Well by measuring oxytocin we found that the more money the second person received, the more their brain produced oxytocin, and the more oxytocin on board, the more money they returned.
Dengan mengukur kadar oksitosin kami menemukan bahwa semakin banyak uang yang diterima orang kedua semakin banyak otak mereka menghasilkan oksitosin dan semakin banyak oksitosin, semakin banyak uang yang dikembalikan.
