Which statement best captures distributed cognitive systems?

• A. They can span multiple individuals or agents
• B. They are restricted to a single individual's mind
• C. They rely only on hardware sensors
• D. They require disembodiment

Answer: (A)

Distributed cognitive systems describe thinking that is spread across people, tools, and the environment, not confined to a single brain. This view holds that cognition can be shared across multiple individuals or agents, with information, memory, and problem-solving distributed through interactions with artifacts, interfaces, and each other. The statement that best captures this is that they can span multiple individuals or agents, because it directly reflects how thinking can be distributed across social and material resources in real-world tasks. For example, a team using a common dashboard, checklists, and collaboration tools demonstrates how knowledge and reasoning flow through people and artifacts together. Limiting cognition to one mind misses this collaborative and tool-enabled nature. Relying only on hardware sensors misstates the full picture, since distributed cognition includes social and environmental components, not just sensor data. And requiring disembodiment isn’t necessary—the approach can be embodied in both people and machines as they interact with the world.
