- Accuracy: With special tools, the T.O.V.A. can control measurements and timing with ±1 ms accuracy:
- Using an external measuring device (the T.O.V.A. microswitch), more precise than a mouse or keyboard can be
- Eliminating operating system delays through the use of the Precision Testing Environment (PTE), or with External Audio/Video (EAV) testing, which is independent of your operating system
- Compensating for the quirks of display timing with our monitor calibration
- Duration: Research shows many individuals with attention problems can process information normally for 10-15 minutes and then experience difficulty. The T.O.V.A. is the only CPT that measures attention variables for a full 21.6 minutes for subjects five-and-a-half (5.5) years old and above. The T.O.V.A. keeps the task long and boring.
- Stimuli: Unlike other commercially available CPTs that use numbers or letters, the T.O.V.A. uses geometric shapes, so that language and learning disabilities do not interfere.
- Simple task: Unlike most CPTs that use complex tasks that are influenced by learning or working memory, the T.O.V.A. uses a simple go/no-go task to obtain an objective measure of sustained attention.
