The Dark Side of Oxytocin, University of Sydney Study

For a hormone, oxytocin is pretty famous. It's the "cuddle chemical" -- the hormone that helps mothers bond with their babies. Salespeople can buy oxytocin spray on the internet, to make their clients trust them. It's known for promoting positive feelings, but more recent research has found that oxytocin can promote negative emotions, too. The authors of a new review article in Current Directions in Psychological Science, a journal of the Association for Psychological Science, takes a look at what oxytocin is really doing. Oxytocin's positive effects are well known. Experiments have found that, in games in which you can choose to cooperate or not, people who are given more oxytocin trust their fellow players more.
