The research area Language Development & Multilingualism investigates the development of linguistic competence in different speaker groups over the entire life span. Our research focuses on the language acquisition of monolingual and multilingual children of pre-school and primary school age. One focus is on early, uncontrolled language acquisition, as it occurs in families who speak several languages at home, and controlled second language acquisition, such as through language support in kindergarten.
Based on empirical data, we present general development processes in different languages of origin and the educational language German and investigate the influence of individual living conditions such as education, social environment, etc. on language development. We investigate both lexical and grammatical language acquisition as well as the acquisition of narrative skills, which together form the basis for participating in social discourse. The researchers in this field participate in the development of tools for multilingual language surveys.
