key result was that reinstatement occurred when the conditioning procedure involved multiple closely spaced conditioning trials that could have allowed the animal to learn that a US presentation signaled or set the occasion for another trial with a US. Such a mechanism is precluded in many taste aversion experiments because they often use very few conditioning trials. Overall, the results suggest that taste aversion learning is experimentally unique, though not necessarily biologically or evolutionarily unique.

The current experiments use the compound test in a continuous outcome allergist task to assess the role of uncertainty in associative change, using two different manipulations of uncertainty: outcome uncertainty (where participants are uncertain of the level of the outcome on a particular trial) and causal uncertainty (where participants are uncertain of the contribution of the cue to the level of the outcome). We replicate Rescorla's compound test results in the case of both associative gains (Experiment 1) and associative losses (Experiment 3) and then provide evidence for greater change to more uncertain cues in the case of associative gains (Experiments 2 and 4), but not associative losses (Experiments 3 and 5).

This rule is well supported in studies with nonhumans. The present study was conducted to test whether it also applies to human contingency learning. In Experiment 1, participants were exposed to rapid streams of trials. Sensitivity to the cue-outcome contingency varied with both intertrial interval (ITI, which captures C) and cue duration, but the C/T rule was not respected, notably because the effect of ITI was much larger than the effect of cue duration. Experiment 2 showed that mere suppression of verbal strategies did not alter the magnitude of the ITI effect. Experiment 3 replicated Experiment 1 but with cue duration and ITI varied between 1,000 and 3,000 ms instead of between 100 and 1,000 ms. Performance was insensitive to both cue duration and ITI. This was not the consequence of Experiment 3 only varying the cue duration to ITI ratio by a factor of 3; in Experiment 4 where the cue duration was 100 ms, a 300-ms ITI was sufficient to observe an ITI effect. The lack of an ITI effect with a 1,000-ms cue and an ITI varying between 1,000 and 3,000 ms was replicated in Experiment 5. These results are discussed in light of how processes underlying associative learning might break down when events occur very rapidly.

Two hypotheses have been proposed concerning the role of the sample stimulus. According to Hull (1952), the sample and the response to the correct comparison form a stimulus-response chain. According to Skinner (1938), however, the sample serves as an occasion setter, setting the occasion for the choice of the correct comparison stimulus. In a conditional discrimination, if the sample stimulus forms part of a stimulus-response chain, then presenting the sample in the absence of the comparison stimuli should weaken the association. If the sample serves as an occasion setter, however, presenting the sample alone should not weaken its occasion-setting ability. In two experiments we tested these predictions. In Experiment 1, following conditional discrimination training with vertical and horizontal line samples and red and green comparison stimuli, we found that the presentation of the samples without the comparison stimuli (followed sometimes by a reinforcer) had little effect on conditional discrimination accuracy. In Experiment 2, two different houselights served as samples. When we presented the samples without comparison stimuli and without the reinforcers we found similar results.

One largely successful account of the PREE, known as sequential theory (Capaldi, 1966), suggests that, when subjects are partially reinforced, they learn that memories of sequences of nonreinforced trials are associated with subsequent reinforcement. This association helps to maintain responding (i.e., delay extinction) when the subjects experience nonreinforced trials during extinction. Sequential theory's explanation of the PREE hinges on subjects learning sequences of nonreinforced trials during acquisition. However, direct evidence for such sequential learning is not available in previous studies of the PREE where animals are trained with multiple sequences of different lengths that are randomly intermixed and, therefore, cannot anticipate whether a given trial will be reinforced during acquisition. The current study conducted two experiments that trained rats with a single fixed trial sequence to provide evidence of sequential learning during conditioning, and then observe its effect on the PREE. Under one condition the rats did learn about the fixed sequence but did not subsequently show a PREE, whereas other rats that did show a PREE had not learned the trial sequences during conditioning. Therefore, contrary to sequential theory's prediction, our result suggests that learning about the trial sequence is neither necessary nor sufficient for the PREE. We suggest that the PREE may instead depend on uncertainty about whether the conditioned stimulus will be reinforced.

This partial reinforcement extinction effect (PREE) is one of the best-known phenomena in associative learning but defies ready explanation by associative models which assume that a partial reinforcement schedule will produce weaker conditioning that should be less resistant to extinction. The most popular explanation of the PREE is that, during partial reinforcement, animals learn that recent nonreinforced (N) trials are associated with subsequent reinforcement (R), and therefore the presence of N trials during extinction serves to promote generalization of conditioning to extinction. According to sequential theory (Capaldi, 1966), animals can encode whole sequences (runs) of N trials and associate their memory of the sequence with subsequent R. The length of these N sequences during conditioning affects how long the animal will continue to respond during extinction. The present experiment used Pavlovian magazine approach conditioning with rats to test two predictions of this theory. Consistent with sequential theory, the PREE was sensitive to the length of the N sequence: conditioning with long sequences (runs of 3-5 N trials) produced a stronger PREE than conditioning with short sequences (runs of 1 or 2) even when the total number of N and R trials was held constant. Surprisingly, there was no PREE among rats trained with the short sequences. Moreover, contrary to the theory's prediction, interrupting the long N sequences with reinforced trials of a different conditioned stimulus did not affect the subsequent PREE. I conclude that uncertainty about reinforcement, rather than the memory of N sequences per se, is a key factor in the development of the PREE.
