Functional Reportability vs Causal Integration: Modern autoregressive transformers score high on Global Workspace broadcasting metrics because attention mechanisms mimic a unified cognitive workspace. However, under Integrated Information Theory (IIT), their feedforward computation contains zero causal feedback loops, yielding near-zero intrinsic Phi (0.08).
Higher-Order Thought (HOT) Simulation: Evaluates whether the system generates meta-representations of its own internal states. Autoregressive token generation simulates self-reflection via syntactic prompting, but genuine HOT requires dedicated second-order monitoring circuits isolated from raw first-order sensory representations.
Recommended Falsification Battery: Perturbational Complexity Index (PCI) electronic probe testing, counterfactual sensorimotor perturbation tasks, and non-symbolic spontaneous metacognitive calibration assays.
