My primary research interest is in the area of language disorders in children, their underlying nature, as well as assessment and therapeutic intervention. I am interested in the impact of processing capacity limitations on language learning and use, particularly in the interaction of linguistic complexity and processing capability. Some of my previous research has focused on language acquisition in Icelandic children. This research has included the development of assessment measures that facilitate clinical diagnosis as well as documentation of language level for research purposes. My current work, which continues to include a cross-linguistic component, is focused on verb learning and use by children with specific language impairment from the standpoint of a limited capacity framework.
Issues related to hearing are another area of interest.
Mean length of utterance and other language sample measures in early Icelandic. To explore these issues, I conduct experimental research into unconscious and abstract syntactic properties in the early stages of L2 acquisition and during the course of development, as well as examining the nature of L2 ultimate attainment.
