Aspects of Passives in Capeverdean (Santiago’s variety)

The present dissertation intends to study passives in Capeverdean. I argue that Capeverdean have eventive passives with specific morphology, postverbal morphemes, -du and -da, which affix to the verb to form passives and interact with the TMA morphemes available in the language in the same way as in the active voice. I also show that Capeverdean only allows short passives. However, this study demonstrates that the by-phrase, although not expressed phonologically, is implicit and can be tracked through instrumentals and Agent-oriented adverbs. In order to account for this specific property of Capeverdean passives, I assume the existence of a Voice head which introduces the external argument in all finite sentences in Capeverdean, except in unaccusatives, following proposals from Marantz (1984), Kratzer (1996), Sailor & Ahn (2010), Pratas (2014). I also assume that this Voice head is subject to a Doubly Filled Comp Filter, similar to what is proposed in Koopman (1997), which determines that either heads or specifiers can be overt, never both. In the case of passives, I propose that external argument is in Spec,Voice and the passive morphology is lexicalized in Voice0 and that while Spec,Voice is silent, Voice0 is not. This configuration can be explained if it is assumed, following Costa & Martins (2004), that in Capeverdean passives Voice0 is a strong functional head, thus requiring visibility at PF. This restriction, combined with the Doubly Filled Comp filter, imposes that Spec,Voice is silent.

A neuronal gamma oscillatory signature during morphological unification in the left occipitotemporal junction.

Morphology is the aspect of language concerned with the internal structure of words. In the past decades, a large body of masked priming (behavioral and neuroimaging) data has suggested that the visual word recognition system automatically decomposes any morphologically complex word into a stem and its constituent morphemes. Yet the reliance of morphology on other reading processes (e.g., orthography and semantics), as well as its underlying neuronal mechanisms are yet to be determined. In the current magnetoencephalography study, we addressed morphology from the perspective of the unification framework, that is, by applying the Hold/Release paradigm, morphological unification was simulated via the assembly of internal morphemic units into a whole word. Trials representing real words were divided into words with a transparent (true) or a nontransparent (pseudo) morphological relationship. Morphological unification of truly suffixed words was faster and more accurate and additionally enhanced induced oscillations in the narrow gamma band (60-85 Hz, 260-440 ms) in the left posterior occipitotemporal junction. This neural signature could not be explained by a mere automatic lexical processing (i.e., stem perception), but more likely it related to a semantic access step during the morphological unification process. By demonstrating the validity of unification at the morphological level, this study contributes to the vast empirical evidence on unification across other language processes. Furthermore, we point out that morphological unification relies on the retrieval of lexical semantic associations via induced gamma band oscillations in a cerebral hub region for visual word form processing.

Reading Development During Elementary School Years. Evidence from Eye Movements

The present dissertation examined reading development during elementary school years by means of eye movement tracking. Three different but related issues in this field were assessed. First of all, the development of parafoveal processing skills in reading was investigated. Second, it was assessed whether and to what extent sublexical units such as syllables and morphemes are used in processing Finnish words and whether the use of these sublexical units changes as a function of reading proficiency. Finally, the developmental trend in the speed of visual information extraction during reading was examined. With regard to parafoveal processing skills, it was shown that 2nd graders extract letter identity information approx. 5 characters to the right of fixation, 4th graders approx. 7 characters to the right of fixation, and 6th graders and adults approx. 9 characters to the right of fixation. Furthermore, it was shown that all age groups extract more parafoveal information within compound words than across adjectivenoun pairs of similar length. In compounds, parafoveal word information can be extracted in parallel with foveal word information, if the compound in question is of high frequency. With regard to the use of sublexical units in Finnish word processing, it was shown that less proficient 2nd graders use both syllables and morphemes in the course of lexical access. More proficient 2nd graders as well as older readers seem to process words more holistically. Finally, it was shown that 60 ms is enough for 4th graders and adults to extract visual information from both 4-letter and 8-letter words, whereas 2nd graders clearly needed more than 60 ms to extract all information from 8- letter words for processing to proceed smoothly. The present dissertation demonstrates that Finnish 2nd graders develop their reading skills rapidly and are already at an adult level in some aspects of reading. This is not to say that there are no differences between less proficient (e.g., 2nd graders) and more proficient readers (e.g., adults) but in some respects it seems that the visual system used in extracting information from the text is matured by the 2nd grade. Furthermore, the present dissertation demonstrates that the allocation of attention in reading depends much on textual properties such as word frequency and whether words are spatially unified (as in compounds) or not. This flexibility of the attentional system naturally needs to be captured in word processing models. Finally, individual differences within age groups are quite substantial but it seems that by the end of the 2nd grade practically all Finnish children have reached a reasonable level of reading proficiency.

