| Abstract: | The aim of the present study was to investigate patterns of similarity in reading related tasks among dyslexic members of the same family. From a sample of 19 well defined dyslexic students in grade 8, three cases were randomly selected for closer examination with a battery of tasks assumed to be causally related to reading. In all selected cases the fathers reported reading disability and in one case the mother was affected as well. The profiles of performance on the various tasks showed a striking similarity within families suggesting similar mechanisms underlying the reading disability. All cases showed remarkable problems in phonological processing, although functional reading skills were almost intact in some cases. Thus, the phonological tasks might be regarded as  marker tasks for identifying genetic dyslexia.Requests for reprints should be sent to Torleiv Høien, Center for Reading Research, Stavanger Teacher College, P.B. 2521, Ullandhaug, N-4004 Stavanger, Norway. |
