Working memory

CereboostTM improves working memory

We assessed three subcategories of working memory : numerical, alphabetic, and visuo-spatial.
For numerical working memory, five digits were flashed on a computer screen sequentially for the participants to memorize, followed by 30 probe digits. The participants decided whether the digit was from the original series and indicated their choice by pressing the corresponding keys, labeled ‘YES' and ‘NO.'
For alphabetical working memory, the test was similar to the numerical working memory, using letters instead of numbers. A series of 5 letters appeared on the screen for the participant to remember. After 4 seconds, the letters disappeared and were followed by 30 probe letters. Participants were instructed to indicate whether the target letter appeared in the original list of five letters by pressing the corresponding ‘YES' or ‘NO' key as quickly as possible.
We noticed that CereboostTM improves working memory speed by nearly 10 % over 6 hours.



Finally, the visuo-spatial working memory was measured thanks to the Corsi Block Tapping Task. A computerized version of the Corsi block task was used in this study. A series of squares appeared on a screen, some of which were illuminated sequentially in quasirandom order. The volunteer then attempted to repeat the pattern by clicking the boxes in the same order with a mouse and cursor. The difficulty increased from 4 blocks upwards.

CereboostTM improves the Corsi block score by more than 15%. By ameliorating this score, CereboostTM increases working memory capacity.


Working memory is constantly solicited, especially at work, and is directly linked to individual performance. These results therefore demonstrate the efficacy of CereboostTM on cognitive performance.
