Syntactic Complexity Measures as Indices of Language Proficiency in Writing: Focus on Heritage Learners of Russian

Abstract

Abstract The concept of linguistic complexity, understood broadly as a range of basic and elaborate structures available and accessible to learners as evidenced in their production of speech and writing (Ortega, 2003), has featured prominently in second language development research since the inception of the field. The field of heritage language acquisition, however, has only recently begun to engage linguistic complexity as a comprehensive lens for studying heritage language development. The current study contributes to this fledgling area of research by investigating automatically extracted measures of syntactic complexity in the written language of heritage learners of Russian at various developmental levels. The analysis of 12 measures of syntactic complexity allows us to conclude that the majority of automatically extracted indices differentiate proficiency levels of heritage speakers in the study. The study results provide important insights into the nature of heritage language development and are readily applicable for assessment and pedagogical purposes.
