Memorado has initiated the Global Cognition Initiative (GCI) with the aim to help advance the understanding of human cognitive abilities


Advancing the understanding of human cognitive abilities

  • The Global Cognition Initiative (GCI)
  • is an open-source, collaborative research initiative. It connects Memorado's in-house scientists with scientists, researchers, practitioners and teachers around the world who are interested in the research on cognition.

  • PD Dr. Strobach and Prof. Dr. Huestegge
  • from University of Hagen / Humboldt-University of Berlin and University of Wuerzburg are
    two of the scientists currently working with Memorado. We are research focused and looking
    for you to join us in building a strong research community.

Your advantages as a researcher:

  • Free access to the Memorado Training Program
  • Free use of in depth analytics tools
  • Access to anonymized data and statistics on
    • Games and Workout performance
      • In various cognitive tasks
      • At various times of the day
      • At stratified engagement levels
      • For different age groups
      • By gender
    • Dati longitudinali sul progresso degli utenti

Researchers from all over the world

have joined GCI to conduct scientific studies on cognition based in cooperation with Memorado. If you are interested too, feel free to get in touch.

Immense improvement in the field of fluid intelligence

In this paper, Dr. Susanne Jaeggi and her colleagues present evidence that training your working memory improves fluid intelligence. This means that the improvements do not only occur in the specific task that is trained, but also transfer to other tasks. Before this study, it was commonly believed that intelligence could not be trained but was genetically given. Fluid intelligence is important for various cognitive tasks as well as for learning.

Progress in all fields of cognitive capability

This study conducted by the Max-Planck-Institute in cooperation with Humboldt-University in Berlin examined 101 young adults and 103 seniors as they took part in a daily brain training program for 100 days. The researchers discovered not only improvements in the individual exercises, the participants also showed progress in their general cognitive capability. This means the participants demonstrated improvements in tasks that were not related to the exercises they trained in the program.

Our studies

Current study: Cognitive behavior by time of day

Our Science Team has analyzed our users' training habits in order to determine when they prefer training during the day and at what time they perform best. This study also examines whether different types of tasks show different performance patterns. If you would like to get involved in the Memorado reseach program, or simply want to find out more, please contact: [email protected]


  • Based on personal preferences and schedules, Memorado users work out at different times throughout the day.
  • Taking into account human circadian rhythms, cognitive performance has proven to reach its highest levels at a high core body temperature (CBT) (1)
  • This analysis will also examine whether different types of tasks show different patterns throughout the day, as has been shown in previous studies (2).
  • This analysis aims at finding out when users are most inclined to play and compares these results to the users’ performance.
  • Relating the time of day to a user‘s performance is a further step in personalizing the training program
  • It will be examined if different types of tasks show different patterns of performance and preference throughout the day.
  • This analysis can also offer valuable information for employers who gain knowledge on their employees’ most productive time of day.


  • Participants chosen for this analysis are aged 18 and older.
  • Only participants from Germany, Austria and Switzerland were chosen due to time zone differences in other countries.
  • A variety of 20 exercises were chosen to account for all areas of brain training.


When are the games played the most?

  • Concentration and logic games peak in the early morning (between 8 and 10am). The have a second, slightly smaller peak in the afternoon (between 2 and 5 pm).
  • The popularity of games training speed, memory and reaction increases through the day, peaking in the afternoon (between 3 and 7 pm).






Maximum difference between 8 am and 8 pm is 2.3% (concentration) Two notable peaks are around 9 am and 4 pm.

When do users perform best?

  • Users playing speed and reaction games achieve higher scores in the morning. Scores decrease during the day and rise again in the late evening.
  • Memory games receive the highest scores in the late evening
  • Users training concentration and logic achieve mostly stable scores throughout the day, have a low point in the evening, but scores peak in the late evening.







There are a few aspects that can be examined in a further study. Do the popularity or game scores differ between the various age groups or between genders? Further studies should also examine at what time of day a user shows the most improvement and whether these improvements also occur with untrained tasks.
