Keijzer (2007) conducts a study on the L1 attrition of Dutch in anglophone Canada. Her study compares language acquisition in children with non-pathological language attrition found in emigrant populations and contrasts it with language use in non-attrited, mature speakers. In particular, it examines the parallels and divergences between advanced stages of L1 Dutch acquisition (in adolescents) and the L1 attrition of Dutch émigrés in Anglophone Canada, as opposed to control subjects. She finds some evidence that later-learned rules, for example with respect to diminutive and plural formation, do indeed erode before the earlier learned information. However, there is also considerable interaction between the first and second language, so a straightforward 'regression pattern' cannot be observed.
