Bernard Baars is the cognitive scientist who developed Global Workspace Theory, a major model of consciousness in Cognitive Psychology. He explains awareness as information being broadcast from a limited workspace to other mental systems.
Bernard Baars is the researcher most closely associated with Global Workspace Theory, a major explanation of consciousness in Cognitive Psychology. In this course, his name stands for the idea that conscious awareness is not a separate “thing” in the brain, but a stage where certain information becomes available to many mental systems at once.
Baars’ model starts with a basic problem: your mind does a huge amount of processing without you noticing it. You can read a word, recognize a face, or feel a sound pattern before you can explain how you did it. Global Workspace Theory says these unconscious processes compete for access to a limited workspace, and when one wins, it becomes conscious.
Think of attention as the gatekeeper. It does not create the information, but it helps select what gets admitted into awareness. Once information enters the workspace, it is “broadcast” to systems for memory, language, decision-making, and problem-solving. That is why something becomes conscious when you can talk about it, remember it, compare it, or use it in reasoning.
This makes Baars’ theory useful for explaining why consciousness feels broad even though attention is narrow. You can only actively attend to a small amount at a time, but once something is in consciousness, it can influence many other processes quickly. That is also why distraction matters so much. If competing information keeps winning access to the workspace, your conscious experience changes.
In a Cognitive Psychology class, Baars usually shows up when you study theories of consciousness, selective attention, and the difference between unconscious and conscious processing. A professor might ask you to compare a task you can do automatically with one that requires conscious report, or to explain why anesthesia or coma disrupt awareness under this model.
Bernard Baars matters because his theory gives you a way to explain consciousness without treating it like magic. Instead of saying “we are aware because we are aware,” Global Workspace Theory describes a process you can trace: information is processed, selected, broadcast, and then used by other systems.
That makes Baars especially useful in Cognitive Psychology when you are linking attention, memory, and awareness. If a scenario shows someone noticing a stimulus, holding it in mind, and then using it to make a decision, Baars’ model helps you explain how that information moved through the mind.
It also connects to clinical and everyday examples. States like sleep, anesthesia, coma, and deep distraction can all be discussed by asking whether information is reaching the global workspace. If it is not, the person may still process some input unconsciously, but they will not report it or use it in flexible thinking.
For essays and short answers, Baars gives you a clean framework. You can use him to describe why some mental processing is conscious, why some is not, and how attention acts like a bottleneck rather than a full picture of the mind.

This is Baars’ main theory, so the two terms are almost inseparable. If a prompt asks about Bernard Baars, you usually explain the workspace idea: information becomes conscious when it is broadcast to many systems. The theory is the content, and Baars is the person who is most strongly linked to it.
Working Memory
Working memory often gets discussed next to Baars because both involve holding information in an active, usable state. The difference is that working memory focuses on limited short-term maintenance and manipulation, while Global Workspace Theory explains how information becomes broadly available to the mind. A scenario can involve both at once.
Cognitive Access
Baars’ model is really about access. Information is not just present, it becomes available to report, reasoning, and other mental systems. If you see a question about whether a stimulus influenced behavior without being consciously noticed, cognitive access is the idea to test against Baars’ conscious broadcast model.
Waking Consciousness
Waking consciousness is the everyday state where the global workspace is active and information can be shared across systems. Baars’ theory is often used to explain why waking awareness feels flexible and reportable compared with sleep, coma, or anesthesia. It helps you describe levels of awareness, not just the fact that awareness exists.
A short-answer question may give you a person in a lab, a patient case, or a description of divided attention and ask which theory of consciousness fits. That is where Bernard Baars comes in. You would identify Global Workspace Theory, then explain that a stimulus becomes conscious when attention selects it and the information gets broadcast to other cognitive systems.
In an essay or discussion response, you might use Baars to compare conscious and unconscious processing. For example, you could explain that a person may process a sound or visual cue without awareness, but only the information that reaches the workspace can be reported, remembered clearly, and used in flexible thinking.
If the prompt mentions anesthesia, coma, or a loss of awareness, Baars helps you explain the breakdown of access rather than just the absence of brain activity.
Both theories try to explain consciousness, but they focus on different parts of the puzzle. Baars emphasizes global access and broadcasting across mental systems, while higher-order thought theory says a mental state becomes conscious when you have a thought about that state. If a question asks about attention, access, and widespread availability, Baars is usually the better fit.
Bernard Baars is best known for Global Workspace Theory, a major model of consciousness in Cognitive Psychology.
His theory says conscious information is selected by attention and then broadcast to many mental systems at once.
Unconscious processes can still happen, but they do not enter awareness unless they gain access to the workspace.
Baars helps explain why attention, memory, and reportability are linked in everyday thinking and in lab tasks.
You can use his theory to discuss waking consciousness, distraction, anesthesia, coma, and other changes in awareness.
Bernard Baars is the cognitive scientist most closely tied to Global Workspace Theory, a model of consciousness. In Cognitive Psychology, his work explains awareness as information becoming available to many mental systems after attention selects it.
Baars' theory says the mind has many unconscious processes competing for a limited workspace. When one piece of information wins access, it gets broadcast to systems for memory, language, and decision-making, which is why it becomes conscious.
Baars focuses on access and broadcasting, while higher-order thought theory focuses on having a thought about a mental state. If the question is about what information becomes available to the whole mind, Baars fits better. If it is about awareness of awareness, higher-order thought theory is the closer match.
Use him when a scenario shows attention selecting one stimulus from many or when conscious awareness seems limited. You can explain that the selected information enters the global workspace and can then be reported, remembered, or used in reasoning.
