Dynamic process of auditory temporal context modulating visual temporal processing

Specifically, we examined how visual temporal context modulates auditory duration judgments and used EEG to reveal the neural basis of supramodal temporal representation.ParticipantsTwenty university students participated in the formal experiment (11 females), with a mean age of 20.70 ± 1.63 years.

All participants were right-handed, had normal or corrected-to-normal vision, normal hearing, and no history of brain injury or neurological disorders. The study was approved by the ethics committee, and all participants provided informed consent.Experimental TaskA cross-modal (visual-to-auditory) duration discrimination task was employed. Participants first viewed a 1.1-second visual standard duration (white circle), then heard an auditory comparison duration (440 Hz pure tone) of varying lengths, and judged which was longer.
