Interactions between auditory statistics processing and visual experience emerge only in late development

Summary: The auditory system relies on local and global representations to discriminate sounds. This study investigated whether vision influences the development and functioning of these fundamental sound computations. We employed a computational approach to control statistical properties embedded i...
