Syntactic prediction in L2 learners: evidence from English disjunction processing

This study examined the extent to which second language (L2) learners’ syntactic prediction resembles or differs from native speakers’ and the role of L2 proficiency in this process. An experimental group of 135 Chinese learners of English and a control group of 58 English native speakers participated in a phrase-by-phrase self-paced reading task where the experimental sentences were contrastive in whether the DP disjunction was preceded by either or not. To ensure that the participants had sufficient knowledge about the target stimuli, they were asked to additionally judge the acceptability of the experimental sentences. The results showed that like native speakers, L2 learners read the critical region consisting of “or” and a DP disjunct faster when it was preceded by either compared to when either was absent. In addition, this effect of the presence versus absence of either spilled over to the post-critical region. Moreover, L2 proficiency was not found to robustly modulate this process. It is concluded that L2 learners, like native speakers, can make predictions at the level of syntax.
