This guide for parents of children with dyslexia begins with case summaries of several children who exhibited reading and other academic problems that were later diagnosed as dyslexia. Misconceptions about dyslexia are refuted, and developmental problems in the areas of auditory perception, visual perception, and language processing are discussed.…

The study determined if a significant difference was demonstrated between American Indians and Caucasians on visual perception and recall tasks associated with cognitive function. It was hypothesized that a significant difference existed between scores obtained by Indian children enrolled in reservation schools and that of Caucasian children…

RESEARCH STUDIES RELEVANT TO SOME ASPECT OF VISUAL IMPAIRMENT ARE CONTAINED IN THE BULLETIN. D.M. BAUMANN AND OTHERS REPORT ON THE COLLAPSIBLE CAN, AND T.L. DEFAZIO AND T.B. SHERIDAN ANALYZE THE VIBRATIONS OF THE CANE. J.J. GIBSON CONSIDERS SENSITIVITY, AND J. MICKUNAS, JR., AND T.B. SHERIDAN DISCUSS THE OBSTACLE COURSE IN MOBILITY EVALUATION OF…

Designed for parents and teachers, the manual contains suggestions for approximately 70 inexpensively constructed games, activities, and manipulative materials for use with handicapped and non handicapped young children. Suggested are procedures for conducting materials workshops for parents and teachers. Instructions are provided for items…

Analyzes the research strategies, stimuli, subjects, statistical strategies, and relative variables in 34 empirical studies on children's representation of three-dimensional objects. The studies fell into three categories: children's representation of spatial relationships within an object, between two objects, and studies that included both. (MJP)

The goal of this review of the clinical and research literature is to identify, describe, and critique published methods for assessment of attention and related functions in preschool children (ages 6 and younger). The need for valid assessment of preschool children has grown dramatically in the past two decades following the implementation of…

This report summarizes the work conducted for the Artificial Intelligence Measurement System (AIMS) Project which was undertaken as an exploration of methodology to consider how the effects of artificial intelligence systems could be compared to human performance. The research covered four areas of inquiry: (1) natural language processing and…

This contradicts N. F. Johnson's arguments that word perception does not follow letter perception and that letter analysis awaits identification of the word as a unit. His experiments lack controls, and uncontrolled factors may contribute to his effects. Johnson's implications for prior-letter-processing models are contradicted. (CHK)

Tested two hypotheses to account for results of an earlier study in which preschoolers failed to display differential behavior when instructed to memorize itmes or merely to examine them perceptually. Subjects included second and fifth graders as well as preschoolers. (CW)

The ability of 1-month-old infants to recognize their mothers visually was explored with the live faces of mother and stranger presented in three different poses: en face (full face), half-profile, and profile. Subjects were 16 infants with normal Apgar scores at birth who were volunteered by their parents after an initial contact in a maternity…

According to Piaget, young children have a profoundly different conception of distance than do adults. In fact, Piaget argues that young children do not have a conception of distance since they do not conceive of distance as being composed of fixed units of space. In contrast, results of a series of studies indicate that in tasks requiring…

The technique developed in this research paper for analyzing the information in charts and graphs is designed to reveal design flaws in the display that may prevent them from conveying information effectively. This analytic scheme requires isolating four types of constituents in a display and specifying their structure and interrelations at the…

Understanding vision is not a simple task. Nevertheless, a great deal is known about vision, more than about any of our other senses. The articles collected in this volume were chosen and organized with the intention of providing a survey of a number of different areas of vision research. Three major sections focus on the general categories of…

This paper reviews the aspects of cognitive science that relate best to using electrical and magnetic recording to understand the function of brain systems. It outlines a framework for relating cognitive activities of daily life (typing, reading) to underlying neural systems. The framework uses five levels of analysis: task, elementary operations,…

Young children matching the orientation of (a) identical realistic figures that could form mirror images of each other, or (b) nonidentical realistic figures that could not form mirror images, produced the same pattern of errors. The explanation proposed is a strategy of matching analogous parts of the two figures. (Author/SDH)
