Researchers shed light on how children learn to speak
Researchers have discovered that children under the age of two control speech using a different strategy than previously thought.
During the study at Queen's University, the researchers changed the vowel sounds that the participants heard over headphones as they talked. They found that while the adults and young children changed their vowel sounds in response to this altered feedback, the toddlers did not.
"We were very surprised to find that the two-year-olds do not monitor their own voice when speaking in the same way as adults do," says Ewen MacDonald, a former Queen's research associate and now associate professor at the Technical University of Denmark. "As they play music, violinists will listen to the notes they produce to ensure they are in tune. If they aren't, they will adjust the position of their fingers to bring the notes back in tune. When we speak, we do something very similar. We subconsciously listen to vowel and consonant sounds in our speech to ensure we are producing them correctly."
The researchers have proven that toddlers use a different strategy to control speech than adults. They still have not pinpointed the exact method children under two use when learning to control speech. Future studies are being developed to determine what strategy toddlers are using.
"Understanding the development of speech is a complex and challenging problem. Using novel techniques, such as the ones used in this experiment, we can isolate and better understand how the different components of speech develop," says Dr MacDonald. One possibility is that toddlers rely on the interaction with the person they are talking to in order to judge the accuracy of their speech sounds.
The research was recently published in Current Biology

Italian high-speed NTV Train
Passengers on board Italy's new Nuovo Trasporto Viaggiatori (NTV) trains might be forgiven for thinking of Ferrari cars at the sight of the low nose, the deep-red livery and the sleek interiors. The train interiors, styled by celebrated design house Italdesign Giugiaro, will offer three different classes of travel, with passengers offered the option to connect to tunnel-proof wireless Internet, watch TV or have meals served at their seat by staff trained in hospitality services. A fleet of 25 trains will link Turin in the north with Salerno in southern Italy, via Milan, Rome and Naples, as well as Venice with Rome, at a speed of 300 kilometres per hour, the maximum allowed speed on the Italian rail network. NTV plans to run up to 50 services a day as the first operator to use the AGV high-speed trains built by French transport and power engineering group Alstom.          |
Most of the Brain Cancer is Due to Cell Phones.
Cancer is one of the most dangerous Diseases in Action in this modern era.
Research Scientists Announced yesterday that Most Brain Cancers are Caused by Cell Phones. Among the worst is when we keep our mobiles below the pillow in vibration mode.
Scientist Stated Few Major:-
1. Going to talk long?? Use Headphones!!
2. Do not Keep Mobile Phones below the Pillow while Sleeping.
3. Use Left Ear Often.
