Change detection in stochastic textures depends on statistical prediction rather than spectrotemporal predictability

Evidence

Detecting relevant changes in auditory textures is hence complicated due to the lack of deterministic spectrotemporal predictability, and instead relies on the prediction of stimulus statistics (and their dynamics). The aim of this study is to determine how changes in stimulus statistics are detected under continuous presentation of stimulus. Concretely, we assessed how first-order non-uniform sound statistics are integrated and how listeners disentangle a change in these from the intrinsic stochastic variations of the stimulus. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3288

Categorization

• DEFINE: Contrasts deterministic spectrotemporal predictability with statistical prediction as two distinct detection mechanisms, a useful working distinction.
• corroborated: 2 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 3288
