A comparative study of the cognitive load of basic-level category, superordinate category and subordinate category.

Abstract

Some cognitive linguists (Rosch et al. Cognit Psychol 8:382-439, 1976; Ungerer and Schmid An introduction to cognitive linguistics, Pearson Education Limited, London, England, 2006) believe the basic level category has cognitive economy because the basic level category allows obtaining the maximum amount of information about an item with the lowest cognitive effort. Whether it is also true for L2 learners has not been verified so far. This study examined whether Chinese English learners' cognitive load of basic level category is lower than that of superordinate category and subordinate category. The eye movement data, including that of total duration of fixations, total number of fixations, duration of first fixation, and average duration of fixations, generated by 31 Chinese English learners while reading sentences with different levels of category words, were collected and analyzed. The results showed that Chinese English learners' cognitive load of the basic level category was the lowest. This study provides cross-linguistic experimental evidence for the basic level category theory, and also shows the cognitive economy of basic level categories is an intrinsic psychological property, no matter whether it is the first language or the second language that the readers use.
