Advances in neurobiology and computer science make possible interventions designed to strengthen basic processes behind emotional control. We present one such computer-based intervention, RAGE Control (Regulate And Gain Emotional Control). This extends the usual paradigm of biofeedback by requiring relaxation in the midst of engaging executive processes in a quick reaction task. RAGE Control teaches children to simultaneously focus, react, inhibit impulses, and keep their heart rate down in the context of a traditional space battle game. The program is grounded in the theory of Cognitive Behavioral Therapy and is currently in clinical use by psychotherapists at Children's Hospital in Boston. It aims to reduce the need for psychotropic medication to help children gain emotional control. Clinical trials to test the promise of this technology are warranted.
