We investigate L1 Italian-L2 English speakers using three types of subject raising constructions: Raising over lexical DPs, pronominal DPs, and topicalizations. We test locality constraints in L2 English, including how intervention effects affect the L2 processing of A-dependencies and whether exceptionality to certain locality constraints are learnable. Three main findings emerged: (i) L2 speakers are sensitive to intervention, yet exceptions to locality can be learned; (ii) intervening DPs elicited higher processing loads only for native controls; (iii) raising with topicalizations facilitated processing only for native speakers, even though topicalization is grammatical in the L2er’s L1. Results indicate that native and non-native grammars eventually converge, exceptionality to universal constraints is learnable, and differences between native and non-native speakers lies primarily in processing.
