Introduction / ラボ概要

We are tackling the mysteries of the evolution of intelligence through both cognitive research in captivity and fieldwork in natural environments with a variety of animal species. In particular, we are interested in social intelligence and our main research keywords are empathy, understanding others, cooperation, culture, and group-mindedness. Our research subjects and methods are diverse, dealing with a wide range of topics from hormones to socioecology with methodology of cognitive and behavioral experiments, drone observation, social network analyses etc. We are also working to realize a better harmoneous society between humans and non-human animals, regardless of whether they are wild, domestic, or companion animals.

さまざまな動物種を対象に、飼育下の認知研究と自然環境下のフィールドワークの両方を通して知性の進化の謎に取り組んでいます。とくに社会の中で発揮される知性である社会的知性に関心をもっており、主なキーワードは、共感・他者理解・協カ・文化・集団社会です。オキシトシンをはじめとするホルモンから社会・生態まで幅広く扱い、認知・行動実験からドローンを用いた観察や社会ネットワーク分析など、研究対象・研究手法ともに多岐にわたります。野生動物・家畜・伴侶動物を問わず、動物とヒトのよりよい共生社会の実現にむけた取り組みもおこなっています。
