Hypothesis
Human cognition consists of cascading cycles of recurring brain events.
Conclusion
The study proposes a timing model for cognitive cycles, suggesting that each cycle takes approximately 260–390 ms.
Supporting Evidence
- An initial phase of perception occurs 80–100 ms from stimulus onset.
- A conscious episode follows 200–280 ms after stimulus onset.
- Action selection occurs 60–110 ms from the start of the conscious phase.
- The entire cognitive cycle takes 260–390 ms.
- The LIDA model fits a large body of cognitive and neuroscientific evidence.
Takeaway
Our brains work in cycles, like a clock, where we sense things, think about them, and then decide what to do, all in a fraction of a second.
Methodology
The study used empirical and simulation data to propose a timing model for cognitive cycles.
Limitations
The timing estimates are based on simple tasks and may not apply to more complex cognitive processes.
