Normal vision (no glasses or contact lenses).
We are wondering whether multisensory integration can happen below level of awareness. In order to investigate it we run audiovisual binocular rivalry experiment. During binocular rivalry two unsimilar images are presented and they don't merge into a unique percept rather they alternate, what subjects have to report. We use mirror stereoscope for the experiment and looking for subjects with normal vision (no glasses or contact lenses).
