Grouping sensory events into chunks is an efficient strategy to integrate information across long sequences such as speech, music, and complex movements. Although chunks can be constructed based on diverse cues (e.g., sensory features, statistical patterns, internal knowledge) recent studies have consistently demonstrated that the chunks constructed by different cues are all tracked by low-frequency […]

In predictive coding (PC), higher-order brain areas generate predictions that are sent to lower-order sensory areas. Top-down predictions are compared with bottom-up sensory data, and mismatches evoke prediction errors. In PC, the prediction errors are encoded in layer 2/3 pyramidal neurons of sensory cortex that feed forward. The PC model has been tested with multiple […]

Continuous target-tracking psychophysics is an innovative experimental paradigm that has emerged as a powerful tool for studying perception, cognition, and visually guided behavior. This review outlines how continuous psychophysics complements traditional forced-choice methods by facilitating rapid data collection, providing insights into the real-time dynamics of perception and action, and enabling studies with special subject populations […]
