How is LPI calculated?

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 how frequently you play, your age, or any training preferences you have selected.

We calculate LPI at 3 different levels: Game LPI, Cognitive Area LPI, and Overall LPI.

Game LPI

Game LPI is determined by examining score distributions for each game across a wide range of users. An LPI value is then assigned to each game score. Once these LPI values are set for a particular game, users will start receiving a Game LPI when they play that game. We readjust your Game LPI each time you play by looking at how well you scored that round, and how that compares to your previous scores for that game.

Cognitive Area LPI

Cognitive Area LPIs (the LPIs for Speed, Memory, Attention, Flexibility, and Problem Solving) are calculated using a weighted average of the Game LPIs for the games you have played in that Cognitive Area.

We will exclude the Game LPIs of your lowest performing games from your Cognitive Area LPI calculation if you have played enough games in that Cognitive Area.

Overall LPI

Overall LPI is calculated using a weighted average of the Game LPIs from all Cognitive Areas. Since you might not play an equal number of games from each Cognitive Area, your Overall LPI may not be the same as the average of your 5 Cognitive Area LPIs.

We will exclude the Game LPIs of your lowest performing games from your Overall Area LPI calculation if you have played enough games on our site.
