Resumen de The development of bilingual proficiency—A sequential analysis

Jesper Hansen

• Codeswitching is in the following analyzed as an indication of bilingual proficiency level. By applying Auer's sequential approach to codeswitching data from a longitudinal study of a Danish-Turkish bilingual setting I establish an(implicational) hierarchy of codeswitching types. The hierarchical relations between the different types are correlated with the monolingual aspect of the informants' integrated bilingual competencies. The correlation between the development of codeswitching and the development of L2 Danish paves the way for establishing a needed method of determining relative bilingual competence. I show that the way in which the codeswitching is utilized by the informants is finely attuned to the individual's linguistic proficiency.
