ABSTRACT
The present study examined how working memory (WM) affects unfamiliar word processing during L2 reading comprehension among L2 learners with different proficiency levels. Forty-four participants were divided into the higher proficiency group (n = 22) and the lower proficiency group (n = 22). All of them read an English text with 17 target unfamiliar words while their eye movements were tracked. After online reading, they subsequently completed an L2 reading comprehension test and a WM test respectively. The results showed that WM significantly correlated with L2 reading comprehension in the higher proficiency group. In addition, the effect of WM capacity on L2 reading comprehension performance was mediated by unfamiliar words’ first fixation duration in the higher proficiency group. Results of the study revealed the different mechanisms of unfamiliar word processing among learners with different proficiency levels from the cognitive dimension of WM.
