When observing others’ behaviors, we continuously integrate their movements with the corresponding sounds to enhance perception and develop adaptive responses. However, how human brain integrates these complex audiovisual cues based on natural temporal correspondence remains unknown. Using electroencephalogram, demonstrated that rhythmic cortical activity tracked hierarchical structures in audiovisually congruent walking footstep sounds. Remarkably, tracking effects at different time scales exhibit distinct modes of multisensory integration: an additive mode a basic-level, narrower integration window (step-cycle) super-additive enhancement higher-order, broader (gait-cycle). Moreover, only higher-order is specialized for motion signals correlates individuals’ autistic traits, suggesting its functional relevance biological social cognition. These findings unveil multifaceted roles entrained motion, shedding light neural coding orchestrates processing complex, stimuli contexts.

When observing others’ behaviors, we continuously integrate their movements with the corresponding sounds to enhance perception and develop adaptive responses. However, how human brain integrates these complex audiovisual cues based on natural temporal correspondence remains unclear. Using electroencephalogram (EEG), demonstrated that rhythmic cortical activity tracked hierarchical structures in audiovisually congruent walking footstep sounds. Remarkably, tracking effects exhibit distinct multisensory integration modes at two scales: an additive mode a lower-order, narrower window (step-cycle) super-additive enhancement higher-order, broader (gait-cycle). Furthermore, while neural responses lower-order timescale reflect domain-general process, higher-order is exclusively engaged of biological motion cues. In addition, only this domain-specific effect correlates individuals’ autistic traits, highlighting its potential as marker for autism spectrum disorder. These findings unveil multifaceted mechanism whereby supports motion, shedding light coding orchestrates processing complex, stimuli across multiple timescales.

Seeing the face of a speaker facilitates speech recognition in challenging listening environments. Prior work has shown that visual contains timing information to aid auditory processing, yet how these signals are integrated within system during audiovisual perception remains poorly understood. Observation preparatory mouth movements may initiate phase reset intrinsic oscillations, potentially sensitizing for receptive while observation post onset facilitate entrainment envelope. Yet, little been done test whether enhances encoding onset, envelope tracking, or both, and through independent overlapping mechanisms. To investigate this, we examined ways which alters theta band power using human intracranial electroencephalography (iEEG) recordings large group patients with epilepsy (n = 21). elicited (increased inter-trial coherence; ITPC) throughout superior temporal gyrus (STG), is thought enhance encoding. Following modulated ITPC only at anterior STG electrodes was posterior electrodes. Pre- post-speech were spatially temporally dissociated, consistent hypothesis tracking mechanisms partially distinct. Crucially, congruent incongruent speech, designed here have identical about time, but different evolution, produced small difference oscillations STG, highlighting more restricted role ongoing entrainment. These results support improves precision two separate mechanisms, encoded entire STG.
