One of the best attention tests on the market. Not only very sensitive to attention disorders, but it can also detect underperformance or reduced effort!

The Test of Sustained Selective Attention (TOSSA) arose from the need for a short and sensitive attention test. It is an 8-minute auditory continuous performance computer test with a variable ISI. This dynamic adds extra power to his sensitivity.

The TOSSA has been reviewed as fair to good by the COTAN (Dutch committee on tests) and is one of the best standardized neuropsychological tests available at the moment.

Positive points of the TOSSA

  1. most sensitive attention test at the moment and well on its way to becoming a *gold standard* for attention disorders!
  2. underperformance or reduced effort is also detected!
  3. short but powerful enough to detect attention deficits very reliably without overdiagnosis (also in ADHD)
  4. easy to install and administer
  5. very stable as a test, on a stand-alone computer
  6. can be used for visually impaired and blind people
  7. interpretation since version 3.0 has been greatly simplified because multiple profiles are calculated (e.g. mental slowness, fatigue, conditional impulsivity)

PLEASE NOTE:

It is advisable to first test the TOSSA via the DEMO. The DEMO is fully functional but only for a few days. That gives you the opportunity to test the TOSSA. If this goes well, the TOSSA demo version can easily be transferred to a 1-year license test after payment has been received. The DEMO is always free of use.

In addition, you always have a 14-day cooling-off period after purchase and payment. If you are not satisfied with the TOSSA for any reason, you may submit a cancellation request via the Contact form within 14 days after payment. You will then be reimbursed for the full amount we have received within 10 days.
