Schedule strategic disengagement from demanding cognitive
Schedule strategic disengagement from demanding cognitive work at 50-90 minute intervals to prevent attentional habituation rather than waiting for exhaustion.
Why This Is a Principle
Derived from Directed Attention as Depletable Resource (attention is finite and depletes), Ultradian and Circadian Cognitive Rhythms (ultradian cycles), and The nervous system habituates to repeated, predictable (habituation to sustained stimuli). This is actionable scheduling advice that follows from but is not itself the foundational truth about resource depletion. It's prescriptive: given that attention depletes, here's when to restore it.
