Subtyping of reading disorders: Implications for remediation.

Present research methods do not seem to be leading us toward general agreement regarding reading disability subtypes. Even if there were agreement, conventional group research designs are not adequate for determining the optimal remedial procedure for each subtype. It is recommended that careful thought be given to the formulation of more appropriate theoretical frameworks and behavioral measures, and that single-subject research designs which yield information about subtypes and remediation effects be designed through collaboration of researchers and practitioners.
