How The Scores Are Calculated

For each exercise, the two following variables are mainly measured: Your accuracy and your response time (certain games contain more than two variables). These two measures may be repeated, depending on the number of steps comprised in the game. For example, the game "Objects Where Are You" features three different accuracy rates and response times as there are three different stages: recognizing the objects you have memorized, identifying the squares, and creating the associations (see picture below).

To find out whether you have successfully completed a game, these results are also compared to those of people of the same age range, gender, and educational level.

At the top left corner, your global score is displayed as fully or partially filled stars depending on your performance. It represents a mark out of a hundred. Your cognitive profile will vary based on this mark. If this result corresponds to your peers' median score, your mark will be 50. If your result is higher than the median score then your global score will be between 50 and 100.

Below are the details of your score: There is an average accuracy and response time for each stage of the game.

The right side shows the comparisons of accuracy and response time to your peers'. For each one of these two variables, the following information is available:

• - your score

• - the median is displayed as a green bar: 50% of users achieve a higher score and 50% of users achieve a lower score than the indicated value. You can compare your score to the median value and find out which part of the population you belong to. Careful, don't get too enthusiastic if you have a 70% accuracy score as the median score may be 80% for a simple exercise! This means that half of the people comparable to you achieved a score over 80%, while the other half scored under 80%.

• - an interval of results corresponding to the results of the top 25% of users: In order to help you determine progression objectives, the best 25% are indicated. If you like challenges then you should try to achieve a score within this interval as often as you can.

In order to give you accurate and coherent results, it is necessary to compare them to the results of people you can be compared to in terms of age, gender, and educational level. It probably makes sense to you, for example, that the notion of good or bad results at a cultural game is not the same for a 10 year-old or a 60 year-old.

The diagram below shows a typical chart representing the results of a group of individuals of the same age, same gender, and same educational level for a particular game. You can see the average result of all these individuals in the middle. Most of these people achieve results close to this average value and others achieve even better or worse results. However, the further you move away from this average, the less results there are either way.

• - On the left are the people who struggle (2.5% of the population), not necessarily for pathological reasons but often due to a lack of concentration or anxious reactions when facing an unusual or new exercise - which emphasizes the relevance of the trial stage.

• - On the right are expert users (2.5% of the population).

• - Between the two groups are the remaining 95% of the population: Results within this interval correspond to what can logically be expected.
