Code-switching (CS) is central to many bilingual communities and, though linguistic and sociolinguistic research has characterised different types of code-switches (alternations, insertions, dense CS)

• Code switching and code mixing as a communicative strategy in multilingual discourse (1989) · doi

  ABSTRACT: While the formal characteristics of codes switching and mixing, such as free morpheme constraints and equivalence constraints, have been well documented accross aa varity of languages, relatively little is known about how codw switching and mixing are used as communicative strategies in a multilingual community.

• Chinese‐English code‐mixing: a case of matrix language assignment (1991) · doi

  ABSTRACT: While it has been shown that bilingual code‐mixing (CM) is not random and that there exist rules that determine what code‐mixes are or are not allowed in bilingual speech, it has not been established yet whether the rules in question ‘come’ predominantly from one language, the matrix language, or whether they are evenly contributed by each of the languages participating in CM.

  Code-switching (CS) is central to many bilingual communities and, though linguistic and sociolinguistic research has characterised different types of code-switches (alternations, insertions, dense CS), the cognitive control processes (CPs) that mediate them are not well understood.
