Early hardship may shape how oxytocin influences altruism
While humans are inherently social beings, they can interact and connect with others in very different ways. For instance, while some people tend to be more altruistic, others are less prone to helping their friends, acquaintances or even complete strangers, particularly when it comes at a personal cost.
A new study suggests that early-life experiences may influence how oxytocin, often called the "love hormone," affects altruistic behavior in adults. Researchers from the University of Oldenburg, the University of Bonn and other institutes found that oxytocin has different effects on altruism depending on an individual's childhood adversity.
Participants who reported greater childhood hardships showed an increase in altruistic behavior after receiving oxytocin, while those with fewer early-life challenges made fewer altruistic donations. The study, published in Translational Psychiatry, highlights the importance of considering an individual's developmental history and neurobiology when examining human social behavior.
