Flax, Nathan – Amer J Optom & Arch Amer Acad Optom, 1968
Using published research data, the problem of the seriously retarded reader was examined to determine the role of vision. The most obvious visual factors such as acuity and refractive error did not seem related to the problem. Impairment of visual skills such as fusion and accommodation did seem to contribute to reading difficulty, but such…

PDF pending restorationCarvell, Robert L. – 1975
The purpose of this study was to compare mature readers' comprehension of text presented in traditional orthography with their comprehension of text presented in a regularized orthography, specifically, to determine whether, when traditional orthography is regularized, any loss of meaning is attributable to the loss of the visual dissimilarity of…

Investigators in this study looked for conditions that can rapidly establish continuous stimulus control of continuous response variations, or "response mapping." Unlike previous research in stimulus control, where a single stimulus comes to control a single response, 36 5-year-old children received errorless discrimination training at…

Edmonds, Ed M. – 1969
The purpose of the two experiments was to assess the effects of two levels of stimulus redundancy and three levels of irrelevant visual stimulation on performance in a successive discrimination task and a reproduction task. The results indicate that increases in redundancy facilitated performance in the reproduction task but had no appreciable…

Lampe, John M. – 1968
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…

Williams, Robert T. – 1974
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…

Golinkoff, Roberta Michnick – 1974
The purpose of this experiment was to present redundant auditory information along with written displays to see if first graders would be aided in discrimination between legal and illegal nonwords. Seventy-two middle-class first and second graders of both sexes were given one of three treatments to study the effect of redundant auditory…

Borg, Gunnar; And Others – 1971
An experiment was carried out on perceived difficulty of a simple attention task. Seven complex stimulus matrices were used, consisting of different numbers of pairs of consonants. The subjects' task was to search for targets determined by the experimenter one by one. Search time was measured as performance criterion. Perceived difficulty of the…

Severson, Herbert H.; Farley, Frank H. – 1971
This study investigates the hypotheses set forth by Russian researchers that there may be identified a pervasive characteristic of the central nervous system labeled as "strength". Ten of the 12 measures used were direct replications of representative strength measures derived from the Russian work. Two additional measures were included to test…

Frederickson, Edward W. – 1970
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.…

Lewin, Earl P. – 1972
A study investigated changes in recognition time for short sentences presented on television screens of varying sizes with viewers at varying distances. In a posttest only control group design, subjects in several different groups viewed a series of similar sentences under conditions where screen size and distance from the screen were varied. The…

Leeds, Bette G. – 1976
The purpose of this investigation was to study the effect of controlling the letters used in words both for a training program designed to improve visual discrimination and for a word recognition task. The experiment was designed to investigate the influence of simultaneous and successive discrimination learning with stimuli which varied in…

Peer reviewedStanovich, Keith E.; West, Richard F. – Child Development, 1978
Groups of eight- and ten-year-olds and adults visually searched for the presence of a target letter or number in fields of items that were either of the same or a different category (letter or number) than the target. (JMB)

Aeschleman, Stanley R.; Tawney, James W. – Educational Technology, 1978
Application of telecommunications technology to educate children whose physical state or geographic location made attendance in public schools virtually impossible. The Kentucky Project utilized a minicomputer to deliver instruction to severely developmentally retarded children from birth to age six living with their families in sparsely populated…
