Larger stimulus changes are detected reliably after shorter observation times

Evidence

Change size also influenced the shape of the dependence on change time, such that greater change sizes lead to improved hit rate already for shorter change times (Fig. 1d ). This translates to a combined steepening and leftward shift of the hit rate curves with change size. Significance of this effect was assessed by fitting sigmoidal hit rate curves of individual subjects with a parametric function (see Methods ) in order to extract the change size-dependent time constant (Fig. 1f ). Hit rate time constants Ο„ significantly decreased with respect to change sizes (p < 10‑6 , Friedman test). β€” Dijk, Pim van, Physiology, Psychoacoustics and…, 3329
