The IVA-AE2 Continuous Performance Test (CPT) is a psychological test of visual and auditory attention and impulse control. It is designed to help health professionals in their evaluation of the attention and general cognitive functioning of adults. The use of the IVA-AE2 requires that it be administered in accordance with the specified test guidelines under the supervision of a qualified licensed health care professional. The test by itself is not to be used as a stand-alone instrument in making a diagnosis, but provides data that can be helpful to clinicians as part of their comprehensive evaluation.
