1) The study used ERPs to examine brain responses to verbs violating either lexical-semantic constraints or constraints specified by a syntactic construction in Chinese sentences.
2) Lexical-semantic violations elicited a widespread N400 effect, while construction violations produced a more posterior N400 effect.
3) The findings provide online evidence that sentence comprehension is influenced not only by lexical semantics but also by the abstract meanings of syntactic constructions, supporting construction grammar theories.
