The abstraction of form in semantic categories.

Undergraduates were asked to generate a name for a hypothetical new exemplar of a category. They produced names that had the same numbers of syllables, the same endings, and the same types of word stems as existing exemplars of that category. In addition, novel exemplars, each consisting of a nonsense syllable root and a prototypical ending, were accurately assigned to categories. The data demonstrate the abstraction and use of surface properties of words.

Estruturadores do discurso na aula de português em Moçambique

O nosso estudo debruça-se sobre o uso de estruturadores do discurso na interacção verbal, em contexto pedagógico. As nossas referências teóricas estão vinculadas à Análise do Discurso, quer à escola francesa (com origem na Linguística), quer à escola anglo-saxónica (com origem na Antropologia). Em relação à área da Linguística, buscámos os pressupostos da Pragmática, Sociolinguística e Psicolinguística; relativamente à Antropologia, seguimos as abordagens etnográficas, etnometodológicas e interaccionistas. Nesta pesquisa participaram 15 professores e 778 alunos de cinco escolas do ensino secundário/equiparado da cidade da Beira e da região de Maputo (Moçambique), que integravam, nomeadamente, as turmas do 1.º e 2.º ano do ramo comercial e 9.ª e 10.ª classe do ensino secundário geral. Observámos 40 aulas, das quais foram transcritas e analisadas 10 aulas. A transcrição e a anotação foram realizadas com o auxílio do programa Transcriber. Usámos métodos qualitativos e quantitativos e, predominantemente, procedimentos descritivos. Identificámos 4700 marcadores discursivos distribuídos nas seguintes subcategorias: marcadores discursivos directivos, marcadores discursivos de confirmação, marcadores discursivos de natureza fáctica e de concordância e as interjeições como marcadores discursivos. Os resultados da nossa pesquisa permitiram-nos concluir que os marcadores discursivos e as disfluências desempenham funções ligadas à estruturação textual-interactiva. Estes fenómenos linguísticos, ao estruturarem o discurso de professores e alunos, contribuem para a produção/compreensão de sentido das frases.

Psychocentricity and participant profiles: implications for lexical processing among multilinguals

Lexical processing among bilinguals is often affected by complex patterns of individual experience. In this paper we discuss the psychocentric perspective on language representation and processing, which highlights the centrality of individual experience in psycholinguistic experimentation. We discuss applications to the investigation of lexical processing among multilinguals and explore the advantages of using high-density experiments with multilinguals. High density experiments are designed to co-index measures of lexical perception and production, as well as participant profiles. We discuss the challenges associated with the characterization of participant profiles and present a new data visualization technique, that we term Facial Profiles. This technique is based on Chernoff faces developed over 40 years ago. The Facial Profile technique seeks to overcome some of the challenges associated with the use of Chernoff faces, while maintaining the core insight that recoding multivariate data as facial features can engage the human face recognition system and thus enhance our ability to detect and interpret patterns within multivariate datasets. We demonstrate that Facial Profiles can code participant characteristics in lexical processing studies by recoding variables such as reading ability, speaking ability, and listening ability into iconically-related relative sizes of eye, mouth, and ear, respectively. The balance of ability in bilinguals can be captured by creating composite facial profiles or Janus Facial Profiles. We demonstrate the use of Facial Profiles and Janus Facial Profiles in the characterization of participant effects in the study of lexical perception and production.

The nature of compounds: A psychocentric perspective

Although compound words often seem to be words that themselves contain words, this paper argues that this is not the case for the vast majority of lexicalized compounds. Rather, it is claimed that as a result of acts of lexical processing, the constituents of compound words develop into new lexical representations. These representations are bound to specific morphological roles and positions (e.g., head, modifier) within a compound word. The development of these positionally bound compound constituents creates a rich network of lexical knowledge that facilitates compound processing and also creates some of the well-documented patterns in the psycholinguistic and neurolinguistic study of compounding.

