Since the Shallow Structure Hypothesis (SSH) was first put forward in 2006, it has inspired a growing body of research on grammatical processing in nonnative (L2) speakers. More than 10 years later, we think it is time for the SSH to be reconsidered in the light of new empirical findings and current theoretical assumptions about human language…

Compares different approaches to first- and second-language development. It is argued that the observed differences between first- and (adult) second-language acquisition can be accounted for by assuming that adult second-language learners can not use Universal Grammar principles as a learning device in the same way that first-language learners…

Suggests that differences between first- and second-language learners are due to principles of universal grammar (UG) that guide first language (L1), but not second language (L2) acquisition. This view can be reconciled with the idea that L2 learners can use UG principles to some extent in evaluating target sentences. (49 references) (Author/VWL)

Four groups of second language (L2) learners of English from different language backgrounds (Chinese, Japanese, German, and Greek) and a group of native speaker controls participated in an online reading time experiment with sentences involving long-distance "wh"-dependencies. Although the native speakers showed evidence of making use of…
