Frontonasal Dysplasia, Severe Neuropsychological Delay, and Midline Central Nervous System Anomalies: Report of 10 Brazilian Male Patients

Here we report on 10 male patients with frontonasal dysplasia, cleft lip/palate, mental retardation, lack of language acquisition, and severe central nervous system involvement. Imaging studies disclosed absence of the corpus callosum, midline cysts, and an abnormally modeled cerebellum. Neuronal heterotopias were present in five patients and parieto-occipital encephalocele in three patients. We suggest that this pattern found exclusively in males, most likely represents a newly recognized syndrome distilled from the group of disorders subsumed under frontonasal dysplasia.

Cross-situational learning of object-word mapping using Neural Modeling Fields

The issue of how children learn the meaning of words is fundamental to developmental psychology. The recent attempts to develop or evolve efficient communication protocols among interacting robots or Virtual agents have brought that issue to a central place in more applied research fields, such as computational linguistics and neural networks, as well. An attractive approach to learning an object-word mapping is the so-called cross-situational learning. This learning scenario is based on the intuitive notion that a learner can determine the meaning of a word by finding something in common across all observed uses of that word. Here we show how the deterministic Neural Modeling Fields (NMF) categorization mechanism can be used by the learner as an efficient algorithm to infer the correct object-word mapping. To achieve that we first reduce the original on-line learning problem to a batch learning problem where the inputs to the NMF mechanism are all possible object-word associations that Could be inferred from the cross-situational learning scenario. Since many of those associations are incorrect, they are considered as clutter or noise and discarded automatically by a clutter detector model included in our NMF implementation. With these two key ingredients - batch learning and clutter detection - the NMF mechanism was capable to infer perfectly the correct object-word mapping. (C) 2009 Elsevier Ltd. All rights reserved.

Klassrumsinteraktion i de tidiga skolåren : flerspråkiga elever i skolans språkliga vardag

Classroom interaction is particularly important for those students who learn school knowledge in a second language. In this article two episodes of whole class teaching in pre-school and standard one are analyzed. The analysis shows the importance of making teachers aware of interactional patterns in classrooms. Although knowledge was presented clearly and concretely and teachers used routines that made norms explicit, inconsistencies in interactional patterns made the role of the teacher stand out as unclear. Whole class teaching of this type does not provide students with such linguistic and intellectual demands that are necessary for their language development.

LA ANSIEDAD Y SU RELACIÓN CON LA EXPRESIÓN ORAL EN EL APRENDIZAJE DE LENGUAS EXTRANJERAS : Una elaboración de revisión sistemática de la literatura

La importancia de la dimensión afectiva que acompaña el proceso de adquisición de lenguas extranjeras es indiscutible. Sin embargo, a pesar de esta realidad, y de la evolución de los enfoques comunicativos como métodos de enseñanza de idiomas, la literatura continúa asegurando la existencia de aprensión lingüística en el aula y su efecto debilitador en el proceso de aprendizaje de una nueva lengua. Este estudio tiene como objetivo examinar cómo el aprendiz experimenta la variable de la ansiedad al expresarse oralmente y en qué medida el profesorado de lenguas extranjeras puede lograr crear condiciones en la clase que reduzcan los niveles de ansiedad. En este trabajo utilizamos la revisión sistemática de literatura como estrategia de investigación, un método que constituye una buena herramienta, permitiéndonos sintetizar coherentemente, de forma rigurosa, los resultados de los estudios empíricos sobre el fenómeno de la ansiedad. Los análisis revelan, en primer lugar, que los síntomas experimentados por aprendices de una nueva lengua suelen manifestarse en cada uno de los niveles que integran al individuo, en un nivel emocional, psicológico, fisiológico, de comportamiento y psicopedagógico; en segundo lugar, los investigadores plantean diversas estrategias a nivel psicológico, pedagógico y socio ambiental con el objetivo principal de incrementar en el aprendiz una serie de recursos personales para hacer frente a la ansiedad. Comentamos las implicancias pedagógicas de estos resultados para una mejor comprensión de la ansiedad y del aprendizaje de una lengua extranjera.