Noam Chomsky, un représentant de la tradition humaniste et critique en éducation

Noam Chomsky, figure notoire du cognitivisme innéiste en psycholinguistique, est aussi un important penseur américain et activiste politique ayant écrit sur une multitude de sujets, issus de domaines variés : politique interne et étrangère des États-Unis, critique des médias de masse et enjeux sociaux liés aux droits de l’Homme, pour ne nommer que ceux-ci. Par contre, et malgré l’abondance de ses écrits à ce propos, Chomsky est, à ce jour, très peu étudié en philosophie de l’éducation : ce mémoire de maîtrise s’inscrit ainsi dans une perspective d’exploration, de définition et d’analyse de la pensée éducative chomskyenne, dans le but de présenter et réfléchir la portée possible d’une telle pensée dans l’axe philosophique des recherches en éducation. Devant la rareté, voire l’absence de recherches francophones et anglophones concernant notre objet d’étude, plus d’une centaine de livres, articles, entrevues et vidéos portant sur la philosophie chomskyenne et celle de grands penseurs humanistes, critiques ou opposés aux postulats chomskyens ont été retenus, lus et analysés dans le cadre de ce projet. Deux objectifs précis ont guidé ce mémoire : d’abord, présenter et analyser la pensée éducative chomskyenne en regard de ses fondements philosophiques et de ses ancrages intellectuels dans les traditions humaniste et critique en philosophie éducative, puis mettre en lumière l’unicité de cette pensée par rapport à ces traditions et à quelques courants opposés en éducation. Au terme de ce mémoire, nous espérons ainsi répondre aux questions suivantes : dans quelle mesure Chomsky s’inscrit-il dans les traditions humaniste et critique en éducation? Peut-il être considéré comme un héritier de la pensée de certains philosophes particuliers? En quoi sa pensée, relative à la philosophie de l’éducation, est-elle pertinente et innovante pour ce domaine fondamental? Et, finalement, quelles critiques pouvons-nous lui adresser?

La influencia de factores educativos y familiares sobre el aprendizaje de una segunda lengua, y los efectos sobre la inteligencia y cognición

Actualmente, la investigación científica acerca de la influencia de los factores educativos y familiares en el aprendizaje de una segunda lengua (L2) es limitada. En comparación, los efectos que tiene la L2 en la inteligencia y cognición han sido más estudiados. Por esta razón, el artículo presenta una revisión de la literatura empírica existente que relaciona lo mencionado anteriormente, ampliando así la temática del bilingüismo. Se buscaron artículos en cuatro bases de datos (PSICODOC, ISI Web of knowledge y SCOPUS), usando palabras claves específicas, en el periodo de 1990 hasta el 2012. De 79 artículos encontrados, 34 cumplieron con los criterios de inclusión para la revisión. Asimismo, se tuvieron en cuenta dos libros, de los cuales se revisó un capítulo por cada uno según los mismos criterios. En conjunto, los resultados arrojaron importantes datos teóricos y de investigación que relacionan el éxito en el aprendizaje de una L2 con la inteligencia y cognición, según la influencia de los factores educativos y familiares. En conclusión, se identificaron más factores educativos que familiares; lo cual a concepto de la autora evidencia la limitada investigación que se ha hecho sobre los factores familiares en el bilingüismo actualmente.

Nongenetic inheritance, linguistic competence, prenatal experience and behavior manipulation: recent contributions from behavioral neurobiology and neuropsychology to the explanation of behavior

This article gives an overview of presuppositions and explanations posed by behaviorist psychology (particularly its radical branch), cognitive–nativist sciences (i.e. psycholinguistics and a branch of cognitive psychology) and other disciplines regarding important psychological events such as anxiety, stress, fear, mood states and language. In relation to the discussion of environment versus genetics, contributions from behavioral neurobiology and neuropsychology are added, showing evidence of traits that can be multigenerationally inherited in a non-genetic way, which have an impact thought the life of organisms and on their way of interacting with the environment; ways in which behavior can be altered by recently unsuspected environmental agents or events, and the overlooked role of prenatal experiences in the explanation of behavior. The evidence calls into question presuppositions made by the academic disciplines listed above, and suggests alternative behavior reinterpretations and explanations

Contribution from neuropsychology to the study of semantic memory

Semantic memory has been studied from various fields. The first models emerged from cognitive psychology from the hand of the division proposed by Tulving between semantic and episodic memory. Over the past thirty years there have been parallel developments in the fields of psycholinguistics, cognitive psychology and cognitive neuropsychology. The present work is to review the contributions that have emerged within the neuropsychology to the study of semantic memory and to present an updated overview of the points of consensus. First, it is defined the term "semantics" conceptually within the field of neuropsychology. Then, there is a dichotomy that passes through both psychological and neuropsychological models on semantic memory: the existence of modals versus amodal representations. Third, there are  developed the main theoretical models in neuropsychology that emerged in an attempt to explain categoryspecific semantic deficits. Finally, more robust contributions and points that still generate some discussion are reviewed.

