One type of brain training effective

Participants who completed the speed of processing training experienced improved performance across standard cognitive (attention), behavioral (depressive symptoms, feelings of control), functional (health-related quality of life, functional performance) and real world measures (driving, predicted health care costs).

Edwards pointed to the speed of processing research around driving as a concrete example of how this training generalizes to everyday activities. Studies have shown that speed of processing training resulted in improvement in reaction time, yielding another 22 feet of stopping distance at 55 mph and a 36 percent decrease in dangerous maneuvers. In addition, 40 percent fewer people stopped driving altogether and there was a 48 percent reduction in at-fault crashes, she said.

The future might be a competition between elderly drivers having to take a brain-training course (after an accident in order to keep their licenses) or having to travel in a self-driving car (granted that the latter ever actually becomes safer).
