| Outline of Final Research Achievements |
To develop a new test battery for non-invasively measuring the emotions of mice, we collected time-series data on ultrasonic vocalizations, body temperature, and facial expressions in social and aversive situations. We also collected behavioral data concurrently and examined the time series analysis (using repeated measures correlation and Granger causality) among these measures. As a result, significant correlations were detected among various indices, but it was too complex to comprehend. Therefore, it is necessary to explore the statistical methodologies for aggregating the time-series data.

| Academic Significance and Societal Importance of the Research Achievements |
社会的に大きな変化がみられる動物倫理の観点からすれば、実験動物にとってより負荷の少ない情動測定方法の開発は喫緊の課題だと考えられる。ペット等の小動物の情動測定については社会的なニーズが高まりつつあり、動物の情動測定技術の応用面を考える上でも、その非侵襲的な測定法は社会的に望まれる技術である。測定技術の進歩から膨大な時系列データを収集することは心理学でも可能となってきたが、そうしたデータの集約方法について検討を続けることは今後も必要であり汎用性の高い学術的価値がある。
