Synchronized sounds selectively boost non‑dominant‑eye perception ― Study by Dr. Hikari Takebayashi and Prof. Yuji Wada published in Cognitive Processing

A new article by Dr. Hikari Takebayashi (Senior Researcher, Ritsumeikan‑Global Innovation Research Organization) and Professor Yuji Wada (RARA Fellow) demonstrates that precisely timed tones enhance spatial localization when targets are presented to the non‑dominant eye during binocular viewing. No comparable benefit emerged for orientation discrimination, indicating that temporal audio cues primarily support “where” information and may act before binocular fusion, with potential applications in low‑vision training.
