Mind Bender is what’s known as a “set shifting” exercise. The exercise is designed to speed up the brain’s ability to engage and attend to a relevant condition, and disengage and ignore an irrelevant condition. By doing so, it helps the brain to be more flexible, nimble, and responsive.
The exercise presents a pair of simple rules. For example, the rules might be “If you see two digits, select the higher number." and "If you see two number words, select the lower number.” It will then display two digits (such as “5” and “7”) or two number words (such as “seventeen” and “two”).
As quickly as possible, choose the correct answer based on the rules given. After an answer is given or the time elapses, another pair of digits or number words will be shown.
Later stages of Mind Bender will have different, more complicated rules to follow.
