This EEG study shows expectations shape brain responses through two phases: initial enhancement of expected visual information, followed by prioritization of unexpected information.

The paper shows that in voice recognition, listeners favor speakers with lower-precision (more variable) voices under ambiguity, challenging the idea that precise expectations dominate perception.

This study shows that both sensory sharpening and prediction errors occur during speech comprehension, operating at different brain levels to support perception and learning.

The paper investigates how auditory and visual speech signals are processed in the brain during speech perception, finding differences in phase-locking patterns between auditory and visual regions during audio-visual and silent lip-reading conditions.

This paper challenges the idea that expectation suppression is due to reduced prediction errors, proposing instead that it results from reduced attention to predictable stimuli.
