Brief summary
The purpose of this study is to evaluate test-retest reliability of each subtest (correlation coefficients for Time 1 and 2) in the Brain Performance Test (BPT, Lumos Labs, Inc.).
Detailed description
This is an open-label, randomized online study in which participants will be invited to take versions of the Brain Performance Test (BPT) on two consecutive days. In parallel, all current Lumosity subscribers are invited to take the BPT at the beginning of their premium Lumosity experience and again every 10 weeks.
