| Outline of Final Research Achievements |
The current project aimed to explore psychological foundations to form collective behaviors. We trained budgerigars in a skinner box using an operant conditioning technique. One pair composing of two birds were trained to make response chain which were produced alternately by them in a task. As a result, one bird in a pair pecked slightly before the stimulus onset, suggesting that the birds must receive some signals from their partner's cage. And a male bird pecked more rapidly when paired with a bird he preferred more, suggesting that a male bird adjusted his timing depending on his preference. The partner-dependent behaviors shown by our birds might be a elements of collective turn-taking.
We submitted a paper composing of these results to an international journal.

| Academic Significance and Societal Importance of the Research Achievements |
協調運動はヒト文化にみられ、社会的関係を促進することから、それらの関連性について多くの議論が交わされてきた。この研究では生物学的基盤に目を向けるべく、セキセインコを対象に協調運動と社会的な要因がそれに及ぼす影響を検討した。トリは相手個体を手がかりに運動を制御すること、選好によってつつきタイミングを調整することが示された。
この研究は実験下で生得的な運動レパートリーに含まれない協調運動を生み出した。このような後天的に獲得される協調運動の萌芽を示す実験系の構築によって、実験下での協調運動を検討する独自性のある手法と示唆が提起された。
