The purpose of this study is to evaluate the concurrent validity between the Brain Performance Test (BPT) subtests and corresponding conventional in-person neuropsychological assessments (NP).
This will be a multi-site, randomized, counterbalanced, two-period, two-sequence, validation study of the online, unsupervised Brain Performance Test (BPT). Over the course of 14 days, participants will complete two in-clinic visits during which they will complete both the BPT and in-person neuropsychological assessments (NP).
