Abstract

The production of aphasic lexical speech automatisms (yes and right) produced by C.S., a man with progressive speech impairment and primary progressive nonfluent aphasia, were analysed across a range of takes varying in complexity. More automatisms were produced during single word and nonword reading and repetition and picture description than during connected reading and counting, suggesting that internally generated (picture description) and externally triggered (single word and nonword reading and repetition) were equally affected. In addition, a complex speech task (connected reading) produced then fewest automatisms than easier ones (single words). However, tasks where there were increased opportunities for disinhibition produced more automatisms. Results do not suggest that the intrinsic or extrinsic motor speech systems are separately damaged, but do suggest that increased opportunities for disinhibition may produce more automatisms.
