Spontaneous speech in senile dementia and aphasia: Implications for a neurolinguistic model of language production

Gerhard Blanken; Jürgen Dittmann; J.-Christian Haas; Claus-W. Wallesch

Abstract We analyzed spontaneous speech production in semi-standardized interviews conducted with 10 patients suffering from moderate senile dementia of the Alzheimer type (SDAT), 5 Wernickes aphasics, and 5 elderly controls without brain damage. Data analysis revealed in both patient groups a reduction of sentence length but absence of systematic paragrammatic symptoms on the part of the demented patients. A relatively selectively diminished use of nouns was striking in the production of both patient groups, whereas word finding ability was surprisingly well preserved in the SDAT patients. Both patient groups exhibited marked deficits but different patterns of pathological behaviour on the discourse level of responding to the interviewers questions. Results are interpreted within a proposed neurolinguistic language production model. It is argued that the formulation process may be preserved in demented patients but is disturbed in aphasia. Language-related disturbances in senile dementia are assumed to result from pre-linguistic disorders in the formation of the conceptual structure of the intended speech act.

Producing speech automatisms (recurring utterances): Looking for what is left

Gerhard Blanken; Jürgen Dittmann; J.-Christian Haas; Claus-W. Wallesch

Abstract Nine expressively severely impaired aphasics with a predominant production of syllabic speech automatisms (e.g. do-do-do) were investigated. Firstly, the group respected differential length types in relation to three types of questions (yes/no, wh-questions and narrative requests) in a standardized interview. Secondly, preserved articulatory and phonological capacities in series and syntagmatic cueing conditions were found in a subgroup. Finally, observations in written language suggest that automatisms are restricted to oral speech. Results are discussed within the framework of a language production model.

Implications of preserved written language abilities for the functional basis of speech automatisms (recurring utterances): A single case study

Gerhard Blanken; Ernst G. de Langen; Jürgen Dittmann; Claus W. Wallesch

Abstract A patient is described whose oral speech consists exclusively of repetitively used stereotypical utterances (speech automatisms) but whose written performance is far better preserved. Written language investigation revealed that his phonological route for writing was not totally blocked. In writing to dictation, word length and syllabic structure were largely respected, even for nonwords. Picture-matching tasks which manipulated phonological similarity demonstrated relatively preserved access to lexical phonology. A nonlexical and sub-phonemic hypothesis of automatism-generation is proposed.
