There is a fairly long history in the studies of Second Language Acquisition and particularly in the field of Language Transfer (LT) as an inevitable phenomenon (Odlin, 1989). Most literatures thus far complied with a certain procedure in its study of LT, however, this is not without its limitations. Meanwhile, LT, particularly negative LT (-LT), may benefit from the application of Vygotsky’s Sociocultural Theory of the Zone of Proximal Development (ZPD) and Scaffolding. The present paper reviews -LT literatures and suggests an integration with ZPD and Scaffolding to its study.
