Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

Grammatical agreement phenomena such as verbal number have long been of fundamental interest in the study of second language (L2) acquisition. Previous research from the perspective of sentence processing has documented nativelike behavior among nonnative participants but has also relied almost exclusively on grammar violation paradigms. The…
