Outline of Final Research Achievements

In this project, we investigated human auditory across-channel processing which occurs in different frequency channels and in different ears, and its commonality in time, space, and speech perception.
We found significant correlations among some of the psychoacoustical indices of across-channel processing for those three domains of perception. This finding was corroborated by neuroscientific measures of auditory brainstem and cortex. We also obtained data indicating that across-channel processing was likely to operate in vision.
