This study uses fMRI and HMM to show that narrative context modulates brain state dynamics and behavioral responses during story comprehension.

This study develops and tests computational models of criterial learning, finding that delayed feedback impairs learning but long intertrial intervals do not, supporting associative learning mechanisms.

The paper develops a framework linking signal detection theory and encoding models to quantify perceptual separability of neural representations in neuroimaging data.
