CORE DEFINITION

The approximately 24-hour physiological cycle of an organism (e.g., body temperature, hormone secretion, alertness). It determines when we are most awake, most creative, and best suited for exercise.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Go with the flow. An advanced form of meta-monitoring is to understand your own rhythm (whether you are a lark or an owl) and schedule the most important work during cognitive peak periods, rather than forcing yourself against your natural tendencies.
