Grosso modo, o prompting é entendido como uma pista articulatória isto é, a execução, pelo interlocutor, do primeiro gesto ou das primeiras sequências de gestos que compõem as primeiras sílabas da palavra requerida. Não obstante a pouca clareza sobre os aspectos envolvidos em seu funcionamento, tem sido mencionado na literatura clínica quando da referência às estratégias terapêuticas utilizadas na recuperação da linguagem por afásicos. Via de regra, nesses estudos, o terapeuta fornece ou estimula o prompting oral ou escrito ao paciente. Com isso, perdem-se de vista vários aspectos constitutivos do fenômeno. A presente pesquisa tem como objetivo qualificar e caracterizar a emergência do prompting na linguagem de afásicos em meio às atividades interativas desenvolvidas no Programa de Linguagem do Centro de Convivência de Afásicos (CCA), localizado no Instituto de Estudos da Linguagem/Universidade Estadual de Campinas (IEL/UNICAMP). Ao tomá-lo como fenômeno a ser analisado, pretendemos definir melhor os contornos conceituais e explicativos do prompting, em suas diversas configurações e modalidades, descrevendo as condições e o contexto lingüístico-interacional propício a sua ocorrência, bem como a sua relação com as características de linguagem dos sujeitos afásicos. Além disso, objetivamos a caracterizar o que motiva os afásicos a selecionarem, na resposta ao prompting, por uma produção oral, escrita ou gestual. O empreendimento analítico das implicações do prompting permite-nos uma melhor compreensão do que ocorre mais especificamente no contexto das afasias, a fim de que possamos estabelecer as relações necessárias acerca do fenômeno e possamos, com isso, agregar novos conhecimentos para a área dos estudos interacionais e conversacionais no campo da Linguística, além de contribuir para as investigações clínicas que objetivam a auxiliar os afásicos em suas dificuldades de comunicação e significação / Abstract: Our purpose in undertaking a linguistic-interactional study of verbal prompting, as well as its explanatory gains for the context of aphasia research, has arisen from the conceptual imprecision of the phenomenon. Roughly speaking, prompting is understood as an articulation cue, that is, the execution by the recipient, or the first act of the first sequences of gestures that forms the first syllables of the word required. The lack of clarity on some aspects involved in its functioning, verbal prompting is usually mentioned in the clinics literature when one refers to the therapeutical strategies used in language recovery by aphasics. As a rule in these studies the therapist provides or stimulates spoken or written prompting to the patient. Therefore various aspects of the phenomenon are lost of sight. This research aims to describe and characterize the emergence of prompting in aphasic language through interactive activities developed in the Language program of Centro de Convivência de afásicos (CCA), located at the Institute of Language Studies/ Universidade Estadual de Campinas (IEL/Unicamp). By taking it as a phenomenon to be analyzed, we intend to further define and explain the conceptual contours of prompting, in its various settings and types, describing the conditions and interactional-linguistic context to its occurrence and its relationship with the characteristics of the aphasic language. Furthermore, we aimed to characterize what motivates aphasics to choose, in response to prompting by an oral production, written or sign language. The development of the analytical implications of prompting allows us as better understanding of what occurs specifically in the context of aphasia, in order that we may establish the necessary links about the phenomenon and can, therefore, besides adding new knowledge to the area of interactional and conversational studies in the field of linguistics, contribute to the clinical investigations that aim to assist aphasic subjects in their difficulties to communicate and significate / Doutorado / Linguistica / Doutora em Linguística

