When a visual search task is very difficult (as when a small feature difference defines the target), even detection of a unique element may be substantially slowed by increases in display set size. This has been attributed to the influence of attentional capacity limits. We examined the influence of attentional capacity limits on three kinds of…

Perception of objects in ordinary scenes requires interpolation processes connecting visible areas across spatial gaps. Most research has focused on 2-D displays, and models have been based on 2-D, orientation-sensitive units. The authors present a view of interpolation processes as intrinsically 3-D and producing representations of contours and…

Controlled Drawing Observation (CDO) was developed by Tove Krogh and it has been used in Denmark, Finland and Estonia for assessing a child's readiness for school. CDO is a group test, it gives information about a child's functioning in an educational setting and it serves as a starting point for later individual assessment. The goal of the study…

Fifty-four kindergarten children were screened with the Sapir Developmental Scale to highlight deficiencies in bodily schema, perceptual motor skills, and language development, and were matched in groups of three by score, chronological age, and sex with one of the three acting as control. Three first grade classes were organized as follows: one…

This guide is intended to help the literacy practitioner in the identification of adults with learning disabilities. These adults have worked diligently for a year or more to improve comprehension skills, writing and spelling, or work skills, yet, have made little progress. The role of screening as only the first step in a process involving a…

This report presents the results of a study designed to evaluate the Johnson O'Connor Research Foundation's (JOCRF's) measurement of structural visualization. Three experimental tests--the Incomplete Open Cubes Test, the Guilford-Zimmerman Spatial Visualization Test, and Raven's Advanced Progressive Matrices--were added to the JOCRF's test battery…

A study consisting of two experiments attempted to further adapt the visual preference procedure for determining children's meaningful phonological perception. In the first experiment, 1-year-olds were presented with auditory stimuli (words) and screens containing paired color photographs of the object described by each word and of an unusual…

When handled well, description can give poetry and prose a quality of immediacy and accessibility by creating a dramatic context in which the writer's ideas and feelings can be shared by the reader. The use of perception stimulation can aid the student in producing effective images that lead to this dramatic context. To begin this learning…

The HPI Texas Preschool Screening Inventory (TPSI) is a test to help determine which children might be a risk for learning problems as they enter kindergarten or first grade. The HPI Manual describes the procedure, score interpretation, and rationale for seven components of the test, including auditory memory for numbers and letters, visual memory…

Twenty-six test variables for psychological differentiation and cognitive abilities were factor analyzed with a view towards replication of certain factors of perceptual and conceptual differentiation and related these factors to cognitive abilities. (Author)

Although numerous studies have indicated that older persons process visual information more slowly than younger persons, the precise nature of age-associated changes in the processing of visually presented information remains unclear. Older adults (N=18) and college students (N=18) performed a visual search task in which lists of words and…

THE RELATIONSHIPS BETWEEN AUDITORY AND VISUAL FUNCTIONING AND READING ACHIEVEMENT WERE EXPLORED. AN ADDITIONAL OBJECTIVE WAS TO INVESTIGATE THE INFLUENCE OF DEVELOPMENTAL FACTORS ON THESE VARIABLES. A WIDE RANGE OF AUDITORY AND VISUAL SKILLS WAS SAMPLED IN POOR AND NORMAL READERS AT THREE DIFFERENT GRADE LEVELS (FIRST, THIRD, AND FIFTH). DATA…

A previous study by Gibson et al. (1972) that investigated the effect of orthographic structure on letter search was replicated and extended in order to identify factors that might explain the apparent discrepancy between their results and those of comparable studies. Experiment one tested whether the discrepancy might be explained by difference…

The booklet describes a functional approach to evaluation of instructional materials which resulted from Project CHILD, a research effort to validate identification, intervention, and teacher education programs for use with language disabled children. Explained is a summer training program for teachers in the evaluation of materials which stressed…

This study is designed to evaluate the musical listening ability that children have acquired through present instructional practices. To obtain an estimate of what children learn, over 3,000 students in grades 4-7 were administered a Melodic Listening Survey (structured into nine subtests) by tape recording under the direction of their own…
