Análisis de los aspectos intrínsecos y extrínsecos de la coherencia en los textos para la enseñanza del inglés académico y profesional

RESUMEN. En este artículo abordamos la evaluación de textos especializados, con fines docentes, mediante un estudio experimental basado en los rasgos de textualidad que hacen que el texto resulte coherente para sus lectores. Se comprueba, empíricamente, que existe una correlación positiva entre la adecuación del texto a los rasgos de textualidad y su comprensión por parte de los alumnos de ingeniería de Minas que han formado el grupo experimental. Queda patente cómo textos que en un primer análisis se pudiera afirmar que cumplen los criterios de textualidad, aplicados a otro contexto situacional distinto de aquel para el que fueron escritos, pueden no cumplir con los mismos criterios, resultando inadecuados o no totalmente inteligibles. Se constata que la coherencia textual no depende exclusivamente de factores intratextuales, sino también de aquellos otros extratextuales relacionados con la comunidad receptora. ABSTRACT. This article deals with the evaluation of specialised texts for eduactional purposes. It reports on an experimental study based on those textuality feactures which make a text coherent to the readers. It is empirically tested that there exists a positive correlation between textuality features of a given text and its reading comprehension by engineering students participating in the experimental study. It is shown how texts, that initially comply with textuality features, taken into a different context from that for which they were written, may become inadequate or even non understandable. It becomes evident that textual coherence does not depend exclusively on intratextual elements but on those extratextual ones related to the receiving community as well.

Conflict and cognitive control during sentence comprehension: recruitment of a frontal network during the processing of Spanish object-first sentences.

During sentence processing there is a preference to treat the first noun phrase found as the subject and agent, unless marked the other way. This preference would lead to a conflict in thematic role assignment when the syntactic structure conforms to a non-canonical object-before-subject pattern. Left perisylvian and fronto-parietal brain networks have been found to be engaged by increased computational demands during sentence comprehension, while event-reated brain potentials have been used to study the on-line manifestation of these demands. However, evidence regarding the spatiotemporal organization of brain networks in this domain is scarce. In the current study we used Magnetoencephalography to track spatio-temporally brain activity while Spanish speakers were reading subject- and object-first cleft sentences. Both kinds of sentences remained ambiguous between a subject-first or an object-first interpretation up to the appearance of the second argument. Results show the time-modulation of a frontal network at the disambiguation point of object-first sentences. Moreover, the time windows where these effects took place have been previously related to thematic role integration (300–500 ms) and to sentence reanalysis and resolution of conflicts during processing (beyond 500 ms post-stimulus). These results point to frontal cognitive control as a putative key mechanism which may operate when a revision of the sentence structure and meaning is necessary
