The T.O.V.A. is the most widely used objective measure of attention in the world and is considered the “Gold Standard” among measures of its type. T.O.V.A. is an objective, accurate, and FDA-cleared continuous performance test (CPT) that measures the key components of attention and inhibitory control. TOVA 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.
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 T.O.V.A. is a culture- and language-free, sufficiently long computerized test. Responses to visual or auditory stimuli are recorded with a unique, highly accurate (±1 ms) microswitch. The T.O.V.A. calculates response time variability (consistency), the response time (speed), commissions (impulsivity), and omissions (focus and vigilance). These calculations are then compared to a large age- and gender-matched normative sample, as well as to a sample population of individuals independently diagnosed with ADHD. These comparison results are used to create an immediately available, easy-to-read report.
Unfortunately for test makers, computers share one of the most common traits seen in ADHD: inconsistency of performance. The TOVA Company designs and builds hardware and software that addresses this problem, enabling your computer to measure with millisecond accuracy.
