One of the most important parts in the healthy development of a 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.

If you think American cooking means opening a package and throwing the contents into the microwave oven (微波炉), think again. On the one hand, it’s true that many Americans have cold cereal for breakfast, sandwiches for lunch and instant (方便的) dinners. From busy homemakers to working people, many Americans enjoy the convenience (方便) of fast food that can be ready to serve in 10 minutes or less. On the other hand, many Americans realize the importance of cooking skills. Parents — especially mothers — see the importance of training their children — especially daughters. Most Americans think that there’s nothing better than a good home-cooked meal. But with cooking, as with any other skill, good results don’t happen by accident.
Probably every cook has his or her own way of cooking. But there are some basic skills that most people follow. For example, baking is a main method (方法) of preparing food in America. For that reason, Americans would find it next to impossible to live without an oven. American cooks pay special attention to the balance of foods, too. In planning a big meal they try to include meat, a few vegetables, some bread and often a dessert. They also like to make sure the meal is colorful. Having several different colors of food on the plate usually makes for a healthy meal.
For those who need guidance in their cooking, or for those who have just run out of ideas, recipes are a great help. Recipes list all the ingredients for a dish (generally in the order used), the amount of each to use, and a description of how to put them together.
