The fields of developmental psychology and developmental neuroscience have existed independently of one another for many years. This is unfortunate, as knowledge of how the brain develops can inform the study of behavioral development. In this paper, we provide two examples of how knowledge about brain development has improved our understanding of…

We asked whether the ability to keep in working memory the binding between a visual object and its spatial location changes with development across the life span more than memory for item information. Paired arrays of colored squares were identical or differed in the color of one square, and in the latter case, the changed color was unique on…

Few studies have specifically investigated the cognitive correlates of employment for persons with mental retardation. To evaluate the relationship of cognitive and adaptive functioning to work status, 56 competitively employed and 55 unemployed individuals with mental retardation underwent a comprehensive neuropsychological and adaptive…

Empirical data suggest that there is at most a very small sex difference in general mental ability, but men clearly perform better on visuospatial tasks while women clearly perform better on tests of verbal usage and perceptual speed. In this study, we integrated these overall findings with predictions based on the Verbal-Perceptual-Rotation (VPR)…

In many theories of cognition, researchers propose that working memory and perception operate interactively. For example, in previous studies researchers have suggested that sensory inputs matching the contents of working memory will have an automatic advantage in the competition for processing resources. The authors tested this hypothesis by…

In this study, developmental changes in duration of the icon (visual sensory store) were investigated with three converging tachistoscopic tasks. (1) Stimulus interuption detection (SID), a variation of the two-flash threshold method, was performed by 29 first- and 32 fifth-graders, and 32 undergraduates. Icon duration was estimated by stimulus…

The relationship between visual recognition memory and performance on a paired-associate task for good and poor readers was investigated. Subjects were three groups of 21, 21, and 22 children each, with mean IQ's of 98.2, 108.1, and 118.0, respectively. Three experimental tasks, individually administered to each subject, measured visual…

Presented is a test used to measure visual perception ability, which consists of 30 groups of forms that are similar to lines used in forming letters, but do not make letters. They are comparable to nonsense syllables used to simulate words. Each group includes four forms and is numbered. The test was used in Rodenborn's study to determine the…

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)

This experiment was designed to determine whether children's inability to discriminate mirror-image oblique lines is a function of encoding in memory the left-right orientation or the degree of slope of an oblique line. (Author/SB)

Infants were tested in three studies of the acquisition and long-term retention of category-specific information. Results document retention of category-specific information after intervals of two weeks. (PCB)

Paper calls attention to the extent of iconic information processing in young children and presents data on children's ability to recall iconic information. (Authors)
