The following study had been developed to demonstrate language behavior in subjects that matched or demonstrated deficient language behavior like Sarah's (Premack, 1971). Two autistic children were selected as subjects. These two subjects demonstrated that children who could not normally fulfill the language behavior requirement of selecting specific words, letters, or colored stones, and arranging them in some good temporal sequence, could in fact be taught to do just that activity. In this manner, language deficient candidates more severely damaged than the subjects used by Premack in his study on language difficulties in persons who were "brain damaged,'" could be taught the parameters of syntax and semantics on a non-vocal level, and thereby fulfill the criterion for language behavior, namely that of arranging specific symbols in good temporal sequence.
