Hcl Solution

The 1 trial conditional pairing of a novel taste (HCl) solution with drug-induced illness (ip injection of cyclophosphamide) induces taste aversions in rats. This aversion is retained after intervals of 15, 45, or 90 days, even when the animals have had experience with similar tastes during the retention interval.

The current study aimed at comparing the effect of three placements of the re-exposure episodes on memory retention (interpolated-small, interpolated-medium, postponed), depending on whether retrieval practice or re-reading was used, and on retention interval (one week vs one month).

Experimental Word

Following a proaction paradigm, 670 Ss were trained with two lists containing five of the secondary associates (R2) to Russell-Jenkins stimulus words, and were tested 2 min., 20 mm., 2 days, or 28 days later for retention of the second list. During recall, half of the Ss were administered the five stimulus words corresponding to the five R2 words of the second list (stimulated condition), and half did not receive the stimulus words (not-stimulated condition). The stimulus words were divisible into three categories, in effect varying the cultural associative probabilities at each retention interval. Altogether, there were 24 groups completing a 4 × 2 × 3 factorial design. The retention of R2s decreased with time and the effect of stimulation was to raise their level of production above groups not so stimulated. As R2s decreased with time, intrusions of R1s (primaries) and Ra-nS (sum of Ra to R n) became more numerous where the cultural probabilities suggested this ought to happen. After 28 days, Ss still showed strong evidence of the training exposure but performance was more like that of free-associating Ss than that of shorter retention groups. In the not-stimulated condition, intrusions from unidentified sources (classified as Remainder) were more numerous the longer the retention interval. Collectively, these data support the conclusion that the amount of proactive interference via specific pre-experimental word-word habits increases as a function of time. An item analysis suggested a monotonic pattern of rs for forgetting under stimulated conditions, but not under conditions of free recall. This was interpreted to mean that forgetting when stimulated was more a process of complication than simplification and resembles a process sometimes found in motor-skills retention. Other correlational analyses proved useful tools for describing forgetting; questions pertaining to the behavior of items were quite as intriguing as those about Ss. Also, more variance could be accounted for after long than short retention intervals.

Marked Drop

The experiment studied the separate effects of sleep and time period of retention interval on forgetting. A free recall task was given to independent groups of subjects either at night or in the morning, and a second recall demanded 5 h later, after an intervening period of sleeping or waking activity. Oral body temperatures (BT) were measured at each session. The data were analysed in terms of (a) immediate recall at test 1, and (b) amount forgotten from test 1 to test 2. Immediate recall was higher for morning groups, in agreement with previous findings, serial position analysis indicating that the effect is confined to enhancement of the primary memory component. Long-term retention was higher over the night interval, irrespective of sleeping conditions, though having slept at night produced better retention than having stayed awake. Sleep during the morning was not effective in reducing forgetting. BT showed a marked drop for both night groups and rise for day groups over the retention interval. Alternative explanations for the classical sleep/memory findings are suggested in terms of (a) differential effects of sleep stages on memory, and (b) the underlying diurnal variation in BT and other processes.

Sequential Information

A single S learned a random sequence of 1,152 digits in 34½ hr. with the aid of a prelearned phonemic recoding system, while he was able to learn only one-third of that length without phonemic recoding in the same period of time. After a 3-mo. retention interval, S remembered two-thirds of the learning sequence, while in the control condition there was no evidence of recall. Utility of multiple recoding of binary sequential information was demonstrated. Results were compared with previous findings on phonemic recoding. Practical applicability of phonemic recoding of sequential digital information was suggested.

4 normal and 4 forebrain-ablated fish were food-reinforced for correct choice in a circle-square discrimination task; both groups readily learned the task. When the fish were tested after 8 days of a practice-free retention interval, both groups performed equally well and at the same level as their earlier asymptote. The results of this study indicate that long-term memory function of teleosts is not affected by forebrain ablation.
