Effects of Involvement Load of the Task on Japanese EFL Learners’ Lexical Network Changes


This study investigated the effects of task-induced involvement load (the Involvement Load Hypothesis; Laufer & Hulstijn, 2001), Search and Evaluation in particular, in an extensive reading on a change of lexical network perceived by EFL learners. Fifteen words from a reading material were chosen as target words. Ninety-five Japanese university students were divided into four groups resulting from a multiplication of Search (+/-) and Evaluation (+/-). Evaluation (+) groups were assigned a partial translation task of the passage. Evaluation (-) groups were assigned multiple-choice questions about its contents. Search (+) groups were allowed to use dictionaries, whereas Search (-) groups were not. Participants judged a perceived relation between target words three times, a week before the task, immediately after the task, and three weeks after the task. The results showed that differences of involvement index among the four groups did not affect the perceived relation among target words, though the effect of extensive reading itself (with any accompanying task) was confirmed. Data was also analyzed and visualized by Gephi, a data-visualization platform, to show how participant’s lexical network changed through the three tests. As a result, some qualitative features of individual’s network change were revealed, which shows the importance of investigating individual differences as well as group data. The present findings raised new research questions; if the task-induced involvement load does not work for the lexical network change of already-known words, and if there are any involvement components other than Need, Search, and Evaluation to be considered.
