Using 60 subjects, aged five to eight, this study assessed the magnitude of relation between deaf children's perceptual motor development, measured by the Developmental Test of Visual Perception, and their language development. The relationship was positive and significant, but the value too small to indicate reliable association for individuals.…

This brief overview on dyslexia notes the problems of defining this syndrome, presents a profile of a "typical" dyslexic child, and describes the three sub-types of dyslexia which have been identified. (SJL)

Shows how to use Rudolf Arnheim's theory of visual thinking in technical writing classes. (RL)

Investigates the responsiveness of 14- and 20-week-old infants to binocular information using a stereoscopic shadow caster showing an object approaching on a collision course. (Author/SS)

Investigates the magnitude of the over- and under-estimated portions of the Ebbinghaus (Titchner's circles) illusion in 688 subjects ranging in age from 5 to 70 years. (Author/SS)

Explores sensory experiences, both real and imagined, that occur while reading. (MKM)

Three experiments investigated four-month-old infants' capacity to perceive bimodally specified events by detecting the temporal synchrony of sound bursts with the visable impacts of surfaces. (Author/SS)

The effectiveness of motion parallax for relative and absolute distance judgments was studied using second-, fourth-, and sixth-grade children and college students. (JMB)

Tested whether a verbal description given before or after presentation of a picture effected visual processing and/or memory. (SB)

Schoolboys from the Ivory Coast and from Kenya were tested on a simple task intended to detect the effect of implicit-shape constancy. (Editor)

In answer to R. Allington's criticism of the Jordan Left-Right Reversal Test (JLRRT), the author contends that Allington's research used an outdated version of the JLRRT, that Allington's research into the relationship of visual reversals to reading skills does not reflect on the validity of the test to measure reversals.

Separation thresholds for groups of 26 dyslexic and normal children attending the first year of secondary school were obtained with pairs of identically-oriented and spatially-overlapping straight lines presented at orientations varying from zero to 90 degrees. (Editor)

It is much easier to look for an unfamiliar character (such as an upside down A) embedded among familiar ones than to look for a familiar character (A) among unfamiliar ones. Furthermore, the nature of the background seems more important toperformance than the nature of the target. (Editor)
