Investigates whether elementary school children can successfully execute a mental rotation on Marmor's state-comparison task without knowledge of logical sequence relations, whereas such knowledge is required to construct or evaluate external representations of the successive states in a rotation movement. (HOD)

Perceptual counterparts of a series of conservation of length tests were presented to subjects who were categorized as conservers or nonconservers conservation of length pre-tests, and to conservers and nonconservers given conservation length training. Perceptual performance of the untrained nonconservers was significantly worse than that of the…

One hundred and sixty subjects ages 7, 9, 11 and 21 years judged the standard Brentano form and a dot form of the illusion of 5 trials at 30 second intervals. (LLK)

The development of elementary school children's graphic representations of the large-scale environment in the context of the development of spatial cognition, especially Piagetian theory, is examined. The nature of children's graphic representations of space is reviewed and examined relative to development of their spatial cognition. (BT)

The hypothesis that overall-similarity relations structure both adults' and children's classifications of heterogeneous objects (objects that differ in a variety of ways) was supported in two experiments. When objects varied simultaneously on many dimensions, adults and children constructed classifications that maximized within-category similarity…

In a task designed to separate perceptual processes from memory, reading-disabled 12-year-olds showed no perceptual deficits as compared to their peers. However, they exhibited major deficiencies in memory skills, appearing to suffer from a basic information-processing deficiency. (Author/CS)

This report summarizes four groups of experiments examining the nature of basic perceptual processes in reading. The first group examined the relationship of English orthography to reading, specifically the transfer of information from the icon to short-term memory. The second group of experiments examined the use of peripheral information…

A mathematics curriculum for moderately and severely retarded and autistic students and adults should possess 10 necessary characteristics, including provision for instruction based on assessment results, stress on functional application, focus on generalization of skills, and specific criteria for mastery of each skill. The functional but…

The study examined the hemispheric laterality of 39 deaf children in the upper primary and intermediate grades. (Author)

Examines spatial concepts required by young children for the understanding and manipulation of turn commands in Logo, and reviews the literature on children's Logo learning and the psychological-cognitive development of spatial concepts. Geometric concepts, alternative frames of reference, and the use of Turtle graphics are also discussed. (39…

Investigates the effects of predisposed and distinctiveness-based salience on children's classifications in 96 preschoolers and fifth graders given a classification task designed to reflect a developmental shift from integral to separable perception. (Author/MP)

Six experiments involving 262 children (as young as 16 months and as old as fifth grade) indicate that the basic framework for coding location is present early in life and that later development consists of an increasing ability to impose organization on a broad range of bounded spaces. (SLD)

All contemporary learning theorists agree on the advantages of involving students in authentic problem-solving activities in both in-school and out-of-school contexts. Approaches which use real-world problems as learning tools fit well with: (1) the strategy-based, performance model advanced by information processors; (2) the impasse or…

The purpose of this study was to investigate the development of organizational processes for both verbal and spatial stimulus materials within an information processing framework. Children in grades 2 and 4 and adults were tested for their ability to report letter strings reflecting various orders of approximation to English and various dot…

Describes two experiments that examined the effects of quantity and depth of processing on elementary school children's time perception. (HOD)
