The Narrative Skills of Children with Specific Language Impairment and Typical Language

Phillips, Julie, Adams, Courtney, Morgan, Kelli, Rehm, Emilee, Stampler, Brianna, Proctor-Williams, Kerry 12 April 2017 (has links)
Purpose. The purpose of this research project was to compare the narrative content organization (macrostructure) of young children with specific language impairment (SLI) and those with typical language development (TL). While it is well-known that young children with SLI display poorer use of grammar (microstructure) than their TL language similar peers (Leaonard, 2014; Rice et al., 1998) less is known about their use of macrostructure. Thus, the research question was: What are the narrative skills of children with SLI as compared to their language similar peers with development TL? Based on research with older children (Gillam et al., 2016), it was hypothesized that children with SLI will have poorer narrative macrostructure of narratives than those with TL. Method. The experiment compared 6 children with SLI (mean age: 5 years, 2 months) and 8 language similar children with TL (mean age: 4 years, 8 months). Language equivalency was determined based on administration of the Clinical Evaluation of Language Fundamentals-Preschool-2 and the Rice/Wexler Test of Early Grammatical Impairment. As well, all the participants passed a hearing screening and performed in the average range on the Preschool Test of Nonverbal Intelligence. Researchers read two books, Gossie and Gossie & Gertie (Dunrea, 2002, 2002) to each child. After reading each book, the child retold the story while looking through the pictures as a guide, yielding 12 SLI samples and 16 TL samples. The stories were audio-recorded and transcribed using a consensus method of reliability. Researchers then coded the stories for presence and quality of the following components: Character, Setting, Initiating Event, Internal Response, Plan, Action/Attempt, and Consequence. Once coded, the components were then scored on a 3-point scale using Gillam et al. (2012) narrative development progressmonitoring tool. Results and Conclusions. First, outcomes of the two stories were compared using an ANOVA design with Story Components and Story as within group factors. Because Gossie & Gertie had one more character than Gertie, it naturally scored significantly higher on Characters. Otherwise, the stories did not reliably differ and were combined for further analysis. Next a mixed model ANOVA design with Story Components as a within group factor and Group as a between group faction was conducted. The results indicated no statistically significant main effects or interactions. The findings did not support the hypothesis, suggesting that the narrative skills of children with SLI are equivalent to their language similar peers with TL. It may be as children get older and their narratives become more complex, children with SLI begin to fall further behind yielding the differences reported in the literature. This project prompts future questions about narrative macrostructure skills of young age-matched children with SLI and TL and use of macrostructure skills in more complex stories.

Domain-specific modeling and verification language EDOLA

Zhang, Hehua 19 December 2009 (has links) (PDF)
With the widely use of software technique in everyday applications, the correctness of software becomes more and more important. Formal verification is an important method to improve the correctness of software. However, it mainly takes formal languages as its modeling languages, which are based on mathematical logic, automata or graph theory, hard for learning and domain description. That hinders the applications of formal verification in industry. This dissertation investigates the design and practice of domain modeling and verification language EDOLA, to possess all the features of the usability for domain description, reusability and automatic verification. It proposes a three-level design method with the domain knowledge level, the common module level and the verification support level. The main contributions are summarized as follows: 1. In the domain knowledge level, the extraction and representation methods of the domain knowledge on both job-shop scheduling and PLC control software are proposed. It defines domain-specific operators of the job-shop scheduling problem, timed Petri net, etc. for the job-shop scheduling description. It also defines the operators of the scan cycle pattern, the complete environment pattern and five kinds of verification requests for the PLC domain description. It presents the formal semantics of the defined domain-specific operators, for the further EDOLA definition and its automatic verification. 2. In the common module level, the method to define common operators is presented with real-time as an example for common knowledge. It proposes two kinds of basic time operators and four advanced ones, which help EDOLA to describe real-time features easily and make the reusability of EDOLA design among time-sensitive domains possible. 3. In the verification support level, it presents a properties-oriented abstraction strategy, which reduces the state space and exploring space during automatic verifi- cation. It then formulates the encoding rules from EDOLA to first-order logic, thus implements the verification of the models with infinite states, with the help of first-order logic automatic theorem provers. 4. A prototype of the PLC domain modeling and verification language: EDOLA-PLC are developed and its tools are implemented. The tools provide an EDOLA-PLC editor and a compiler with the functionalities like syntax checking, semantics checking and translation-based automatic verification. 5. A case study of the EDOLA-PLC language on a dock fire-fighting control system is presented. It indicates that EDOLA-PLC is easy to describe both the PLC domain knowledge and the properties to be verified; is easy to describe the common knowledge: real-time and can be verified automatically. The results show that the abstraction strategy adopted in the verification support level of EDOLA-PLC improves the efficiency of automatic verification.

