Atypical language organization in temporal lobe epilepsy revealed by a passive semantic paradigm

Background Mesial temporal lobe epilepsy (MTLE) is the most common type of focal epilepsy in adults and can be successfully cured by surgery. One of the main complications of this surgery however is a decline in language abilities. The magnitude of this decline is related to the degree of language lateralization to the left hemisphere. Most fMRI paradigms used to determine language dominance in epileptic populations have used active language tasks. Sometimes, these paradigms are too complex and may result in patient underperformance. Only a few studies have used purely passive tasks, such as listening to standard speech. Methods In the present study we characterized language lateralization in patients with MTLE using a rapid and passive semantic language task. We used functional magnetic resonance imaging (fMRI) to study 23 patients [12 with Left (LMTLE), 11 with Right mesial temporal lobe epilepsy (RMTLE)] and 19 healthy right-handed controls using a 6 minute long semantic task in which subjects passively listened to groups of sentences (SEN) and pseudo sentences (PSEN). A lateralization index (LI) was computed using a priori regions of interest of the temporal lobe. Results The LI for the significant contrasts produced activations for all participants in both temporal lobes. 81.8% of RMTLE patients and 79% of healthy individuals had a bilateral language representation for this particular task. However, 50% of LMTLE patients presented an atypical right hemispheric dominance in the LI. More importantly, the degree of right lateralization in LMTLE patients was correlated with the age of epilepsy onset. Conclusions The simple, rapid, non-collaboration dependent, passive task described in this study, produces a robust activation in the temporal lobe in both patients and controls and is capable of illustrating a pattern of atypical language organization for LMTLE patients. Furthermore, we observed that the atypical right-lateralization patterns in LMTLE patients was associated to earlier age at epilepsy onset. These results are in line with the idea that early onset of epileptic activity is associated to larger neuroplastic changes.

Translations and Translators of English-language Literature in Catalan Literary Publications and Series between 1868 and 1910

Translations into Catalan of English and American authors during the final quarter of the nineteenth century are few and far between. Numerically, English-language literature most likely ranks fifth or sixth among all the translations of this period. We take inventory here of translations found in Catalan magazines from this time (the oldest dates from 1868) and in published series that came out at this time (if these continued until later, we trace them up to their final year). At the same time, the translators are examined, including reference, where available, as to whether the translations are direct or indirect. Finally, we consider some possible causes for the low English-language volume in Catalan translation during the period.

Language extinction and linguistic fronts

Language diversity has become greatly endangered in the past centuries owing to processes of language shift from indigenous languages to other languages that are seen as socially and economically more advantageous, resulting in the death or doom of minority languages. In this paper, we define a new language competition model that can describe the historical decline of minority languages in competition with more advantageous languages. We then implement this non-spatial model as an interaction term in a reactiondiffusion system to model the evolution of the two competing languages. We use the results to estimate the speed at which the more advantageous language spreads geographically, resulting in the shrinkage of the area of dominance of the minority language. We compare the results from our model with the observed retreat in the area of influence of the Welsh language in the UK, obtaining a good agreement between the model and the observed data

Language Learning in Task Management and Task Accomplishment

In this paper we study student interaction in English and Swedish courses at a Finnish university. We focus on language choices made in task-related activities in small group interaction. Our research interests arose from the change in the teaching curriculum, in which content and language courses were integrated at Tampere University of Technology in 2013. Using conversation analysis, we analysed groups of 4-5 students who worked collaboratively on a task via a video conference programme. The results show how language alternation has different functions in 1) situations where students orient to managing the task, e.g., in transitions into task, or where they orient to technical problems, and 2) situations where students accomplish the task. With the results, we aim to show how language alternation can provide interactional opportunities for language learning. The findings will be useful in designing tasks in the future.

Content and Language Integration as a part of a degree reform at Tampere University of Technology

Tampere University of Technology is undergoing a degree reform that started in 2013. One of the major changes in the reform was the integration of compulsory Finnish, Swedish and English language courses to substance courses at the bachelor level. The integration of content and language courses aims at higher quality language learning, more fluency in studies, and increased motivation toward language studies. In addition, integration is an opportunity to optimize the use of resources and to offer courses that are more tailored to the students' field of study and to the skills needed in working life. The reform also aims to increase and develop co-operation between different departments at the university and to develop scientific follow up. This paper gives an overview of the integration process conducted at TUT and gives examples of adjunct CLIL implementations in three different languages.

