The boundaries of cooperation: sharing and coupling from ethology to neuroscience

Cooperation is usually described as a human tendency to act jointly that involves helping, sharing, and acting prosocially. Nonetheless clues of cooperative actions can be found also in non-humans animals, as described in the first section of the present work. Even if such behaviors have been conventionally attributed to the research of immediate benefits within the animal world, some recent experimental evidence highlighted that, in highly social species, the effects of cooperative actions on others’ wellbeing may constitute a reward per se, thus suggesting that a strictly economic perspective can’t exhaust the meaning of cooperative decisions in animals. Here we propose, in the second section, that a deeper explanation concerning cognitive and emotional abilities in both humans and animals should be taken into account. Finally, the last part of the paper will be devoted to the description of synchronization patterns in humans within complex neuroscientific experimental paradigms, such as hyperscanning.