Attitudes Towards and Uses of the Japanese Adverbzenzen by Swedish Learners of Japanese

The word zenzen is an adverb that is used frequently in daily conversational Japanese. From the Meiji period (1868-1912) until the early Showa period (1924-1989) the word was used together with both affirmative and negative words to form expressions. In the early Showa period the grammatical rules in education changed so that the only acceptable use was together with a negative word. From the 1990’s onward, the use together with an affirmative word has made a comeback especially among younger Japanese people. However even though the usage together with an affirmative word has made a comeback and was considered normal once in history, in today’s society it is still considered as slang and thus not recommended usage in formal situations. Foreign language learners however, tend not to learn a language only by textbooks but also by imitating the language of native Japanese speakers and Japanese popular culture. This may lead to a confusion regarding what words are acceptable to use in conversations. Therefore in this study, an online survey that examines the usage and attitudes regarding the word zenzen aimed at Japanese language learners at Swedish universities was conducted. The results of the survey showed that although a majority of the learners showed a good understanding of the usage, more than half of the learners displayed a feeling of confusion regarding the usage of the word. The gender comparison regarding the usage showed no major differences. Having lived in Japan, having Japanese friends whom you speak Japanese with regularly and length of Japanese study was associated with an increased understanding of the usage. Regular consumption of Japanese popular culture, however, was not associated with an increased understanding of the usage. A literature analysis was also conducted to examine the attitudes regarding the usage of zenzen in a variety of books with topics including business language and books aimed at Japanese language teachers. The results showed that zenzen used together with a negative word was considered as the norm while zenzen used together with an affirmative word was not recommended to be used in formal situations. When recommending proper usage of the word zenzen together with an affirmative word to foreign learners of Japanese, hijou-ni and totemo was seen as better alternatives to zenzen in a formal situation.

Attitudes towards the minority variety Caló in the south of Spain : a sociolinguistic study

Caló is a variety spoken by the Spanish Calé (i.e. the Roma). It belongs to a group of languages referred to as “Para-Romani”, characterized by Romani vocabulary, but largely non-Romani morphology, phonology and syntax, in the case of Caló deriving from Spanish. According to previous research carried out – with focus on the vocabulary and the grammar of this variety – Caló is on its way to extinction. However, there is an expressed interest in reintroducing a form called “Romanó-Caló”. Attitudes play an important role in minority language maintenance as well as in order for a revitalization project to be successful. The aim of this study is to measure the attitudes that both Calé and non-Calé have towards Caló and Caló speakers, a type of study never carried out in the past. The methods applied are both direct and indirect. In total, 231 informants listened to different recordings of voices acting as either a “Spanish speaking person” or a “Caló speaking person”, a technique referred to as ‘matched guise’, answering questions related to the voices on attitude scales. Furthermore, 182 of the informants rated their agreement or disagreement to positive and negative items towards Caló and its speakers on a Likert scale. The results of the analysis indicate that the attitudes differ towards Caló and Caló speakers, depending on the informant’s (a) ethnicity (b) contact with Caló as well as with Caló speakers, and (c) gender. It is those who – in their own opinion – belong to the ethnic group Calé, as well as those who claim that they have some contact with the variety and its speakers, who show positive attitudes in both parts of the study. The women also show more positive attitudes than the men. It is also possible to note positive attitudes towards the variety and its speakers among the subjects with a high level of knowledge of Caló words, as well as among those with the highest willingness to use Caló. These observations suggest that a revitalization project of the variety Caló has a clear chance of being successful.

