Larger statistical changes in textures are detected sooner and more often
Evidence
These parameters were tested in a single experiment with ~ 1000 trials over two sessions per subject. β¦ Hit rate increased monotonically to an asymptotic level for all change sizes (4 levels, [50, 80, 110, 140] %). β¦ Asymptotic hit rate depended on the change size, with bigger changes in marginal probability leading to greater asymptotic hit rate (Fig. 1d , different colours). β¦ Although asymptotic hit rate was above chance (26.6 %) for all change sizes, the increase with change size was large and significant (from 50 to 95 %, p < 10β7 , Friedman test). β¦ Hit rate time constants Ο significantly decreased with respect to change sizes (p < 10β6 , Friedman test). β Dijk, Pim van, Physiology, Psychoacoustics andβ¦, 3285
