This article presents an experiment in which participant’sworking memory, tasks-switching and focusing skills aretrained in a game called Wollie on a smartphone. Before andafter the training period they performed three task (a recall,Stroop and task-switching). The goal of this research was tosee how the participants, from the test group, learn withinthe game and how this affects the three tasks. Only in theStroop results a clear difference between the two groups wasfound. However, we found that participants who had the mosttrouble in playing Wollie, improved the most on Stroop andtask-switching, indicating that these participants still lackedthe relevant skills for all these tasks.
