The Test of Variables of Attention (T.O.V.A.) kit contains the hardware and software necessary to install and administer the T.O.V.A. continuous performance test. The T.O.V.A. provides healthcare professionals with objective measurements of attention and inhibitory control. The visual T.O.V.A. aids in the assessment of, and evaluation of treatment for, attention deficits, including attention-deficit/hyperactivity disorder (ADHD). The auditory T.O.V.A. aids in the assessment of attention deficits, including ADHD. T.O.V.A. results should only be interpreted by qualified professionals.
