Abstract

Children identified nonsense shapes by touch better with their left hand and words better with their right hand. Bigrams were processed by boys as shapes and by girls as words, which suggests a sexual dimorphism of brain functioning for bigrams. A relative specialization of the hemisphere for stereognostic processing is also suggested, since the accuracy of identification by both hands was greater than chance for all three types of stimuli.