Argument omissions in preschool Catalan and Spanish speaking children with SLI

El presente artículo describe tres estudios sobre la producción del verbo y la estructura argumental en niños con Trastorno Específico del Lenguaje (TEL) usando diferentes metodologías. El primero es un estudio observacional que usa una muestra de habla espontánea. El segundo usa una tarea experimental de denominación de oraciones como resultado de la observación de videos de acciones. El tercero comprende la tarea de denominación de oraciones con imágenes estáticas en eventos con diferente complejidad argumental. Aunque los datos concretos varían en función de la metodología usada, hay una clara evidencia de que los niños de habla catalana y española con TEL presentan especiales dificultades en la producción de verbos con una alta complejidad en relación a la estructura argumental y cometen errores en la especificación de los argumentos obligatorios. Se concluye que tanto limitaciones en el procesamiento como déficits en la representación semántica de los verbos pueden estar implicados en estas dificultades

Estrategias memorísticas y aprendizaje de las expresiones idiomáticas en lengua extranjera: el papel cognitivo de la iconicidad fraseológica

En este estudio, mostraremos principalmente la importancia que las imágenes formadas por los componentes fraseológicos pueden adquirir desde un punto de vista no sólo puramente lingüístico, sino también psicolingüístico si se contempla el posible carácter analizable y transparente de muchas EI. Explicaremos cómo se puede utilizar esta iconicidad para fomentar el desarrollo de estrategias de aprendizaje (especialmente vinculadas a la descodificación metafórica o a la asociación icónica con expresiones de la LM) que suponen para el alumno un alto grado de implicación cognitiva. Teniendo en cuenta dos factores importantes para la memorización de nuevas EI -su grado de transparencia semántica y su grado de conexión icónica con la LM-, propondremos en un apartado experimental investigar acerca del impacto memorístico e interlingüístico que se puede atribuir al trabajo de enfoque icónico y verificar la influencia que la combinación de los dos factores citados puede ejercer en este ámbito.

The prompt hypothesis: clarification requests as corrective input for grammatical errors

The potential of clarification questions (CQs) to act as a form of corrective input for young children's grammatical errors was examined. Corrective responses were operationalized as those occasions when child speech shifted from erroneous to correct (E -> C) contingent on a clarification question. It was predicted that E -> C sequences would prevail over shifts in the opposite direction (C -> E), as can occur in the case of nonerror-contingent CQs. This prediction was tested via a standard intervention paradigm, whereby every 60s a sequence of two clarification requests (either specific or general) was introduced into conversation with a total of 45 2- and 4-year-old children. For 10 categories of grammatical structure, E -> C sequences predominated over their C -> E counterparts, with levels of E -> C shifts increasing after two clarification questions. Children were also more reluctant to repeat erroneous forms than their correct counterparts, following the intervention of CQs. The findings provide support for Saxton's prompt hypothesis, which predicts that error-contingent CQs bear the potential to cue recall of previously acquired grammatical forms.

Prosodic abilities in Spanish and English children with Williams syndrome: a cross-linguistic study

The aim of this study was to compare the prosodic profiles of English and Spanish-speaking children with WS, examining cross-linguistic differences. Two groups of children with WS, English and Spanish, of similar chronological and nonverbal mental age, were compared on performance in expressive and receptive prosodic tasks from the Profiling Elements of Prosody in Speech-Communication (PEPS-C) battery in its English or Spanish version. Differences between the English and Spanish WS groups were found regarding the understanding of affect through prosodic means,using prosody to make words more prominent, and imitating different prosodic patterns. Such differences between the two WS groups on function prosody tasks mirrored the cross-linguistic differences already reported in typically developing children.

Once upon a time, there was a pulchritudinous princess…: the role of word definitions and multiple story contexts in children’s learning of difficult vocabulary

The close relationship between children’s vocabulary size and their later academic success has led researchers to explore how vocabulary development might be promoted during the early school years. We describe a study that explored the effectiveness of naturalistic classroom storytelling as an instrument for teaching new vocabulary to six- to nine-year-old children. We examined whether learning was facilitated by encountering new words in single versus multiple story contexts, or by the provision of age-appropriate definitions of words as they were encountered. Results showed that encountering words in stories on three occasions led to significant gains in word knowledge in children of all ages and abilities, and that learning was further enhanced across the board when teachers elaborated on the new words’ meanings by providing dictionary definitions. Our findings clarify how classroom storytelling activities can be a highly effective means of promoting vocabulary development.
