Test of Variables of Attention

The Test Of Variables of Attention (T.O.V.A.) is a neuropsychological assessment that measures a person's attention while screening for attention deficit hyperactivity disorder. Generally, the test is 21.6 minutes long, and is presented as a simple, yet boring, computer game. The test is used to measure a number of variables involving the test takers response to either a visual or auditory stimulus. These measurements are then compared to the measurements of a group of people without attention disorders who took the T.O.V.A. This test should be used along with a battery of neuropsychological tests, such as a detailed history, subjective questionnaires, interviews, and symptom checklists before a diagnosis should be concluded.