Esiopetuskirjojen harjoitukset kielellisen tietoisuuden kehittäjinä

Tutkimus oli kasvatustieteellinen varhaiskasvatuksen alan tutkimus, jossa hyödynnettiin kielitieteellistä käsitteistöä. Tutkimuksen kohteena olivat esiopetuskirjojen kielellisen tietoisuuden harjoitukset. Aineistona oli 12 esiopetuksen harjoituskirjaa ja opettajan opasta. Kirjoissa oli yhteensä yli 2000 sivua ja yli 1300 harjoitusta. Tarkemmassa analyysissä olleiden harjoitusten määrä oli noin 460. Analyysimenetelmänä käytettiin sisällönanalyysiä, jonka avulla tutkittiin, millaisia kielellisen tietoisuuden harjoituksia esiopetuskirjoissa oli ja miten harjoitukset etenivät. Kielellisen tietoisuuden harjoitukset luokiteltiin fonologisen, morfologisen ja syntaktisen tietoisuuden harjoituksiin. Fonologinen tietoisuus käsitettiin lapsen kyvyksi havaita ja käsitellä kielen äännerakennetta. Morfologisella tietoisuudella tarkoitettiin kykyä havaita ja käsitellä kielen morfeemeja eli pienimpiä merkityksellisiä osia. Syntaktisella tietoisuudella tarkoitettiin lapsen tietoisuutta siitä, miten lauseet rakentuvat. Olennaisiksi piirteiksi fonologisen tietoisuuden harjoituksissa identifioituivat harjoitusten edellyttämä tai harjoittama tietoisuuden taso, harjoitusten kohteena olevien lingvististen yksiköiden taso ja harjoitustyyppi sekä morfologisen ja syntaktisen tietoisuuden harjoituksissa tietoisuuden taso ja harjoitustyyppi. Tutkimuksessa luotiin aikaisempien tutkimusten pohjalta mallit siitä, miten eri harjoitukset etenisivät optimaalisesti lapsen kielellisen tietoisuuden kehittymisen kannalta. Eri harjoituskirjojen harjoitusten etenemistä verrattiin näihin malleihin. Fonologisen tietoisuuden harjoituksista voitiin tunnistaa viisi päätyyppiä, joista useat jakautuivat vielä alatyypeiksi. Harjoitusten alatyypit ilmaisivat yleensä harjoituksissa käytettävän kognitiivisen operaation – käytettiinkö harjoituksessa tunnistamista, yhdistämistä vai osiin jakamista. Tämä samoin kuin harjoituksessa käytetty lingvistinen yksikkö (sana, loppusointu, tavu tai äänne) ja tietoisuuden taso olivat yhteydessä harjoituksen vaikeuteen. Tutkimuksissa ja interventioissa esiopetusikäisilläkin käytettyjä muunteluharjoituksia, joissa sanasta tai tavusta poistetaan osa, siihen lisätään osa tai osaa siirretään, harjoituskirjoissa ei ollut. Morfologisen tietoisuuden harjoitukset kohdistuivat yhdyssanoihin, taivutuspäätteisiin tai johdoksiin. Syntaktisen tietoisuuden harjoituksista identifioitui yhdentoista harjoituslajin alatyypin kautta kuusi päätyyppiä. Tutkimusta voidaan hyödyntää esiopetuskirjojen arvioinnissa ja laatimisessa sekä varhaiskasvatus- ja esiopetuspedagogiikassa.

Morphonotactic and phonotactic processing in German-speaking adults

Based on the theoretical framework of Dressler and Dziubalska-Kołaczyk (2006a,b), the Strong Morphonotactic Hypothesis will be tested. It assumes that phonotactics helps in decomposition of words into morphemes: if a certain sequence occurs only or only by default over a morpheme boundary and is thus a prototypical morphonotactic sequence, it should be processed faster and more accurately than a purely phonotactic sequence. Studies on typical and atypical first language acquisition in English, Lithuanian and Polish have shown significant differences between the acquisition of morphonotactic and phonotactic consonant clusters: Morphonotactic clusters are acquired earlier and faster by typically developing children, but are more problematic for children with Specific Language Impairment. However, results on acquisition are less clear for German. The focus of this contribution is whether and how German-speaking adults differentiate between morphonotactic and phonotactic consonant clusters and vowel-consonant sequences in visual word recognition. It investigates whether sub-lexical letter sequences are found faster when the target sequence is separated from the word stem by a morphological boundary than when it is a part of a morphological root. An additional factor that is addressed concerns the position of the target cluster in the word. Due to the bathtub effect, sequences in peripheral positions in a word are more salient and thus facilitate processing more than word-internal positions. Moreover, for adults the primacy effect most favors word-initial position (whereas for young children the recency effect most favors word- final position). Our study discusses effects of phonotactic vs. morphonotactic cluster status and of position within the word.

