Detecting statistical changes in sound improves with listening time and change size

Evidence

The ability of subjects to detect a change in stimulus statistics (Fig. 1a ) improved with the time they were allowed to listen to the initial statistics of the texture (Fig. 1d , progression along ordinate, performance measured as hit rate, p < 10‑6 , Friedman test). Hit rate increased monotonically to an asymptotic level for all change sizes (4 levels, [50, 80, 110, 140] %). Asymptotic hit rate depended on the change size, with bigger changes in marginal probability leading to greater asymptotic hit rate (Fig. 1d , different colours). — Dijk, Pim van, Physiology, Psychoacoustics and…, 3324
