Dr. Amy Banks, JBMTI's director of advanced training, has long been touting the ce
ntral role of oxytocin, often called "the love drug," in connection and relational neurobiology. Two recent reports delve into the complexities of the drugs affects on human behavior.
Boston's WCVB-TV featured the story, 'Cuddle Drug' May Help Couples Bond, highlighting a new treatment of doctors giving patients "small tables that contain oxytocin" to increase feelings of intimacy. The report quotes Dr. Matt French of Wellness Solutions in Phoenix, "If a couple is struggling with bonding issues, with intimacy issues, it could be as a result of inadequate levels of the hormone oxytocin."
On the flip side, a January 11, 2011 piece in The New York Times, Depth of the Kindness Hormone Appears to Know Some Bounds, clarifies that oxytocin is not a universal answer to better connection among all people or to world peace. According to the article, Dr. Carsten K. W. De Dreu, a psychologist at the University of Amsterdam, decided to take a closer look at oxytocin after, "he decided on evolutionary principles that no one who placed unbounded trust in others could survive." His experiment found oxytocin to produce ethnocentric behavior, and to create "intergroup bias primarily because it motivates in-group favoritism and because it motivates out-group derogation."
What does it mean that a chemical basis for ethnocentrism is embedded in the human brain? “In the ancestral environment it was very important for people to detect in others whether they had a long-term commitment to the group,” Dr. De Dreu said. “Ethnocentrism is a very basic part of humans, and it’s not something we can change by education. That doesn’t mean that the negative aspects of it should be taken for granted.”
Bruno B. Averbeck, an expert on the brain’s emotional processes at the National Institute of Mental Health, said that the effects of oxytocin described in Dr. De Dreu’s report were interesting but not necessarily dominant. The brain weighs emotional attitudes like those prompted by oxytocin against information available to the conscious mind. If there is no cognitive information in a situation in which a decision has to be made, like whether to trust a stranger about whom nothing is known, the brain will go with the emotional advice from its oxytocin system, but otherwise rational data will be weighed against the influence from oxytocin and may well override it, Dr. Averbeck said.
Dr. Averbeck said he was amazed that a substance like oxytocin can affect such a high-level human behavior. “It’s really surprising to me that this neurotransmitter can so specifically affect these social behaviors,” he said. - NY Times article excerpt
Both reports confirm the importance of relational neuroscience research in understanding the role of the brain and its neurotransmitters in affecting human and social behavior.
