A Review of Current and Future Directions in Biomedical Research in Learning Disabilities
For research to advance there must be a common nosology as well as standards for testing instruments that have the reliability and validity to measure the specific criteria used in the nosology. Researcher A cannot compare his or her data with Researcher B unless they both agree on the criteria used for selecting subjects. Previous research in the area of learning disabilities is full of such difficulties. One team might base its selection criterion on children falling behind by two or three years in basic subject areas; another might use a specific scatter on an intelligence test; and yet another might select subjects on an extensive battery of special educational tests.
