Here’s a simple comparison table between IIT (Integrated Information Theory) and GWT (Global Workspace Theory) as they relate to consciousness:
|
Feature |
IIT (Integrated Information Theory) |
GWT (Global Workspace Theory) |
|
Core Idea |
Consciousness arises from integrated information (Φ) |
Consciousness is global broadcasting of information |
|
Focus |
Structure and quantity of information in a system |
Cognitive functions and access to information |
|
Originator |
Giulio Tononi |
Bernard Baars |
|
Approach Type |
Mathematical, intrinsic, phenomenological |
Cognitive, functionalist, computational |
|
What Makes a System Conscious? |
High Φ (integrated information); internal cause-effect power |
Access and broadcasting to multiple unconscious processors |
|
Measurement |
Attempts to quantify consciousness (Φ value) |
Describes consciousness functionally, not quantitatively |
|
Biological Substrate |
Emphasizes physical structure of neural networks |
Emphasizes brain areas like prefrontal cortex and thalamus |
|
Criticism |
Difficult to test empirically; complex math |
May not explain subjective experience (qualia) well |
|
Metaphysical Implications |
Panpsychism-friendly; even simple systems may be conscious |
More anthropocentric; consciousness as a human cognitive tool |
|
Use in AI/Neuroscience |
Influences consciousness studies in neuroscience and AI |
Influential in cognitive science and artificial consciousness research |
Would you like a more visual or philosophical comparison as well?
