Outline of Final Research Achievements

Our emotions are influenced not only by environmental factors and internal factors such as hormonal changes, but also by the emotions of others. In this study, I focused on the synchrony of emotional responses with others and conducted a series of experiments to examine the relationships between emotional synchrony and people's emotion recognition, behavior, and decision making. In a joint task, I found that the higher the synchrony of emotional responses, the stronger the perceived emotion, and published the results in an international journal. In addition, through experiments with orchestras that require complex coordination, I found that the synchrony of emotional responses strengthens as the group performance becomes more sophisticated, and the results will be presented at an international conference. In addition, we have conducted an experiment to examine the effect of synchrony of emotional responses on decision making involving risk.

Academic Significance and Societal Importance of the Research Achievements

本研究では、身体状態や情動が認知や行動、意思決定に影響を与える個人「内」過程に関する従来研究に着想を得て、それが個人「間」過程としても生じる可能性を検討しようとする独創的な試みである。特に、情動反応の同期現象に着目し、個人を超えて集団というマクロなレベルで身体と意思決定のクロスモーダルな関係がもたらすインパクトを検討する点で学術的独自性が高い。一連の研究成果から、集団の共同体験における認知・行動を捉えるためには、個人の情動反応だけでなく、個人間の情動的なつながり（情動反応の同期など）も考慮する必要があることが示された。
