Auditory motion perception emerges from successive sound localizations integrated over time

V Roggerone, J Vacher, C Tarlao, C Guastavino - Scientific Reports, 2019 - nature.com
Humans rely on auditory information to estimate the path of moving sound sources. But
unlike in vision, the existence of motion-sensitive mechanisms in audition is still open to …

A general framework for inferring Bayesian ideal observer models from psychophysical data
