A vocabulary list of 50 words based on children's spoken language was divided into six groups. For each group specific materials incorporating different modality presentations (pictures, tapes, transparencies, and word cards providing tactile emphasis) were developed. The modality preferences of 128 first graders were identified by The New York…

This document reports on a study of how the eye and the hand become functionally coordinated during growth. A specific question researched is "How do children use their hands as perceptual tools for exploring objects in order to acquire information about them?" It was assumed that a pre-school child would have evolved a form of eye-hand…

The purpose of this study was to investigate the effects of perceptual focus and planar orientation of rods on conservation responses when parallel translations are utilized. The translations along the major axes of symmetry utilized two modes: (1) translation of one of two rods, and (2) simultaneous translation of two of three rods in opposite…

The investigation was undertaken to obtain data on the number of kindergarten, second, and seventh grade Ss classified as having color vision defects by the American Optical-Hardy, Rand, Rittler Test (AO-HRR) and two tests by S. Ishihara. Also studied was the ability of color vision defective and color normal Ss to utilize color as measured by the…

The experiment described in this report investigates the effects of various cognitive cues in questions asked regarding the relationship of elements in pictorial depth perception. The subjects of this study are 40 third grade Black and Puerto Rican children. They are confronted with four pictures from the Hudson Depth Perception Tests and asked to…

A detailed program for the development of pre-reading visual perceptual skills in young children is presented which provides benefits to both teacher and child due to its scope and flexibility. The program is primarily visual-motor, providing at the same time experiences in language and concept development. The prescribed sequence of lessons…

Two experiments evaluated the effects of mnemonic training upon 5- and 10-year-old children's learning and retention of patterns at varying intervals. Subjects were 172 middle class children evenly distributed across the two age groups. Experiment I investigated the effects of individual strategies (perceptual exploration, organization of…

Provides background theory and an experiment relating to chemometrics. Describes the phenomenon where solutions are dichromatic or dichromic. Discusses the difficulty students have in describing such solutions that appear to be several different colors at the same time. (TW)

Reports on a study that investigated the span of letter recognition (the region of text from which letter information is used during a fixation) for good and poor fifth-grade readers during a reading task. (HOD)

This paper presents a summary of the research literature concerning the psychological and behavioral impact of sexual abuse of children and adolescents. It examines the dynamics involved in the process of making such determinations and examines the utility of using Human Figure Drawings as part of an assessment battery to determine the probability…

Because the Matching Familiar Figures Test has a heavy visual perceptual loading, its usefulness for measuring cognitive style was examined with cerebral palsied students, frequently characterized by ocular anomalies and visual perceptual deficits. The students' cognitive styles were qualitatively similar to nonhandicapped. Extraocular movements…

Evaluation of 54 mentally retarded pupils, aged 10 to 13, in 1979 and comparison with six samples of mentally normal pupils collected during the last two decades confirm that prevalence of additional problems among mentally retarded pupils is greater as compared to mentally normal pupils with respect to nine variables. (NEC)

To heighten teachers' observational awareness, outlines the behavioral characteristics that are symptomatic of learning disabled adolescents and suggests for each category of general, visual, and auditory symptoms, classroom methods for circumventing learning problems. (AYC)

Discusses the size-weight illusion that occurs when a person lifts two equal-weight objects differing in size and perceives the larger object as lighter than the small object. Describes several inexpensive techniques for demonstrating the size-weight illusion and reviews some relevant issues concerning this phenomena. (MJP)
