Dyslexia: One Approach To Optometric Diagnosis.

The objective of this test is to determine if the Dyslexia Determination test does
in fact demonstrate dyslexia as opposed to normal readers. The null hypothesis is that no difference will be shown at the comparable reading levels. To test this hypothesis, the DDT was administered to a group of subjects who were deficient in reading but normal in all other respects. The results were compared to a matched group of normal readers.
