title: Human neuronal encoding of English syntactic violations as revealed by both L1 and L2 speakers.
abstract: Our previous study [M. Kubota, P. Ferrari, T.P.L. Roberts, Magnetoencephalography detection of early syntactic processes in humans: comparison between L1 speakers and L2 learners, Neurosci. Lett. 353 (2003) 107-110] showed that an early syntactic response was elicited in first language (L1) speakers for within-phrase, but not across-phrase violations, implying that there may exist a continuum of neuronal error gravity. Such an early component was not elicited by second-language (L2) learners. The current auditory study investigated whether two types of different syntactic violations regarding noun-phrase raising (NP-raising) and case-filter constructions would elicit a prominent early syntactic component in each hemisphere for both L1 and advanced L2 speakers of English. Neuromagnetic fields were recorded, using a dual 37-channel gradiometer system. A prominent component, peaking at approximately 150 ms post-onset, was observed in both hemispheres of two groups in response to NP-raising induced violations, but not case-filter violations. The findings imply that L1 and L2 speakers have similar neuronal mechanisms subserving syntactic processing of such violations.
