Introducing the Test of Variables of Attention (T.O.V.A.), a computerized test of attention which assists in the screening, diagnosis, and treatment monitoring of attention disorders, like Attention Deficit Hyperactivity Disorder (ADHD).

What is the T.O.V.A.?
The T.O.V.A. is an objective, neurophysiological measure of attention, not a subjective rating of behavior. It is a 21.6 minute long, very simple "computer game" that measures your responses to either visual or auditory stimuli. These measurements are then compared to the measurements of a group of people without attention disorders who took the T.O.V.A.

The T.O.V.A. assists clinicians by: 

• Confirming clinical impression
• Verifying treatment
• Following attention over time
  

Who uses the T.O.V.A.?
The T.O.V.A. is usually used by licensed clinicians, such as psychologists, physicians (including psychiatrists, neurologists, pediatricians and family practitioners), and nurse clinicians to assist them in accurately diagnosing and treating attention disorders.  The screening version of the T.O.V.A. is used in non-clinical settings, such as schools, human resource departments, and rehabilitation programs.

What makes the T.O.V.A. unique?

• T.O.V.A. has a standardized computer game-like format and is easily administered.
• Any personnel can be trained to administer the test.
• Its reports are immediately available and easy-to-read.
• It measures both visual and auditory information processing, yet in separate tests to isolate processing deficits.
• It is extensively normed for both children and adults (ages 4-80 )
• It precisely measures reaction times (±1 ms)
• It is language and cultural free.
• It promotes efficient and effective communication with parents and schools by means of the Home and School Intervention report geneator.
