Balanced bilinguals favor lexical processing in their opaque language and conversion system in their shallow language

Referred to as orthographic depth, the degree of consistency of grapheme/phoneme correspondences varies across languages from high in shallow orthographies to low in deep orthographies. The present study investigates the impact of orthographic depth on reading route by analyzing evoked potentials to words in a deep (French) and shallow (German) language presented to highly proficient bilinguals. ERP analyses to German and French words revealed significant topographic modulations 240-280ms post-stimulus onset, indicative of distinct brain networks engaged in reading over this time window. Source estimations revealed that these effects stemmed from modulations of left insular, inferior frontal and dorsolateral regions (German>French) previously associated to phonological processing. Our results show that reading in a shallow language was associated to a stronger engagement of phonological pathways than reading in a deep language. Thus, the lexical pathways favored in word reading are reinforced by phonological networks more strongly in the shallow than deep orthography.

Lexical Pragmatics and Theory of Mind: The Acquisition of Connectives

The concept of theory of mind (ToM), a hot topic in cognitive psychology for the past twenty-five years, has gained increasing importance in the fields of linguistics and pragmatics. However, even though the relationship between ToM and verbal communication is now recognized, the extent, causality and full implications of this connection remain mostly to be explored. This book presents a comprehensive discussion of the interface between language, communication, and theory of mind, and puts forward an innovative proposal regarding the role of discourse connectives for this interface. The proposed analysis of connectives is tested from the perspective of their acquisition, using empirical methods such as corpus analysis and controlled experiments, thus placing the study of connectives within the emerging framework of experimental pragmatics.

Interchanging lexical resources on the Semantic Web

Lexica and terminology databases play a vital role in many NLP applications, but currently most such resources are published in application-specific formats, or with custom access interfaces, leading to the problem that much of this data is in ‘‘data silos’’ and hence difficult to access. The Semantic Web and in particular the Linked Data initiative provide effective solutions to this problem, as well as possibilities for data reuse by inter-lexicon linking, and incorporation of data categories by dereferencable URIs. The Semantic Web focuses on the use of ontologies to describe semantics on the Web, but currently there is no standard for providing complex lexical information for such ontologies and for describing the relationship between the lexicon and the ontology. We present our model, lemon, which aims to address these gaps

Lexical phrases in telecommunication blogs: a genre analysis

The study presented in this paper aims to provide a description of telecommunication blogs as a genre. Lexical phrases are analysed in order to reach conclusions regarding the nature of the language in these texts and the extent to which the results obtained are comparable with other written or conversational discourse types. Although the departing hypothesis is that the articles in blogs are basically transactional and their main objective is to transfer information, the conclusions point to interaction as a distinctive characteristic of this type of discourse and also to a more careful organization in the comments to the blogs entries than originally expected. RESUMEN. Este trabajo presenta una descripción de los blogs de Telecomunicación como género. A través del análisis de frases léxicas se llega a conclusiones sobre algunas de las características que definen la lengua que se usa en este tipo de textos y se comparan los resultados obtenidos con otros previos sobre el discurso escrito y el conversacional. Aunque la hipótesis de partida es que los artículos de los blogs son básicamente transaccionales, donde el principal objetivo es transmitir información, los resultados llevan a conclusiones sobre la importancia de la interacción en este tipo de discurso y también apuntan a una mayor organización de la esperable en las entradas de los comentarios al artículo principal del blog.

The lexical needs of ESP students in a professional field

This paper examines two kinds of questions relating to the lexical needs of professional ESP students: (1) what range of terms and words do they need help with? (2) what types of dictionary, bilingual and/or monolingual, can they make use of in solving lexical problems?

