Further evidence in support of the Cumulative-Enhancement Model
The Cumulative- Enhancement Model proposed by Flynn et al. (2004) seeks to provide an explanatory model for multiple language acquisition. Results reported in this paper present further evidence in support of this model. Results of an elicited imitation task comparing the production of relative clauses by learners of German L1 and Hungarian L1/German L2 acquiring L2 and L3 English respectively at three levels of proficiency indicate, on the one hand, an increased facilitation in subsequent acquisition with each new language learned and, on the other hand, development of syntactic knowledge in L3 acquisition that cannot be explained in terms of an astructural transfer from the last language learned.
