Figure 2. Two User Interfaces for the General Executive Function Brain Training Game.

Left panel is the version where the child follows the moving light and clicks on it when it turns into a jewel that meets the criteria for being a target. There are two moving lights at the game level shown, and at the moment of the screen shot one has just turned to a blue jewel. The clue at the top of the screen shows that the target is blue jewels. The right panel is second user interface for the same cognitive demands and computer code. At the moment of the screen shot, the moving lens (yellow circle) has just revealed a target monkey in the crate, the child has clicked on it and monkey is freed from the crate and is running away. Computer code for the games was created with the text editor Sublime (https://www.sublimetext.com/) and art work created in Photoshop (http://www.photoshop.com/).
