I have access to the article [1] through my university, here is the description of the procedure: The study took place in the students' classroom, once a week over an 8 week period. [...] On the first week, demographic questionnaires and the computerized DCCS and Flanker tasks were administered. The Alien Game was then introduced to the students [..] They then played through the first, tutorial level to learn the basics of the game. For the next 6 weeks, students were asked to sign in and play for 20 min per week. Each week, the next two levels of the game were unlocked. [...] On the final week, the DCCS and Flanker tasks were administered again, and students were given a posttest questionnaire asking about their experiences with the game. So if I understand correctly, that was: - 1st week: just the questionnaire and test, plus demo - weeks 2 to 7: play the game 20 minutes - week 8: test again So it seems the performance improvement was measured one week after the last game session.
