The Competition Model has served as a functional explanation of cross-linguistic influence and transfer for more than 30 years. A large number of studies have used the Competition Model to frame investigations of sentence processing strategies in different types of bilingual and multilingual speakers. Among the different bilingual speakers investigated, Mandarin Chinese and English bilinguals represent a clear testing ground for the claims of the Competition Model. This is because of purportedly stark contrasts in sentence processing strategies between the two languages. Previous studies investigating sentence processing strategies of English L2 and Mandarin L2 bilinguals suggests forward transfer of L1 cues to the L2, moderated by L2 proficiency. In this paper, we argue for replication of two of these studies, namely Liu, Bates, and Li (1992) and Su (2001). These studies continue to be cited today as evidence of differences between English and Mandarin sentence processing strategies which is in turn taken as support for the predictions of the Competition Model. However, both studies presented methodological limitations in terms of measures of proficiency, participant and stimuli selection, and the statistical analysis. We suggest approximate replication of both of these studies and provide suggestions for how such replications might be conducted.