Neural basis of lexical-semantic processing and integration of symbolic gestures with words

Three studies investigated the relation between symbolic gestures and words, aiming at discover the neural basis and behavioural features of the lexical semantic processing and integration of the two communicative signals. The first study aimed at determining whether elaboration of communicative signals (symbolic gestures and words) is always accompanied by integration with each other and, if present, this integration can be considered in support of the existence of a same control mechanism. Experiment 1 aimed at determining whether and how gesture is integrated with word. Participants were administered with a semantic priming paradigm with a lexical decision task and pronounced a target word, which was preceded by a meaningful or meaningless prime gesture. When meaningful, the gesture could be either congruent or incongruent with word meaning. Duration of prime presentation (100, 250, 400 ms) randomly varied. Voice spectra, lip kinematics, and time to response were recorded and analyzed. Formant 1 of voice spectra, and mean velocity in lip kinematics increased when the prime was meaningful and congruent with the word, as compared to meaningless gesture. In other words, parameters of voice and movement were magnified by congruence, but this occurred only when prime duration was 250 ms. Time to response to meaningful gesture was shorter in the condition of congruence compared to incongruence. Experiment 2 aimed at determining whether the mechanism of integration of a prime word with a target word is similar to that of a prime gesture with a target word. Formant 1 of the target word increased when word prime was meaningful and congruent, as compared to meaningless congruent prime. Increase was, however, present for whatever prime word duration. In the second study, experiment 3 aimed at determining whether symbolic prime gesture comprehension makes use of motor simulation. Transcranial Magnetic Stimulation was delivered to left primary motor cortex 100, 250, 500 ms after prime gesture presentation. Motor Evoked Potential of First Dorsal Interosseus increased when stimulation occurred 100 ms post-stimulus. Thus, gesture was understood within 100ms and integrated with the target word within 250 ms. Experiment 4 excluded any hand motor simulation in order to comprehend prime word. The effect of the prior presentation of a symbolic gesture on congruent target word processing was investigated in study 3. In experiment 5, symbolic gestures were presented as primes, followed by semantically congruent target word or pseudowords. In this case, lexical-semantic decision was accompanied by a motor simulation at 100ms after the onset of the verbal stimuli. Summing up, the same type of integration with a word was present for both prime gesture and word. It was probably subsequent to understanding of the signal, which used motor simulation for gesture and direct access to semantics for words. However, gesture and words could be understood at the same motor level through simulation if words were preceded by an adequate gestural context. Results are discussed in the prospective of a continuum between transitive actions and emblems, in parallelism with language; the grounded/symbolic content of the different signals evidences relation between sensorimotor and linguistic systems, which could interact at different levels.

Estudo semântico-lexical do códice oitocentista Memoria sobre o Plano de Guerra Offensiva e Deffensiva da Capitania de Matto Grosso

