Mothers can still offer comfort, even from a distance, a new study has found. The results show that simply hearing their mothers’ voice over the phone works just as well at calming the nerves of stressed children as a real-life pat on the shoulder.
The soothing(抚慰的)effect is most likely due to the release of the hormone(荷尔蒙), oxytocin(催生素), in the brain, the researchers say. This “love hormone” is known to quell stress and is likely to be involved in social connections, including those between a mother and a child.
Previous work has revealed that this hormone is released during physical contact with a mother. “But it’s clear from these results that a mother’s voice can have the same effect as a hug, even if she isn’t actually standing there,” said the researcher, Leslie Seltzer, a biological scientist.
Seltzer tested a group of 61 girls, aged 7 to 12, by having them make an unprepared speech and solve a series of maths problems in front of a group of strangers, sending their hearts racing and levels of cortisol—a hormone associated with stress—soaring.
Facing a challenge like that raises stress levels of a lot of people. Once stressed, a third of the girls were comforted in person by their mothers with hugs. A third of the girls watched an emotionally neutral 75-minute video. The rest were handed a telephone with their mothers on the line.
For the girls who interacted in person or over the phone with their mothers, the levels of the “love hormone” rose significantly, and the stress-marking hormone was washed away. This effect didn’t show up for participants who watched the video.
Seltzer is now testing the amount of oxytocin released with other communication methods—like text messaging—and hopes to see the research spread out from human subjects. “It’s not just us, of course. Lots of very social species have voices,” she said. “on the one hand, we are curious to see if this effect is unique to humans. On the other, we’re hoping researchers who study vocal communication will consider looking at oxytocin release in other animals and apply it to broader questions of social behavior and evolutionary biology.

Happy birthday! Do birthday really make people happy? Of course they do.Birthday celebrate the day when we were born.Besides, that extra candle on the cake suggest another year of growth and maturity(成熟)—or so we hope.We all like to imagine that we are getting wiser and not just older.Most of us enjoy seeing the wonder of growth in others, as well.For instance, seeing our children develop and learn new things makes us feel proud.For Americans, like people in most cultures, growing up is a wonderful process.But growing old? That is a different story.
Growing old is not exactly for people in youth-oriented(以年轻人为中心)American culture.Most Americans like to look young, act young and feel young.As the old saying goes, “You’re young as you feel.” Older people joke about how many years young they are, rather than how many years old.People in some countries value the aged as a source of experience and wisdom.But Americans seem to favor those that are young, or at least “young at heart”.
Many older Americans find the “golden years” to be anything but golden.Economically, “senior citizens” often struggle just to get by.Retirement at the age of 65 brings a sharp decrease in personal income.Social security benefits usually cannot make up the difference.Older people may suffer from poor nutrition, medical care, and housing.Some even experience age discrimination(歧视).American sociologist Pat Moore once dressed up like an older person and wandered city streets.She was often treated rudely--even cheated and robbed.However, dressed as a young person, she received much more respect.
Unfortunately, the elderly population in America is increasing fast.Why? People are living longer.Fewer babies are being born.And middle-aged “baby boomers” are rapidly entering the group of the elderly.America may soon be a place where wrinkles(皱纹)are “in”.Marketing experts are ready noticing this growing group of consumer.