A narrativa, dessa forma, pode ser compreendida também como uma metodologia que possibilita eliciar dados singulares, uma vez que são produzidos em situações efetivas de uso da linguagem. Para o desenvolvimento do trabalho, foram selecionados onze episódios narrativos, produzidos dialogicamente entre sujeitos afásicos e não-afásicos em sessões coletivas e individuais do Grupo III do Centro de Convivência de Afásicos (CCA), vídeo-gravados e posteriormente transcritos e analisados segundo metodologia qualitativa, de cunho indiciário (cf. GINZBURG, 1986/1989). Todos os sujeitos afásicos que participaram desta pesquisa produziram narrativas, mesmo aqueles com afasias consideradas graves do ponto de vista da produção. Buscamos analisar os elementos constitutivos de cada episódio narrativo considerando-se as categorias postuladas por Labov & Waletsky (1967) e mobilizando também conceitos bakhtinianos para explicitar os processos que os afásicos percorrem para se aproximar de seu querer-dizer (como enunciado, acabamento, conclusibilidade etc), assim como questões relativas à ética que deve orientar os processos terapêuticos. As práticas sociais de linguagem, em situações de uso efetivo, possibilitam que o afásico exerça seu papel de sujeito ativo nos círculos sociais dos quais faz parte, mesmo nos casos considerados "graves". O trabalho orientado pelas teorias enunciativodiscursivas privilegia os sujeitos e não a sua patologia; dão vez e voz aos afásicos, demanda que o seu interlocutor se constitua verdadeiramente como "parceiro da comunicação verbal" (cf. BAKHTIN, 1979/2010), que se coloque disponível para a escuta (cf. PONZIO, 2010) / Abstract: The main goal of this thesis is to present and discuss the narrative discourse - which was found to be the most resistant in aphasia - as (i) a privileged locus for the analysis of its impact on language, either on the linguistic system (to evaluate, for instance, the difficulties of selection and combination of linguistic elements - phonetic/phonological, syntactic and lexical-semantic), as well as concerning pragmatic and discursive aspects; (ii) as a context in which one can observe and analyze the creative solutions found by the aphasics in order to face their difficulties; (iii) as a locus for the linguistic/cognitive reorganization during the therapeutic follow-up. Narrative discourse, this way, may be understood as a methodology which makes it possible to elicit singular data, once they are produced in effective use of language. To develop the work, eleven narrative episodes were selected, which were produced dialogically between aphasic and non-aphasic subjects during individual sessions and group meetings of Group III of Centro de Convivência de Afásicos (CCA). Data were videorecorded, afterwards transcribed and analyzed according to qualitative methodology, of evidentiary nature (cf. GINZBURG, 1986/1989). All the aphasic subjects who participated in this research produced narratives, even those that can be considered to have severe aphasia, from the perspective of production. We sought to analyze the constitutive elements of each narrative episode, taking into consideration the categories postulated by Labov & Waletsky (1967) and also mobilizing bakhtinian concepts to explicit the paths which aphasics follow in order to approach their speech-will, as well as questions concerning the ethics that must guide the therapeutic processes. The social practices, in situations of effective use of language, make it possible to the aphasics to play the role of active subjects in the social circles they participate, even in severe cases. The work guided by enunciative-discursive theories privileges the subjects, not pathologies; it gives voice to the aphasics (and restitutes them their turn); it demands that the interlocutor of the aphasic becomes truly the partner of the verbal communication (cf. BAKHTIN, 1979/2010); it demands that he (the partner) puts himself available to listen to the aphasic (cf. PONZIO, 2010) / Doutorado / Linguistica / Doutor em Linguística

Com base na Neurolingüística discursivamente orientada, na Neuropsicologia luriana e nas bases biológicas da Neuroplasticidade, estuda-se a complexidade dos processos envolvidos em atividades realizadas por JS, destacam-se as estratégias discursivas utilizadas por ele para disfarçar suas dificuldades, bem como os procedimentos clínicos com função terapêutica usados pela investigadora/interlocutora na tentativa de ¿(re)orientar¿ a reflexão de JS sobre as atividades realizadas. O foco deste estudo de caso, portanto, é a relação entre corpo/espaço e linguagem envolvida em atividades que requerem um bom funcionamento dessa relação. Para isso, toma-se como ponto de referência o sujeito que se enuncia para organizar o espaço da enunciação e seu próprio corpo como mediador dessa relação, o que permitiu compreender suas dificuldades e as soluções que encontra. Para análise e discussão dos dados foi utilizada uma metodologia qualitativa e heurística, baseada no paradigma indiciário, compatível com a formulação teóricometodológica de dado-achado. Os dados