Oxytocin is called the “love drug” or “love hormone” due to its increase when people form close intimate relationships. A recent study took 71 healthy men and women and gave them nasal spray oxytocin, waited two weeks, and gave them a placebo. They wanted to see how oxytocin affected social appraisal of their own and others’ close intimate relationship characteristics such as trust and closeness. Here is what they found: There was an oxytocin-induced increase in the positive appraisal of one's close intimate relationship characteristics. There was no oxytocin-induced increase in the positive appraisal of others’ close intimate relationship characteristics! This study adds further evidence to the mediating role of oxytocin in social cognition, specifically regarding romantic relationship characteristics.
