Experimental Word Learning in Children With and Without 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.
