The manual was intended to help school personnel (either an educator of the visually handicapped and/or a certified orientation and mobility instructor) evaluate the functional use of residual vision. The manual is organized in three major sections, which cover the following: (1) the general areas addressed in functional vision evaluation (such as…

This fact sheet defines vision, outlines the visual skills needed for school achievement (ocular motility, binocularity, eye-hand coordination skills, and visual form perception), and describes how visual problems are evaluated and treated. The fact sheet also lists clues to look for when a visual problem is suspected, including the appearance of…

The purpose of this study was to determine if the appearance of teachers has an impact on their effectiveness as judged by student ratings and student achievement. Results indicate that there was no difference. (Author/HMV)

This study investigated the extent of infant peripheral vision, specifically the extent of infants' constricted field, or tunnel vision. Thirteen infants, 2 to 5 months old, were tested using a psychophysical procedure to obtain contrast sensitivity thresholds at four retinal loci (-40, -15, +15, +40 deg.). Infants were placed in an infant bed in…

The effects of posture on the visual behavior of 15 3-day-old healthy, black, newborn infants were assessed. Findings suggest that the vestibular, proprioceptive, and contact stimulation provided by the on-shoulder position affects the newborn's ability to follow and process visual stimuli. (Author/CS)

Tests the hypothesis that age-related shifts in infants' visual preferences for stimuli (varying in complexity as defined by number of light-dark intersections) are due to changing attention value both within and between the inversely varying dimensions of size and number. (Author/ED)

This experiment attempted to obtain an estimate of perceptual isolation effects when the isolated item was the only distinctive feature in the list and to obtain data on continuous serial learning in order that isolation and serial-position effects could be compared directly. (Author/RK)

A DOCTORAL DISSERTATION WHICH EXPLORES THE CLASSICAL THEORY OF PERCEPTION IN READING IS REPORTED. THE FACTS REPORTED IN PERCEPTUAL RESEARCH ARE REALIGNED IN TERMS OF CERTAIN PREMISES OF GENERAL OPEN SYSTEMS THEORY AS UTILIZED BY THE SUBSTRATA-FACTOR THEORY AND THE PARTICULAR POINT OF VIEW OF THE INFORMATION THEORIST BROADBENT TO PRODUCE A NEW…

THE IMPORTANCE OF ILLUMINATION TO THE SCHOOL CHILD IS DISCUSSED. VISUAL EFFICIENCY HAS A MARKED EFFECT UPON MANY LEARNING SITUATIONS AND IT IS INFLUENCED BY A NUMBER OF FACTORS--(1) THE STAGE OF GROWTH AND DEVELOPMENT OF THE CHILD'S EYES, (2) THE PRESENCE OF EYE DEFECTS, (3) RELATIVE BRIGHTNESS OF OBJECT AND BACKGROUND (CONTRAST), (4) SIZE OF…

The study undertakes to clarify and redefine some of the concepts underlying the relations between visual perception and thinking. A sample bibliography suggests sources for future research. Psychological and psysiological theory is shown historically to have separated the two mental functions in principle. Correspondingly, present-day education,…
