Exploring the impact of individual differences in aural vocabulary knowledge, written vocabulary knowledge and working memory capacity on explaining L2 learners’ listening comprehension

Abstract

Abstract Listening comprehension constitutes a considerable challenge for second language learners, but little is known about the relative contribution of individual differences in distinct factors to listening comprehension. Since research in this area is relatively limited in comparison to that focusing on the relationship between reading comprehension and factors such as vocabulary knowledge and working memory, there is a need for studies that seek to fill the gap in our knowledge about the specific contribution of aural vocabulary knowledge, written vocabulary knowledge and working memory capacity to explaining listening comprehension. Among 130 non-native speakers of English, the present study examines what proportion of the variance in listening comprehension is explained by aural vocabulary knowledge, written vocabulary knowledge, and working memory capacity. The results show that aural vocabulary knowledge is the strongest predictor of listening comprehension, followed by working memory capacity, while written vocabulary knowledge contributes only marginally. The study discusses implications for the explanatory power of aural vocabulary knowledge and working memory to listening comprehension and pedagogical practice in second language classrooms.
