Two general language measures were collected from the children: a standardized receptive vocabulary measure (Test de Vocabulario en Imágenes, TVIP), and a parental report of speech and language problems. In addition, morphosyntactic measures of language development were obtained using both a story retelling and an elicitation task. Developmental language measures such as number of T-units (NU-TU), mean length of T-units (MLTU), subordination index (SUB-I), and grammatical errors per T-unit (GRE-TU) were derived from the narratives. Percentages of correct use of direct and indirect object pronouns, reflexive pronouns, definite articles, indefinite articles, adjectives and plurals were obtained from an elicitation task that was specifically designed for this study. Counts of use of these grammatical structures were also calculated from the narratives. There were no statistically significant differences between the three age groups on standard scores for the TVIP or scores for the parent questionnaires, indicating that the three age groups were comparable. For the developmental language measures there was an increasing iii developmental pattern for NU-TU, MLTU and SUB-I, but no changes were found for GRE-TU. Statistically significant changes for the productive use of the grammatical structures of interest to this study were almost always seen between 3 and 4 years of age. Adult use of these grammatical structures was always statistically significantly more correct than child productions. This investigation provides novel normative data for NU-TU, MLTU, SUB-I and GRE-TU for preschool children. This investigation also offers original data on the productive use of object pronouns, articles, adjectives and plurals across the preschool years. The language battery used in this investigation proved to be sensitive to developmental changes between 3 and 4-5 year olds and has the potential to be used as an eventual diagnostic tool for the identification of children with language disorders. Speech-language pathologists who work with Spanish- speaking children will be able to use this normative information to conduct more objective language assessments. iv A la memoria de mi abuelo, el hombre más sabio que ha existido en mi mundo.

  • Teachers' Opinions of the Assessment of Sequential Bilinguals for Primary
    Teachers’ opinions of the assessment of sequential bilinguals for primary/specific language impairment in the first years of formal education in Norway Ivana Randjic Master’s Dissertation Department of Special Needs Education Faculty of Educational Sciences UNIVERSITY OF OSLO This dissertation is submitted in part fulfillment of the joint degree of MA/Mgr. Special and Inclusive Education – Erasmus Mundus University of Roehampton, University of Oslo and Charles University Autumn 2014 II III Teachers’ opinions on assessment of the assessment of sequential bilinguals for primary/specific language impairment in the first years of formal education in Norway IV © Ivana Randjic 2014 Teachers’ opinions of the assessment of sequential bilinguals for primary/specific language impairment in the first years of formal education in Norway Ivana Randjic http://www.duo.uio.no/ Trykk: Reprosentralen, Universitetet i Oslo V Abstract The study was set to look into teachers’ opinions on assessment of specific (primary) language impairment (SLI/PLI) in sequential bilinguals in the first grades of formal schooling in Norway. In order to achieve the main goal of the thesis 3 research questions were posed: What are the teachers’ experiences with bilingualism in their classroom? What are the teachers’ experiences with specific (primary) language impairment? What are the teachers’ opinions on tools and procedures of this assessment? SLI/PLI is affecting a certain percentage of monolingual as well as bilingual children. In the midst of sequential bilingualism SLI/PLI may be difficult to discover. The study was interested in teachers’ perspectives of the issue. Namely, what was to be seen was how teachers cope with this practical matter of every day incidence and what their opinions on the matter were.

  • Bilingual/Multilingual Handout
    Bilingualism/Multilingualism Children’s Support Solutions Bilingualism/Multilingualism Worldwide, there are more people who speak two or more languages than people who speak only one language.i So, in fact, multilingualism is the norm, while learning only one language is the exception. There are many ways to learn a second or third language: one language at home and a different language at daycare, two languages at home, two languages at home and a third at school, just to name a few. Languages can be learned at the same time (simultaneous bilingualism) or one after the other (sequential bilingualism). A second language can also be learned later in childhood or even in adulthood. Being skilled in more than one language brings about many advantages which include increased employment opportunities and sharpened cognitive skills.ii Nonetheless, there are many myths surrounding multilingualism, especially when we are talking about children with delays or impairment in one or more areas of their development. childrensupportsolutions.com Myth # 1 Myth # 2 Myth # 3 Exposing my child to two or more To avoid confusing my child, people If my child is having difficulty learning languages will lead to language around him should each speak only a first language, I should not expose confusion: one language: him to a second or third language: FALSE. Children are generally FALSE. We now know that this is FALSE. Many believe that this very good at knowing which not necessary and, in fact, it is very is true because they think that language is which. Many do hard to do. Even when we think we if one language is hard, two or mix words from each language are only using one language, we more languages must be harder.

