A research team led by Gakuto Chiba and Yuto Ozaki, PhD students at the Graduate School of Media and Governance, Keio University, along with their advisor, Associate Professor Patrick Savage (Faculty of Environment and Information Studies), and co-researcher, Associate Professor Shinya Fujii (Faculty of Environment and Information Studies), conducted the 1st fully published Registered Report in the field of music studies and published their research paper in the journal Collabra: Psychology on May 22, 2023. The team conducted an online experiment in which 155 Japanese participants were asked to judge the winner of a classical piano and Tsugaru shamisen competition by designing an experiment that controlled for quality (1st-vs. 2nd-placed, 1st-vs. low-ranked) and video viewing conditions (visual vs. audio only) among the performers to study which information dominates in evaluating performance in music. The results showed an interaction between the relative quality of the performers and the relative influence of visual and audio information, and this interaction was found to be general across cultures. On the other hand, the results also showed that visual information dominated the judgment of piano performance among upper ranks, and audio dominated the judgment of Tsugaru shamisen performance between upper and lower ranks, suggesting that cultural factors affect the balance between visual and auditory judgments in musical performance.
