Issues and benefits of using 3D Interfaces: visual and verbal tasks

Spatial memory is important for locating objects in hierarchical data structures, such as desktop folders. There are, however, some contradictions in literature concerning the effectiveness of 3D user interfaces when compared to their 2D counterparts. This paper uses a task-based approach in order to investigate the effectiveness of adding a third dimension to specific user tasks, i.e. the impact of depth on navigation in a 3D file manager. Results highlight issues and benefits of using 3D interfaces for visual and verbal tasks, and introduces the possible existence of a correlation between aptitude scores achieved on the Guilford- Zimmerman Orientation Survey and Electroencephalography- measured brainwave activity as participants search for targets of variable perceptual salience in 2D and 3D environments.

The acquisition of person and number morphology within the verbal domain in Early Greek

The aim of this paper is to examine the acquisition pattern of person and number verb morphology within the generative framework and to compare the results of the analyses with previous research in Greek and other European languages. The study considers previous data on the acquisition of subject-verb agreement, and thereafter, examines the acquisition of person and number morphology in a new dataset of two monolingual Greek-speaking children. The analyses present quantitative data of accuracy of person and number marking, error data, and qualitative analyses addressing the productivity of person and number marking. The results suggest that person and number morphology is used correctly and productively from a very early age in Greek speaking children. The findings provide new insight into early Greek language acquisition and are also relevant for research in early development of languages with rich inflectional morphology.

Memo test: standardisation of computerised assessment of auditory verbal short-term memory

Short-term memory (STM) impairments are prevalent in adults with acquired brain injuries. While there are several published tests to assess these impairments, the majority require speech production, e.g. digit span (Wechsler, 1987). This feature may make them unsuitable for people with aphasia and motor speech disorders because of word finding difficulties and speech demands respectively. If patients perceive the speech demands of the test to be high, the may not engage with testing. Furthermore, existing STM tests are mainly ‘pen-and-paper’ tests, which can jeopardise accuracy. To address these shortcomings, we designed and standardised a novel computerised test that does not require speech output and because of the computerised delivery it would enable clinicians identify STM impairments with greater precision than current tests. The matching listening span tasks, similar to the non-normed PALPA 13 (Kay, Lesser & Coltheart, 1992) is used to test short-term memory for serial order of spoken items. Sequences of digits are presented in pairs. The person hears the first sequence, followed by the second sequence and s/he decides whether the two sequences are the same or different. In the computerised test, the sequences are presented in live voice recordings on a portable computer through a software application (Molero Martin, Laird, Hwang & Salis 2013). We collected normative data from healthy older adults (N=22-24) using digits, real words (one- and two-syllables) and non-words (one- and two- syllables). Their performance was scored following two systems. The Highest Span system was the highest span length (e.g. 2-8) at which a participant correctly responded to over 7 out of 10 trials at the highest sequence length. Test re-test reliability was also tested in a subgroup of participants. The test will be available as free of charge for clinicians and researchers to use.

Parents' verbal communication and childhood anxiety: a systematic review

Parents’ verbal communication to their child, particularly the expression of fear-relevant information (e.g., attributions of threat to the environment), is considered to play a key role in children’s fears and anxiety. This review considers the extent to which parental verbal communication is associated with child anxiety by examining research that has employed objective observational methods. Using a systematic search strategy, we identified 15 studies that addressed this question. These studies provided some evidence that particular fear-relevant features of parental verbal communication are associated with child anxiety under certain conditions. However, the scope for drawing reliable, general conclusions was limited by extensive methodological variation between studies, particularly in terms of the features of parental verbal communication examined and the context in which communication took place, how child anxiety was measured, and inconsistent consideration of factors that may moderate the verbal communication–child anxiety relationship. We discuss ways in which future research can contribute to this developing evidence base and reduce further methodological inconsistency so as to inform interventions for children with anxiety problems.

Verbal short‐term memory performance in pupils with Down Syndrome

Research has shown that verbal short‐term memory span is shorter in individuals with Down syndrome than in typically developing individuals of equivalent mental age, but little attention has been given to variations within or across groups. Differences in the environment and in particular educational experiences may play a part in the relative ease or difficulty with which children remember verbal material. This article explores the performance of 26 Egyptian pupils with Down syndrome and 26 Egyptian typically developing children on two verbal short‐term memory tests: digit recall and non‐word repetition tasks. The findings of the study revealed that typically developing children showed superior performance on these tasks to that of pupils with Down syndrome, whose performance was both lower and revealed a narrower range of attainment. Comparisons with the performance of children with Down syndrome in this study suggested that not only did the children with Down syndrome perform more poorly than the typically developing children, their profile also appeared worse than the results of studies of children with a similar mental age with Down syndrome carried out in western countries. The results from this study suggested that, while deficits in verbal short‐term memory in Down syndrome may well be universal, it is important to recognise that performances may vary as a consequence of culture and educational experiences. The significance of these findings is explored with reference to approaches to education and how these are conceptualised in relation to children with disabilities.

