...wanted to see passion. She was smart to ask for it. Gottman, Levenson and their colleagues found that gays and lesbians who exhibit more tension during disagreements are more satisfied with their relationships than those who remain unruffled. For straight people, higher heart rates during squabbles were associated with lower relationship satisfaction. For gays and lesbians, it was just the opposite. Gays conduct their relationships as though they are acting out some cheesy pop song: You have to make my heart beat faster for me to love you. For gays, it is apathy that murders relationships, not tension. Straight people...
After all, this wasn't the first time Bush had jumped to a wrong conclusion in the Middle East. Now his coalition of the willing is dwindling, oil prices are soaring, and the Arab street is angrier than ever. Bush's approval ratings are lower than Osama bin Laden's in Saudi Arabia...
...deep voice, also testosterone driven, can have similarly seductive power. Psychology professor David Feinberg of McMaster University in Ontario studied Tanzania's Hadza tribesmen, one of the world's last hunter-gatherer communities, and found that the richer and lower a man's voice, the more children he had. Researchers at the University of Albany recently conducted related research in which they had a sample group of 149 volunteers listen to recordings of men's and women's voices and then rate the way they sound on a scale from "very unattractive" to "very attractive." On the whole, the people...
...functional magnetic resonance imagers (fMRIs) show why it feels so good. The earliest fMRIs of brains in love were taken in 2000, and they revealed that the sensation of romance is processed in three areas. The first is the ventral tegmental, a clump of tissue in the brain's lower regions, which is the body's central refinery for dopamine. Dopamine does a lot of jobs, but the thing we notice most is that it regulates reward. When you win a hand of poker, it's a dopamine jolt that's responsible for the thrill that follows. When you look...
...poker game or the dinner table, after all. Something has to turn the exhilaration of a new partner into what can approach an obsession, and that something is the brain's nucleus accumbens, located slightly higher and farther forward than the ventral tegmental. Thrill signals that start in the lower brain are processed in the nucleus accumbens via not just dopamine but also serotonin and, importantly, oxytocin. If ever there was a substance designed to bind, it's oxytocin...
