comprehension of this language by the child. Kaufman and Aronoff (1991) studied a native Hebrew-speaking child having immigrated to the United States with her family at 2.5 years of age. This child, contrary to the adoptees in the present study and the Chinese girl mentioned above, continued being exposed to her L1 while acquiring L2 in the school environment. Yet, despite this continued exposure, attrition of L1 (lexical and morphological) was once again observed after only a few months in the country of immigration. Turian and Altenberg's (1991) study focused on a Russian–English bilingual child whose exposure to Russian (L1) was radically reduced at 3.5 years of age. Observation of the child's L1 conversational skills almost one year after the reduction in L1 input revealed several compensatory strategies and other elements of language attrition.
