The purpose of this article is to analyze the results of a study of the development of analogical reasoning in deaf children coming from two different linguistic environments (deaf children of deaf parentssign language, deaf children of hearing parentsspoken language) and in hearing children, as well as to compare two groups of deaf children to a group of hearing children. In order to estimate the development of children's analogical reasoning, especially the development of their understanding of different logical relations, two age groups were singled out in each population of children: younger (9- and 10-year-olds) and older (12- and 13-year-olds). In this way it is possible to assess the influence of early and consistent sign-language communication on the development of the conceptual system in deaf children and to establish whether early and consistent sign-language communication with deaf children affects their mental development to the same extent as early and consistent spoken-language communication with hearing children. The children were given three series of analogy tasks based on different logical relations: (a) a series of verbal analogy tasks (the relations of opposite, part-whole, and causality); (b) a series of numerical analogy tasks (the relations of class membership, opposite, and part-whole); and (c) a series of figural-geometric analogy tasks (the relations of opposite and part-whole). It was found that early and consistent sign-language communication with deaf children plays an almost equivalent role in the development of verbal, numerical, and spatial reasoning by analogy as early and consistent spoken-language communication with hearing children.
