Discrimination of Recency in Children. Final Report.
Mathews, Mary Elizabeth
Two experiments comprised this study comparing the ability of children from ages 4 to 12 years to discriminate the order in which items from a previously presented sequence of stimuli had been presented. The hypotheses were that the discrimination of recency (DR) improves with age, that broader separations of test items are easier to discriminate than narrower ones, and that length of the stimulus list influences DR. In experiment one, 76 children were given six test lists of pictorial stimuli. After each list was presented, the subject was shown two of the pictures again and asked to state which one he had seen more recently. The lists consisted of seven or 12 items; either two or four items separated the pictures in question. Experiment two was similar to the first but involved 52 children and increased the separation between items on the testing phase to four and seven. Experiment two was conducted because performances on the first were generally poor. The results from the two experiments showed that DR improved with age and that performance improved when shorter lists and wider separations were used. (WD)
