Recall the cognitive control limitations that we presented in chapter 5 in the domains of attention (selectivity, distribution, sustainability, processing speed), working memory (capacity, fidelity), and goal management (multitasking, task switching). As described, high-tech influences stress these limitations in just about every possible way: they challenge our attention abilities via frequent distractions, fragment our working memory and diminish its fidelity through interruptions, and drive us to excessive multitasking and task switching, all of which introduce performance costs.
