A total of 451 adults participated in 2 studies of the causes of age differences that occur in cognitive performance when tasks increase in complexity. Results support the hypothesis that more complex cognitive tasks place greater demands on a working memory resource that declines as age increases. (LB)

A theory of visual information acquisition and visual memory is described that conjoins two models that have been used to describe low-level perceptual and higher level cognitive processes. Six experiments with 21 adult observers generally support the theory, although some weakness is discussed. (SLD)

Describes research on memory in preschool children. Each child was studied for scene and list memory. Domain-specific and general knowledge were not found to be strongly related to memory performance. Object typicality did not have a strong effect on memory, but size did. (GH)

The addition of idiosyncratic features to individual members of an artificially constructed category enhanced specific item memory among 13 month olds, but not among 10 month olds. Discussion of findings focuses on their theoretical implications and the nature of the age difference. (RH)

New research findings on memory and learning systems have implications for continuing medical education in terms of format and length of learning activities, age of learners, and psychological factors such as stress and mental fatigue. (SK)

Investigates expository text macroprocessing and its relationship to working memory and school achievement by using a hierarchy-rating test. Indicates that the ability to identify expository text topics and main points are connected to Working Memory (WM). Finds that hierarchy-rating and multiple-choice task are strongly related to school…

Discusses work by Arthur Jensen in addition to his well-known work on the genetics of intelligence. Includes studies of learning, memory, the cumulative-deficit hypothesis, Spearman's hypothesis, and the speed of information processing. (SLD)

This study compared 19 students with learning disabilities (LD) in grades 6 and 8 with their nondisabled peers on the free recall of science passages when differences in passage understanding and domain vocabulary were controlled. Results suggested that the poorer performance of LD students might be the result of the inability to understand and…

Three experiments manipulated 3-month-olds' attention to different components of a training display and assessed the effect on retention. Results suggested that increasing or decreasing attention to an item during encoding produces a corresponding increase or decrease in memorability. Findings were consistent with a levels-of-processing account…

This study compared working memory in 28 high-functioning autistic individuals (ages 7-18) with that of 30 individuals with Tourette Syndrome or typically developing. No group differences were found. Performance was significantly correlated only with age and IQ. Results suggest that working memory is not an executive function seriously impaired in…

Addresses how existing theories of implicit cognition may contribute to the understanding of spelling development. Reviews adult literature on implicit memory and implicit learning that may be applied to spelling development. Presents a multilevel model of representational redescription from which to investigate the interrelation of implicit and…

Explores the fundamental principles of memory, eyewitness accuracy, and police questioning techniques in witness identification in a criminal case. Studies the details of an actual series of attacks and the subsequent police investigation to illustrate that memory is a reconstructive process rather than an accurate recording of events. (Author/ASK)

Research evidence indicates that self-report imagery ability is psychometrically distinct from objective, spatial test measures. One hypothesis put forward in the literature to explain this finding is that the nature of the stimulus is important. The aim of this article was to examine the relation between spatial abilities and measures of visual…

By understanding the different types of memory, the neurophysiology of brain chemical and anatomical changes associated with memory, and the ways to enhance the memory process, teachers can utilize proven technique--and develop their own--to guide students over that bleak terrain of memorization. From simplest recall of awareness, memory skills…

Four experiments explored the interrelations between working memory, attention, and eye movements. Observers had to identify a tilted line amongst vertical distractors. Each line was surrounded by a colored shape that could be precued by a matching item held in memory. Relative to a neutral baseline, in which no shapes matched the memory item,…
