Prior studies found individual differences in visual recognition memory during infancy were related to individual differences in later intelligence. This paper discusses methodological issues in the measurement of infant visual recognition, the significance of previously obtained predictive validity coefficients, and the theoretical question of…

Presents results of two experiments which measured contrast sensitivity function in infants. Information concerning development of visual acuity, low frequency attenuation, and sensitivity to contrast were collected. Results provide an approximate picture of and means for detection of infants' pattern information. (Author/DB)

The authors discuss methodological and theoretical issues in psychological investigations of infant attention, fixation times, habituation, and intelligence. A consensus on how to measure individual differences in habituation has not been reached. The relation between IQ and attention is discussed. (RD)

The relationship between reading ability and recognition of four kinds of perceptual stimuli for purposes of reading disability diagnosis was investigated. The sample consisted of 84 male grade-3 pupils who were matched on intellectual ability but who differed in reading proficiency. Three groups, based on a 6-month discrepancy either above or…

To investigate the effects of perceptual training upon selected measures of reading achievement in grade 1, 12 experimental classrooms of randomly selected first graders received a 29-day adaptation of the Frostig Program for the Development of Visual Perception. Thirteen control classes added comparable time to the regular reading instructional…

This paper presents evidence that the Snyder/Pope Visual Memory Technique using the Bender-Gestalt Test is a useful predictor of reading ability for first-grade children. Short-term visual recall appears highly related to the Grade 1 reading task and should be assessed when children begin learning to read. (Author/SJL)

The construct and predictive validities of the Perceptual Ability Test (PAT) were examined. The results indicate that each of the subtests exhibits different predictive validity. A linear combination of PAT subtest scores was found to be more predictive of first-year dental school technique performance than the total PAT score. (Author/MLW)

Theoretical implications of individual differences among infants in responsiveness to visual novelty being predictive of later intelligence differences are discussed. Issues discussed include: continuity of intelligence over development, relation of aspects of information processing to intelligence, role of hereditary and environmental influences…

The agreement between visual analysis and the results of the split-middle method of trend estimation was examined using a set of 24 stimulus graphs and 30 raters. Results revealed poor agreement between the two methods, and low sensitivity, specificity, and predictive ability for visual analysis in relation to statistical inferences. (JDD)

THE RELATIONSHIPS BETWEEN PREREADING MEASURES OF VISUAL-MOTOR-PERCEPTUAL SKILLS AND READING ACHIEVEMENT WERE STUDIED. SUBJECTS WERE 172 FIRST GRADERS. PRETESTS AND POST-TESTS FOR WORD RECOGNITION, MOTOR COORDINATION, AND VISUAL PERCEPTION WERE ADMINISTERED. FOURTEEN VARIABLES WERE TESTED. RESULTS INDICATED THAT FORM-COPYING WAS MORE EFFECTIVE THAN…

The development of a research model to aid in the understanding of the hierarchical structure of reading readiness is described. Data were obtained by testing 218 first graders from three elementary schools with the Frostig Developmental Test of Visual Perception, the Gates Reading Readiness Test, the Metropolitan Readiness Test, the Olson Reading…

This paper reviews the studies involving the more commonly measured reading readiness factors, discusses some unique studies, and projects what some needs of future research should be. The research areas discussed include reading readiness tests as predictors of success in beginning reading, auditory discrimination factors and their relation to…

Visual fixations were recorded in newborn, 4-, and 8-week-old human infants as they scanned displays that varied in contour length, size, number, and a new metric, CVAL (based on Contour Variability, Amount and Location). One of the findings was that both contour length and CVAL separately accounted for approximatel1 95 of looking-duration…

This review is one in a series intended to develop methods which maximize the use of the existing scientific literature as a basis for predicting human performance. It is concerned with sensory performance in target detection, defined in terms of the "probability of detection" of a flash of light. Two conditions of detection are…

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…