analisados mostram que JS se beneficiou do acompanhamento longitudinal: em relação a seu corpo, passou a observá-lo mais e a usar as referências que nele existem para determinar as coordenadas espaciais, direita e esquerda, relacionando-as a objetos representados; em relação à escrita, passou a concebê-la de novo como escrita e organizá-la melhor no espaço do papel; em relação à leitura das horas, refaz suas hipóteses na interlocução, havendo maior dificuldade quando a leitura não é feita em seu relógio de pulso, ou seja, quando o corpo não está concernido. Em relação à interlocução, JS revela muita eficácia no jogo da linguagem, transferindo para o outro o ônus da resposta, não apresentando, pois, o ideário de um sujeito com demência / Abstract: The objective of this research is investigating how our non-aphasic subject ¿ JS ¿ behaves after undergoing three ischemic vascular cerebral accidents, the way heaccomplishes some linguistic-cognitive activities evolving visual-spatial aspects related to his body, reading and writing, and time checking on clocks. Based on discursive-oriented Neurolinguistics, on Lurian Neuropsychology and on biological bases of Neuroplasticity, we study the processes complexity evolved in the activities performed by JS. We highlight the discursive strategies he used in order to hide his difficulties, as well as the therapeutically functional clinic procedures employed by the investigator/interlocutor when trying to ¿(re)guide¿ JS reflections about the activities performed. This case study focus is, therefore, the relation established between, on one hand, body/space and, on the other hand, the language required for the good functioning of this relation. Aiming that, we consider, as a reference point, the subject that enunciates himself in order to organize the enunciation space, using his own body as a broker of this relation ¿ which permits the comprehension of his difficulties and the solutions he is able to find. In order to analyze and discuss data, we backed on a qualitative and heuristic methodology, base don the indiciary paradigm, compatible to the theoretical-metodological analisis of ¿found data¿. The data analyzed shows that JS benefited himself from the longitudinal companion: he¿s started to observe his own body, using it to determine special coordinates (like left and right), in order to be able to relate these coordinates to represented objects; regarding writing, he¿s also conceived it as writing in fact; regarding time reading on the clock, he restated his own interlocution, mainly when he was not checking his own watch ¿ i.e., when his own body was not evolved. Regarding interlocution, JS reveals a lot of efficiency in the language game by transferring to his interlocutor the weight of the response ¿ i.e., not showing the ideary of a dement person / Mestrado / Mestre em Linguística

Na primeira parte, foram elencadas e discutidas questões epistemológicas de base para as pesquisas que adotam a abordagem enunciativo-discursiva, dentre as quais a relação entre sinal/sintoma e síndrome. Para iniciar a discussão, partimos do próprio conceito de semiologia, sempre marcado pela relação entre ver e dizer, conforme aponta Focault. Outras noções também são mobilizadas, por serem essenciais para o tratamento do tema, como a relação entre normalidade e patologia, bem como as concepções de cérebro, sujeito e linguagem que permeiam as pesquisas realizadas no período. A segunda parte reúne trabalhos desenvolvidos na Neurolingüística de abordagem enunciativo-discursiva, no IEL, nos últimos 25 anos e que discutem termos e categorias correntemente utilizados na semiologia das afasias. É necessário esclarecer que o nosso recorte visa trazer para análise apenas os trabalhos que se ocupam de itens semiológicos, mesmo que estes não sejam o ponto central da pesquisa. Selecionamos, nos trabalhos, a reflexão crítica acerca das seguintes terminologias: agramatismo (Coundry, 1986; Guindaste, 1996; Novaes-Pinto, 1992, 1997 e 1999; Kleppa, 2008); fala telegráfica (Novaes-Pinto, 1992 e 1999; Kleppa, 2008); anomia (Rajer, 2010); automatismo e estereotipia (Viscardi, 2005 e 2010); circunlóquio, digressão e confabulação (Morato, 1995 e 2010; Canoas-Andrade, 2009); jargonafasia (Morato e Novaes-Pinto, 1997; Novaes-Pinto; Morato, 1998; lshara, 2004); neologismos (Morato; Novaes-Pinto,1998); parafasia (Rapp, 2003; Reisdorfer, 2007; Túbero, 2010); perseveração (Saraiva, 2004); e síndrome frontal leve (Gandolfo, 1994). Nas Considerações de Passagem, nos questionamos se é possível uma abordagem