A Study of Retention of Verbal Material. Final Report.
Thompson, Charles P.
This research project investigated some of the characteristics of primary and secondary memory. In the primary research, subjects were given a list of words followed by an interpolated task. The data of interest were the recall for terminal items in the list. Using this procedure, the researchers have demonstrated negative recency in initial recall and have provided evidence that this effect is attributable to store-specific interference in primary memory. They have also demonstrated that this effect is a necessary consequence of the procedure rather than the result of a strategy on the part of the subject. In the secondary memory research, interest was focused on procedures in which subjects learned categorized lists. It was demonstrated that subjects learned how to cluster over successive lists and that this effect probably resulted from an increase in the post-item latency used as a criterion to exit a category and search another during recall. It has also been demonstrated that ability to recall is correlated with amount of clustering. Another set of results came from experiments demonstrating that repeated-category interference can be eliminated through the use of subcategorization or adjectival modification. (WR)
