Learning disabled subjects functioned on both the cognitive and perceptual sections of a Time Understanding Inventory at a level three grades below their CA grade placement equivalent, suggesting that their lack of mastery of time concepts represented a generalized rather than specific disability.

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)

The results suggested that on a perceptual task not related to reading or mathematics, the addition of input from tactile and auditory sensory modalities does not improve learning performance and, in certain combinations, actually interferes with such performance. (Author/SBH)

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)

The role of mental age (MA) and visual-perceptual ability in number concept development was examined with 48 nonretarded and retarded children from regular school settings. (Author)

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.

A sample of 247 Educationally Handicapped (EH) children at ages 6-10 was investigated to determine the role of static balance impairment in learning disabilities and the possibility of improving reading through balance training. Significant correlations between balance ability and reading level were found in only about 40% of the sample,…

Fifty-two educable mentally retarded children (8-14 years old) were randomly assigned to either a visual-spatial training condition or a control group. (Author)

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)
