Visually impaired children and haptic intelligence test scores: intelligence test for visually impaired children (ITVIC).
This paper reports the results of verbal and haptic intelligence tests for the whole population of the visually impaired, braille-educated Dutch children and Dutch-speaking children in Belgium. The scores of children with and without usable vision generally confirmed expectations. Children with usable vision had higher spatial test scores. Those without usable vision did better on verbal memory tests and school-achievement tests for writing accuracy and technical reading. Children in regular or integrated education scored higher on verbal, reasoning and school-achievement tests. Evaluation of the effect of systematically varied task factors in four spatial tests indicated that, for two of the tests, having usable vision interacted with the task factors.
