Because of the increasing use of color in instructional materials at the level of the primary grades, the Health Service Department of the Denver Public Schools became interested in investigating the color vision of 5- and 6-year-olds. A project was established to create color-vision testing methods and to use those methods to ascertain incidence…

Talks presented by Doris Johnson and Regina Cicci at an institute for teachers of the educationally handicapped are summarized and include identification and remediation of auditory receptive language disorders, disorders of spelling and written language, an analysis of reading methods, an analysis check list, disorders of quantitative thinking,…

Vision is a complex process involving three phases: physical (acuity), physiological (integrative), and psychological (perceptual). Although these phases cannot be considered discrete, they provide the basis for the visual screening procedure used by the Reading Services of Colorado State University and described in this document. Ten tests are…

Project SEE was designed as a structured kindergarten and first grade program for the development of visual perception. Short daily lessons were given to an entire kindergarten class simultaneously and were centered around a set of 40 cards containing various lines and shapes. Children were asked to analyze and describe these elements on the…

This study presents results from an experiment designed to assess whether the employment of teaching approaches consistent with the auditory or visual perceptual strengths of disadvantaged boys would facilitate their ability to learn and retain a list of unknown words. Two groups of 20 pupils were identified from a sample of 105 subjects. One…

This study attempted to investigate the effects of school experience on visual perception tests involving line figures and forms. There were two experiments in this study. Experiment 1 examined the independent and interactive influences of school experience and chronological age in kindergarten children. Experiment 2 compared the effects of…

The relationshp between success in learning to read and success in drawing tasks that used the same varieties of perception needed in learning to read was investigated. Ten tasks involving perceiving presented forms, memorizing them, and reproducing them in drawing were given to 150 children. These tasks were related to position in space,…

A test of aircraft recognition accuracy and decision speed compared the performance of single observers and four-man crews. The test used miniaturized simulations of aircraft which were moved at scaled speeds, altitudes, and distances. The validity of the simulation was evaluated and judged by comparing the results of the test with results…

Photographs of visual phenomena are presented to stimulate an awareness of the visual transition between the initial discovery of sights and their utilization in creative works. The visual phenomena are grouped into four units: changes on the surface of objects, perceptions of form, variations in perceptions due to the organization or association…

Three short studies were conducted on long-term effects of visual perception training on perceptual memory, involving the visual illusion of apparent movement, in educable and trainable mentally retarded children (EMR and TMR) and in learning disabled children (LD). Variables were lengths of training session and retention interval. Tables…

Human recognition behavior is influenced by the phenomenon of shape constancy, which occurs when the shape of an object is correctly perceived regardless of the orientation of the object in space. The research reported here tests the validity of the shape-slant invariance hypothesis, a theoretical formulation of the phenomenon of shape constancy.…

The two experiments reported are part of a series evaluating effects of display parameters, task variables, and operator perceptual limitations on ability of Night Vision Device operators to process visual information quickly and accurately. For untrained observers, target brightness requirements were higher for identification than for detection,…

This 115-page annotated bibliography contains material on perceptual motor development. The introductory portion of the bibliography presents general reading on perception, learning, and development. The first portion contains annotated works by six specific authors. The second portion presents works grouped under the following headings: a)…

Reported were estimates of the uncorrected binocular visual acuity levels of distance and near for children aged 6 to 11 years in the noninstitutional population of the United States in relation to their demographic and socioeconomic background. A sample of 7,119 children participated in the Health Examination Survey program of 1963-65. Findings…

The differential visual responses of 20 Down's Syndrome and 20 normal infants (CA 8 months) to 13 pairs of visual targets were compared. Although DS subjects generally looked longer at the stimuli than normal subjects, they showed a response differential in only 3 stimulus pairs compared to 11 for the normals. Six of the stimulus pairs elicited…