não-dicotômica para a caracterização dos fenômenos e recorremos a Jakobson (1956), Coundry (2001) e Fedosse (2008) / Abstract: This research aimed to (i) resume conceptual issues and basic guidelines of enunciative-discursive Neurolinguistics, (ii) present case studies developed in the area within the last 25 years, pointing to what unites them under this specific approach we call socio-historical-cultural, explaining how the area has been refining both theoretical and methodological assumptions, resignifing old terms and proposing others, critically discussing the semiology of aphasia. In the first part, issues of epistemological basis for researches which adopt this approach were listed and discussed, among which the relationship between sign/symptom and syndrome. We start from the very concept of semiology, always marked by the relationship between seeing and saying, as Foucault indicates. Other concepts are also mobilized, because they are essential to the adequate treatment of the topic, such as the relationship between normality and pathology as well as the notions of brain, subject and language that permeate the research conducted in the period. The second part consists on presenting some of the research developed in the enunciative-discursive approach, at IEL in the last 25 years and discuss terms and categories currently used in the semiology of aphasia. It is necessary to clarify that we aim to analyze only the works which deal with semiological items, even if these are not the focus of one specific research. We have selected, from researches, critical reflection about the following terminology: agrammatism (Coudry, 1986; Guindaste, 1996; Novaes- Pinto, 1992 , 1997 and 1999; Kleppa, 2008); telegraphic speech (Novaes-Pinto, 1992 and 1999; Kleppa, 2008); anomia (Rajer, 2010); stereotyped and recurrent utterances (Viscardi, 2005 and 2010); circumlocution, digression and confabulation (Morato, 1995 and 2010; Canoas-Andrade, 2009); jargonaphasia (Morato and Novaes-Pinto, 1997; Novaes-Pinto and Morato, 1998; Ishara, 2004), neologism (Morato, Novaes-Pinto, 1998); paraphasia (Rapp, 2003; Reisdorfer, 2007; Tubero, 2010); perseveration (Saraiva, 2004); and light frontal syndrome (Gandolfo, 1994). In the last part, which we called Considerations of passage, we ask ourselves whether it is possible to characterize phenomena using a non- dichotomous approach or not. For that specific issue, we recur to Jakobson (1956), Coudry (2001) and Fedosse (2008). / Mestrado / Linguistica / Mestre em Linguística

Two conflicting findings characterize cognitive processing accompanying bilingualism. The “bilingual advantage” refers to improved cognitive performance for bilingual compared to monolingual participants. Most bilingual advantages fall under the umbrella of cognitive control mechanisms, most frequently demonstrated using the Stroop task and the Simon task (e.g., Bialystok, 2008; Coderre, Van Heuven, & Conklin, 2013). The “bilingual disadvantage,” on the other hand, refers to bilinguals’ diminished performance on tasks that require word retrieval or switching between languages. This study examined the intersection of the bilingual advantage and the bilingual disadvantage to investigate whether they stem from a single cognitive control process. The bilingual advantage was measured as speech onset time differences between monolingual and bilingual participants in the Stroop task after being primed in the same language (i.e., English prime and English Stroop for monolinguals, and either English prime and English Stroop or Spanish prime and Spanish Stroop for bilinguals). The bilingual disadvantage was measured as differences in bilingual participants’ speech onset times between the same-language conditions described above and cross-language conditions (i.e., either English prime and Spanish Stroop or Spanish prime and English Stroop). Monolinguals performed better than bilinguals did on the same-language Stroop [F(3,1) = 83.5, p < 0.001, MSE = 15415], so a bilingual advantage was not demonstrated. However, bilinguals did perform better in same-language blocks than cross-language blocks [F(7,3) = 24.6, p < 0.001, MSE = 22648]. This suggests that the current protocol successfully elicits the bilingual disadvantage. Further research is needed to evaluate whether the same cognitive control processes are responsible for the two effects. Possible extensions of this work include observing a larger number of participants to rule out between-subjects effects and using a button press rather than spoken response during the Stroop task.

