Definition
Plain language
A small shared space in a mind where a few thoughts get broadcast to the rest of the system, while most processing happens quietly on the side.
As stated in the literature
A theory from neuroscience holding that conscious access works by posting a limited set of representations to a broadcast channel available to many subsystems; the paper argues language models grow a functional analog that carries deliberate reasoning.
Also called: global workspace theory, workspace theory, workspace
Why it matters: It offers a way to explain how a system with many separate parts can still act on one shared idea at a time, rather than pulling in every direction at once.
For example, while reading a book your mind quietly handles breathing, posture, and background noise, but the one sentence you're focused on gets shared across your attention, memory, and speech.