  • New Paradigm for the Study of Simultaneous V. Sequential Bilingualism
    New Paradigm for the Study of Simultaneous v. Sequential Bilingualism Suzanne Flynn1, Claire Foley1 and Inna Vinnitskaya2 1MIT and 2University of Ottawa 1. Introduction Mastering multiple languages is a commonplace linguistic achievement for most of the world’s population. Chomsky (in Mukherji et al. 2000) notes that “In most of human history and in most parts of the world today, children grow up speaking a variety of languages…” Clearly, multilingualism “is just a natural state of the human mind.” Notably, most of this language learning occurs in untutored, naturalistic settings and throughout the lifespan of an individual. The false sense of language homogeneity and monolingualism that is often heralded in the United States, at least in certain regional sections, is clearly a historical artifact. As Chomsky notes: Even in the United States the idea that people speak one language is not true. Everyone grows up hearing many different languages. Sometimes they are called “dialects or stylistic variants or whatever” but they are really different languages. It is just that they are so close to each other that we don’t bother calling them different languages (Chomsky, in Mukherji et al., 2000:19 ) A conclusion is that every individual, by virtue of living within a community, is bilingual1 in some sense. Further, this means that in the same sense there is essentially universal multilingualism in the world. Despite the centrality of multilingualism to the human experience, however, questions persist concerning how learners construct new language

Whatever the approach, being bilingual is at the heart of a collective interest and stirs up controversy. There is a very important gap between the linguistic reality lived by many children and what political institutions believe or wish. Both research (Garcia, 1983; Harding-Esch & Riley, 2003; among others) and the evidence by numbers of speakers all over the world show that multilingualism is the norm.

  • An Introduction to Psycholinguistics Examines the Psychology of Language As It Relates to Learning, Mind and Brain As Well As to Aspects of Society and Culture
    0582505755_cover 5/10/05 8:00 am Page 1 PSYCHOLINGUISTICS AN INTRODUCTION TO General Editors: Geoffrey Leech and Mick Short An Introduction to Psycholinguistics examines the psychology of language as it relates to learning, mind and brain as well as to aspects of society and culture. How do we learn to speak and to understand speech? Is language unique to humans? Does language influence culture? Using non-technical language, and providing concrete examples, the authors explore: • How children learn to speak and read their native language • Deaf language education • Case studies of wild children and animals and what we can learn from these • Second language acquisition, second language teaching methods, and the problems associated with bilingualism • Language and the brain SECOND • The relationship between thought and language EDITION In this new edition the authors propose a radical new theory of grammar – natural grammar – which unlike other theories can account for both speech comprehension and speech production. Also taking into account the extensive growth in theory, research and practice, this new edition is an accessible and focused introduction to the key issues and the latest research in the field of psycholinguistics. Danny D. Steinberg is Professor Emeritus of Surugadai University and has previously taught at University of Hawaii and Rikkyo University. He is author of a number of books on semantic theory and psycholinguistics, including Semantics: An Interdisciplinary Reader in Philosophy, Linguistics and Psychology (with L. Jakobovits, 1971) and Psycholinguistics: Language, Mind and World (with H. Nagata and D. Aline, 2nd edition, 2000). Natalia V.

People may happen to be bilingual either by acquiring two languages parallelly in their life since childhood or learn with the passage of time as sequential and simultaneous bilinguals. The current study aims to find out the role of language therapists, in terms of supporting parents and teachers, to benefit maximum out of this dual-language ability of their young children, for this case studies were conducted to investigate the question and it was concluded that balanced use of both languages help a child to perform well with proper guidance of language professionals to the parents and teachers. Furthermore, parents always seem trying their child become bilingual because they consider it a positive thing for the better future of their child.