Duas vertentes da ontogênese da linguagem no desenvolvimento cognitivo

Este estudo pretende trazer uma contribuição à discussão da relação linguagem-cognição, através do exame de um aspecto restrito do problema: a hipótese de uma base cognitiva para aquisição de linguagem. O modelo teórico piagetiano é analisado em sua explicação da ontogenese da linguagem como resultante das construções da inteligência sensório-motora. Alguns de seus aspectos são questionados, a possibilidade de sua explicitação em forma de hipótese verificável é examinada e a literatura é analisada em busca de evidências relevantes. A principal lacuna constatada é a visão de linguagem restrita a aspectos de desempenho, sendo levado em conta apenas o começo da emissão de palavras na quase totalidade das pesquisas. Ainda dentro de uma perspectiva construtivista, o esboço de um novo modelo teórico é proposto, incluindo a discussão da ontogenese da compreensão de linguagem. Hipóteses decorrentes da proposta teórica, especialmente a de início da possibilidade de tratar o signo linguístico antes do estágio VI, são formuladas e verificadas por pesquisa empírica. Esta inclui um estudo longitudinal e outro transversal do desenvolvimento linguístico e cognitivo de 45 crianças entre 8 e 18 meses. O desenvolvimento da compreensão é comparado em diversos aspectos ao da produção ou fala. Verifica-se que o primeiro começa mais cedo, é mais rápido e atinge um vocabulário maior e um nível mais complexo na faixa etária estudada. Há evidências ainda de diferenças no papel da imitação na construção do vocabulário nas duas vertentes. Observa-se um início de resposta mais generalizada e sistemática à linguagem a partir de nove meses, ocasião em que a criança se mostra capaz de coordenação de reações circulares secundárias e quando consegue reconstruir mentalmente um objeto invisível a partir de uma fração visível. Considera-se que esta resposta já envolve a decodificação de signos e a diferenciação significante-significado, numa etapa preliminar de um processo evolutivo que se entrelaça com a formação de conceitos. Os dados nao permitem a identificação de prê-requisitos cognitivos para aquisição de liguagem, mas dois aspectos podem ser destacados como correlatos do início do processo de compartilhar o signo linguístico: a possibilidade da criança compreender que tem um nome e responder a ele e uma intencionalidade primitiva. Os resultados apoiam as hipóteses formuladas e sugerem que as construções finais do período sensório-motor não são condições necessárias para aquisição de linguagem e que esta não ê consequência direta do desenvolvimento cognitivo. Novos estudos são necessários para suprir as limitações desta pesquisa e verificação das implicações decorrentes dos resultados obtidos.

A expressão do FOXP2 : uma introdução ao estudo das relações entre genes e linguagem

A aquisição da linguagem é um processo invariavelmente dependente da exposição ao ambiente. Contudo, a mais famosa e controversa hipótese desenvolvida por Chomsky sustenta que a criança traz para o processo de aprendizagem da língua um conjunto de recursos específicos – a Gramática Universal – para superar a pobreza de estímulos do ambiente e construir uma gramática final adequada, composta por princípios universais e parâmetros fixados de acordo com a experiência na comunidade lingüística. A Gramática Universal é, assim, entendida como uma dotação genética, necessária, mas não suficiente, para a aquisição da linguagem. Para além da hipótese do inatismo – central à tradição gerativista – a relação entre genes e linguagem vem sendo investigada há muitos anos, com evidências significativas de transmissão hereditária e etiologia genética para diversos tipos de distúrbios de linguagem. Mais recentemente, em 2001, foi descoberto o primeiro caso de um gene, o FOXP2, implicado na habilidade de adquirir e desenvolver a fala e a linguagem. Este trabalho parte de uma introdução ao processo de aquisição da linguagem em uma perspectiva inatista (Capítulo I) para enfocar os aspectos centrais à organização biológica da faculdade da linguagem (Capítulo II), propondo, a partir da análise dos efeitos da mutação do gene FOXP2, uma discussão introdutória sobre como o estudo dos distúrbios do desenvolvimento da linguagem, avaliados a partir de suas características fenotípica e genotípica, pode contribuir para a exploração de questões fundamentais acerca do desenvolvimento lingüístico e cognitivo (Capítulo III).

