Examining variability in the processing of agreement in novice learners: Evidence from event-related potentials.

摘要: The present study examines both properties of the language and learner to better understand variability at earliest stages second (L2) acquisition. We used event-related potentials, an oral production task, a battery individual differences measures examine processing number gender agreement in two groups low-proficiency English-speaking learners Spanish who were tested multiple sessions. results showed advantage for number, feature also instantiated native language, as native-like P600 response subject-verb noun-adjective violations across more advanced group larger effects marginal sensitivity violations. These suggest that shared features is possible even novice learners, contrary proposals suggesting all morphosyntactic dependencies are initially processed non-native manner. Working memory (WM) was predictor (where effect marginal), similar abilities may capture unique despite overall sensitivity. Furthermore, whereas WM predicted performance on online tasks (P600 effects/oral production), verbal aptitude examining accuracy (grammaticality judgment task/oral production). Our show linguistic L2, characteristics learner, nature task hand play important role capturing often observed L2 agreement. (PsycInfo Database Record (c) 2021 APA, rights reserved).