Este trabalho teve como objetivo observar, analisar e discutir como ocorre a busca por sinais-alvo, em indivíduos surdos, fluentes na Língua Brasileira de Sinais (Libras); verificar se ocorre, nesses indivíduos o fenômeno ponta dos dedos (TOF); e descrever os aspectos fonético-fonológicos na ocorrência do fenômeno. O TOF corresponde ao fenômeno ponta da língua (TOT) nas línguas orais. Esse fenômeno ocorre quando há o esquecimento momentâneo de palavras conhecidas e o sentimento de que essa palavra está prestes a ser recuperada. Tal fenômeno oferece pistas sobre o processamento da linguagem e a recuperação lexical. Poucos trabalhos foram realizados sobre este fenômeno nas línguas de sinais (THOMPSON; EMMOREY; GOLLAN, 2005) e essa investigação é importante, pois, por ser uma língua de modalidade distinta (visual-espacial), possui processos fonológicos particulares. Nesse sentido, foi elaborado um teste para eliciar o fenômeno em 34 adultos surdos, que relataram utilizar a Libras como principal meio de comunicação. O teste consistia na realização do sinal referente a personalidades famosas e a cidades no mundo. Foram exibidas imagens e o participante deveria dizer se sabia ou não o sinal referente à pessoa ou à cidade, ou se estava experienciando o TOF. Neste último caso, o participante deveria sinalizar o que lembrasse do sinal- alvo. Foram realizados 69 estímulos por participantes, somando um total de 2346 estímulos e, como resultado obtivemos a ocorrência de 20 TOFs (0,9% dos estímulos). Em todos os casos de TOF foi recuperado ao menos um dos parâmetros fonético-fonológicos (quais sejam, configuração de mão, localização/ espaço, orientação, movimento, número de mãos). Dos parâmetros fonético-fonológicos recuperados, a configuração de mão foi recuperada em 65% dos casos (13 vezes); a localização em 70% (14 vezes); o espaço em 85% (17 vezes); o movimento em 35% (7 vezes); a orientação em 50% (10 vezes); e o número de mãos em 90% dos casos (18 vezes). Corroboramos a conclusão de Thompson, Emmorey e Gollan (2005) de que o movimento é o parâmetro menos recuperado no momento do TOF. Esse fato pode indicar que os parâmetros localização, configuração de mão e orientação (mais recuperados no momento do TOF) constituem o onset da estrutura silábica do sinal, isto é, o segmento inicial do sinal. Além disso, a ocorrência do fenômeno ponta dos dedos na Libras ajuda a confirmar separação, no processamento da recuperação lexical em codificação semântica e codificação fonológica estabelecidas em modelos de recuperação de línguas orais (DELL, 1986; GARRETT, 1988; LEVELT, 1989). / The aim of this research is to analyze and discuss how the search for target signs occurs in the lexical retrieval in deaf people using Brazilian Sign Language (Libras); to verify if the \"tip of the fingers\" (TOF) phenomenon occurs; and describe the phonological aspects in the occurrence of the phenomenon. The TOF phenomenon mirrors the \"tip of the tongue\" phenomenon in oral languages. This phenomenon occurs when there is momentary forgetfulness of known words and the feeling that this word is about to be recovered. This phenomenon offers clues about language processing and lexical retrieval. Few studies have been carried out on this phenomenon in sign languages (THOMPSON; EMMOREY; GOLLAN, 2005) and this research is important because sign language has a different modality and therefore it has particular phonological processes. In this sense, a test was prepared to elicit the phenomenon in 34 deaf adults, who reported using Libras as the main means of communication. The test consisted of the signing regarding proper names of famous personalities and cities in the world. Images were displayed and the participant should say whether or not he knew the sign for the person or city, or whether he was experiencing TOF. In the latter case, the participant should sign what he remembered of the target signal. A total of 69 stimuli were performed per participant, totaling 2346 stimuli and, as a result, we obtained the occurrence of 20 TOFs (0.9% of the stimuli). In all TOF cases, at least one of the phonological parameters (ie, hand configuration, location / space, orientation, movement, number of hands) was retrieved. Of those, the hand configuration was recovered in 65% of the cases (13 times); the location in 70% (14 times); space 85% (17 times); movement in 35% (7 times); orientation by 50% (10 times); and the number of hands in 90% of the cases (18 times). We corroborate the conclusion of Thompson, Emmorey and Gollan (2005) that movement is the least recovered parameter at the time of TOF. This fact may indicate that the parameters localization, hand configuration and orientation (more retrieved while in TOF state) constitute the onset of the syllabic structure of the sign. In addition, the occurrence of the \"tip of the fingers\" phenomenon in Libras helps to confirm separation, in the processing of lexical retrieval in semantic encoding and phonological encoding established in lexical retrieval models of oral language (GARRETT, 1988; LEVELT, 1989).

