Bidirectional transfer takes place in bilingualism. For this reason, bidirectionality, proposed by Pavlenko(2000) and Pavlenko & Jarvis(2002), should be discussed under the multicompetence framework, under which ``people who know more than one language have a distinct compound state of mind that is not equivalent to two monolingual state``(Cook 1991, 1992). Based on the concepts of bidirectionality, bilingualism and multicompetence, this study reanalyzes the work of Lee(2010) trying to find evidences of pragmatic transfer in refusal strategies and finds out that L2 influence on L1 really happens in a pragmatic aspect. In addition, in biculturalism, this study suggests the reason why native Americans follow the Korean pragmatic rules, not their pragmatic ones when they produce their language.
