The aim of the present study was partly to see whether the trade-off between item and attribute memory was a reliable phenomenon and partly to examine the strategies used by subjects in this task. (Author/RK)

A major error in cognitive science has been to suppose that the meaning of a representation in the mind is known prior to its production. Representations are inherently perceptual--constructed by a perceptual process and given meaning by subsequent perception of them. The person perceiving the representation determines what it means. This premise…

Various aspects of iconic memory have been studied in the past. Two tachistoscopic experiments were conducted to examine how legibility of a stimulus affects a subject's ability to recall brief visual presentation. The studies used letter arrays set in four different typefaces (Helvetica, Cooper Black Outline, Electronic, Old English). In the…

Memory studies involving older adults have typically been conducted in laboratory settings and have usually employed experimental tasks. Most results support cognitive decline. Most naturalistic experimental studies relate to spatial memory and test younger respondents. When older respondents are tested, the old sometimes outperform and sometimes…

A study of 21 patients with Alzheimer's Disease and 25 with vascular dementia, the two most common forms of dementia, investigated language impairments in the dementia syndrome to see if analysis of language disturbances is helpful in differential diagnosis. Diagnostic assessment included a neurological examination, detailed medical history,…

The "emic" research method used in cultural anthropology is described and its usefulness in developmental psychology is illustrated. A distinction is made in cultural anthropology between "etic" and "emic" research methods. In etic research observers employ established categories, such as prior definitions of…

When presented with linguistic material, elderly adults are often unable to report as much material as are younger people. To ascertain whether elderly adults are as sensitive as young adults to the underlying structure of the to-be-remembered sentences, a study was conducted using the item recognition priming technique. In this technique, people…

Examined in three studies were the influence of perceptual organization on children's memory and the relationship between operational thought and memory performance. In the first study, 72 children at 5, 7, and 9 years of age were given a series of Piagetian tasks and a memory task. Subjects were presented with 10 color-shape pairs depicted in…

A series of studies was conducted to determine whether children's reasoning is capacity-limited and whether any such capacity, if it exists, is based on the working memory system. An N-term series (transitive inference) was used as the primary task in an interference paradigm. A concurrent short-term memory load was employed as the secondary task.…

To explore the effects of depression and learned helplessness on cognitive task deficits, 66 community-residing elderly adults were categorized as depressed or nondepressed based on Beck Depression Inventory scores. After a pre-test battery measuring short-term memory and components of crystallized/fluid intelligence, the subjects responded to a…

Research has suggested that memory performance may be related to the extent of stimulus processing during acquisition. To examine processing efficiency and processing deficiency differences between younger and older adults, four studies were conducted. In the first study, young and old adults rated word lists, manipulated for generation specific…

Progress is now being made toward ascertaining the specific effects of rearing conditions on brain and behavior, the properties of the environment that contribute to these effects, and the developmental periods in which brain tissue is most sensitive to environmental modification. (Author/RH)

Two experiments were conducted using the procedure reported by Wickens in 1972 for the study of relevant encoding dimensions in short-term memory. (Editor)

The present experiment was an attempt to determine whether, under different testing procedures and with different stimulus materials, an effect of poststimulus study time on picture recognition could be demonstrated. (Author)

Two memory theories predict that it should be possible to produce negative recency in initial recall. The first experiment provides a demonstration of that predicted negative recency effect. (Editor)