Developing and Testing Pervasive Computing Applications: A Tool-Based Methodology

Bruneau, Julien 16 May 2012 (has links) (PDF)
Malgré des progrès récents, développer une application d'informatique ubiquitaire reste un défi à cause d'un manque de canevas conceptuels et d'outils aidant au développement. Ce défi implique de prendre en charge des objets communicants hétérogènes, de surmonter la complexité des technologies de systèmes distribués, de définir l'architecture d'une application, et d'encoder cela dans un programme. De plus, tester des applications d'informatique ubiquitaire est problématique car cela implique d'acquérir, de tester et d'interfacer une variété d'entités logicielles et matérielles. Ce procédé peut rapidement devenir coûteux en argent et en temps lorsque l'environnement ciblé implique de nombreuses entités. Cette thèse propose une méthodologie outillée pour dévelop- per et tester des applications d'informatique ubiquitaire. Notre méthodologie fournit tout d'abord le langage de conception DiaSpec. Ce langage permet de définir une taxonomie d'entités spécifiques à un domaine applicatif, s'abstrayant ainsi de leur hétérogénéité. Ce langage inclut également une couche permettant de définir l'architecture d'une application. Notre suite outillée fournit un compilateur qui, à partir de descriptions DiaSpec, génère un canevas de programmation guidant les phases d'implémentation et de test. Afin d'aider à la phase de test, nous proposons une approche de simulation et un outil intégré dans notre méthodologie outillée : l'outil DiaSim. Notre approche utilise le support de test généré par DiaSpec pour tester les applications de manière transparente dans un environnement physique simulé. La simulation d'une application est rendue graphiquement dans un outil de visualisation 2D. Nous avons combiné DiaSim avec un langage dédié permet- tant de décrire les phénomènes physiques en tant qu'équations différentielles, permettant des simulations réalistes. DiaSim a été utilisé pour simuler des applications dans des domaines applicatifs variés. Notre approche de simulation a également été appliquée à un système avionique, démontrant la généralité de notre approche de simulation.

Feld - fällt - fehlt : Untersuchungen zur Phonologie-Morphosyntax-Schnittstelle bei Kindern und Erwachsenen

