Abstract

The ability of RHD patients to use context under conditions of increased processing demands was examined. Subjects monitored for words in auditorily presented sentences of three context types-normal, semantically anomalous, and random, at three rates of speech normal, 70% compressed (Experiment I) and 60% compressed (Experiment 2). Effects of semantics and syntax were found for the RHD and normal groups under the normal rate of speech condition. Using compressed rates of speech, the effect of syntax disappeared, but the effect of semantics remained. Importantly. and contrary to expectations, the RHD group was similar to normals in continuing to demonstrate an effectof semantic context under conditions of increased processing demands. Results are discussed relative to contemporary theories of laterality, based onstudies with normals, that suggest that the involvement of the left versusright hemisphere in context use may depend upon the type of contextual information being processed.
