Cognitive Endurance

Shrink Definition

Cognitive endurance is the ability to sustain high-quality thinking, attention, and decision-making over extended periods while adapting to mental fatigue and changing demands. It reflects the durability of mental performance, not simply intelligence.

Plain language

Mental performance is measured not only by how well you think, but by how long you can continue thinking well.

Evidence summary

Research across cognitive psychology, human performance, occupational health, and neuroscience demonstrates that sustained cognitive performance depends on sleep, recovery, workload management, and attentional regulation rather than continuous effort alone.