Ott, Susan January 2012 (has links)
Neben der Frequenz eines cues ist es dessen Zuverlässigkeit, die Kindern hilft, die an sie gerichtete Sprache zu segmentieren, Worteinheiten zu erkennen sowie diese syntaktisch zu kategorisieren. Im Deutschen weist die Subsilbe „Langvokal+Konsonant+/t/“ (z.B. in fehlt, wohnt) zuverlässig auf eine -t-flektierte Verbform hin. Die in kindgerichteter Sprache höher frequente Subsilbe „Kurzvokal+Konsonant+/t/“ (z.B. in Feld, Hemd, fällt, rund) gibt hingegen keinen derartig eindeutigen Hinweis. Es wurde der Frage nachgegangen, inwiefern diese unterschiedlichen Zuverlässigkeiten und Frequenzen der Subsilben auf die Nomen-, Verb- und Verbflexionsverarbeitung einwirken. Drei Altersgruppen wurden untersucht: achtzehn Monate alte Kinder, drei- bis fünfjährige sprachunauffällige und -auffällige Kinder sowie erwachsene Sprecher. Einflüsse der unterschiedlichen Zuverlässigkeiten und Frequenzen der ausgewählten Subsilben konnten für alle Probandengruppen gefunden werden. Die Subsilbe stellt damit eine linguistische Größe dar, die in der frühen Sprachwahrnehmung als cue dienen sowie die Sprachverarbeitung Erwachsener lenken kann und auch für die Sprachdiagnostik und -therapie sprachauffälliger Kinder berücksichtigt werden sollte. / Frequency and reliability have an impact on children’s reliance on cues for the segmentation and syntactic categorization of words. In German, the subsyllable “long vowel+consonant+/t/” reliably indicates that a word containing this type of subsyllable is an inflected verb form, e.g. “fehlt” (to lack, 3rd pers. sing.) or “wohnt” (to live, 3rd pers. sing.) In contrast, the more frequent subsyllable “short vowel+consonant+/t/” is not a reliable cue to word class as it occurs not only in inflected verb forms but in monomorphemic nouns and adjectives as well, e.g. “fällt” (to fall, 3rd pers. sing.), “Hemd” (shirt), “Feld” (field) or “rund” (round). This study addresses the question to what extent the different cue properties of subsyllables (i.e. reliability and frequency) have an impact on the processing of nouns, verbs and verb inflection. Participants of three different age groups were recruited: eighteen-month-old children, three- to five-year-old children with typical and atypical language acquisition and adults. Impacts of the different subsyllabic reliabilities and frequencies were found for all groups. This indicates that the subsyllable is a linguistic unit that provides relevant cues for early language acquisition and for language processing in adults. Therefore, it should also be considered for assessment and treatment of children with atypical language acquisition.

Feature Oriented Domain Specific Language For Dependency Injection In Dynamic Software Product Lines

Dayibas, Orcun 01 September 2009 (has links) (PDF)
Base commonality of the Software Product Line (SPL) Engineering processes is to analyze commonality and variability of the product family though, SPLE defines many various processes in different abstraction levels. In this thesis, a new approach to configure (according to requirements) components as building blocks of the architecture is proposed. The main objective of this approach is to support domain design and application design processes in SPL context. Configuring the products is made into a semi-automatic operation by defining a Domain Specific Language (DSL) which is built on top of domain and feature-component binding model notions. In order to accomplish this goal, dependencies of the components are extracted from the software by using the dependency injection method and these dependencies are made definable in CASE tools which are developed in this work.

Sričiai orientuotos informacinės sistemos kūrimo metodikos tyrimas ir taikymas / Research of DSL for information system development

Strakšys, Justinas 04 March 2009 (has links)
Viena iš naujausių sistemų kūrimo metodikų – sričiai orientuotas modeliavimas (angl. domain specific modeling). Ji paremta sričiai orientuotos kalbos kūrimu ir jos panaudojimu sistemos kūrimui. Ši metodika leidžia sistemos kūrimui naudoti sąvokas, artimas probleminei sričiai, kas padidina abstrakcijos lygi projektavimo metu. Srities sąvokos aptariamos ir įvardinamos kartu su ekspertais ar paprastais darbuotojais, dirbančiais analizuojamoje srityje, ir nebūtinai išmanančiais sistemų kūrimo metodus. Ši metodika leidžia sistemos projektuotojui lengviau susikalbėti su užsakovais, nes modeliuose figūruojančios sąvokos yra užsakovui suprantamos ir aiškios. / Domain Specific Modeling is a software engineering methodology for designing and developing information systems. It involves systematic use of a graphical domain specific language (DSL) to represent the various facets of a system. DSM languages tend to support higher-level abstractions than general purpose modeling languages, so they require less effort and fewer low-level details to specify a given system which is very important nowadays, when the functionality of information system must be maximized with minimum development time and cost. This paper compares usage of DSL for information system development with other two, most often used methodologies for this purpose: MDA and usage of UML. It gives basic advantages and disadvantages of DSL and DSM usage, describes differences of DSL (DSM), UML and MDA. This paper also describes usage of DSM methodology (creating DSL and using it for software development) for creating information system. It covers main steps of creation process’s: describing the domain concepts, describing the artifacts that are planning for the DSL, building domain model, building the designer for DSL, building the artifact generator, implementing validations and constraints, testing and deploying the DSL.