Verbal hygiene in the Hong Kong gay community

This paper explores the status and function of English among gay men in Hong Kong through the analysis of postings about English on a popular gay internet forum. The forum, gayhk.com, while mainly featuring discussions about sex, fashion, entertainment and relationships, also contains a surprising amount of discussion about the English language, mostly taking the form of what Cameron refers to as ‘verbal hygiene’ – the enforcement of language ‘standards’ through the criticism of the language use of particular individuals or groups. The analysis of these postings sees them not just as evidence of language attitudes within the gay community, but also as tools with which Chinese gay men in postcolonial Hong Kong position themselves in relation to one another, in relation to ‘foreign’ gay men, and in relation to the wider population of Hong Kong.

The acquisition of verbal paradigms in Dutch and Greek L2 children: cross-linguistic differences and inflectional defaults

Previous research with children learning a second language (L2) has reported errors with verb inflection and cross-linguistic variation in accuracy and error patterns. However, owing to the cross-linguistic complexity and diversity of different verbal paradigms, the cross-linguistic effects on the nature of default forms has not been directly addressed in L2 acquisition studies. In the present study, we compared accuracy and error patterns in verbal agreement inflections in L2 children acquiring Dutch and Greek, keeping the children’s L1 constant (Turkish). Results showed that inflectional defaults in Greek follow universal predictions regarding the morphological underspecification of paradigms. However, the same universal predictions do not apply to the same extent to Dutch. It is argued that phonological properties of inflected forms should be taken into account to explain cross-linguistic differences in the acquisition of inflection. By systematically comparing patterns in child L2 Dutch and Greek, this study shows how universal mechanisms and target language properties work in tandem in the acquisition of inflectional paradigms.

Variação, contato e mudança linguística em Moçambique e Cabo Verde : A concordância variável de número em sintagmas nominais do português

This study investigates variable noun phrase number agreement (VNA) in two second language varieties of Portuguese, spoken in Maputo, Mozambique and in Mindelo, Cape Verde. Quantitative VARBRUL analysis is carried out based on recordings made in Maputo and Mindelo 2007 and 2008. Previous quantitative studies on VNA in varieties of Brazilian Portuguese (Guy, 1981; Lopes, 2001; Andrade, 2003) as well as on VNA in first and second language varieties of Portuguese from São Tomé (Baxter, 2004; Figueiredo, 2008, 2010) indicate contact between Portuguese and African languages as the main origin of this phenomenon. VNA in Brazilian Portuguese is, however, interpreted by Scherre (1988) and Naro & Scherre (1993, 2007) as the result of language internal drift. Varieties of Portuguese from Mozambique and Cape Verde are particularly interesting to contrast in order to investigate influences from African languages on VNA, as in Mozambique Bantu languages are first languages of the vast majority of Portuguese speakers, whereas in Cape Verde, practically all Portuguese speakers are first language speakers of Cape Verdean Creole, whose substrates are West African, and not Bantu, languages. Comparison is also made with previous studies from Brazil and São Tomé. The results of this study comment previously postulated explanations for VNA in Portuguese in various ways. The analysis of the variables onset age and age stratum indicates that VNA in the analyzed varieties is a phenomenon linked to the acquisition of Portuguese as a second language and/or language contact rather than the result of internal drift. The fact that all the compared varieties tend to mark plural on pre-head components contradicts Bantu transfer as an explanation for this pattern, and raises the need to also consider more general explanations based on language contact. The basic structural similarity between the compared varieties suggests the existence of a grammatical restructuring continuum.

Y ahora toca gramática…… : Un estudio cualitativo sobre las actitudes hacia lagramática y los métodos didácticosde unos profesores del bachillerato sueco

Grammar is one of the most discussed part of language learning. Many studentshave problems understanding how to use the grammatical forms in their ownproduction and communication. The purpose of this work is to investigate theteachers´ attitudes towards grammar and what methods they use when they teachgrammar. The method used in this work is qualitative, with four interviews ofteachers working in the Swedish high school. In order to determine how the teacherswork, we have studied the course plans presented by Skolverket and we have alsostudied what the current research have to say about this. The result shows that theinterviewed teachers mostly vary their methods, using both inductive and deductiveapproaches in order to promote the communicative competence of the students. Theinterviews also show that the teachers have a positive attitude towards grammar,considering it an important part of language learning.

Concordância no diagnóstico radiológico da doença respiratória aguda baixa em crianças

