“…Overall, these results extend the research of Bower and Grusec (1964) and Mellgren and Ost (1969), who showed that Pavlovian conditioning can facilitate subsequent acquisition of discrimination training, to the use of Pavlovian conditioning to a single odor stimulus to facilitate acquisition of an odor-discrimination in dogs. To further confirm that Pavlovian conditioning may be a simple way to facilitate subsequent acquisition of an odor discrimination, we extended the finding of Experiment 1 to an AX vs BX discrimination using a within-subjects design.…”

“…The present results suggest that when the odor is conditioned as an appetitive CS, it may more readily become an operant discriminative stimulus. This mechanism is similar to the Pavlovian to operant transfer of stimulus control proposed by Bower & Grusec (1964) and Mellgren and Ost (1969). Our discrimination training was an explicit operant contingency in which the reinforcer was delivered contingent on digging in the correct bin.…”

“…Rats in the consistent group learned significantly faster, outperforming the inconsistently trained rats. In a subsequent study Mellgren & Ost (1969) showed that rats trained consistently outperformed a group of rats without any prior exposure to the stimuli.…”

“…The former group developed appropriate discriminative responding more rapidly than did the group for which the stimulus relations were reversed . Mellgren and Ost (1969) confirmed this finding under similar conditions, and, by employing a control group which received water presentations during both stimuli before discriminative instrumental training, showed that the effect was due both to facilitation of performance in the group which experienced consistent stimulus-reinforcer relations and interference in the group in which the relations were reversed. …”

Independent groups of rats underwent various pretraining vrocedures involving key light illumination and presentation of food before introduction of instrumental conditioning in which food reinforcement was immediately contingent upon pressing the illuminated key. Key illumination followed immediately by food presentation produced facilitation of subsequent acquisition of .instrumental reslJonding whiCh increased with 0, 10, 50, and 200 pretraining trials; the facilitative effect of 1,000 pairings of key illumination and food was no greater than that of 200 pairings. The facilitative effect of key illumination and food presentation upon subsequent instrumental learning was the same regardless of whether food presentations in pretraining immediately accompanined illumination offset or were delayed for 8 sec. Food presentations alone on 10 , 50, or 200 pretraining trials facilitated subsequellt instrumentallear,ling less than equivalent numbers of presentations of illumination and food, but 200 presentatio ns of fvod alone facilitated subsequent instrumental learning more than 0 pretraining trials.There have been several studies of the effects of response-independent palflngs of a stimulus and reinforcer upon subsequent appetitive instrumental discrimination learning. In a typical experiment, Bower and Grusec (1964) trained rats to press a lever for water. The lever then was removed and two tones were presented alternately. Water was periodically delivered during one tone presentation and not the other. The lever was then reintroduced, and discriminative instrumental training with the successively presented stimuli began. For some animals, response-contingent water reinforcement was delivered during presentation of the tone previously associated with water , and for others the discrimination was reversed . The former group developed appropriate discriminative responding more rapidly than did the group for which the stimulus relations were reversed . Mellgren and Ost (1969) confirmed this finding under similar conditions, and, by employing a control group which received water presentations during both stimuli before discriminative instrumental training, showed that the effect was due both to facilitation of performance in the group which experienced consistent stimulus-reinforcer relations and interference in the group in which the relations were reversed.

“…CER training, on the other hand, is a form of Pavlovian conditioning, since the presentation of the US (in this case shock) is independent of the subject's behavior. While there have been a number of studies reported in which Pavlovian differential conditioning was found to facilitate subsequent operant performance (Bower & Grusec, 1964; Mellgren & Ost, 1969;Ost & Mellgren, 1970;Trapold, Lawton, Dick, & Gross, 1968), in those experiments the same stimuli were used in both the Pavlovian and operant phases of the experiment. In the present study, the CER training involved different stimuli.…”

The effects of CER training on the acquisition of a successive operant discrimination

Following keypeck training to a chromatic stimulus, one group of pigeons was given CER training with a white vertical line superimposed on the key as the CS and shock as the US; a second group was given presentations of the CS only; a third group received shock only with no CS preceding it on the key; a fourth group received only the keypeck training with the chromatic stimulus. All groups then received identical training on a successive operant discrimination involving auditory stimuli. The CER subjects learned this discrimination faster than did subjects in the other three groups, which did not differ. The results extend the generality of conditions which facilitate the acquisition of successive operant discriminations.
