Why the study?
Practice effects are pronounced and likely under-appreciated in cognitive testing.
Correction factors for the Cognition battery can improve interpretation of repeated cognitive assessments by adjusting for practice and stimulus set effects.
May aid adjustment for practice effects in serial cognitive testing; leaves open validation in broader clinical cohorts.
Practice effects are pronounced and probably under-appreciated in cognitive testing. The correction factors established in this study are a unique feature of the Cognition battery that can help avoid masking practice effects, address noise generated by differences in stimulus set difficulty, and facilitate interpretation of results from studies with repeated assessments.
