“…Moreover, recent data collected in our laboratory establish that the capuchin monkey is capable of successful matching at delays of at least 4 min. Possibly, previous investigators (e.g., Jarrard and Moise, 1970;Scheckel, 1965) would have obtained results more consonant with ours had the delay interval been spent in darkness, although a definite conclusion on this score is precluded by the many differences in experimental procedures. In this connection, both Jarrard and Moise (1970) and Scheckel (1965) manipulated the delay interval by means of a titration technique in which the delay interval automatically increased or decreased in accordance with the subject's performance level.…”

Experiment 1 demonstrated that delayed matching-to-sample in the capuchin monkey was superior when the delay interval was spent in darkness rather than in moderate illumination. In contrast with previous studies in which the delayed-matching ability of primates appeared limited to 60 sec or less, in the dark condition all subjects showed above-chance matching at a 120-sec delay interval. Experiment 2 verified that darkness during the delay interval can facilitate delayed matching and provided evidence that the effective variable was the illumination level of the delay interval rather than change in illumination, which in Exp. 1 was confounded with illumination level.

“…Previous investigators have found the delayed-matching performance of primates to be rather limited (e.g., Jarrard and Moise, 1970; Scheckel, 1965). For example, the stumptail monkeys of the Jarrard and Moise study, although well practiced in delayed matching, performed very poorly at delay intervals of only 30 sec.…”

Six pigeons were trained in matching-to-sample using a titration procedure. Three of the pigeons began each session at a 60-sec intertrial interval. During the session, two consecutive correct responses reduced the intertrial interval by 2 sec, while a single error increased the intertrial interval by 2 sec. The 60-sec intertrial interval subjects worked toward the O-sec interval. Both groups acquired high matching accuracy. The groups differed in the distribution of errors within a session. The 60-sec intertrial interval subjects made fewer errors in the first half of a session than in the second half. The O-sec intertrial interval subjects made more errors in the first half of a session than in the second half of a session. Thus, the titration procedure may have some differential effects depending upon the initial levels of the variable being titrated.In the matching-to-sample task the subject is first presented with a sample stimulus. After responding to the sample stimulus, a set of comparison stimuli are presented. Then the subject is required to select the stimulus that corresponds to the sample. Many variables, such as schedules of reinforcement (Ferster, 1960), observing responses (Eckerman, Lanson, & Cumming, 1968), and time-out (Ferster & Appel, 1961), have been found to affect matching-to-sample performance. Holt and Shafer (1973) have shown that the intertrial interval also affects performance in matching-to-sample. They reported that pigeons on a O-sec intertrial interval failed to match beyond chance levels. For subjects on intertrial intervals longer than 0 sec, a change to the O-sec interval decreased matching performance.In the present experiment a titration procedure was employed to fmd the optimal intertrial interval. Schrier, Stollnitz, and Green (1963) reported that a titration procedure reduced training time, and that titration was superior to a gradual shaping procedure. Wunderlich (1971) showed how titration facilitated learning in retardates. By using the titration method in delayed matching-to-sample, Scheckel (1965) and Mello (1971) showed that the range of successful delayed matching for monkeys exceeded the delays reported in the literature.

“…The self-adjustment technique has been successfully applied in studies of scotopic and photopic sensitivity (Blough & Schrier, 1963;Schrier & Blough, 1966) and critical flicker frequencies (Symmes, 1962) application of this procedure has, however, involved positive reinforcement, which could make it less useful where the event used to change the threshold is aversive. This situation may lead to a failure to respond during, and for some time after, the occurrence of the aversive event.…”

“…The self-adjustment procedure developed by Bekesy (1947), Blough (1958), andScheckel (1965), provides a means of resolving these difficulties, since the S is constantly adjusting the stimulus value around the threshold level. The self-adjustment technique has been successfully applied in studies of scotopic and photopic sensitivity (Blough & Schrier, 1963;Schrier & Blough, 1966) and critical flicker frequencies (Symmes, 1962) application of this procedure has, however, involved positive reinforcement, which could make it less useful where the event used to change the threshold is aversive.…”
