Listeners detect statistical changes in ongoing sound based on time available for evidence integration

Evidence

This change detection task allows us to explicitly address the integration of statistical information under continuous conditions, which models more closely the real-world challenge of detecting changes in complex ongoing auditory scenes. In this context, we studied the dependence of detection on the time and size of the change. We found evidence for integration of statistical information to predict a change in stimulus statistics, both based on hit rate as well as on reaction times. The main predictors appear to be the time available for integration of evidence. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3286

Categorization

• QUESTION: Presents findings as summary (‘main predictors appear to be the time available for integration’) without detailed numbers; worth chasing the full study for effect sizes and time constants of statistical integration.
• SHARE: For anyone working on auditory scene analysis or statistical learning in perception.
• corroborated: 2 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 3286
