Abstract: The first reports of phonological, surface and deep dyslexia come
from orthographies containing quasi-regular mappings between orthography and
phonology including English and French. Slovakian is a language with a
relatively transparent orthography and hence a mostly regular script. The aim
of this study was to investigate impaired oral reading in Slovakian. A novel
diagnostic procedure was devised to determine whether disorders of Slovakian
reading resemble characteristics in other languages. Slovakian speaking
aphasics showed symptoms similar to phonological dyslexia and deep dyslexia in
English and French, but there was no evidence of surface dyslexia. The findings
are discussed in terms of the orthographic depth hypothesis.
