Code-mixing is a phenomenon of bilingual children; the way and the
rate of code-mixing have aroused the interest of many scholars. There are
two main
factors that affect the rate of code-mixing: language dominance and
input. In this study, we have recorded the conversations between a Cantonese-English
bilingual child and the interlocutors. After eliminating some useless
data, we have used the CLAN program to interpret the data and see whether
it matches our prediction that a Cantonese-dominant child would show a
higher rate of mixing in English than in Cantonese. The result is only
partially consistent with our hypothesis. Dominance showed some effect
on code-mixing and switching.
