Research Design: Single Case Design

A multiple baseline single-subject experimental design was employed to study effects of a sentence stimulation treatment on sentence production in an aphasic patient with agrammatism. Prior to this seven-week study, the subject had not been using speech functionally for six months. Treatment was applied sequentially across three sets of picture stimuli. Performance was measured with probes of verbal description for each set. Results showed that treatment influenced description of the pictures being treated and that some generalization occurred with sets not being treated. However, formal pre-post testing indicated that a broader effect had not been obtained.
