On Defining "Dyslexia."
Tonnessen, Finn Egil
Scandinavian Journal of Educational Research, v39 n2 p139-56 Jun 1995
The most influential definitions of "dyslexia" are subjected to a critical analysis. Definitions are grouped according to the principles of symptoms, causality, and prognosis. The major conclusion is that proposed definitions of dyslexia should be treated as hypotheses that should primarily describe symptoms. (SLD)
