Abstract A growing body of research links individual differences in the frequency alpha-band oscillations to temporal aspects perception. However, whether human alpha rhythm is a correlate time perception itself has remained controversial. This multi-day study combined EEG with multiple duration estimation and discrimination tasks order evaluate (IAF) associated sensitivity or bias judging visual durations across range peri-second (spanning 1200 100ms). In task, participants (n = 55) reported single stimulus between 300-1200ms. which two stimuli was longer: standard (100, 600, 1200ms) comparison (50-150% standard). Stimuli also varied their luminance static dynamic (varying randomly over time). We found that IAF significantly related variance estimates, measure precision (or sensitivity), but not average bias. Further supporting this relationship, psychometric function slopes obtained from independent were correlated IAF, particularly for conditions. These effects largely consistent tested held when controlling participant age. Taken together, these results suggest plays role shaping we did observe spontaneous fluctuations single-trial frequency, suggesting effect primarily observable at cross-subject level. Significance Statement Brain waves 8-13 Hz range, known as waves, have long been hypothesized modulate our time, yet evidence remains unclear. investigates relationship an individual’s using wide address gaps literature. demonstrate estimates discrimination, unchanging stimuli. findings provide novel shapes perception, emphasizing its neural marker sensitivity.
