Outline of Research at the Start

自己利益を犠牲にせずに、他者と共に自己利益の最大化を可能とする相利的協働行為が協力的関係の形成にどのような役割を果たし、ヒトの利他性の生起にどのような影響を与えるのかを検討する。具体的には、相利的協働行為に含まれる、他者と共に同じ行動をとるという行動同期要因が重要なのか、それとも、互いにより大きな利益獲得を目指すという協働的意図要因が重要なのかを一連の実験室実験によって検討する。

Outline of Final Research Achievements

The puzzle of the evolution of cooperative behaviour in humans has been examined mainly in terms of dilemma situations. However, it has been pointed out that dilemma situations, such as exploiting or being exploited by others, do not account for a large proportion of human life history, and that 'mutualistic collaboration' situations, in which people help each other for mutual benefit, are more common. In the present study, a series of laboratory experiments were conducted to examine whether the behavioural synchronisation factor of taking the same action with others, which is included in mutualistic collaboration, is more important, or whether the collaborative intention factor of aiming for greater mutual benefit is more important. The results suggest that joint intention and symmetry of interests, which are included in mutualistic collaboration, are important factors.

Academic Significance and Societal Importance of the Research Achievements

ヒトが行う自己犠牲を伴う協力行動の維持は、単に他のメンバーと行動が一致したという事実の蓄積では達成されず、そうした同期を伴う行動が行動の同期を目指す意図のもと行われることや、相互に同様の利益をもたらすことが必要なことが示唆された。このことから、現実場面で集団への協力を引き出すためには、たとえば合唱や行進といった同期を伴う行動それのみでは不十分であり、その背景にある互いの意図やそうした行動から推測される利益の対称性等からの影響が重要である可能性が示された。
