LEXICAL COMPETENCE UNDERLYING SECOND LANGUAGE WORD ASSOCIATION TASKS
EXAMINING THE CONSTRUCT VALIDITY OF RESPONSE TYPE AND RESPONSE TIME MEASURES
Published online by Cambridge University Press: 16 June 2021
Abstract
This study investigated the constructs underlying second language (L2) word association (WA) with regard to three dimensions of lexical competence—size, organization, and accessibility—and the lexical performance of speech. One-hundred and thirteen Japanese learners of English completed a computer-delivered oral WA task along with three vocabulary tasks: a form-recall gap-filling task (size), a primed lexical decision task (organization and accessibility), and an oral cartoon narrative (lexical richness). Regression analyses explored how well these lexical competence and performance scores predicted two WA outcome variables: response profiles and response times. Form-recall vocabulary knowledge, (collocational) priming, and lexical richness explained a large amount of variance in WA response type profiles (Nagelkerke’s pseudo R2 = .901). Form-recall vocabulary knowledge and lexical decision time explained 28.5% of the variance of WA response times. A three-stage model of L2 WA task performance is proposed to account for the constructs underlying WA performance.
