Abstract:
Icelandic and Norwegian past tense morphology contain strong patterns of inflection and two weak patterns of inflection. We report the results of an elicitation task that tests Icelandic and Norwegian children¿s knowledge of the past tense forms of a representative sample of verbs. This cross-sectional study of four-, six- and eight-year-old Icelandic (N=92) and Norwegian (N=96) children systematically manipulates verb characteristics such as type frequency, token frequency and phonological coherence¿factors that are generally considered to have an important impact on the acquisition of inflectional morphology in other languages. Our findings confirm that these factors play an important role in the acquisition of Icelandic and Norwegian. In addition, the results indicate that the predominant source of errors in children shifts during the later stages of development from one weak verb class to the other. We conclude that these findings are consistent with the view that exemplar-based learning, whereby patterns of categorisation and generalisation are driven by similarity to known forms, appropriately characterises the acquisition of inflectional systems by Icelandic and Norwegian children.
