Changes in magnitude of Muller-Lyer illusion lines between forks and arrows as a function of age were studied in 48 hyperactive and 48 nonhyperactive boys (six-nine years old).

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)

To determine the intertest reliability of the Beery Developmental Test of Visual Motor Integration (VMI) and the Bender Visual Motor Gestalt Test (BGT), 64 six to nine year olds were administered both tests.

Described is an 8-month program for remediation of learning disabilities in regular classes while receiving supplemental instruction in academics and perception. Significant improvement in arithmetic and perception was obtained, while reading gains were recorded only after 20 months. (Author/KW)

The EEG biofeedback training produced baseline effects in the presumably dysfunctional left hemisphere and had an impact on arousal in task, suggesting remedial potential for the possible hemispheric arousal deficts in learning disabilities. Training the right hemisphere toward higher arousal and the left hemisphere toward lower arousal resulted…

The processing of a transitivity task by 7-, 9-, 11-, and 13-year-old learning disabled children was studied. All Ss, regardless of age, received highest scores on tasks involving linguistic input. There was no evidence of a developmental shift from spatial into linguistic reasoning. (Author/SEW)

Male and female retarded readers (N=80) at two age levels (6.5 to 8.5 years and 10.5 to 12.5 years) did not differ significantly on a number of perceptual, visual-motor, linguistic, and concept formation abilities. (Author)

Investigated was the effect on the sensory integration of 24 aphasic students, of a 7-month sensorimotor program-designed to stimulate the tactile, vestibular, and proprioceptive systems; motor planning ability; bilateral integration; postural and equilibrium responses; visual form and space perception; and motor development.
