Overview

Human EEG analysis shows sensory encoding of auditory evidence and prior expectations predict decisions, suggesting neural dynamics play a critical role.

Key Points

  • Sensory encoding fidelity uniquely predicts single-trial choices and confidence, highlighting its relevance in decision-making.
  • Probabilistic cues influenced alpha-oscillatory patterns and shifted response bias, but did not alter temporal integration dynamics.
  • Model-based EEG study augmented evidence accumulation tasks to measure the effect of prior expectations.
  • Findings emphasize the interaction between neural noise and expectations in shaping perceptual decisions under uncertainty.
