While long-term compatibility depends a lot on factors like status and life history, what causes the sparks to fly, or not, during that first conversation is how well your personality types match up.
Maybe that doesn't sound terribly scientific—but Fisher begs to differ.
She was one of the main speakers at the 20 TED conference. She appears in the 2014 documentary film about heart-break and loneliness, entitled Sleepless in New York Love can start with any of these three feelings, Fisher maintains.
Some people have sex with someone new and then fall in love. Some feel a deep feeling of attachment to another, which then turns into romance and the sex drive.
After sifting through an enormous pile of research literature, she concludes that four chemicals play leading roles in determining who we are and who we're drawn to: two sex hormones, testosterone and estrogen; and two neurotransmitters, dopamine and serotonin. she uses them as building blocks to construct four distinct personality types.
In Fisher's last book, Why We Love (2004), she broadly sketched out the influence of these molecules on our romantic lives. The Explorer, defined by high dopamine activity, is adventurous, novelty-seeking, creative.
By combining a variety of methodologies, her research on romantic relationships has continued to challenge conventional wisdom and shed new light on the intense human experiences of moving in, and out, of love. Fisher to ask her about her research and her thoughts on love and why she is optimistic about the future of marriage:[divider]Romantic love is not only a very strong addiction but a universal craving.
Just about 100 percent of all humans experience romantic love at some point.
A prominent public intellectual and active interdisciplinary scholar, her work has changed the way social and behavioral scientists think about the nuclear family and the reasons humans form pair-bond relationships.The Builder, with high serotonin activity, is cautious, conventional, managerial.The Director, pumped up with testosterone, is aggressive, single-minded, analytical.At its worst it leads to depression, suicide and even murder.In fact, our brain scanning studies (using f MRI) show that when a person is in love, they exhibit activity in the same brain regions that become active when one is addicted to cocaine and other drugs, including the nucleus accumbens and the ventral tegmental area (VTA), two primitive parts of the brain involved in the production and distribution of dopamine.That is not true of other addictions, such as gambling or substance abuse.
