Sl. Schneider et al., EFFECTS OF VERBAL PLUS GESTURAL MATRIX TRAINING ON SENTENCE PRODUCTION IN A PATIENT WITH PRIMARY PROGRESSIVE APHASIA, Aphasiology, 10(3), 1996, pp. 297-317
This research examined the effectiveness of verbal plus gestural treat
ment on the acquisition and generalization of present, past and future
verb tenses in NP + V + NP sentence production in a primary progressi
ve aphasic subject. Using a single-subject multiple-baseline design ac
ross behaviours as well as a matrix training procedure, treatment and
generalization effects both within and across language matrices were e
xamined. The relation between gestural and verbal responding was also
examined post-hoc using a modified reversal design component. Results
indicated improved production of sentences utilizing trained verb tens
es and generalization to untrained verbs within tense. Paired gestural
plus verbal responding resulted in higher levels of correct oral sent
ence production than verbal training alone. Findings are discussed in
the context of brain mechanisms underlying gestural and verbal languag
e production.