The application of communicative language teaching : a particular case in a polish primary school

L’objectiu d’aquest estudi és examinar si l’Ensenyament Comunicatiu de la Llengua és usat per les mestres quan duen a terme classes d’anglès com a llengua estrangera en una escola de primària polonesa, amb un context educatiu especial. Aquesta recerca qualitativa analitza cinc conjunts principals d’informació relacionats amb l’ensenyament de la llengua estrangera que caracteritzen l’enfocament de l’Ensenyament Comunicatiu de la Llengua i que estan centrats en: el coneixement i les creences dels mestres sobre l’enfocament de l’Ensenyament Comunicatiu de la Llengua; l’ús de la llengua; els aspectes de la llengua anglesa que s’ensenyen; les característiques de les activitats: i el procés d’ensenyament. Per aquest objectiu, s’ha proporcionat un qüestionari a cada mestra d’anglès i s’han portat a terme algunes observacions d’aula per tal de recollir dades, analitzar-les i extreure’n unes conclusions. Els resultats de la investigació mostren que les mestres d’anglès donen bastant suport a l’enfocament de l’Ensenyament Comunicatiu de la Llengua, així com apliquen força sovint els seus trets característics quan porten a terme les classes.

Front Speed of Language Replacement

We use two coupled equations to analyze the space-time dynamics of two interacting languages. Firstly, we introduce a cohabitation model, which is more appropriate for human populations than classical (non-cohabitation) models. Secondly, using numerical simulations we nd the front speed of a new language spreading into a region where another language was previously used. Thirdly, for a special case we derive an analytical formula that makes it possible to check the validity of our numerical simulations. Finally, as an example, we nd that the observed front speed for the spread of the English language into Wales in the period 1961-1981 is consistent with the model predictions. We also nd that the e¤ects of linguistic parameters are much more important than those of parameters related to population dispersal and reproduction. If the initial population densities of both languages are similar, they have no e¤ect on the front speed. We outline the potential of the new model to analyze relationships between language replacement and genetic replacement

Facilitar la teoría de la mente en niños con alteraciones del lenguaje

The ability to recognize mental states in oneself and others, or the theory of mind, has been a widely studied topic in last years. Traditionally, these studies have focused on the understanding of false belief, one of the most important milestones in its development. Studies conducted with children with language difficulties suggest that they have a delay in false belief acquisition. On the other hand, numerous studies have established a relationship between the understanding of false belief and language skills. In particular, it has been suggested that training based in labelling objects with double perspective facilitates the understanding of false belief. The aim of the present study is to test the effect of the structuration level of labelling training in a group of children with difficulties in language development. A total of 14 children, aged between 58 and 107 months, were trained in 3 sessions, and a pre-test and a post-test were administered to evaluate the effects of the training. The results confirm a delay in false belief understanding in children with developmental language difficulties, and suggest that the structured labelling training is effective to improve this understanding

La Relación del lenguaje con la teoría de la mente en edad escolar

In the past years a considerable amount of research has been carried out on the development of theory of mind (ToM) reporting that language and ToM performance are correlated. However it is less clear what aspect of language is related with ToM development. Some studies show a greater influence of semantics aspects, whereas others suggest that sentential complement sentences, a specific aspect of syntax, are crucial for false belief understanding (FB). Yet others argue that pragmatic abilities correlate with FB understanding. The aim of this study is investigate, on the one side, the development of ToM between the ages of 6 and 8 and on the other side, the relationship between some aspects of language and the ToM improvement. Several ToM tasks were administrated to evaluate children’s performance at two different ages (60 participants aged 6 and 8 years) and four tasks to assess language abilities. The results show a significant increase in the understanding of the mind between the ages of 6 and 8. Furthermore, results reveal a significant relationship between syntax and tasks that require FB understanding, while pragmatics is more strongly associated with tasks that involve more complex socio-cognitive understandings

Individual differences in control of language interference in late bilinguals are mainly related to general executive abilities

