This test assesses inattentiveness, impulsivity, sustained attention, and vigilance, and provides information that can be useful to diagnose impairments related to attention.

The test, inspired in the second version of the Conners Continuous Performance Test, requires users to press on the screen as fast as possible when a letter appears, unless the letter is “X”. Letters appear at different time intervals (1, 2, and 3 s) for 15 minutes. After the assessment, the test provides different continuous attention-derived measures, such as omissions, commissions, and reaction time along the evaluation.
