Distributed Cognition Complete Cheatsheet

Introduction

Distributed Cognition is a theoretical framework that extends cognitive processes beyond individual minds to include interactions between people, tools, and representations in the environment. Developed by Edwin Hutchins at UC San Diego, this approach views cognition as distributed across individuals, tools, and representations rather than confined within individual heads. It’s essential for understanding how complex cognitive work happens in teams, organizations, and human-technology systems.

This framework is crucial for designing effective human-computer interfaces, improving team collaboration, optimizing organizational learning, and creating intelligent systems that augment human capabilities rather than replace them.

Core Concepts & Theoretical Foundation

What is Distributed Cognition?

• Beyond Individual Minds: Cognitive processes span multiple people, tools, and environmental structures
• Systemic View: Focus on cognitive systems rather than individual cognitive agents
• Embodied and Situated: Cognition is embedded in physical and social contexts
• Tool-Mediated: External representations and artifacts play active cognitive roles
• Collaborative Intelligence: Group cognition emerges from coordination and communication

Key Principles
