An analysis of the word-finding difficulties and of the content of the content of the discourse of recent and chronic aphasic speakers, Aphasiology, 11:8, 783-811,
AbstractThis study examined the changes in the discourse produced by recent and chronic aphasic speakers while describing the bank robbery picture from the Montrtal-Toulouse protocol (Nespoulous e t al. 1986) at two different assessments, on average 6 weeks apart. The manifestations of word-finding difficulties, content unit production and several efficacy of communication indices were analysed. No statistical improvement of word-finding difficulties or of content unit production was found in the discourse in the recent aphasic group. Overall, both groups were more efficient on the second assessment on the index of number of open-class words per unit of time. Significant correlations were observed between aphasia severity and content unit production, as well as with the efficacy of communication indices.
Intonation characteristics (mean F0, standard deviation of F0, and F0 difference) and speaker rate (duration) were assessed in 40 matched statement–question pairs produced by 40 normal adult speakers of Canadian French, similar to Eady and Cooper [J. Acoust. Soc. Am. 80, 402–415 (1986)] for American English. Subgroups were also compared by both sex (male versus female) and age (younger versus older subjects). Results revealed a greater difference in fundamental frequency between statement–question pairs than reported by Eady and Cooper, as well as a previously unreported interaction between sentence duration and sentence type. There were also age-related differences in both intonation and rate.
