Perceptual interactions between adjacent time intervals marked by sound bursts

Abstract

Perceptual interactions take place between adjacent time intervals up to ~600 ms even in simple contexts. Let us suppose that two adjacent time intervals, T1 and T2 in this order, are marked by sound bursts. Their durations are perceptually assimilated in a bilateral manner if the difference between them is up to ~50 ms. When T1 ≲ 200 ms and T1 ≲ T2 300 ms. When T2 = 100 or 200 ms and T1 = T2 + 100 or T2 + 200 ms, T1 is perceptually contrasted against T2: T1 is overestimated. When 80 ≤ T1 ≤ 280 ms and T2 ≥ T1 + 300 ms, T2 is contrasted against T1: In this case, T2 is overestimated. Assimilation and contrast are more conspicuous in T2 than in T1. For three adjacent time intervals, T1, T2, and T3, the perception of T3 can be affected by both T1 ...
