Abstract
David Shaker applies Fitts and Posner’s three-stage model (cognition · integration · automation) to surgical skill acquisition — linking cognitive load theory to staged psychomotor practice.

Key findings
- Three stages — Learners intellectualise, refine efficient movement, then automate with minimal cognitive input.
- Cognitive load — Excess extrinsic load in early stages impairs integration.
- Fitts–Posner map — Cognitive · integration · automation — widely used in psychomotor training literature; not a controlled trial of the four-stage coaching ladder.
Limits
Short commentary — cites Fitts and Posner without primary volume depth. Surgical context may not generalise to knowledge work.
Application
When a new skill feels clumsy, you are likely in cognitive stage work — do not demand automation-speed output same week. See Four stages of competence.
