The role of n-back task and statistical learning in L2 sentence processing

Abstract

This study investigates the role of working memory and statistical learning ability in L2 sentence processing. A total of 26 native-Korean-speaking L2 learners of English completed three tasks: (a) an n-back task, as a measure of working memory; (b) an artificial grammar learning task containing a nonadjacent dependency rule formed between words to test statistical learning ability; and (c) a self-paced English reading task including sentences with object relative clauses. The results show a significant relationship between participants’ working memory and their L2 sentence processing performance (r = .403), but no significant relationship between statistical learning ability and L2 sentence processing performance. The findings provide better understanding of learners’ individual differences by examining the relationships between statistical learning, working memory, and L2 sentence processing.
