Correlational analyses indicated that age of acquisition estimates, codability, and retrieval speed were highly related to each other and significantly related to most of the semantic dimensions. Regression analyses revealed that codability, meaningfulness, and imagery each contributed signficantly to the variance of retrieval speed. (Author)

Seven-, ten- and seventeen-year-olds (N=72) in control and experimental conditions were used to test the role of metamemory and metamemory activation in the development of mnemonic performance. Metamemory was found to be a necessary condition for mnemonic performance. Developmental differences were found. (Author/DB)

The cognitive processes of seven children solving arithmetic problems were accurately classified as reconstructive or reproductive according to the child's verbal report of his thought processes. Classifications of thought processes by means of verbal reports can also be used to improve the analysis of latencies. (SB)

The article discusses two subtests of the Detroit Tests of Learning Aptitude: the Disarranged Pictures subtest which measures visual perception, and Memory for Designs, which assesses recall and reproduction of abstract visual presentation. Diagnostic and prescriptive considerations are reviewed. (CL)

Retrieval and response criterion explanations of the effects of text organization on memory were tested in four experiments. More target information was freely recalled when it was high than when low in content structure. Retrieval cues reduced recall differences between information high and low in the structure. (Author/RD)

Results suggested that LD children suffer from a verbal mediational deficiency consistent with J. Flavell's mediation deficiency hypothesis. (Author)

The effect of presupposition on memory depends upon a restricted class of pragmatic conditions. If certain intended misleaders are introduced, presupposition does not enter into memory. This was shown with two experiments in which subjects "remembered" an accident differently, depending upon whether misleading facts were introduced.…

Two experiments tested a set of predictions regarding category definitions and categorization latencies. Neither prediction was supported by the experiment results, leading to the formulation of an alternative feature-based model of category definitions using the notion of a polymorphous concept. (Author/AM)

In motor skill performance and retention, the complexity of knowledge of results should interact appropriately with the child's processing rate, since children process information in short-term memory more slowly than adults, and their control processes (rehearsal, naming, grouping, and recording) become more efficient only with increased age. (JD)

Study concludes that short-term listening is apparently an information processing skill that differs importantly from short-term memory and is related not only to a "delivery" factor but also to ability in oral communication. (JMF)

Three studies examined early development of recall. Children between 2 years 9 months and 5 years of age were tested on nine-item lists containing three objects from each of three conceptual categories or nine objects for nine different conceptual categories. (Author/SS)

Assesses the long-term retention of conditioned operant footkicks by three-month-old infants. Views a conditioning analysis as a logical means by which to bridge the gap between animal and adult human models of memory. (Author/RH)

Immediate post-testing of high school students after they studied a prose passage improved their memory significantly. (JD)

High- and low-visualizing males, identified by the self-report VVIQ, participated in a memory experiment involving abstract words, concrete words, and pictures. High-visualizers were superior on all items in short-term recall but superior only on pictures in long-term recall, supporting the VVIQ's validity. (Author/SJL)

Restates A. D. Baddeley's hypothesis about the limited capacity for information processing: an individual's limited capacity to handle information (including production and storage), although presumably never reached in actual performance, exercises a definable constraint on performance. (RL)
