Sensitivity to parasitic gaps inside subject islands in native and non-native sentence processing

Abstract

We report the results from an eye-movement monitoring study that investigated late German–English bilinguals’ sensitivity to parasitic gaps inside subject islands. The online reading experiment was complemented by an offline scalar judgement task. The results from the offline task confirmed that for both native and non-native speakers, subject island environments must normally be non-finite in order to host a parasitic gap. The analysis of the reading-time data showed that, while native speakers posited parasitic gaps in non-finite environments only, the non-native group initially overgenerated parasitic gaps, showing delayed sensitivity to island-inducing cues during online processing. Taken together, our findings show that non-native comprehenders are sensitive to exceptions to island constraints that are not attested in their native language and also rare in the L2 input. They need more time than native comprehenders to compute the linguistic representations over which the relevant restrictions are defined, however.
