Syllabus: How Can We Study Conscious Experience?
Follow how predictions about content, duration, and connectivity become measurable criteria across methods.
Why you’re reading it. Evaluate a direct theory comparison alongside the earlier concerns about report, prerequisites, and consequences.
A question to consider. Choose one challenged prediction: what observation would help distinguish a failure of the theory from a failure of an auxiliary assumption about task or measurement?
Why this reading
Researchers with competing commitments agree in advance on predictions, comparisons, and interpretations. The Cogitate collaboration makes that process inspectable across three neural measurement methods. Its contribution is a demanding test of specified claims and an example of how disagreement can organize research.
Before you read
IIT abbreviates integrated information theory; GNWT abbreviates global neuronal workspace theory. Decoding uses neural measurements to classify stimulus features. Ignition denotes a proposed rapid activation associated with information becoming globally available. fMRI, magnetoencephalography, and intracranial EEG offer different spatial and temporal information. The task uses clearly visible stimuli rather than contrasting conscious and unconscious trials.
Read for
- Trace the three predictions concerning content, duration, and connectivity from the preregistered criteria to the results. Separate a shared prediction from one that distinguishes the accounts.
- Compare findings across modalities and distinguish data used to optimize analyses from independent testing data. That split applies to fMRI and MEG, not identically to intracranial EEG.
Consider afterwards
- If a predicted offset response is absent, which auxiliary assumptions determine what this means for a theory?
- Why is decoding stimulus information insufficient to establish how the brain uses it?
Editorial context
The findings challenge specified predictions while supporting others; they do not settle every version of either theory. A later GNWT response disputes the centrality of offset ignition and emphasizes the lack of a conscious–unconscious contrast. Compare that objection with the consortium's advance agreement and testing rationale. Residual task engagement, sampling, and the limited range of experiences remain relevant.