Esta tese, com o intuito de contribuir para uma reflexão em torno da história da formação da língua portuguesa no Brasil, propõe como objetivo geral realizar um estudo do léxico no município de Cáceres-MT, tendo como base a discussão sobre manutenção, tendência à manutenção, desuso, tendência ao desuso e neologismo semântico de unidades lexicais extraídas de um manuscrito oitocentista. Os objetivos específicos são os seguintes: (i) compreender a história social da Capitania de Mato Grosso e do município de Cáceres, a partir das informações constantes no manuscrito Memoria, e aspectos que envolvam as condições de produção do documento e a biografia do autor; (ii) levantar o léxico do manuscrito, com recorte nos substantivos e adjetivos para servir de base na seleção das unidades lexicais a serem testadas in loco, e investigar a acepção registrada no documento das unidades lexicais, caracterizando, assim, o léxico do período oitocentista; (iii), fazer um cotejo lexicográfico abrangendo dicionários gerais dos séculos XVIII ao XXI; (iv) testar e identificar, a partir do corpus oral constituído por meio de pesquisa de campo na região urbana cacerense, o grau de manutenção, tendência à manutenção, desuso, tendência ao desuso e neologismo semântico em relação às unidades lexicais e suas respectivas acepções registradas no manuscrito. Dessa forma, toma-se como corpus de língua escrita de análise o manuscrito oitocentista Memoria sobre o plano de guerra offensiva e deffensiva da Capitania de Matto Grosso e, a partir das unidades lexicais selecionadas e extraídas dele, realizou-se a pesquisa de campo para o recolhimento do corpus de língua oral. Antes dessa recolha, tendo como base teórico-metodológica as disciplinas de Dialetologia e de Geolinguística, selecionou-se a localidade (município de Cáceres - MT) e os informantes (total de dezesseis); elaborou-se o questionário semântico-lexical, considerando fundamentalmente a proposta apresentada pelo Comitê Nacional do Projeto ALiB (2001); e realizou-se a pesquisa de campo e as transcrições das entrevistas. Para análise de natureza semântico-lexical dos corpora, recorreu aos estudos lexicográficos e lexicológicos. Tomando por base os resultados do estudo realizado, constatou-se que na realidade linguística do informante cacerense encontram-se unidades que já integravam o léxico oitocentista da língua portuguesa escrita no Brasil, ou seja, há uma memória semântico-lexical que se mantém no sistema lexical, provavelmente, devido às condições sócioculturais do município de Cáceres, Mato Grosso, cuja população, em grande parte, por quase duzentos anos, viveu na área rural. Todavia, vislumbrou-se um certo equilíbrio entre a manutenção do léxico oitocentista sem deixar de lado a inovação e o mecanismo polissêmico constitutivo do léxico.

Social Changes Reflected in Specialized Languages: Lexical Re-/deconstruction in Lesbian Studies

One of the most important factors of recognition, belonging and identification in scientific communities is their specialized language: doctors, mathematicians and anthropologists feel they are part of a group with which they can interact because they share a common “language”. While ideology is present in all academic registers, it is in human sciences where its presence (or absence) leads to more visible linguistic phenomena. An interesting example is that of lesbian studies: as non-heterosexual members of society have become less stigmatized, lesbian studies have developed a language of their own. In our paper, we shall explore the mechanisms used in the creation of specific vocabulary in this academic area, paying special attention to the refashioning or deconstruction of meaning of established terms as a result of changes in social perception or the challenging of pre-determined meanings.

Meaning selection and the subcortex: Evidence of reduced lexical ambiguity repetition effects following subcortical lesions

Recent research indicates that individuals with nonthalamic subcortical (NS) lesions call experience difficulties processing lexical ambiguities in a variety of contexts. This study examined how prior processing of a lexical ambiguity influences subsequent meaning activation in 10 individuals with NS lesions and 10 matched healthy controls. Subjects made speeded lexical decisions oil related or unrelated targets following homophone primes. Homophones were repealed with different targets biasing the same or different meanings oil the second presentation. The effects of prime-target relatedness, interstimulus interval (200 or 1250 ms), and same vs different meaning repetition were examined Both the patient and control groups showed printing when the same homophone meaning was biased oil repetition. When a different meaning was biased on the second presentation. no priming was evident in the controls, while facilitation remained present for the NS group, consistent with aberrant meaning selection and deactivation processes. These findings are discussed in terms of age and task-related repetition effects and current conceptions of frontal-subcortical involvement in cognition.

Testing the protracted lexical restructuring hypothesis: The effects of position and acoustic-phonetic clarity on sensitivity to mispronunciations in children and adults

Although developmental increases in the size of the position effect within a mispronunciation detection task have been interpreted as consistent with a view of the lexical restructuring process as protracted, the position effect itself might not be reliable. The current research examined the effects of position and clarity of acoustic-phonetic information on sensitivity to mispronounced onsets in 5- and 6-year-olds and adults. Both children and adults showed a position effect only when mispronunciations also differed in the amount of relevant acoustic-phonetic information. Adults' sensitivity to mispronounced second-syllable onsets also reflected the availability of acoustic-phonetic information. The implications of these findings are discussed in relation to the lexical restructuring hypothesis. (c) 2006 Elsevier Inc. All rights reserved.
