Cluster analyses of measures of sensory integration.
Cluster analyses of intercorrelation of scores on tests of sensory integrative, language, auditory, intellectual, and academic tests administered to young learning-disabled school children demonstrated a close relationship between academic achievement, the right ear score on dichotic listening, language expression, and auditory memory. Visual perception tests and the Auditory Association sub-test of the Illinois Test of Psycholinguistic Abilities showed a close association with IQ. Others associations were consistent with the view that when the two cerebral hemispheres do not corroborate, both hemispheres tend to develop similar motor and language functions. Analyses of the intercorrelation of scores on the sensory integration, auditory, and language tests resulted in four major factors: auditory-language functions, postural-ocular reactions, eye-hand coordination, and somatosensory and motor planning or praxis. A fifth factor, visual perception, contributed less to the final factor structure.
