Computers might not be clever enough to trick adults into thinking they are intelligent yet, but a new study, led by Javier' Movellan at the University of Califomia San Diego, shows that a giggling (咯咯笑的) robot is clever enough to get toddlers (初學走路者) to treat it as a peer (同齡人).
The researchers stationed a 2-foot-tall robot Called QRIO in a classroom of a dozen toddlers aged between 18 months and two years. QRIO stayed in the middle of the room using its sensors (傳感器) to avoid bumping (碰撞) into the kids. It was programmed to giggle when the kids touched its head, to occasionally sit down, and to lie down when its batteries died.
"We expected that after a few hours, the magic was going to disappear," Movellan says.  "That's what was found with earlier robots." But, in fact, the kids remained interested in the robot over several weeks, eventually communicating with QRIO in much the same way they did with other toddlers.
The researchers measured the relationship between the children and the robot in several ways. Firstly, as with other toddlers,  they touched QRIO mostly on the arms and hands, rather than on the face or legs. For this age group, "the amount of touching is a good predictor of how you are doing as a social being," Movellan says.
The children helped the robot up when it fell, and when QRIO's batteries ran out and it lay down, a toddler would come up and cover it with a blanket and say "night, night". However, when QRIO was programmed to spend all its time dancing, the kids quickly lost interest. When the robot went back to its old self, the kids treated it like a peer again.
"The study shows that current technology is very close to being able to produce robots able to develop a special relationship with toddlers," says Movellan. But, he adds, it is not clear yet whether robots can interest older children or adults in the same way.

All people need to sleep. Sleep is a necessary process that promotes proper body functioning and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.
Your bedroom should be shaped to your taste and to allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep. If your bedroom also functions as a command station for your life and work, the likelihood of your sleeping being poor is rather high. Bedrooms should be designed, decorated and used for mainly sleep. TVs, computers and other things should not be in your bedroom if at all possible.
Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before your sleep time. Develop a regular exercise program. Proper exercise and nutrition will help improve sleeping patterns. However, avoid exercising 2 hours before sleeping, since this may stimulate your body and make sleeping more difficult.
Establish a pre-bedtime rule that will help focus you on sleep. You can try meditation（沉思）,reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a specific category. Do what is the best for you.
Things such as room temperature, noise and light levels and even your bed mattress can have a lot of effect on the quality of sleep that you experience. Block out distracting noises and lights. You are in your bedroom to sleep and not be distracted by environmental interferences（干擾）.
