For more than 25 years, the King-Devick Test has been a proven indicator of oculomotor visual performance for eye movements during reading, with hundreds of published papers in 19 different countries evaluating the test.  This new version is quick and easier to score on a pass/fail basis with normative data for subjects from 6 years old through adulthood.

The King-Devick reading task is clinically used under head-free condition and the time score is presumed to reflect saccadic eye-movement performance.

"The King-Devick Test is a readily available and useful tool for assessing residual oculomotor functions in a clinical setting and its components can also be used for vision therapy training purposes as well.  The King-Devick Test comprises of one demonstration card and three test cards, which contain several rows of random numbers that become progressively more difficult to follow with either spotting or tracking skills."

"Many studies have been done on the connection between students' eye movements and educational performance. From these studies have emerged several clinical measuring tools for optometric use. One such test, widely used in the United States, Canada, and Australia, is ... the King-Devick test.This test is easy to administer and has been incorporated in many visual screening protocol used by non-professionals. The test is also used in formal investigations into understanding learning-related visual problems."

Ces deux épreuves évaluent les capacités de rapidité oculo-motrice du sujet, dont l'atteinte peut être très marquée chez certains dyslexiques. Dans la première tâche, il s'agit de lire des chiffres disposés en rangées de plus en plus serrées et dont les espacements sur chaque rangée sont irréguliers. Pour effectuer la tâche, le regard doit donc accomplir une alternance de saccades et de fixations ainsi que des retours en arrière aux changements de lignes sans que le sujet ait évidemment le droit de se guider à l'aide du doigt, contrairement au RAN test où une telle aide est permise.

Translation: In the first task, it is to read numbers arranged in rows of increasingly tight and that the spacing on each row are irregular. To perform the task, the eye must perform alternating saccades and fixations as well as flashbacks to change lines while the subject is obviously the right guide to using the finger, unlike the RAN test where such support is permitted.These two tests assess the capacity of visual-motor speed of the subject, whose achievement may be very pronounced in some dyslexics.

Jede der 3 Tabellen besteht aus Zahlen, wobei jede Tabelle wegen der steigenden Leerräume zwischen den Zahlen allmählich schwieriger fließend zu lesen wird. Jede Tabelle wird so schnell und so genau wie möglich gelesen, während sowohl Fehler als auch Geschwindigkeit notiert werden, um eine Bewertung zu ermöglichen. Dieser Test simuliert das Nachverfolgen eines Balls, den man wegen Flutlichts oder eines Hindernisses in der Sichtlinie im Flug verloren hat.

Translation: Each of the three tables consist of numbers, each table will be read because of the increasing white space between the numbers gradually more difficult fluid. Each table is as fast and as accurately as possible to read while both errors and speed are recorded to allow a review. This test simulates the tracking of a ball that has been lost due to flood or an obstacle in the line of sight in flight.

Esta prueba es una mejora de la de Pierce, ya que sus autores pensaron que si la prueba está relacionada con la lectura, sería mejor una prueba donde se requiera que la persona haga fijaciones intermedias aleatorias además de las fijaciones del margen de la página. Esta prueba está formada por los dígitos de los laterales y por 3 números aleatorios separados en el centro de cada fila. Simula la ejecución real oculomotora cuando se lee y contiene una tarjeta de demostración y 3 tarjetas de prueba
