Four experiments were conducted where words were recalled after presentation either in hierarchical fashion or in a matrix. The intention was to examine whether the original advantage for hierarchical retrieval systems could be duplicated for matrix systems, and if there was any particular advantage or disadvantage for either type of structure.…

Investigates three alternative explanations for why younger children benefit more than older children from the provision of category size information when recalling items from a categorized list. Subjects were 29 kindergarten and 30 third grade children. (MP)

The role of reversibility in children's comprehension and memory for sequences of pictures was investigated for children in preschool, kindergarten, and first and second grades. Bidirectionality in the ability to remember and infer antecedents and consequences was assessed. (JMB)

The extent to which students perform differently on recall, low-inference, and high-inference items on a reading comprehension test is explored in this research. Results indicate a significant difference between questions asking for recall and inference comprehension. (JMF)

A method for quantifying story retells, called proposition analysis, was used to study the reading comprehension performances of 34 learning disabled and normal fifth and sixth graders. Journal availability: see EC 112 927. (DLS) 927

Examines the verification of false sentences of the form "All S are P." It was found that the number of properties shared by the subject and predicate concept of the sentence was directly proportional to reaction time. These findings question the assumption that only property relations are prestored in memory. (Author/EJS)

As age and grade increased, recall on all tasks increased; subjects in grades three to six were also seen to have a fully developed Iconic Memory, while only sixth graders had a functionally developed Immediate Memory. (KR)

Analysis of the frequency and nature of error and post-error responses in serial choice reaction times of 84 children between 5 and 12 years essentially replicate findings in adults. (Author/MP)

In a list presented for study, the successive occurrences of a repeated item may appear either in adjacent or nonadjacent list positions. This research attempts to determine the relative size of this spacing effect, either for massed-presentation items (MP) or distributed-presentation items (DP), in long-term tests of retention as compared to that…

Attempts to provide empirical evidence for a functional correspondence between perception and imagination. Includes a perceptual-control condition in examining visual memory and imagery. (Author/RK)

Four experiments are reported investigating previous findings that speech perception interferes with concurrent verbal memory but difficult nonverbal perceptual tasks do not, to any great degree. (Editor)

Voluntary forgetting of a list of verbal items was tested under two conditions. Results show that both recall and recognition increase as a function of the spacing between the two occurrences under the Remember-Forget condition, but not under the Forget Forget-Remember condition. (Editor/RK)

Eighty-six adults serially recalled lists of visually presented consonant letters similar in auditory or visual features or dissimilar on both feature sets. There were significantly more errors at every auditory list position than at the corresponding visual and neutral list positions, which did not themselves differ. Positive correlation exists…

Interresponse time (IRT) data were used to investigate the hypothesis that the learning to cluster (effectively organizing presented material) phenomenon should be interpreted as the result of a retrieval strategy. A systematic increase of category exit criterion should produce an increase in clustering because more category words should be…

Attempts to measure the involvement of an active memory process in the storage of the memory stimulus and to determine if such involvement is necessary for obtaining a Posner effect, which suggest that visual memory is not damaged by distractor tasks. (Author/RK)