Le Réel dans le texte : lecture et interprétation de la figure de Bartleby le scribe

La nouvelle « Bartleby The Scrivener. A Story of Wall-Street » pose des questions de lecture et d’interprétation littéraire. Grâce à des approches ayant le discours pour objet ou moyen de connaissance (rhétorique, étymologie, psychanalyse, pragmatique) de même qu’aux écrits de Herman Melville, il s’agit de cerner ce que représente Bartleby, qualifié d’« unaccountable » (inexplicable). Ce mot organise l’étude. Entier ou décomposé en morphèmes, dans une première partie, il met en évidence des univers de sens où Bartleby se montre marginal et court-circuite les systèmes : l’univers du langage (« unaccountable » : inénarrable), celui de la loi (« count » : chef d’accusation) et celui des chiffres (« account, count » : compte, compter). Une seconde partie rattache les pistes de lecture implicites ainsi dégagées aux thématiques de l’« inexplicable », explicites dans le texte, permettant une interprétation touchant l’univers des lettres, leur pérennité et leur circulation par le biais de la lecture et de l’interprétation.

Effets de la croissance des capacités respiratoires sur la longueur des énoncés et sur la diversité lexicale

Brown (1973) a proposé la « longueur moyenne des énoncés » (LME) comme indice standard du développement langagier. La LME se calcule selon le nombre moyen de morphèmes dans 100 énoncés de parole spontanée. L’hypothèse sous-jacente à cet indice est que la complexité syntaxique croît avec le nombre de morphèmes dans les énoncés. Selon Brown, l’indice permet d’estimer le développement d’une « compétence grammaticale » jusqu’à environ quatre morphèmes. Certains auteurs ont toutefois critiqué le manque de fiabilité de la LME et la limite de quatre morphèmes. Des rapports démontrent des variations de la LME avec l’âge, ce qui suggère que des facteurs comme la croissance des capacités respiratoires peuvent influencer l’indice de Brown. La présente étude fait état de ces problèmes et examine comment la LME et certaines mesures de diversité lexicale varient selon le développement des capacités respiratoires. On a calculé la LME et la diversité lexicale dans la parole spontanée de 50 locuteurs mâles âgés de 5 à 27 ans. On a également mesuré, au moyen d’un pneumotachographe, la capacité vitale (CV) des locuteurs. Les résultats démontrent que la LME et des mesures de diversité lexicale corrèlent fortement avec la croissance de la CV. Ainsi, la croissance des fonctions respiratoires contraint le développement morphosyntaxique et lexical. Notre discussion fait valoir la nécessité de réévaluer l’indice de la LME et la conception « linguistique » du développement langagier comme une compétence mentale qui émerge séparément de la croissance des structures de performance.

Exclamatives en -tu, donc et assez en français québécois : types et sous-types

Nous soutenons dans ce mémoire qu'il existe, en français québécois, deux sous-types de constructions exclamatives. Située dans un cadre théorique qui participe à la fois de la philosophie du langage (la théorie des actes de langage, Austin, 1962; Searle 1969, Searle, 1979; Searle et Vanderveken 1985) et de la linguistique (la théorie des types de phrase, Sadock et Zwicky, 1985; Reis, 1999), notre analyse porte sur un ensemble de constructions exclamatives en apparence synonymes qui impliquent respectivement les morphèmes -tu, donc et assez (1). (1) Elle est-tu/donc/assez belle! Nous démontrons que si ces exclamatives satisfont aux critères d'identification des constructions exclamatives donnés par Zanuttini et Portner (2003) (factivité, évaluativité/implicature scalaire, expressivité/orientation vers le locuteur et incompatibilité avec les paires de question/réponse), les actes de langage exclamatifs servis par les exclamatives en -tu/donc n'ont pas les mêmes conditions de félicité que les actes de langage exclamatifs servis par les exclamatives en assez. En effet, les exclamatives en -tu/donc imposent une contrainte sur leur contexte d'énonciation par rapport à la position épistémique de l'interlocuteur, lequel doit être en mesure de corroborer le jugement exprimé par le locuteur au moyen de l'exclamative. Les exclamatives en assez n'imposent pas de telle contrainte. Nous démontrons que cette distinction pragmatique peut être corrélée avec des distinctions sémantiques et syntaxiques et concluons qu'il existe bien deux sous-types de constructions exclamatives en français québécois. En ce sens, notre recherche ouvre de nouvelles perspectives empiriques et théoriques pour la description et l'analyse de la grammaire des actes de langage exclamatifs.

