Playing a science-based mobile gaming app for 25 minutes can reduce anxiety in stressed individuals, according to research. The study suggests that 'gamifying' a scientifically-supported intervention could offer measurable mental health and behavioral benefits for people with relatively high levels of anxiety. The game is based on an emerging cognitive treatment for anxiety called attention-bias modification training. The treatment involves training patients to ignore a threatening stimulus (such as an angry face) and to focus instead on a non-threatening stimulus (such as a neutral or happy face). This type of training has been shown to reduce anxiety and stress among people suffering from high anxiety.
