THE DEVELOPMENT OF ANALOGICAL REASONING IN DEAF CHILDREN
AND SIGN LANGUAGE COMMUNICATION


Abstract. The purpose of this article is to analyze the results of study on t.hc develop-
ment of analogical reasoning in deaf children coming from two different linguistic envi-
ronments (deaf children of deaf parents - sign language, deaf children of hearing par-
ents - spoken language) and hearing children as well as to compare two groups of deaf
children to group of hearing children. In order to estimate the development of analogi-
cal reasoning, especially the development of understanding the different logical rela-
tions, 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 connection it is possible to assess
the influence of early and consistent sign language communication on the development
of conceptual system in deaf children, also to establish whether early and consistent
sign language communication in the case of deaf children determines the mental devel-
opment to an equal extent as early and consistent spoken language communication in
the case of hearing children. The children were given three series of analogy tasks
based on the different logical relations: l. Series of verbal analogy tasks (the relations
of opposite, part-whole and causality); 2. Series of numerical analogy tasks (the rela-
tions of class membership, opposite and part-whole); 3. Series of figural-geometric anal-
ogy tasks (the relations of opposite and part-whole). It was found that early and consis-
tent, sign language communication in the case of deaf children plays an almost equiva-

lent role in the development of verbal, numerical and spatial reasoning by analogy as early and consistent spoken language communication in the case of hearing children.