Development Of A Pos Tagger For Malayalam-An Experience

A Parts of Speech tagger for Malayalam which uses a stochastic approach has been proposed. The tagger makes use of word frequencies and bigram statistics from a corpus. The morphological analyzer is used to generate a tagged corpus due to the unavailability of an annotated corpus in Malayalam. Although the experiments have been performed on a very small corpus, the results have shown that the statistical approach works well with a highly agglutinative language like Malayalam

Complexity of Human Language Comprehension

The goal of this article is to reveal the computational structure of modern principle-and-parameter (Chomskian) linguistic theories: what computational problems do these informal theories pose, and what is the underlying structure of those computations? To do this, I analyze the computational complexity of human language comprehension: what linguistic representation is assigned to a given sound? This problem is factored into smaller, interrelated (but independently statable) problems. For example, in order to understand a given sound, the listener must assign a phonetic form to the sound; determine the morphemes that compose the words in the sound; and calculate the linguistic antecedent of every pronoun in the utterance. I prove that these and other subproblems are all NP-hard, and that language comprehension is itself PSPACE-hard.

Como os nossos filhos aprendem a falar? : percurso de aquisição da Língua Portuguesa falada no Brasil

Esta investigação teve como objetivo descrever o percurso de aquisição da Língua Portuguesa falada no Brasil. Como base teórica, adotamos um referencial múltiplo, com abordagem das teorias behaviorista, inatista, cognitivista piagetiana, sócio-interacionista e emergentista, no intuito de buscar em cada uma delas as contribuições que nos auxiliassem no estudo da aquisição da linguagem. Trata-se de um estudo longitudinal em que registramos quinzenalmente em áudio o desenvolvimento linguístico de duas crianças brasileiras, desde a idade de 1;00 até 5;00. Os dados obtidos receberam transcrição fonética e/ou ortográfica e foram analisados nos aspectos fonológico, morfológico e sintático. Na área da fonologia, apresentamos o percurso de aquisição dos fonemas, os fonemas de difícil pronunciação e as estratégias de reparo usadas pelas crianças. Na morfologia, descrevemos o processo de aprendizagem dos morfemas flexivos nominais e verbais. Na sintaxe, apresentamos o caminho percorrido pelas crianças na construção das orações simples e dos diversos tipos de orações compostas. De modo geral, observamos um processo de aprendizagem lenta e gradual, em que provavelmente interatuam fatores de ordem biológica, cognitiva, social e linguística, marcado por elevações e regressões indicativas de uma auto-regulação do sistema-que-aprende.

On the nature and cause of Specific Language Impairment: a view from sentence processing and infant research

This paper addresses the nature and cause of Specific Language Impairment (SLI) by reviewing recent research in sentence processing of children with SLI compared to typically developing (TD) children and research in infant speech perception. These studies have revealed that children with SLI are sensitive to syntactic, semantic, and real-world information, but do not show sensitivity to grammatical morphemes with low phonetic saliency, and they show longer reaction times than age-matched controls. TD children from the age of 4 show trace reactivation, but some children with SLI fail to show this effect, which resembles the pattern of adults and TD children with low working memory. Finally, findings from the German Language Development (GLAD) Project have revealed that a group of children at risk for SLI had a history of an auditory delay and impaired processing of prosodic information in the first months of their life, which is not detectable later in life. Although this is a single project that needs to be replicated with a larger group of children, it provides preliminary support for accounts of SLI which make an explicit link between an early deficit in the processing of phonology and later language deficits, and the Computational Complexity Hypothesis that argues that the language deficit in children with SLI lies in difficulties integrating different types of information at the interfaces.

Production and processing asymmetries in the acquisition of tense morphology by sequential bilingual children

This study investigates the production and on-line processing of English tense morphemes by sequential bilingual (L2) Turkish-speaking children with more than three years of exposure to English. Thirty nine 6-9-year-old L2 children and 28 typically developing age-matched monolingual (L1) children were administered the production component for third person –s and past tense of the Test for Early Grammatical Impairment (Rice & Wexler, 1996) and participated in an on-line word-monitoring task involving grammatical and ungrammatical sentences with presence/omission of tense (third person –s, past tense -ed) and non-tense (progressive –ing, possessive ‘s) morphemes. The L2 children’s performance on the on-line task was compared to that of children with Specific Language Impairment (SLI) in Montgomery & Leonard (1998, 2006) to ascertain similarities and differences between the two populations. Results showed that the L2 children were sensitive to the ungrammaticality induced by the omission of tense morphemes, despite variable production. This reinforces the claim about intact underlying syntactic representations in child L2 acquisition despite non target-like production (Haznedar & Schwartz, 1997).
