Disorders of vocal emotional expression and comprehension: The aprosodias
2021, Handbook of Clinical NeurologyCitation Excerpt :The authors attributed the bilateral activations to the automatic speech task. Although automatic or “nonpropositional” speech (Jackson, 1874) is sometimes relatively preserved in patients with nonfluent aphasias (Lum and Ellis, 1994), suggesting that it may be motorically controlled by the right hemisphere (Graves and Landis, 1985), aphasic nonfluency with or without preservation of automatic speech is not observed after RBD (Ross and Monnot, 2008). Furthermore, all subsequent functional imaging studies using PET or fMRI have consistently demonstrated, on low-level subtraction (activated minus resting-state scans), a rather robust symmetrical activation of, at a minimum, both temporoparietal opercular regions when probing the verbal–linguistic aspects of language (Van Lancker Sidtis, 2006; Sidtis, 2007) even though focal lesions involving the right temporoparietal opercular region are not associated with aphasic deficits (Ross and Monnot, 2008).
Cortical-subcortical production of formulaic language: A review of linguistic, brain disorder, and functional imaging studies leading to a production model
2018, Brain and CognitionCitation Excerpt :The results were comparable for English, German, and Chinese (Blanken, 1991; Chung, Code, & Ball, 2004; Code, 1982). Structured testing comparing automatic and propositional speech production and comprehension in aphasia further verified this dual functionality (Lum & Ellis, 1994; Van Lancker Sidtis & Yang, 2016). Persons with the diagnosis of transcortical sensory aphasia (Berthier, 1999) or with semantic deficits due to isolation of the speech area, while having severely impoverished semantic competence, are able to complete formulaic expressions, such as idioms and proverbs (Nakagawa et al., 1993; Sidtis, Canterucci, & Katsnelson, 2009; Whitaker, 1976).
The effects of initiation, termination and inhibition impairments on speech rate in a case of progressive nonfluent aphasia with progressive apraxia of speech with frontotemporal degeneration
2013, Journal of NeurolinguisticsCitation Excerpt :The comparison with the performance of the controls is shown in Fig. 3. Automatic counting requires self-initiation rather than an external trigger to initiate, apart from the examiner's request to count to thirty, and is considered perhaps the most automatic of speech tasks (Lum & Ellis, 1994; Code, 1997) entailing as it does the automatic recitation of an over learnt sequence. It is less demanding than reading a passage aloud, but does not entail repetition or reading.
