Washington, November 7 : Ever wonder what drives us to donate money for a good cause or financially helping out a person in need? Well, researchers at Claremont Graduate University say the answer may lie in oxytoxin, a mammalian hormone involved in social recognition and bonding.

Neuroeconomist Paul J. Zak and his colleagues gave doses of oxytocin and a placebo to participants, who were then offered a blinded, one-time decision on how to split a sum of money with a stranger who could accept or reject the split.

Participants who were administered oxytocin offered 80 per cent more money than those given a placebo, they found.

According to Zak, the findings indicate that though humans are inherently altruistic, they are also generous when they feel empathy toward one another.
