Effects of iconicity, motoric complexity, and linguistic function on sign acquisition in severe aphasia.

The influence of three features of manual signs (iconicity, motoric complexity, linguistic function) on their successful acquisition by aphasic subjects was investigated. 12 severe chronic aphasic subjects were presented 37 signs in a training program for the production of manual signs. Analysis indicates that the three signs features affected the successful acquisition of signs. As a group the subjects acquired a larger percentage of high and medium iconic than of low iconic signs; a larger percentage of low and medium motorically complex signs than high; and a larger percentage of verb than noun or adjective signs. The implications of these findings with regard to selecting a manual sign vocabulary for training are discussed.

What makes a therapy? Some parameters of therapeutic intervention in aphasia.

It has often been assumed that detailed analyses of aphasic impairments would be both necessary and sufficient for the development of remediation programmes. In this paper, we argue that the analysis of the impairment is a necessary but not sufficient precondition for therapy. Adequate remediation programmes require the development of an independent theory of therapy that provides a detailed specification of the different components of the therapeutic process. Therapy can be shown to have as many interacting components as the impairment itself. In this paper, we try to identify some of the components of the therapy process by comparing different therapy programmes that have been employed in the remediation of 'mapping deficits' in agrammatism.