Background: Recent research based on comparisons between bilinguals and monolinguals postulates that bilingualism enhances cognitive control functions, because the parallel activation of languages necessitates control of interference. In a novel approach we investigated two groups of bilinguals, distinguished by their susceptibility to cross-language interference, asking whether bilinguals with strong language control abilities ('non-switchers") have an advantage in executive functions (inhibition of irrelevant information, problem solving, planning efficiency, generative fluency and self-monitoring) compared to those bilinguals showing weaker language control abilities ('switchers"). Methods: 29 late bilinguals (21 women) were evaluated using various cognitive control neuropsychological tests [e.g., Tower of Hanoi, Ruff Figural Fluency Task, Divided Attention, Go/noGo] tapping executive functions as well as four subtests of the Wechsler Adult Intelligence Scale. The analysis involved t-tests (two independent samples). Non-switchers (n = 16) were distinguished from switchers (n = 13) by their performance observed in a bilingual picture-naming task. Results: The non-switcher group demonstrated a better performance on the Tower of Hanoi and Ruff Figural Fluency task, faster reaction time in a Go/noGo and Divided Attention task, and produced significantly fewer errors in the Tower of Hanoi, Go/noGo, and Divided Attention tasks when compared to the switchers. Non-switchers performed significantly better on two verbal subtests of the Wechsler Adult Intelligence Scale (Information and Similarity), but not on the Performance subtests (Picture Completion, Block Design). Conclusions: The present results suggest that bilinguals with stronger language control have indeed a cognitive advantage in the administered tests involving executive functions, in particular inhibition, self-monitoring, problem solving, and generative fluency, and in two of the intelligence tests. What remains unclear is the direction of the relationship between executive functions and language control abilities.

Desde los actos de habla de Austin a los actos comunicativos. Perspectivas desde Searle, Habermas y CREA

El concepto de acto de habla ha sido una gran aportación de la filosofía del lenguaje al estudio de los procesos de comunicación que está tomando mayor importancia con el actual giro dialógico de las sociedades y las propias ciencias sociales. El desarrollo posterior que hizo Searle de las contribuciones de Austin fue tomado como el punto de partida de la concepción de actos de habla y actos comunicativos que Ha-bermas consideró una de las bases de su teoría de la acción comunicativa. Sin embargo, en el trabajo conjunto de Searle y CREA se clarificaron los errores de comprensión que Habermas tuvo de la concepción de Searle. De ese debate surgió la importancia del desarrollo de la concepción de actos comunicativos dialógicos y actos comunicativos de poder que ha sido incorporada al proyecto INCLuD-ED1 cuyo equipo ha continuado desarrollándola hasta la actualidad en diferentes ámbitos. En este artículo se desarrolla esa evolución a partir de un análisis de las aportaciones recientes de la filosofía del lenguaje, seguidamente de una explicación de los actos de habla y los actos comunicativos y finalmente un análisis de las relaciones de poder y las relaciones dialógicas que se dan en los diferentes actos comunicativos.

Is there a relationship between bilingual language switching and executive functions in bilingualism? Introducing a within-group analysis approach

Several studies have suggested a bilingual advantage in executive functions, presumably due to bilinguals' massive practice with language switching that requires executive resources, but the results are still somewhat controversial. Previous studies are also plagued by the inherent limitations of a natural groups design where the participant groups are bound to differ in many ways in addition to the variable used to classify them. In an attempt to introduce a complementary analysis approach, we employed multiple regression to study whether the performance of 30- to 75-year-old FinnishSwedish bilinguals (N = 38) on tasks measuring different executive functions (inhibition, updating, and set shifting) could be predicted by the frequency of language switches in everyday life (as measured by a language switching questionnaire), L2 age of acquisition, or by the self-estimated degree of use of both languages in everyday life. Most consistent effects were found for the set shifting task where a higher rate of everyday language switches was related to a smaller mixing cost in errors. Mixing cost is thought to reflect top-down management of competing task sets, thus resembling the bilingual situation where decisions of which language to use has to be made in each conversation. These findings provide additional support to the idea that some executive functions in bilinguals are affected by a lifelong experience in language switching and, perhaps even more importantly, suggest a complementary approach to the study of this issue.
