  • When Positive Transfer is not enough in 3rd Language Acquisition, Stanford University

    Analysis of several Oral Proficiency Interviews (OPIs) of intermediate-low to intermediate-high learners of Brazilian Portuguese (BP) as a third language focused on the marking of gender agreement in noun phrases in BP. The results have shown that the learners' proficiency level in BP is a better predictor of accurate gender marking than their experience with Spanish, whether as a second language or a native language. These findings shed new light on how the teaching of third languages should be conducted and require a restructuring of how positive transfer factors into the learner's interlanguage.
