Description

<p>Sound repetition perception is key to understanding our environment. We can detect repeated short bursts of white noise, but longer noise repetitions are harder to notice and cause individual differences. This study explored such individual differences, focusing on spectrotemporal modulation as a cue for repetition perception. We hypothesized that sensitivity to spectrotemporal modulation explains this difference. We measured repetition perception as the d-prime (d’) score and modulation sensitivity as the discrimination threshold. Results revealed a significant correlation between noise repetition detection and modulation sensitivity among participants. Further analysis indicated that musical skill influences modulation sensitivity but not repetition detection directly. This suggests that spectrotemporal modulation is a key cue in the perception of noise repetition.</p>
