“…Spontaneous elicitation requires initiation and full planning of a motor speech gesture, whereas the task of utterance completion provides a model of the expected response. Previous work has indicated an effect of task, whether spontaneous or performed following an external model, on motor and speech gestures (Kempler & Van Lancker, 2002;Sidtis, Rogers, Godier, Tagliati, & Sidtis, 2010). In contexts where participants must initiate, program, and plan a gesture-whether of gait, arm, or speech-performance is measurably worse than in contexts where a model, exemplar, guideline, or aid to the gesture is provided (e.g., Burleigh et al, 1997;Georgiou et al, 1993;Weiss et al, 1997).…”

Purpose: The production of formulaic expressions (conversational speech formulas, pause fillers, idioms, and other fixed expressions) is excessive in the left hemisphere and deficient in the right hemisphere and in subcortical stroke. Speakers with Alzheimer's disease (AD), having functional basal ganglia, reveal abnormally high proportions of formulaic language. Persons with Parkinson's disease (PD), having dysfunctional basal ganglia, were predicted to show impoverished formulaic expressions in contrast to speakers with AD. This study compared participants with PD, participants with AD, and healthy control (HC) participants on protocols probing production and comprehension of formulaic expressions. Method: Spontaneous speech samples were recorded from 16 individuals with PD, 12 individuals with AD, and 18 HC speakers. Structured tests were then administered as probes of comprehension. Results: The PD group had lower proportions of formulaic expressions compared with the AD and HC groups. Comprehension testing yielded opposite contrasts: participants with PD showed significantly higher performance compared with participants with AD and did not differ from HC participants. Conclusions: The finding that PD produced lower proportions of formulaic expressions compared with AD and HC supports the view that subcortical nuclei modulate the production of formulaic expressions. Contrasting results on formal testing of comprehension, whereby participants with AD performed significantly worse than participants with PD and HC participants, indicate differential effects on procedural and declarative knowledge associated with these neurological conditions. C linical descriptions of formulaic language in aphasic speech have flourished for more than 150 years under a wide variety of terms. Formulaic language, in its modern conception, consists of fixed, unitary expressions known to a language community with their characteristic form, meaning, and usage conditions. Typical examples are conversational speech formulas ("You betcha," "You've got to be kidding," and "Say what?"), expletives ("heck"), idioms ("as the crow flies," "That's the way the cookie crumbles"), proverbs ("When it rains, it pours"), and other conventionalized expressions ("all things being equal," "in the meantime," and "the long and the short of it is"; Altenberg, 1998;Biber, 2009;Kuiper, 2004;Wray, 2002). These expressions share the features of fixed or canonical form; conventionalized, often nonliteral meaning; and specific relations to discourse context.As reviewed in Van Lancker (1973, 1975, 1994, formulaic language has its venerable beginnings in observations by J. Hughlings Jackson (1874aJackson ( /1932Jackson ( , 1874bJackson ( /1932, who labeled the preserved expressions seen in adults with language disability following left-brain damage automatic or nonpropositional speech. Examples cited by Hughlings Jackson include phrases belonging classically to the conception of formulaic expressions: "Take care," "That's a lie," "Good bye," "Oh dear," and "Bles...

“…5(8), 1760-1763 1761 and normal's. Results show that the normal's were having the highest mean intelligibility in normal's which is then followed by the ALS group then by PD group for the sentence intelligibility task (Weismer, Jeng, Laures, Kent & Kent, 2001) .According to Kempler & Lancker, 2002, speech production efficacy varies with tasks. Hustad, 2007 measured speech intelligibility using transcription and rating scale in different types and severity of dysarthria across three different types of speech stimuli.…”

“…A leitura-em-voz-alta é representativa da produção de discurso espontâneo, e deve ser avaliada utilizando um texto foneticamente equilibrado (TFE) construído especificamente para a língua padrão da população a que se destina (Kempler & Van Lancker, 2002;Lowit-Leuschel & Docherty, 2001). A aplicação um TFE em sujeitos com alterações motoras da fala permite recolher dados acerca das PMF e estudar o impacto destas patologias nas competências comunicativas (Baken & Orlikoff, 2000;Lowit-Leuschel & Docherty, 2001).…”

“…Um grau elevado de fiabilidade aumenta a confiança dos profissionais e investigadores face à utilização de um instrumento (Ferreira & Marques, 1998;Maroco & Garcia-Marques, 2006;SACMOT, 2002;Terwee et al, 2007) É importante dotar os profissionais de saúde de competências e ferramentas que auxiliem na identificação precoce das PMF, pelo impacto que estas têm nas competências sócio comunicativas e qualidade de vida do sujeito. Torna-se emergente a utilização de um instrumento válido, fiável e de aplicação rápida, que analise as características da fala, permitindo a realização de rastreios, a atribuição de um diagnóstico e a elaboração de um plano terapêutico eficaz para cada sujeito (Kempler & Van Lancker, 2002;Tjaden & Wilding, 2011;Villaseñor-Pineda & Montes-yGómez, 2004).…”
