Cross-linguistic influence and language-learning aptitude in L3 acquisition of functional morphology

• Cross-linguistic influence and language-learning aptitude in L3 acquisition of functional morphologyTwo factors suggested to influence second-language acquisition are cross-linguistic influence (CLI) and language-learning aptitude. However, the relationship between the two has rarely been investigated, and it is unclear to what extent the relative importance of CLI and aptitude depends on the degree of similarity between source and target language (cf. Bokander 2021; Skehan 1998; Tolentino & Tokowicz 2014). The present study addresses this issue by examining the longitudinal development of definiteness marking in Russian-speaking learners of Swedish who had previously acquired English. Unlike Russian, English and Swedish obligatorily express definiteness using dedicated functional morphology. While the English indefinite article (a park) is structurally similar to its Swedish counterpart (en park ‘a park’), the English definite article (the park) is structurally dissimilar to its Swedish counterpart, a nominal suffix (park-en ‘the park’). This enables us to investigate the role of cross-linguistic influence and aptitude in third-language acquisition of functional morphology.Definite and indefinite noun phrases were orally elicited from native speakers of Russian (n=18) during two terms of a beginner-Swedish course. At data point 1, their use of English articles and their aptitude were also tested (Meara 2005). Further, data were collected from native speakers of Swedish (n=26) and English (n=17). The participants’ use of indefinite and definite morphemes was analysed separately. Two linear mixed-effects models revealed that the learners’ developing use of the Swedish indefinite article was associated with their command of the English indefinite article, which is structurally similar. By contrast, their developing use of the Swedish definite nominal suffix, which is structurally dissimilar to its English counterpart, was moderated primarily by aptitude. This suggests that learners may capitalise on previously acquired linguistic knowledge primarily when source and target languages are similar, while language-learning aptitude appears to play a more important role in the acquisition of qualitatively new morphology.ReferencesBokander, Lars (2021).
