Information is presented on the validity, reliability, and normative data of the Ashlock Tests of Visual Perception-Revised, a screening test for perceptual difficulties in preschoolers. Discussed are implications for using the test for screening, diagnosis, and educational planning. (CL)

The paper examines issues concerned with the incidence of visual perceptual learning disabilities among deaf and partially hearing children. Evidence indicating a high incidence (15.5 percent of 682 deaf students) of visual perceptual deficits is offered, as is a definition of visual perception. The impact of visual perceptual deficits on…

Visual and auditory paired-associate learning tasks were presented to 125 fourth grade children (45 learning disabled, 39 border line learning disabled, and 41 nonlearning disabled). The visual task produced a greater number of correct responses than did the auditory task. There were no differences among groups on either task. Scores on the…

Wechsler Intelligence Scale for Children-Revised (WISC-R) subtest scatter and Bannatyne recategorization scores were investigated with three types of learning disabilities in children 6 to 16 years old: visual-motor and visual-perceptual disability (N=66); auditory-perceptual and receptive language deficit (N=18); and memory deficit (N=12). Three…

In an effort to examine the pragmatic effects of definitions of learning disabilities and identification procedures, information was gathered on the characteristics of 53 children (grades 1 through 7) who had been previously diagnosed as learning disabled. Results of tests such as the Wechsler Intelligence Scale for Children and the Illinois Test…

The author discusses the role of perceptual training in the education of young perceptually handicapped children. Distinctions are drawn between perception and awareness, and the necessity of stimulation to encourage infant and child learning is emphasized. Commonalities between perception and learning are underscored. The author stresses that…

Described is the Kirshner Saroj Visual Perception Speed Test (KSVPST), a measure of perceptual speed using pictures to identify children whose reading difficulties are due to visual processing deficiencies. It is explained that 323 children 6-13 years old were given the Keystone Visual Skills Test, the KSVPST, and reading readiness tests. Data are…

A study compared peripheral vision applied to letter-pair and Dolch word recognition. Subjects, 6 normal readers, 12 Chapter 1 students, and 34 learning disabled (and assumed dyslexic) students from grades one through three enrolled in a parochial school, a public school, and a university summer reading clinic, completed a test designed to…

The basis of perception is found in the sensory experiences of an individual. Cognition, in turn, may be thought of as organized perceptions. Hence, diagnosis of learning disabilities should start with an assessment of the sensory skills in order to gain insight into the probable perceptual and cognitive problems involved in learning. The taxonomy…

The author reviews attempts to categorize reading disabilities, describes a means of refining testing procedures to classify three diagnostic patterns of reading disorder, and reports results of application of those procedures with 172 children with reading disorders. Studies classifying poor readers by a verbal-performance pattern analysis of the…

Frequently a variety of visual perception difficulties correlate with reading disabilities. A study was made to investigate the relationship between visual perception and reading disability in families, and to explore the genetic aspects of the relationship. One-hundred twenty-five reading-disabled students, ages 7.5 to 12 years, were matched with…

Visual difficulties among students with learning disabilities take two forms: visual-processing dysfunction and deficits in basic visual skills. Students with a visual-processing dysfunction have problems interpreting visual information even when the visual information is clear. Students with basic visual disability have problems obtaining…

A study was conducted of 70 abused males (ages 6-16) with emotional disturbances living in 6 residential facilities, to investigate the incidence of learning disabilities. Each participant received a battery of psychological, neuropsychological, personality, behavioral, and achievement tests. Results found: (1) the standard scores on all…

This study investigated the construct validity of five perceptual traits (auditory discrimination, visual discrimination, visual memory, visual-motor coordination, and auditory to visual-motor coordination) with five simulated work samples (union assembly, resistor reading, budgette assembly, lock assembly, and nail and screw sort) from the Jewish…

Two experiments were conducted to assess the performance of freshmen chemistry students with poor spatial visualization skills. In the first experiment, 31 chemistry students with academically deficient backgrounds completed a diagnostic test of their ability to visualize and interpret pictorial representations of simple molecular structures. At…
