“…There have been a number of studies of the acquisition of Russian as a second language (Gor et al, 2009;Hasko, 2009;Rifkin, 1995;Rosengrant, 1987;Thompson, 1997) as well as a heritage language (Andrews, 2001;Isurin & Ivanova-Sullivan, 2008;Kagan, 2001;Kagan & Dillon, 2001;Polinsky, 2000;Polinsky, 2008;Polinsky & Kagan, 2007;Romanova, 2008). These studies showed that heritage and second language learners of Russian, having very different backgrounds, often make errors in the same categories (word order, tense and aspect, case errors).…”
