How to Rebuild an Attention Span - Douglas Foster - The Atlantic: " . . . For users, the game relies on familiar conventions. When the screen lights up, the road reveals itself. On my first run at NeuroRacer, done sitting behind a computer in a darkened lab, I thought: Piece of cake, what idiot couldn’t master this? Controlling the direction by a modem operated on the right, I managed to hold my sporty auto avatar in its lane for several seconds. Then, unfortunately, the road kept slipping away from me, winding around curves, and unexpectedly rising and falling in elevation. The multitasking version of the game required me to drive and, simultaneously, respond accurately through a button on the left to signs that popped up at random on the screen. Designers of NeuroRacer used an “adaptive staircase algorithm” to ratchet up the level of difficulty, meaning that each time a participant improved enough to respond accurately at least 80 percent of the time the challenge increases incrementally. This component of the research is the study’s “special sauce,” Gazzaley told me. The adaptation allows participants of different ages and abilities to start at an equivalent level of comfort and provides a basis for valid comparison across age groups. . . ."
