Comment that's not multitasking (Score 1) 86
As the car/music/walking people show, this isn't really multitasking. True multitasking (vs task switching) would be the agility to engage in two novel cognitive tasks simultaneously. Like watching TV while studying (neither of which is a rote activity), which generally is a task-switching activity.
There's probably a whole subset also of 'Doing activity X while conversing', which does seem to be a form of multitasking most people are wired for (understanding that conversation will dip if the other task's cognitive load peaks, e.g. something weird happens).