Klassrummets semiotiska resurser : en språkdidaktisk studie av skolämnena hem- och konsumentkunskap, biologi och kemi / The Semiotic Resources of the Classroom : An Applied Linguistics Perspective on the School subjects Home and Consumer Studies, Biology and Chemistry

Hipkiss, Anna Maria January 2014 (has links)
This thesis focuses on how different semiotic resources, such as spoken and written texts, artefacts and activities interact with classroom design and classroom communication in three school subjects in Swedish secondary school: Home and Consumer Studies, Biology and Chemistry. The research process has been concerned with the affordances that are created through different semiotic resources in classroom design and in classroom communication in the three school subjects, focusing on academic language and student participation. The study used an ethnographic approach, employing multiple methods for material production and analysis. Video and audio recordings formed the foundation for analysis. Material production also includes field notes, photographs and interviews with teachers and students. The research draws on sociocultural theory using a three-legged theoretical framework based in sociocultural theory. Basil Bernstein’s sociological theories were used as an overarching theory for understanding the results. The sociosemiotic theories of Systemic Functional Linguistics (SFL) and Social Semiotic Multimodality were adopted for analyzing classroom design and classroom communication. This study shows that classroom design and classroom communication are tied together. Classroom design presents affordances for a subject’s ideational and interpersonal meaning. These affordances are reproduced in classroom communication. In classrooms with subject-focused design, classroom communication is school-focused. Learning is segmented without connection between school subjects or other contexts. In one classroom, designed to create relevance for both school and everyday knowledge, communication is both school-focused and also creates relevance for students’ use of the contents in other contexts. Learning in this classroom is cumulative and students’ participation and meaning-making is integrated in teaching and design. This study also shows how different semiotic resources influence teacher’s and students’ linguistic choices. Vertical discourse, i.e. abstract and distant academic language, is realised in written texts such as text books and whiteboard texts. Few other artefacts introduce and encourage participants’ vertical discourse. Teacher and student communication realises mainly horizontal discourse, i.e. context embedded everyday language. Classroom communication provides few opportunities for students to appropriate academic language through semantic waves, as academic language is only unpacked into everyday language and not repacked into academic language.

An Intervention Approach to Target Vocabulary Development in Te Reo Maori in Maori Immersion Settings

