The effects of grammatic class and cue type on cueing responsiveness in aphasia.

This study investigated the effects of two types of cues (semantic and phonemic) and two grammatic classes (noun and verb) on cueing responsiveness. Subjects consisted of 10 Broca's, 10 Wernicke's, 8 conduction, and 8 anomic aphasics. Cues were administered following failure to name on confrontation. Responsiveness to the two types of cues was dependent on aphasic type and grammatic class. Broca's and conduction aphasics responded better to phonemic cueing, while anomic aphasics were more responsive to semantic cueing. With regard to grammatic class, aphasics responded better to phonemic cueing on nouns; however, no significant difference between types of cues was demonstrated on verbs. Neuropsychological implications for the cueing and naming processes are discussed.
