Semantics and morphosyntax in predictive L2 sentence processing

In the context of current approaches to anticipation in native and non-native sentence processing, this paper investigates whether late second-language (L2) learners integrate morphosyntax, i.e. case marking, and verb semantics to generate anticipations in L2 sentence comprehension. In a visual-world eye-tracking experiment with 45 L1 English L2 learners of German and 12 German natives, German natives are found to integrate morphosyntactic and lexical-semantic information in anticipatory processing, while L2 learners only rely on lexical-semantic information for prediction. Moreover, there is no indication that increasing proficiency leads to the involvement of morphosyntax in predictive L2 processing. We discuss reasons for the lower sensitivity to morphosyntax in anticipatory L2 sentence processing.
