Sensory integration and single-modality scanning.

An auditory scanning, visual scanning, and auditory-visual integration test was administered to 72 children from grades 1, 2, 3, and 5 to determine whether increases in sensory integration skills could be accounted for by increases in skills of single modalities. Using a multiple regression model, the results indicated that increases in integrative functioning occur independently of developmental changes in individual modalities. Implications for future research are presented.
