Outline of Final Research Achievements |
We found that when experimenter stroked another rat in front of affiliative rat and during social isolation, these rats emitted novel calls with acoustic characteristics different from those of calls emitted under physical stress. We also examined the effect of oxytocin in formation of an affiliative relationship. The results of pharmacobehavioral experiments suggest that the influence of oxytocin on affiliative behavior may be limited.

Academic Significance and Societal Importance of the Research Achievements |
本研究成果により、ラットの情動を推察しうる新たな音声指標の存在が明らかになった。他者との関係性の神経メカニズムを実験心理学的に調べる上で有用であるだけでなく、コミュニケーション障害や情動の発達を調査するための重要なモデルを提供できることが期待できる。まだ結論を出すに至ってはいないが、本研究によりオキシトシンが他者との親和的な関係性の構築に果たす役割の理解につながる可能性がある。