Η παρούσα εργασία εστιάζει στον τρόπο επεξεργασίας των σύνθετων λέξεων της Νέας Ελληνικής (ΝΕ) στην Πρωτοπαθή Προοδευτική Αφασία με αγραμματικό λόγο (ΠΠΑ-α). Οι μέχρι τώρα έρευνες επικεντρώνονται κυρίως σε κλινικές περι- πτώσεις αφασίας από κάποια εστιακή εγκεφαλική βλάβη (ΕΑ), ενώ η ΠΠΑ δεν έχει μελετηθεί ως προς το ζήτημα αυτό τόσο στη ΝΕ όσο και διαγλωσσικά. Στόχο, λοι- πόν, της συγκεκριμένης εργασίας αποτελεί η εξέταση του κατά πόσο ελληνόφωνοι ασθενείς με ΠΠΑ-α παρουσιάζουν ελλείμματα στην κατονομασία σύνθετων λέξεων. Μέθοδος: Διεξαγωγή πειράματος κατονομασίας μέσω ορισμού (naming on definition task), το οποίο αφορά την κατονομασία σύνθετων λέξεων της ΝΕ. Συμμετέχοντες: 2 ΠΠΑ-α ασθενείς (ο πρώτος σε πιο πρώιμο στάδιο της ΠΠΑ-α σε σχέση με το δεύτερο) και 2 άτομα που συνιστούν την ομάδα ελέγχου (controls). Πειραματικό υλικό: 71 σύνθετα της ΝΕ, 45 υποτακτικά (π.χ. μολυβοθήκη, μαυροπί- νακας, σιγοτραγουδώ), 15 παρατακτικά (π.χ. αλατοπίπερο, βορειοδυτικός) και 11 εξωκεντρικά (π.χ. κοκκινομάλλης, κακόγουστος).Υποθέσεις: Σύμφωνα με τα πορίσματα της τρέχουσας βιβλιογραφίας, ασθενείς με αγραμματικού τύπου ΕΑ και ΠΠΑ-α εμφανίζουν παρόμοια επίδοση σε πειράματα που ελέγχουν τη μορφοσύνταξη (Thompson et al.). Έτσι, αναμένεται να έχουν εξί- σου παρόμοια επίδοση και όσον αφορά την επεξεργασία συνθέτων, αφού η σύνθεση αποτελεί μία αμιγώς μορφολογική διαδικασία. Βάσει του παραπάνω παραλληλι- σμού, υποθέτουμε πως οι ΠΠΑ-α ασθενείς θα κατονομάζουν ευκολότερα τα σημα- σιολογικά διαφανή σύνθετα (πρώτη υπόθεση), θα διατηρούν τη γνώση της δομής του συνθέτου (δεύτερη υπόθεση), θα διατηρούν τα όρια των επιμέρους συστατικών σε πιθανά λάθη υποκατάστασης ή παράλειψης (τρίτη υπόθεση), και θα προβαίνουν σε ανάκληση του συνθέτου μέσω τεμαχισμού στα επιμέρους συστατικά του (τέταρτηυπόθεση). Τέλος, αν το συστατικό-κεφαλή έχει κάποιο βασικό ρόλο στη διαδικασία της κατονομασίας, αναμένονται συστηματικά περισσότερα λάθη σε αυτό το συστα- τικό (πέμπτη υπόθεση). Ακόμη, στο επίκεντρο του ενδιαφέροντος βρίσκονται και κάποια επιπλέον ερωτήματα που αφορούν το αν και κατά πόσο υπάρχει όντως σύ- γκλιση μεταξύ της ΠΠΑ-α και της ΕΑ-α στην κατονομασία σύνθετων λέξεων, το αν υπάρχει συσχέτιση μεταξύ του είδους/αριθμού των λαθών και του τύπου συνθέτου και το αν υφίστανται πρόβλημα με συστατικά συγκεκριμένης γραμματικής κατηγο- ρίας. Αποτελέσματα: Τα αποτελέσματα του πειράματος ανέδειξαν σημαντικές διαφορές στην επίδοση των δύο ασθενών. Ειδικότερα, ο πρώτος ασθενης είχε περισσότερα λάθη υποκατάστασης, τα οποία σηματοδοτούν επίγνωση της σύνθετης δομής και ανάκληση του συνθέτου μέσω τεμαχισμού στα επιμέρους συστατικά του. Αντίθετα, η δεύτερη ασθενής είχε περισσότερα λάθη περίφρασης και απάντησης με μία λέξη- λέξημα, ενώ ο στόχος ήταν η απάντηση με σύνθετη λέξη. Έτσι, τα λάθη της δεύ- τερης ασθενούς παραπέμπουν σε μη επίγνωση της σύνθετης δομής και σε μία πιο ολιστική διαδικασία ανάκλησης του συνθέτου. Τέλος, τα περισσότερα λάθη και των δύο ασθενών έγιναν σε υποτακτικά σύνθετα της γραμματικής κατηγορίας του ονό- ματος, ενώ δεν εντοπίστηκε επίδραση τόσο της σημασιολογικής διαφάνειας όσο και της μορφολογικής κεφαλής. Συμπεράσματα: Από την ανάλυση των αποτελεσμάτων γίνεται σαφές πως το στά- διο της διαταραχής καθορίζει και το είδος των γλωσσικών ελλειμμάτων. Συγκεκρι- μένα, στα πρώιμα στάδια της ΠΠΑ-α εμφανίζονται γλωσσικά ελλείμματα τα οποία συγκλίνουν με αυτά της ΕΑ-α, ενώ σε μετέπειτα στάδια η ικανότητα κατονομασίας πλήττεται σοβαρά διαμορφώνοντας ένα ιδιαίτερο κλινικό προφίλ, το οποίο δεν φαί- νεται να συγκλίνει