Term Memory

A total of 300 university students were presented a brief list of non-alphanumeric items and instructed to recall immediately either the items (free recall, FR), the order in which the items were presented (order recall, OR), or both (serial recall, SR). Presentation rate and retention interval were additional experimental variables in Exp. I and II, respectively. In both experiments significant differences in recall were found between FR conditions and the remaining two, which did not differ from each other. More items were recalled at the slow than fas: rate. Retention interval was not a significant variable. Results suggest that retention will improve when order information is eliminated from recall (Brown, 1958), that the recall of item and order information involve at least partially independent memory processes, and that, while the recall of items may proceed independently of the recall of their order, the converse is not true.

Two Independent Variables

Two experiments done with a short-term memory paradigm examined the influence of shifts in the starting position on the reproduction of kinesthetic location (Exp. 1) and on distance cues (Exp. 2). We assessed possible causes of the systematic pattern of undershooting and overshooting as related to the shift in the starting position. In each experiment, two groups of 10 students were given 25 trials, and each had criterion and reproduction tasks involving linear-positioning movements with a 10-sec. retention interval. Each experiment had two independent variables, the group of subjects and the shift in the starting position. The two groups differed in the possible sources of information, the distance moved (Exp. 1) or the end-location (Exp. 2), which were assumed to cause undershooting and overshooting during reproduction. Analysis showed that the information about the distance moved may produce undershooting and overshooting in reproduction of the end-location (Exp. 1). Also, the information about the end-location may produce undershooting and overshooting in reproduction of the distance moved (Exp. 2). The findings were further evidence of interference between location and distance cues in motor short-term memory.

Trigrams were presented visually or auditorily and followed by a 12 s retention interval filled with shadowing numbers or letters. Auditory memory letters followed by letter shadowing were recalled less than auditory memory letters followed by number shadowing or visual memory letters followed by either type of shadowing. The latter three conditions did not differ among themselves. An analysis of the recall intrusions suggested that forgetting of auditory memory letters followed by letter shadowing was caused mainly by a confusion between covert rehearsals and shadowing activity, while forgetting in the other three conditions was caused primarily by proactive interference from earlier memory trials.

Counting Task

An experimental study of short-term memory for lists of familiar English words is reported. Lists of 10, 20, and 30 unrelated words were presented at a 1-sec. rate. Retention was measured by free recall after intervals of 0, 15 and 30 sec. A counting task was used to prevent rehearsal during the retention interval. The absolute level of recall increased with length of list whereas the percentages retained showed the reverse trend. The recall scores decreased steadily as a function of retention interval, with the rates of forgetting comparable for the three lengths of list. The decline in the amount recalled was due in large measure to the loss of the terminal items in the list. Consequently, the pronounced recency effect present on the immediate test of recall was progressively reduced as a function of time. By contrast retention of the initial part of the list was relatively stable. These variations in rate of forgetting are attributed to differences among serial positions in susceptibility to proactive inhibition.

Memory For Duration

This study examined the short-term retention characteristics of temporal information about visually guided movements. Subjects attempted to recall a preselected movement of a particular duration either immediately or after an unfilled or filled retention interval. Subjects did not benefit from an opportunity to rehearse information about duration of movement over the interval. This finding supports a decay model of forgetting for temporal information about visually guided movements.

The Way

The Brown-Peterson paradigm was used to study the way colors and color names are encoded in memory. Three colored strips or the names of the 3 colors were presented on each of 4 trials. The 30-sec. retention interval was filled with number counting. Two control groups received the same material, either colors or names of colors, on all 4 trials. Two experimental groups were shifted from color names to colors or from colors to color names on test trial 4. The results indicated that (1) proactive inhibition developed to both colors and color names, (2) recall of colors was superior to color names, and (3) release from proactive inhibition was found in the group shifted from color names to colors but not in the group shifted in the opposite direction. The results were discussed in terms of the dual-coding hypothesis developed by Paivio.

Functional Integrity

We investigated the role of the human medio-temporal complex (hMT+) in the memory encoding and storage of a sequence of four coherently moving RDKs by applying repetitive transcranial magnetic stimulation (rTMS) during an early or late phase of the retention interval. Moreover, in a second experiment we also tested whether disrupting the functional integrity of hMT+ during the early phase impaired the precision of the encoded motion directions. Overall, results showed that both recognition accuracy and precision were worse in middle serial positions, suggesting the occurrence of primacy and recency effects. We found that rTMS delivered during the early (but not the late) phase of the retention interval was able to impair not only recognition of RDKs, but also the precision of the retained motion direction. However, such impairment occurred only for RDKs presented in middle positions along the presented sequence, where performance was already closer to chance level. Altogether these findings suggest an involvement of hMT+ in the memory encoding of visual motion direction. Given that both position sequence and rTMS modulated not only recognition but also precision of the stored information, these findings are in support of a model of visual short-term memory with a variable resolution of each stored item, consistent with the assigned amount of memory resources, and that such item-specific memory resolution is supported by the functional integrity of area hMT+.
