Factor structure of intellectual, visual perception, and visuomotor performance of poorly co-ordinated boys.
A battery of intellectual, visual perception, and visuomotor tests yielding 15 subtest scores were factor analyzed to determine the factorial structure of these tests in poorly coordinated boys. 5 rotated orthogonal factors were identified accounting for 76% of the variance in the battery. 3 of the factors were primarily intellectual, including one performance factor and 2 general intellectual factors. The remaining 2 factors were primarily visual, with one being most clearly represented by the Bender-Gestalt and interpreted as a form reproduction factor. The other factor was less clearly interpretable involving both eye-hand coordination and discrimination of position in space.
