Abstract:
This paper shows that L1 transfer may not be effectively maintained in the interlanguage due to confounding factors in the L2. When two factors, A and B, are correlated in the L2, second language learners may only acquire B, even if A is present in the L1. Transfer may not be effective because B, being more robust in the input, conceals A. Native speakers, on the other hand, generalize A in spite of B. The variables in question are weight-sensitivity (A) and positional bias (B) in English, both of which can predict the location of stress in the language. I show that two seemingly target-like groups of second language learners of English (speakers of Mandarin and speakers Portuguese) fail to accurately generalize weight-sensitivity in the language, and instead display response patterns which are predictable given the existing positional bias in English stress.
