Title: Syllable structure and lexical frequency effects in the phonemic errors of four aphasics
Abstract: Four fluent aphasics were submitted to a repetition task including high-frequency words, lowfrequency words and non-words, varying with respect to syllable markedness. The word/nonword opposition is significant in the responses of all patients, while a frequency effect is observed in the responses of two of them. Results suggest that all stimuli are processed through a single route by these patients. It is proposed that lexicality (word vs non-word) and frequency effects are related to variations in the degree of automaticity reached in the processing of stimuli. A second experiment reveals that length, rather than syllable complexity, is the structural factor with the most significant impact on performance. A qualitative analysis demonstrates, however, that syllable is a relevant structural unit at the psycholinguistic level.