Gallagher, Kerrie Louise January 2008 (has links)
The aim of this study was to investigate the effectiveness of a storybook retell technique to facilitate vocabulary acquisition in children educated in Māori immersion class settings. A second aim of the study was to explore the cultural responsiveness and pedagogical appropriateness of the intervention approach and the importance of relationship building (whakawhanaungatanga) to successful interventions. Nine children participated in the study. These children (aged between 5 and 8 years) were recruited from two Kura Kaupapa Māori settings in differing urban areas in New Zealand. The children entered the study on a rolling basis in groups of three. The first three participants to enter the study were recruited from the one classroom on the basis of their demonstrating specific language impairment (SLI). The second group of three participants attended a different classroom and these participants were recruited into the study as a result of identified delayed reading development (RD). The third group of three participants from a third classroom was selected as the participants exhibited typical spoken and written language development (TD). The intervention technique utilized in this study adopted a structured approach to teaching the meaning of pre selected vocabulary items that were embedded in class story books. Three different books were selected and each book was read by the teacher to the whole class three times during a one week period. The target vocabulary was highlighted each time it occurred in the story through the following techniques: an adult definition was given for the word, an antonym or synonym was given, and the meaning was acted out by the teacher or the picture detailing the meaning of the word in the book was highlighted. A single subject research design using pre-intervention, intervention and post intervention assessment probes for the target vocabulary items was employed to examine the effectiveness of the intervention in teaching the children the targeted vocabulary. Teacher interviews were also carried out to assess the appropriateness of the intervention in relation to the philosophy of the Kura Kaupapa and its pedagogical appropriateness and cultural responsiveness. The results suggested that the children in all three groups (SLI, RD and TD) made moderate gains in the acquisition of the target vocabulary supporting the hypothesis that targeting vocabulary in story book retelling at a whole class level will lead to acquisition of the vocabulary by the participants' exposed to the intervention. However, using a Two Standard Deviation method to evaluate the significance of each participant's change, the gains made for the RD and SLI participants were not significant. The TD participants did demonstrate a significant difference in the number of words correct. The teachers of the participants involved in the study reported positively on the effectiveness and appropriateness of the intervention for inclusion within the Kura Kaupapa and classroom programme. In particular, teachers' reported that as the intervention included each child in the class (as opposed to a withdrawal intervention model) the intervention was more appropriate for the philosophy of the Kura Kaupapa. The teachers' also reported the effectiveness of the intervention for the development of collaboration and relationship building between the teacher and researcher (a speech-language therapist. The data showed that the intervention investigated in this study was culturally responsive and pedagogically appropriate. It could be included as a component of the class programme as it was responsive to the philosophy of the Kura Kaupapa. The participants' did make moderate gains in the acquisition of the vocabulary (although not at a level to be considered significant for children with delayed development). Further research is necessary to explore the effectiveness of what may potentially be a useful intervention to enhance vocabulary development for children in Kura Kaupapa.

Rhythmic sensitivity and developmental language disorder in children

Richards, Susan Mary January 2017 (has links)
Children with Developmental Language Disorder (DLD) have difficulties in acquiring language in the absence of other neurodevelopmental issues (e.g. autism, hearing impairment) and despite growing up in an adequate language-learning environment. Previous characterisations of DLD have focused on grammatical processing, phonological memory or rapid auditory processing. This thesis approaches the language-learning difficulties of children with DLD from a novel perspective by considering the potential contribution made by differing levels of sensitivity to the rhythmic properties of language. Children with DLD have been shown to have reduced sensitivity to some of the acoustic cues present in speech which are thought to be important for rhythmic perception. Since rhythm forms the basis of language processing in early development, poorer sensitivity to language rhythm may result in later language problems. To investigate whether children with DLD demonstrate difficulties in processing language rhythm, this thesis explores five areas of language processing which could be affected by poor rhythmic sensitivity: locating word-boundaries, processing novel words, storing lexical stress patterns, representing sentence level structures and the integration of rhythm and syntax. As part of the investigation, measures were also taken of acoustic threshold sensitivity to see whether task performance related to acoustic sensitivity. A parallel strand of the study investigated whether provision of an entraining rhythm prior to task stimuli could support task performance. Three groups of children participated in the study: children with DLD, age-matched TD children (AMC) and younger, language-matched TD children (YLC). The results indicate that rhythmic manipulation of language stimuli affects task responses across the five language areas under investigation. The findings are then discussed in terms of the contribution made to our understanding of the role of rhythm in language and language disorder.

[en] LANGUAGE DIFFICULTIES OF CHILDREN WITH LEARNING PROBLEMS: SOME RELATIONS WITH SLI AND THE DEVELOPMENT OF THEORY OF MIND / [pt] PROBLEMAS DE LINGUAGEM EM CRIANÇAS COM DIFICULDADES DE APRENDIZAGEM (DAP): RELAÇÕES COM O DÉFICIT ESPECÍFICO DA LINGUAGEM (DEL) E O DESENVOLVIMENTO DA TEORIA DA MENTE

