Sample Dyop Tests

 

Online Dyop Visual Acuity (Visual Clarity) Test

Open the acuity (visual clarity) test with the above link. 

Note the smallest pair of Dyop rings you can detect as spinning.

View the spinning rings at a five-foot distance.

The center row of numbers between the smallest pair of rings you can detect as spinning rings

is the measure of your acuity.

Causes of Dyslexia

 

--------          

Online Dyop Color Screening Test

Open the acuity (visual clarity) test with the above link.  View the spinning rings at a five-foot distance.

The smallest colored Dyop ring (Blue/Black or Green/White) you can detect as spinning indicates your color acuity profile.

Preferentially seeing the Blue/Black rather than the Green/White indicates a probability

of symptoms of dyslexia, migraines or epilepsy.

The center row of numbers between the smallest rings you can detect as spinning is the measure of your color acuity.

Dyop Cognition Impairment Test

A Dyop may also be used to evaluate the cognition impairment associated with conditions such as marijuana intoxication, PTSD, concussion injuries, and other possible cognitive difficulties such as Alzheimer’s.

https://www.dyop.net/documents/Dyop_Cognition_Test.html

Use the link above to open the Dyop Cognition Impairment Test.

Note that THIS is a Timed Test.  Click the word “Start” at the top of the test to begin.

Additional details are at:  https://www.dyop.net/Cognition.htm

(Below is a static image of the initial screen for the Dyop Cognition Impairment Test.)

 

Note that when the test starts, FIVE Dyops will be displayed on the screen but only ONE of them is spinning.

Use a computer mouse or touch screen to click the arrow adjacent to the SINGLE spinning Dyop to indicate its spin direction. That Dyop will stop spinning, but ONE of the other FOUR Dyops will then start spinning.

Click the arrow adjacent to that next spinning Dyop to indicate its spin direction.

 (Below is a static image of the response screen for the Dyop Cognition Test.)

 

When you have found and detected all TEN of the spinning Dyop test response trials, the screen will

display the number of Correct Selections and the elapsed Test Time.

A test completion time of 14 to 16 seconds with 10 correct responses indicates mental alertness.

A test completion time of 21 to 26 seconds with less than 10 correct responses indicates minor mental impairment.

A test completion time of 28 to 32 seconds with less than 8 correct responses indicates increased mental impairment.

A test completion time of 35 to 40 seconds with less than 6 correct responses indicates significant mental impairment.

(Below is a static image of a final response screen for the Dyop Cognition Test.)
