Metacognition
noun /ˌmet.ə.kɒɡˈnɪʃ.ən/ — Thinking about one's own thinking; awareness of one's mental processes
Definition
The capacity to observe, understand, and regulate one's own cognitive processes — to think about how one thinks, to monitor whether one understands, to notice when a thought pattern is unhelpful.
Beyond the definition
The skill beneath all other skills. Metacognition is what separates the person who is stuck in their thinking from the one who can step outside it and ask: 'Is this actually working?' It is the observer behind the observer.
Origin & history
From Greek 'meta-' (beyond, about) + 'cognition' (knowing) — from Latin 'cognitio'. Beyond knowing: the awareness that watches the knowing happen. Coined as a term in educational psychology by John Flavell in the 1970s.
