Brain Workshop is an implementation of the Dual N-Back mental exercise. This exercise is a mental activity that has been scientifically shown to improve your working memory (short-term memory) and fluid intelligence. The game involves remembering a sequence of spoken letters and a sequence of positions of a square at the same time. Brain Workshop includes additional challenging game modes beyond Dual N-Back.
ChangeBlindness is a small game that demonstrates the change blindness phenomenon. The effect shows that our brains have a low-level (i.e. subconscious) change detection capability that can be disabled pretty easily (for instance, with a flicker of around 100ms). The game illustrates this using an increasing number of icons, one of which will change during a flicker. The goal of the game is to find the changing icon as quickly as possible.
