The Influence of the Social Use and the History of Acquisition of Euskera on Comprehension and Recall of Scientific Texts in Euskera and Castilian

LANGUAGE LEARNING, Issue 3 2002
Arantxa Gorostiaga
This study examined the influence of the social use and the history of acquisition of Euskera (the Basque language) on comprehension and recall of two versions (Euskera ,Castilian) of a scientific text read by bilingual high school and college students. Comprehension was measured by performance on an inferential task and recall by efficiency on a test that assessed recognition of essential and supplementary information in the text. Results suggested that both extensive social use and an active history of acquisition of a language improve the level of comprehension of a text written in that language. However, neither factor facilitated the recognition of essential information in the text. The possible implications of these results for education are discussed. [source]

Experimental study on the extraction and distribution of textual domain keywords

CONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 16 2008
Xiangfeng Luo
Abstract Domain keywords of text play a primary role in text classifying, clustering and personalized services. This paper proposes a term frequency inverse document frequency (TFIDF) based method called TDDF (TFIDF direct document frequency of domain) to extract domain keywords from multi-texts. First, we discuss the optimal parameters of TFIDF, which are used to extract textual keywords and domain keywords. Second, TDDF is proposed to extract domain keywords from multi-texts, which takes document frequency of domain into account. Finally, the distribution of domain keywords on scientific texts is studied. Experiments and applications show that TDDF is more effective than the optimal TFIDF in the extraction of domain keywords. Domain keywords accord with normal distribution on a single text after deleting the ubiquitous domain keywords. Copyright © 2008 John Wiley & Sons, Ltd. [source]

Visuospatial memory and phonological loop in learning from multimedia

APPLIED COGNITIVE PSYCHOLOGY, Issue 6 2002
Valérie Gyselinck
The dual-task paradigm was used to show how visuospatial working memory and the phonological loop are involved in processing scientific texts and illustrations presented via computer. In experiment 1, two presentation formats were compared: text-only and text-with-illustrations. With a concurrent tapping task, the beneficial effect of illustrations disappeared, while a concurrent articulatory task impaired performance similarly in both presentation formats. An analysis of individual differences revealed that this pattern of results was present in high, but not low spatial span subjects. These results support the selective involvement of visuospatial working memory in processing illustrated texts. In Experiment 2, the text-only presentation format was compared to an illustrations-only format. The concurrent articulatory task selectively impaired text-only processing, compared with processing illustrations-only. In addition, this pattern of results was found for high, but not low digit span subjects. These results suggest that individual differences define the extent to which the two subsystems of working memory are involved in learning from multimedia. These two subsystems would be mainly involved in the maintenance of a visual trace of illustrations and of a verbatim representation of linguistic information respectively, these representations being the basis for higher-level comprehension processes.

Classifying Communibiology's Texts: Implications for Genre Theory

COMMUNICATION THEORY, Issue 2 2004
Christian K. Nelson
One can categorize communibiological texts as interdisciplinary inspirational texts. However, one can classify these texts differently with equal plausibility by attending to aspects of the social psychology and economic conditions of current science that are rarely considered by most rhetoricians of science and attending to 2 significant rhetorical requirements of successful scientific texts,programmaticality and interestingness,that have gone unnoticed by rhetoricians of science to date. Given this equality of categorization plausibility, traditional genre theories are contradicted. More significantly, through the author's provision of a reflexive analysis, pragmatist genre theory is supported and extended. Thus, this article contributes to genre theory and the rhetoric of science. [source]