Objetivo: Estudar a concordância no diagnóstico radiológico da doença respiratória aguda baixa (DRAB) em crianças. Métodos: Sessenta radiogramas do tórax de crianças menores de cinco anos foram avaliados, individualmente, por três médicos: um radiologista pediátrico (RP), um pneumologista pediatra (PP) e 1 pediatra experiente no atendimento de sala de emergências (PE). Todas as crianças tinham procurado atendimento por apresentar um quadro agudo de infecção respiratória com aparente participação pulmonar. Os avaliadores desconheciam os diagnósticos originais, mas receberam uma ficha padrão com dados clínicos e laboratoriais dos pacientes no momento da consulta inicial. Variáveis: Agrupadas em cinco categorias: a) qualidade técnica do filme; b) localização da alteração; c) padrões radiográficos; d) outras alterações radiográficas; e) diagnóstico. Análise Estatística: Para estudar a concordância entre as três duplas posíveis de observadores, utilizou-se a estatística de Kappa, aceitándo-se os valores ajustados para viés de prevalência (PABAK). Resultados: Os valores Kappa totais de cada dupla de observadores (RP x PP, RP x PE e PP x PE) foram 0.41, 0.43, e 0.39 respectivamente, o que representa em média, uma concordância interobservadores moderada (0.41). Outras variáveis: “qualidade técnica” teve uma concordância regular (0.30); com “localização”, foi moderada (0.48); com “padrões radiográficos” foi regular (0.29); com “outras alterações radiográficas” foi moderada (0,43); e com “diagnóstico”, regular (0.33). Quanto à concordância global intraobservadores, a mesma foi moderada (0.54), com valores menores dos descritos na literatura. Conclusões: A variabilidade interobservadores é inerente à interpretação dos achados radiológicos, e determinar o diagnóstico exato da DRAB nas crianças tem seus desafíos. Nossos resultados foram similares aos descritos na literatura.

A comunicação não-verbal na sala de aula

O objetivo deste trabalho situa-se a partir dos acréscimos do pensamento cientifico moderno, que em função dos estudos do processo verbal da comunicação humana, visa, agora, um pouco mais adiante, o estudo de seu processo não verbal, onde se sanam velhas dúvidas e propõem-se novos questionamentos acerca da figura Homem. O trabalho analisará as duas dimensões existenciais que o homem estabelece com o mundo: a dimensão verbal, quando da sua apreensão da "imagem de mundo", dentro de suas características psico-linguísticas e a dimensão não-verbal que sobredetermina esta "imagem de mundo", dentro do aspecto psico-biológico do ser. A postulação de uma existência verbal e de uma existência não-verbal, não poderia ser entendida como duas ordens diferentes e antagônicas, mas como duas modalidades de manifestação da existencialidade: o indivíduo participa simultaneamente das duas, como identidade e diferença. E é sob este aspecto que, a sala de aula se revelaria como um micro-universo, cujas coordenadas básicas, informação/formação, articulariam, de fato, as coordenadas existenciais identidade/diferença. Acrescentaria-se, finalmente, que a partir da sala de aula, o indivíduo modelaria a sua realidade conceitual, sendo ao mesmo tempo, por ela modelado. Tal processo se desenvolveria à medida em que o indivíduo reelaborasse a realidade objetiva como sujeito do discurso e seria modelado, à medida em que se deixasse objetivar e impessoalizar-se no discurso cultural. A partir então deste jogo maior do homem, onde se ajustariam as duas dimensões existenciais, que o equilíbrio psico-social do individuo se tentaria, garantindo a sua sobrevivência. Seria desta forma, o espaço sala de aula, franquia maior da individualidade, um campo aberto a educadores e psicologos, fazendo uso mais profilatico que terapêutico ao ajuste do homem a seu grupo e/ou um pouco mais, ao seu próprio sentido humano.

O que a criança nos diz quando parece nada falar? : o desbloqueio do discurso falado através do não-verbal

Esta dissertação tem como base o estudo de caso de uma criança com dificuldade na fala, diagnosticada por neurologista, fonoaudiólogo e psicólogo como apresentando um distúrbio no desenvolvimento global com suspeita de deficiência mental. A metodologia está amparada na forma e na estrutura que FREUD se utiliza na descrição do caso do pequeno Hans (1909), onde a criança é falada por seus pais. Utilizamos como referencial teórico a Psicomotricidade Relacional, a Psicanálise e a Educação Inclusiva, fazendo parte de uma idéia de estrutura interligada e inter-relacionada. Seus fundamentos foram caminhos ao tema desta dissertação ou seja: o que a criança nos diz quando parece nada falar? o desbloqueio do discurso falado através do não-verbal. Este desbloqueio do discurso falado, que no início das sessões propostas pelo pesquisador com base na comunicação não-verbal, apresentava-se, pela criança (estudo de caso), apenas com monossílabas e a repetição de uma palavra “amnei”, foi aos poucos e progressivamente, evoluindo a outras palavras, chegando a frases pequenas, juntamente com sua mudança de comportamento e relacionamento na família e na escola. Nossa abordagem visa fazer emergir da criança seus desejos, seus interesses, suas faltas e falas, através do jogo livre e espontâneo, do brincar, na busca de seu reconhecimento de sujeito diferente, portanto único, ator, atuante. O foco psicoafetivo do sujeito é o cerne de nossa atuação, onde o facilitador, orientador das sessões, deve estar disponível e disposto a interagir mas observando o desejo da criança, favorecendo a realização simbólica de seus desejos e frustrações inconscientes. Desta forma pretendemos apresentar, quem sabe, novas formas e maneiras de abordagens possíveis a serem realizadas com crianças com dificuldades na aprendizagem, procurando restabelecer a dinâmica do desejo do ser, em busca de sua autonomia, utilizando suas possibilidades na resolução dos problemas.
