Second language (L2) learners whose first language (L1) does not
morphologically mark agreement tend to experience difficulties during
online processing. This study attempts to show sensitivity to agreement
violations may dwindle as a function of cognitive resources and structural
complexity, manipulated by distance. Our predictions were based on the
cross-linguistic
competition account, positing processing variability may arise when
grammatical patterns licensed by the learners’ L1 compete with those
licensed by L2 for selection. The results from self-paced reading suggested
structural complexity as well as cognitive resources may play a role in L2
learners’ ability to display sensitivity to morphosyntactic violations.
