Motion event categorisation in a nativised variety of South African English

The present study seeks to expand the current focus on acquisition situations in linguistic relativity research by exploring the effects of nativisation (the process by which a L2 is acquired as a L1) on language-specific cognitive behaviour. Categorisation preferences of goal-oriented motion events were investigated in South African speakers who learnt English as a L1 from caregivers who spoke English as a L2 and Afrikaans as a L1. The aim of the study was to establish whether the categorisation patterns found in the nativised English variety: (1) resemble patterns of L2 speakers of English with Afrikaans as a L1, (2) resemble patterns of L1 English speakers of a non-nativised English variety and (3) do not pattern with either of the above, but instead exhibit a distinct behaviour. It was found that simultaneous, functional bilinguals (Afrikaans and nativised English) patterned with L1 Afrikaans speakers, but the extent to which they did so was modulated by their frequency of use of Afrikaans. Functionally monolingual speakers of nativised English, on the other hand, patterned with L1 speakers of British English. This suggests that bilingualism, rather than nativisation, was a reliable predictor of event categorisation preferences.
