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…

Students' grasp of the non-mathematical language in a mathematics story problem--such as vocabulary and syntax--may have an important effect on their problem-solving, and this may be particularly true for students with weaker language skills. However, little experimental research has examined which individual language features influence students'…

A pervasive question in second language (L2) research is whether L2 learners can acquire parameterized functional features that are not instantiated in their first language (L1). While some researchers have argued for a representational deficit (e.g., Clahsen & Muysken, 1989; Hawkins & Chan, 1997), claiming that L2 learners' competence is…

Different genres of writing entail various levels of syntactic and lexical complexity, and how this complexity influences the results of Automatic Writing Evaluation (AWE) programs like Grammarly in second language (L2) writing is unknown. This study explored the use of Grammarly in the L2 writing context by comparing error frequency, error types…

There has been considerable progress in second language (L2) research at the syntax-semantics interface addressing how syntax can inform phrasal semantics, in terms of interpretive correlates of word order (Slabakova, 2008). This article provides evidence of a flow of information ostensibly in the opposite direction, from meaning to grammar, at…
