How is the brain score calculated?

  • Your training results are used for the calculation of the brain score.
  • Both results from the web and app contribute.
  • Only scores from the last 30 training days are used.
  • This means that if you got a really great score over 30 days ago, your brain score might decrease by no longer including this score.
  • This also means that if you got a bad score over 30 days ago, your brain score might now increase because the result will no longer be included.
  • The brain score of a single exercise takes into account how often you have trained over the last 30 days. The more you have trained with the exercise, the higher your score will be.
  • The brain score inside a category - whether it be numeracy, language, reasoning, memory, perception - is calculated from the mean of all single exercises results
  • The overall brain score is calculated from the arithmetic mean of all five category's brain scores
  • The more you train, the more accurate your brain score will be, since every single exercise works to improve a different aspect of your brain
  • Another NeuroNation member might have a very high brain score, but because they train with only one exercise. Varied training with different exercises will produce better results and your scores will improve over time.
  • The effects of brain training on your brain can only be determined by you.
  • For this reason, comparison to other NeuroNation members is only partly valuable
  • Training with NeuroNation friends allows better and more objective comparisons. You can follow the results of your friends and motivate each other.
  • The highest possible brain score is 181.82. You cannot get a higher score than this, but if you don't train, your score can still decrease.
  • After completing an exercise, you will be displayed a graph with up to 30 bars. If you hover the cursor over one of the bars, you can see the score you achieved and the date which the result was obtained. You will also be shown a bell curve for a percentile comparison to all other members. 
  • Furthermore, you can see if your overall brain score has changed and if you have raised your starting difficulty.
