Visual recognition, navigation, tracking, and imagery are posited to involve some of the same types of representations and processes. The first part of this paper develops a theory of some of the shared types of representations and processing modules. The theory is developed in light of neurophysiological and neuroanatomical data from non-human…

Three of the modules deal with applications of calculus to other mathematics. These are: 240-Pi is Irrational; 241-The Wallis Approximation of Pi; and 242-Buffon's Needle Experiment. The first of these units focuses on a proof of the irrational nature of pi, and provides exercises and answers. The second module of this group reviews the history of…

In this research report, the influences of handedness, hand position while writing, and familial sinistrality (presence of left-handed relatives) on children's intellectual, reading, and visual-motor performance were investigated. Forty left- and right-handed children between the ages of 7 and 10 served as subjects. To assess hand positions, an…

This study was designed to determine the relationship between the Lowenfeldian visual-haptic (perceptual) and the Piagetian concrete-formal (operational reasoning) continua. The study also investigated the relationship between age, sex, academic goal, academic preference, and a person's perceptual aptitude or intellectual reasoning abilities.…

The Webster diacritical system provides a discrete symbol for each sound and designates the appropriate syllable to be stressed in any polysyllabic word; the symbol system presents cues for correct production, auditory discriminiation, and visual recognition of new words in print and as visual speech gestures. The Webster's Diacritical CAI Program…

READING DISABILITIES ARE DIVIDED INTO THREE CATEGORIES--THOSE CAUSED BY PERCEPTUAL FACTORS, THOSE CAUSED BY PSYCHOSOCIAL FACTORS, AND THOSE CAUSED BY PSYCHOEDUCATIONAL FACTORS. POOR DEVELOPMENT OF VISUAL PERCEPTION CONSTITUTES A DISPROPORTIONATE PERCENTAGE OF LEARNING DISABILITY AMONG NEGROES AND PUERTO RICANS IN CENTRAL CITIES. EARLY CHILDHOOD…

THIS STUDY REPORTS THE FIRST PHASE OF A 5-YEAR LONGITUDINAL INVESTIGATION OF THE COMPARATIVE EFFECTIVENESS OF A HIGHLY STRUCTURED PRESCHOOL PROGRAM AND A TRADITIONAL NURSERY SCHOOL PROGRAM IN AMELIORATING THE LEARNING DEFECTS OF CULTURALLY DISADVANTAGED CHILDREN. THE HIGHLY STRUCTURED PROGRAM IS INTENDED TO OVERCOME PARTICULAR WEAKNESSES OF…

UNDER THE DIRECTION OF PROFESSOR BRUNER, THE CENTER FOR COGNITIVE STUDIES AT HARVARD UNIVERSITY HAS CARRIED OUT A SERIES OF STUDIES ON THE DEVELOPMENT OF COGNITION. THERE HAVE BEEN OVER 30 EXPERIMENTS ON THE GROWTH OF PERCEPTION, PROBLEM-SOLVING, AND REASONING BETWEEN THE AGES OF 3 AND 10, IN PURSUIT OF A THEORY TO ACCOUNT FOR THE CHANGES IN…

Ten prominent cognitive styles are discussed in a literature review. The review of each style includes an overview of the research literature; a review and evaluation of assessment instruments; and identification of styles which seem most relevant for application to Air Force Technical training. The cognitive styles covered are: (1)…

Performance of forward observer students from the Army Field Artillery School at Fort Sill, Oklahoma was investigated in relation to several learner variables. Learner variables were field dependent/independent cognitive style, visual/haptic perceptual style, trait anxiety, scores on the Lorge-Thorndike Intelligence Tests, and achievement scores…

SIX PAPERS OF T.D. CUTSFORTH WERE CHOSEN FOR POSTHUMOUS REPUBLICATION ON THE CRITERION OF RELEVANCE TO CURRENT RESEARCH. THE ARTICLES INCLUDE "THE SYNAESTHESIA OF A BLIND SUBJECT WITH COMPARATIVE DATA FROM AN ASYNAESTHETIC BLIND SUBJECT--CHAPTERS 5 THROUGH 7" (COAUTHORED WITH R.H. WHEELER), "ROLE OF EMOTION IN AN SYNAESTHETIC SUBJECT--SUMMARY AND…

THIS PAPER DOCUMENTS THE GENERAL CONDITIONS OF DISADVANTAGED AMERICANS AND EXAMINES THE PSYCHOEDUCATIONAL PROBLEMS WHICH GROW OUT OF THEM. SPECIFIC STATISTICS ARE REPORTED WHICH DESCRIBE INADEQUATE MEDICAL SERVICES FOR NEGROES, POOR HEALTH, POVERTY LEVEL INCOMES, AND EDUCATIONAL RETARDATION. THE PSYCHOEDUCATIONAL FACTORS DISCUSSED INCLUDE VISUAL…

To describe and compare the psychosensory functioning of normal children and children with specific learning disabilities, 62 learning disabled and 68 normal children were studied. Each child was given a battery of thirteen subtests on an automated psychosensory system representing various combinations of auditory and visual intra- and…

A case history of a 16-year-old Puerto Rican male high school dropout is presented to illustrate the visual-perception difficulties resulting in illiteracy and academic failure. The boy had had a number of years of formal schooling without learning any of the basic skills. Neither the academic nor the work training programs at Mobilization for…

Two experiments studied the influence of an individual's cognitive style on concept identification. Subjects were high school males, classified into levels of cognitive style according to their performance on the Hidden Figures Test. For the first experiment, three non-overlapping groups of 30 each were required to classify figural patterns, which…
