Twenty-four children (8 to 9 years old) who reversed letters were randomly assigned to either the control or experimental group (15 additional minutes of laterality training per day for 4 weeks). Analysis of results demonstrated that training did not significantly affect the number of reversals. (Author/CL)

Aesthetic preferences for overlapping geometrical figures were studied in subjects ages 6 through 14 in the context of the theory of functional pleasure. Results confirmed the hypothesis that the complexity level (number of crossings) of the preferred stimulus varies with the subjects' perceptual capacities, which develop with age. (Author/SJL)

To examine the relationship between performance on the Frostig Developmental Test of Visual Perception and birth order, 578 first-graders were tested. (Author)

Reports a study comparing two auditory-visual integration tests, one basically that developed by Birch and the other using Morse-type stimuli. Suggests reasons why the Morse form of test was more highly correlated with reading ability than the Birch test. (TO)

Apparent ambiguities in Levy and Reid's writing posture criteria and dissimilar criteria used by other investigators are discussed. This review suggests that an adequate test of hypothesized relations among handedness, hand posture during writing, sex, and cerebral organization requires development of a standard set of valid criteria for writing…

Ss displaying initial subnormal nystagmic functioning responded to therapy with increases in duration, while other Ss displayed decreases; these effects were more apparent after long therapy. (Author/DLS)

Among the many theories attempting to explain sex differences in spatial ability, one of the most highly researched is the X-linked recessive gene theory. This is a review of the major research done on that theory and shows the conflicting nature of the results. (Author)
