A preliminary investigation of patterns of teacher thought about student reasoning and learning involved presenting 23 preservice teachers with a "dilemma of practice about equity." Resulting stages of teacher development concerning equity in reasoning were found to correlate significantly with Perry's scheme. However for those who hold…

Goals and challenges pertaining to infant sensory and perceptual development are discussed. It is suggested that the inability of researchers to think and talk wisely about "partial accomplishments" in development creates a barrier in developmental research. Conceptual schemes are needed to accommodate these partial accomplishments. Three major…

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…

An experimental test battery designed to measure several perceptual abilities was administered to 1,368 (51.8% male) paying clients of the Johnson O'Connor Research Foundation (JOCRF) in an effort to identify and measure three perceptual abilities: (1) flexibility of closure; (2) speed of closure; and (3) spatial scanning. Subjects, who ranged in…

According to J. Piaget, the child continually constructs or refines previous constructions in defining reality. Taking Piaget's lead, a study attempted to describe how children construct reality, with particular emphasis on the role of television in that construction. Four young children were observed and audio taped in viewing situations in their…

Competence in action perception seems to be achieved very early in life. Because research has indicated that competent perceivers of action must be able to discriminate breakpoints in behavior, then recognition memory for breakpoints should be superior to that for nonbreakpoints at all ages where competence in action perception exists. Two studies…

One hundred and sixty first grade boys and girls of normal intelligence were tested for ability to conserve multiple space relations. The criterion task apparatus was a wooden T with a model of schoolhouse attached and centered above the point of contact of the horizontal and vertical axis. The T had a track running the length of both its axes…

The linguistic relativity hypothesis is the view that the language a person speaks influences his perception of the world. This hypothesis is frequently misunderstood to be a question of the influence of language on culture, when in reality it emphasizes the influence of language on the cognition of its speakers. This distinction between culture…

This paper analytically reviews the literature on cognitive development, particularly as it relates to the acquisition of language. Of primary concern are the basic cognitive processes of perceptual groupings, concepts and relations, and memory. Discussed are the acquisition of language, some aspects of the nature of language and language…

The author reviews findings in perception, cognition, psycholinguistics, and motivation, concentrating on the development of these processes in the nonreading and beginning reading child rather than in the mature processes of a skilled reader. She offers the following conclusions: (1) Research in perception suggests that there are developmental…

Investigates the relationships between levels of cognitive complexity and three levels (graphic, formal, and inferred) of modeling complexity in community college students. (GA)

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 ability of nine-month-old infants to imitate simple actions with novel objects. Looks at both immediate and deferred imitation. Findings show that imitation in early infancy can span wide enough delays to be of potential service in social development. (Author/RWB)

Reviews the research literature on the abilities of infants to categorize visual information on dot patterns; schematic faces; hue; and orientation. (HOD)
