Visual dimensional dominance and haptic form recognition

Abstract

Eighty-two preschool children were assessed for dimensional dominance by asking them to make similarities judgments about two dimensional geometric figures varying in form, color, and size. They also participated in two tests of haptic form recognition of three dimensional forms, once with one hand and once with two hands. The results indicate that recognition performance of form dominant subjects was substantially superior to the performance of nonform subjects. Children of mixed dominance improved on the second test, generating a significant type of Dominance by Tests interaction. Order of administration of dominance and haptic tests had no significant influence on recognition performance.
