Reliability and Validity of Online Cognitive Assessments

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the concurrent validity (correlation coefficient of scores at 1 time point) between the Brain Performance Test (BPT, Lumos Labs, Inc.) and a validated third party computerized assessment.

Detailed Description
-----------------
Each subject will complete two sessions, each approximately 1 hour in total duration, approximately 2 weeks apart for a total duration of participation of 2 hours over 2 weeks