O papel da leitura nas aulas de inglês: uma análise segundo a percepção dos professores do ensino médio de escolas públicas estaduais de Natal

This dissertation aims at investigating the teachers beliefs about the role of the reading ability in English at public state high schools in Natal and identifying the social value of the process of learning English for students of a foreign language. From the understanding of studies on reading, both in the field of Cognitive Psychology, as in Gibson & Levin (1975), as in the area of Psycholinguistics, as in Goodman (1970) and Del Re (2006), We researched the teachers perceptions about the skills and competencies that should permeate their educational practices, through their knowledge about theories of language acquisition as Cognitivism (Piaget, 1961) and Social Interactionism (Vygotsky, 1979) and the official documents (PCNEM, 1999; PCN+, 2002 ) that are the parameters for teaching a foreign language. We took into consideration other factors that influence the choice of the goals and the objectives to be worked out, such as: intensity of teachers workload, number of classes and students per class for each teacher, materials and technologies available, among other factors that will play an important role in the choice of the appropriate methodologies. To conduct a case study, two questionnaires were used in the construction of direct interviews with fourteen English teachers in twenty schools. According to data on the teachers beliefs we could find that for them the reading ability does not seem to have an special treatment in the teaching of a foreign language due to factors that undermine this process and therefore make teachers do not realize the real objectives of teaching English at public state high schools in Natal. As a consequence, the current process of education complicates the formation of autonomous learners capable of fighting for a social transformation

Errors in nonword repetition: bridging short- and long-term memory

According to the working memory model, the phonological loop is the component of working memory specialized in processing and manipulating limited amounts of speech-based information. The Children's Test of Nonword Repetition (CNRep) is a suitable measure of phonological short-term memory for English-speaking children, which was validated by the Brazilian Children's Test of Pseudoword Repetition (BCPR) as a Portuguese-language version. The objectives of the present study were: i) to investigate developmental aspects of the phonological memory processing by error analysis in the nonword repetition task, and ii) to examine phoneme (substitution, omission and addition) and order (migration) errors made in the BCPR by 180 normal Brazilian children of both sexes aged 4-10, from preschool to 4th grade. The dominant error was substitution [F(3,525) = 180.47; P < 0.0001]. The performance was age-related [F(4,175) = 14.53; P < 0.0001]. The length effect, i.e., more errors in long than in short items, was observed [F(3,519) = 108.36; P < 0.0001]. In 5-syllable pseudowords, errors occurred mainly in the middle of the stimuli, before the syllabic stress [F(4,16) = 6.03; P = 0.003]; substitutions appeared more at the end of the stimuli, after the stress [F(12,48) = 2.27; P = 0.02]. In conclusion, the BCPR error analysis supports the idea that phonological loop capacity is relatively constant during development, although school learning increases the efficiency of this system. Moreover, there are indications that long-term memory contributes to holding memory trace. The findings were discussed in terms of distinctiveness, clustering and redintegration hypotheses.

Uso de expressões orais durante a implementação do recurso de comunicação suplementar e alternativa

The literature has discussed the importance of early implementation of augmentative and alternative systems with people with various disabilities. This discussion is related to concerns about language acquisition and development within the various expressive possibilities. Researchers advise that starting intervention early through resources and procedures using augmentative and alternative communication does not impede speech acquisition and development. This paper aimed to describe oral expressive abilities during the implementation of augmentative and alternative communication with a student with cerebral palsy. An 11-year-old student with cerebral palsy participated in the augmentative and alternative communication program for two years. Twelve sessions were selected during the first year of the intervention. The sessions were filmed and the augmentative and alternative communication resource procedures were transcribed. The categories of analysis were defined as verbal expression; nonverbal expression and verbal and nonverbal expression associated. The results of this study identified that augmentative and alternative communication resources supported the use of verbal expression such as vocalizations, words and unintelligible oral expressions.