ξεκάθαρα με κάποιον άλλο παθολογικό πληθυσμό. Αναλυτικό- τερα, στα αρχικά στάδια το πρόβλημα εδράζεται στην ενεργοποίηση της φωνολο- γικής μορφής της λέξης, ενώ οι μορφολογικοί κανόνες φαίνεται ότι διατηρούνται (γνώση της σύνθετης δομής, ορίων των συστατικών). Αντίθετα, σε μετέπειτα στά- δια το πρόβλημα εντοπίζεται στην ενεργοποίηση τόσο της φωνολογικής όσο και της μορφολογικής δομής του συνθέτου. Σε ό,τι αφορά τα υποτακτικά σύνθετα, η αυξη- μένη δυσκολία που δημιουργούν μπορεί να συσχετιστεί με τη λειτουργική σχέση των επιμέρους συστατικών τους. Εν κατακλείδι, η παρούσα εργασία αποτελεί μία πρώτη προσπάθεια μελέτης της σύνθεσης στην ΠΠΑ-α. Η ανάλυση των αποτελεσμάτων έφερε στο φως μία σειρά από γλωσσικά ελλείμματα, τα οποία αναμένεται να ελεγχθούν σε μεγαλύτερο δείγμα ΠΠΑ-α ασθενών για τον καθορισμό ασφαλέστερων συμπερασμάτων. / The present study is focused on the agrammatic variant of Primary Progressive Aphasia (PPA-a), which is a language impairment caused by neurodegenerative disease and characterized by difficulties in processing the grammatical aspects of speech (Mesulam, 2013). PPA-a has not examined about the grammatical deficits in Modern Greek (MG). Therefore, the aim of the present study is to examine if the Greek-speaking individuals with PPA-a have problems in naming compound words in MG. Procedure: Naming definition task of compound words in MG. Participants: Two patients with PPA-a (the first patient is in earlier stage of the disease than the other patient). Stimulus set: 71 compounds in MG, 45 subordinate compounds (e.g. [molivo’θici]>pencil case, [mavro’pinakas]>blackboard), 15 coordinate compounds (e.g. [alato’pipero]>salt and pepper, [vorioδiti’kos]>northwest) and 11 exocentric compounds (e.g. [kokkino’malis]>redhead, [ka’koγustos]>vulgar/tasteless). Hypotheses: According to the recent bibliography, agrammatic patients caused by stroke (StrAgr) and PPA-a patients have common performance in tasks which examine the morphosyntax (Thompson et al. 2013). So, PPA-a is expected to have the same deficits with StrAgr in naming compounds, given that compounding is a pure morphological procedure. Specifically, we expected compound effect, semantic transparency effect and lexical access through decomposition. Results: The error analysis showed differences in the performance of the two patients respect to the stage of the disease. Specifically, in the early stage substitution errors were occurred, supporting compound effect and a view of lexical access through decomposition. On the contrary, noncomposed semantic paraphasias and single words errors were occurred mainly at a later stage , indicating a more holistic access. Finally, the most errors were in subordinate compounds, whereas no effect of headedness and semantic transparency were found. Discussion: The results produce clear evidence that the stage of the PPA-a can affect the kind of the linguistic deficits. Specifically, in the initial stages, the linguistic deficits resemble with those of StrAgr patients with problems in the activation of the phonological form of the compound, whereas the morphological rules are intact. On the other hand, the naming competence is more impaired and distinctly different from other pathological populations at a later stage. Specifically, there are problems in the activation of both the phonological and the morphological compound forms. Finally, the increased difficulty with subordinate compounds will be correlated with the grammatical relations holding between the constituents.

