What analogy is used to describe cognitive energy when concentration suffers due to stress?

Answer

A phone battery running low from too many background apps

When mental clarity declines due to stress impacting higher-level brain functions, an analogy involving resource depletion is used to illustrate the concept. This cognitive energy is compared to a phone battery. When numerous applications—representing worries, distractions, and demands—are running continuously in the background, the primary function, which is focus and attention, suffers dramatically. This vivid comparison emphasizes that the issue isn't a permanent loss of capability, but rather a temporary state where limited mental resources are over-consumed by simultaneous processes.
