THE ROLE OF VISUAL SENSORY DEFICIENCIES IN THE CAUSATION READING DISABILITY IS DISCUSSED. PREVIOUS AND CURRENT RESEARCH STUDIES DEALING WITH SPECIFIC VISUAL PROBLEMS WHICH HAVE BEEN FOUND TO BE NEGATIVELY RELATED TO SUCCESSFUL READING ACHIEVEMENT ARE LISTED--(1) FARSIGHTEDNESS, (2) ASTIGMATISM, (3) BINOCULAR INCOORDINATIONS, AND (4) FUSIONAL…

The main objective of the present investigations was to determine whether or not young human infants see the physical spectrum in a categorical fashion as human adults and animals who possess color vision regularly do. (Author)

What shade of gray a surface appears is related to the perceived distribution of light and shadow, which in turn depends on the perceived spatial relation between the surface and its neighbors. (Author/ BB)

First, third, and fifth graders made judgments of the geographical slant of surfaces depicted in photographs while optical slant and postural orientation were manipulated. The results indicated the existence of a linear mechanism which compensates for the effect of postural inclination. (JMB)

The span of apprehension (a measure of the amount of information processed simultaneously from a brief visual display) was studied in two experiments involving 40 normal and learning disabled boys (ages 6-11 years). (Author/DLS)

Reports a series of experiments that give evidence for retention of information about color in very short-term visual memory, commonly termed "iconic memory". (Author)

Although perception theory and research are relevant for learning theorists and educational technologists, they have not been regarded as a practical resource by most. Their place in education will be determined by empirical testing of psychological hypotheses as well as by philosophical assumptions. (Author/STS)

In a study involving the reading of bar graphs it was found that students in the control group (who did not receive generalization cues) did significantly better than those in the experimental group. (Ed.)

Sense of direction was studied as a verbal expression of people's estimation of their own spatial orientation ability, rather than as a special mental faculty. Relates sense of direction to cognitive ability and to self concept. (Editor/RK)

Investigations of the relation between judged length and measured length have concentrated on determining the form of the psychophysical function. The process by which the observer arrives at his judgment has not been described. An exploratory experiment was carried out in an attempt to identify the process. (Author)

Results showed that 2- and 3-dimensional forms affected 4- and 8-week-old infant visual behavior differently. (Author/JMB)

Presents an introduction to the study of images of blacks in visual media and considers some of the problems involved in applying visual literacy ideas to the specific area of race and racism. (MH)

A visually directed sensory motor training program with a 30-day duration did not enhance the depth perception of five-year-old children. (MM)

In two experiments, forty 26-week-old infants were repeatedly exposed to an object and were then shown an object that was different from the original object in color, shape and/or texture. Results showed that looking and manipulation increased for the novel shape and texture objects and looking increased for the novel color object. (Author/JMB)
