The Effect Of Digit Automaticity On The King-Devick Saccadic Test.

Accurate, conjugate eye movements, saccades are critical in the reading process, but to clinically separate these movements from other complex factors involved in reading is
extremely difficult. The King-Devick Saccadic Test (K-D Test), an optometric oculo-motility test, is widely utilized to detect poor saccadic movements of children or adults with possible
reading disorders. The K-D Test, however, must be examined closely for possible contaminating elements that may be involved and taken for granted by the examiner when reviewing results of this test. The present study investigates one possible contaminating
factor, the automaticity of digit knowledge, and how this may affect the outcome of the K-D Test.