WANDERSON FERREIRA BOMFIM 17 March 2009 (has links)
[pt] Esta dissertação tem como objetivo principal avaliar o desempenho linguístico de crianças com problemas de aprendizagem, de modo a verificar em que medida essas dificuldades equivalem às características do quadro do DEL (Déficit Específico da Linguagem). Pretende-se ainda avaliar o desempenho de crianças com problemas de aprendizagem por meio de uma tarefa clássica de crenças falsas para caracterização do desenvolvimento da Teoria da Mente (ToM), tendo em vista que esse desenvolvimento tem sido apontado como comprometido diante de um déficit linguístico. Este trabalho também visou a ampliar a amostra de crianças sem queixas de linguagem submetidas à  avaliação por meio do MABILIN (Módulos de Avaliação de Habilidades Linguísticas), em desenvolvimento no LAPAL (Laboratório de Psicolinguí­stica e Aquisição da Linguagem - PUC-RIO), na padronização do teste, de modo a obter-se uma caracterização do desenvolvimento linguístico no Português do Brasil (PB), que possa ser tomada como referência na avaliação de problemas de linguagem e, particularmente, do DEL. Foram avaliadas 30 crianças de cerca de 6 anos de idade, com e sem queixas de aprendizagem, de nível sócio-econômico baixo na rede de ensino público da Secretaria de Estado de Educação do Distrito Federal. Os resultados obtidos mostram que o desempenho de crianças com queixas de aprendizagem foi, de maneira geral, inferior ao das crianças sem queixas de aprendizagem. Tanto em tarefas de compreensão de sentenças simples ativas, passivas reversíveis/irreversíveis, coordenadas, relativas e interrogativas QU, como em tarefas cuja compreensão se faz dependente de concordância de gênero e número, a diferença entre as crianças com queixas de aprendizagem e as crianças sem queixas mostrou-se significativa. Os resultados indicam dificuldades de ordem linguística compartilhadas com o DEL, ainda que o efeito de grupo, independentemente das variáveis linguísticas manipuladas, apontando para um pior desempenho do grupo com queixas de aprendizagem, sugira dificuldades de outra ordem interferindo no desempenho linguístico. O resultado no teste de ToM revela que o grupo de crianças com queixas de aprendizagem, mais do que grupo controle, tem dificuldade em prever a ação de um personagem a partir da atribuição de uma crença falsa a este. Dificuldades no uso de pistas para a solução de tarefas linguísticas e na elaboração de inferências dependentes de ToM pode, portanto, comprometer o desempenho escolar desse grupo. / [en] The primary aim of this dissertation is to evaluate the linguistic performance of 30 children with learning impairment in order to verify the extent to which these difficulties are equivalent to those that characterize the performance of SLI (Specific Language Impairment) children. The performance of children with learning impairment was also evaluated by means of a classic false belief task intended to assess their development as far as Theory of Mind is concerned, since this development has been pointed to be compromised in face of linguistic impairment. Moreover, this research aimed to enlarge the sample of children without language impairment whose linguistic performance is assessed by means of a set of tests (Modules for the Evaluation on Linguistic Abilities), that has been developed in LAPAL (Laboratório de Psicolinguí­stica e Aquisição de Linguagem - PUC-RIO), intended to identify those aspects of language that are particularly affected in SLI Brazilian Portuguese speaking children. The performance of 30 children with and without learning impairment, of low economical background and age average by 6 years old was evaluated at a public school in the outskirts of Brasilia, Federal District, Brazil. The results show that the performance of children with learning impairment was, generally, lower in comparison with children without learning impairment. The performance in comprehension tasks focusing on simple active and passive sentences, reversible/irreversible, coordinated, relative clauses, WH interrogatives, and in tasks focusing on the processing of gender and number agreement was significantly different between children with and without learning impairment. The results indicate linguistics difficulties shared with Specific Language Impairment in the learning impaired group, even though the effect of group, independently of the linguistic variable manipulated, suggests that difficulties of a different order might affect their linguistic performance. The result of the test of false belief task shows that the group with learning impairment, more than the control group, has difficulty in foreseeing the action of a character from a false belief attribution. Difficulties in using clues in the solution of the linguistic tasks and in the elaboration of dependent inferences of ToM can therefore impair the school performance of this group.
