Experimental Word Learning in Children With and Without Language Impairment

January 22, 2008 updated by: University of Sao Paulo

Experimental Word Learning in Children With Normal Development and Children With Language Impairment

The purpose of this study is to compare the performances of normally developing children and children with Language Impairment (LI) in three different experimental settings designed to promote vocabulary acquisition. This comparison will also provide evidence to support different intervention approaches designed to increase vocabulary abilities, which has been proved to be one of the major deficits of young children with LI.
