LPI (Lumosity Performance Index) is a standardized performance metric that shows how well you are performing on Lumosity games and lets you compare performance across games and Cognitive Areas. LPI is based on the scores you receive for Lumosity games. It is not influenced by your age or any training preferences you have selected.
We calculate LPI at three different levels: Game LPI, Cognitive Area LPI, and Overall Cognitive LPI.
Game LPI
Game LPI is determined by examining score distributions for each game across a wide range of members. An LPI value is then assigned to each game score. Once these LPI values are established for a particular game, members will receive a Game LPI each time they play that game.
Your Game LPI is updated after every play based on how well you scored in that session compared with your previous performance. We consider all of your recent scores, not just your highest or most recent score.
Cognitive Area LPI
Cognitive Area LPIs (Speed, Memory, Attention, Flexibility, Problem Solving, and Math) are calculated using a weighted average of the Game LPIs for the games you have played within each Cognitive Area.
If you have played enough games in a Cognitive Area, the Game LPIs from your lowest-performing games may be excluded from that Cognitive Area’s LPI calculation.
Overall Cognitive LPI
Your Overall Cognitive LPI is calculated using a weighted average of the Game LPIs across all Cognitive Areas. Since you may not play the same number of games in each Cognitive Area, your Overall Cognitive LPI may not be the same as the average of your individual Cognitive Area LPIs.
If you have played enough games, the Game LPIs from your lowest-performing games may also be excluded from your Overall Cognitive LPI calculation.
Math games are included in your Overall Cognitive LPI calculations.