As vicissitudes no uso do código da língua de indivíduos afásicos requerem do analista de discurso a apreensão dos sentidos de seus dizeres. O objetivo desta dissertação foi interpretar, à luz da análise de discurso de linha francesa, as reformulações que três sujeitos afásicos realizaram na narrativa oral, enfatizando os sentidos das hesitações, pausas e silêncios que esses sujeitos conferiram. O presente trabalho abordou o estudo da afasiologia, da neurolingüística, das narrativas e a interpretação destas no discurso dos sujeitos afásicos à luz da teoria de análise do discurso de linha francesa. A primeira ênfase foi dada ao estudo sobre o sistema nervoso central e suas áreas específicas para a linguagem, pois uma vez lesionadas, levam o sujeito a redescobrir uma maneira de se expressar e compreender o que lhe é dito. Uma outra questão foram os estudos da lingüística em relação à estruturação da língua e o funcionamento do curso da linguagem. Considerando conjuntamente o primeiro e segundo aspectos, foi possível elucidar-se um pouco mais, a respeito do funcionamento de linguagem em sujeitos afásicos / The vicissitudes on the use of language codes of aphasic subjects oblige the discourse analyst to understand the meanings of their speech. The objective of this study was to interpretate, according to French theory for discourse analysis, the reformulations that three aphasic subjects made on their oral narratives, emphasizing the meanings of hesitations, pauses and silences that these subjects attributed. Within this research, the author presented the study of aphasiology, neurolinguistics, narratives and their interpretations on the discourse of aphasic subjects, according to the French theory for discourse analysis. The first emphasis was the study of central nervous system and its language specific areas, which, once injured, oblige the subject to rediscover the ways to express and to understand whatever is said to him. Another aspect was the linguistic studies on language structure as well as on the performance of language flow. By joining the first and the second points of view, it was possible to elucidate a little more the language performance of aphasic subjects

abstract: Studies in Second Language Acquisition and Neurolinguistics have argued that adult learners when dealing with certain phonological features of L2, such as segmental and suprasegmental ones, face problems of articulatory placement (Esling, 2006; Abercrombie, 1967) and somatosensory stimulation (Guenther, Ghosh, & Tourville, 2006; Waldron, 2010). These studies have argued that adult phonological acquisition is a complex matter that needs to be informed by a specialized sensorimotor theory of speech acquisition. They further suggested that traditional pronunciation pedagogy needs to be enhanced by an approach to learning offering learners fundamental and practical sensorimotor tools to advance the quality of L2 speech acquisition. This foundational study designs a sensorimotor approach to pronunciation pedagogy and tests its effect on the L2 speech of five adult (late) learners of American English. Throughout an eight week classroom experiment, participants from different first language backgrounds received instruction on Articulatory Settings (Honickman, 1964) and the sensorimotor mechanism of speech acquisition (Waldron 2010; Guenther et al., 2006). In addition, they attended five adapted lessons of the Feldenkrais technique (Feldenkrais, 1972) designed to develop sensorimotor awareness of the vocal apparatus and improve the quality of L2 speech movement. I hypothesize that such sensorimotor learning triggers overall positive changes in the way L2 learners deal with speech articulators for L2 and that over time they develop better pronunciation. After approximately eight hours of intervention, analysis of results shows participants’ improvement in speech rate, degree of accentedness, and speaking confidence, but mixed changes in word intelligibility and vowel space area. Albeit not statistically significant (p >.05), these results suggest that such a sensorimotor approach to L2 phonological acquisition warrants further consideration and investigation for use in the L2 classroom. / Dissertation/Thesis / Doctoral Dissertation English 2015
