Deaf Children's Judgments on Conservation Problems of Liquid, Matter, Weight and Volume: A Pilot Study.
Rittenhouse, Robert K.
Twenty-four profoundly deaf children (7 to 13 years old) from a residential school were presented with conservation problems of liquid, matter, weight, and volume. Analyses of variance showed that age was significant beyond the .01 level and type of task (conservation) at the .25 level. No significant sex effect was found. Differences among means were computed and suggested the following order of acquisition: volume-matter-weight-liquid. This order was in disagreement with the order established by J. Piaget with nonhandicapped children; and, in regard to volume, significantly different from the order established by Affolter with deaf children. The developmental reversal of both liquid and volume, the two forms which are acquired approximately 5 years apart in hearing children, seriously weakens H. Furth's position that deaf and hearing children do not essentially differ regarding cognitive development and his argument regarding the relationship of language and cognition during the concrete operational stage of development.
