Shared Mental Model
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
A construct from team cognition research describing the degree to which members hold compatible mental representations of the task, the equipment, and each other's roles. The core proposition is that when members can anticipate each other's actions and information needs, coordination becomes implicit and errors decrease, which matters most under time pressure. The key qualification is that the model must be updated as the situation changes, since a shared but outdated model produces confident, coordinated errors.
SCAFFOLDING EFFECT
Reduce cognitive load
- Explicit alignment: state the key assumptions about task, roles, and process out loud. - Reinforcement loop: use training and debriefs to keep the representations aligned. - Model refresh: update the shared picture whenever the task or team changes.
Anchor fast decisions
Each member acts on their own prediction of what others will do, so the quality of coordination depends on whether those predictions agree. When the representations match, members anticipate needs and hand off work without explicit requests, which saves time exactly when time is scarce. Divergence produces duplicated effort and gaps, and neither party notices until the outputs conflict.
