Writing out the same word again and again may bring back bad memories for some, but handwriting can boost connectivity across brain regions, some of which are involved in learning and memory, a new study shows.
In the study, psychologists Audrey and Ruud, both at the Norwegian University of Science and Technology, stuck electrodes(电极)on the participants' heads. They asked the participants to type out or handwrite with a digital pen words that appeared on a computer screen. Sensors in a cap recorded electrical brain activity. Then the psychologists looked for when two brain areas are active with the same frequency of electrical waves at the same time. This result can reveal the connectivity among different regions across the brain.
With handwriting, the researchers saw increased activity, specifically in low frequency bands, not only in the expected motor areas but also in others associated with learning. These low frequency bands have previously been shown to support memory processes. When the team compared the two tasks, they realized that handwriting—but not typing—increased the connectivity across parietal(顶叶)brain regions, which are involved in sensory and motor processing, and central regions, many of which are involved in memory. "Even when the movements are very similar, the activation seems much, much higher in handwriting," Audrey says. "It shows that there's more involvement of these brain regions when you're handwriting, which might give you some specific advantages."
These findings suggest that there are distinct processes of brain activation happening while a person types or writes. This boost of stimulation of handwriting facilitates learning because these particular waves between these areas are involved in memory formation and encoding(编码).
And although handwriting may help with learning processes, typing is often easier, faster and more practical. "Students and teachers alike should therefore consider the task at hand to decide to handwrite or type, "Audrey says. Despite the need for more studies to determine the best learning strategy, experts say that handwriting shouldn't be left behind in the digital age. "Schools need to bring in more writing into curriculum design," Ruud says.
First aid is a simple medical treatment that gives a person who suddenly becomes ill before a doctor can be found. It's believed that four hundred and eighty seconds after an accident can make a difference between life and death. {#blank#}1{#/blank#} Here are some different situations where you can learn, how to give first aid.
Burns
{#blank#}2{#/blank#} It's the best to place burns under softly running water for about 10 minutes. Remember that don't use ice!
Nosebleed
Ask the person to lean forward and pinch the nose for five to six minutes. {#blank#}3{#/blank#} If so, the blood may run into the mouth.
Dog Bites
Wash the bite with plenty of water at a comfortable temperature. {#blank#}4{#/blank#} Then, go to see the doctor at once and follow their suggestions carefully.
Chocking (窒息)
Stand behind the chocking person put your arms around his body and lean him or her forward slowly. Press his or her stomach. {#blank#}5{#/blank#} You can also hit his back with your hand.
A. Cool the burned area quickly with cool water. B. Have you done these in your daily life? C. This helps clean the dirty things around. D. This is why learning first aid is so important in our daily life. E. Don't raise the head! F. Do this up to five times. |
