The first role of trained infotention is to recognize whether or not multitasking, single-minded focus, or alert but diffused attention is the most appropriate mind-tool for the task at hand. However, for those many situations in which multitasking is either necessary or preferable or both, the most important question is whether -- and to what degree -- multitasking more effectively is a learnable skill. -- Howard
"Results showed that participants did much better at multitasking after training. Interestingly the benefits transferred to the untrained dual task. Brain training can thus be used to get better at multitasking!"
