Preschool children show upward reactions to the pompous senseless words – ScienceDaily


Of all our senses, hearing is the only one that has long been suspected of being "still" – even in our sleep. The sounds that occur during the night have a way to register into the brain. Now, a group of researchers in Tennessee reports the results of studies about what is heard and heard during sleep, and what it can mean for brain development.

At the upcoming 176th meeting of the Acoustical Society of America, held in Canada on 20-19 May, November at the Victorian Conference Center in Victoria, in collaboration with Canada's Acoustics Week 2018 Acoustics Week in Canada, will present a team of Vanderbilt scientists abstract and preliminary results from an EEG study in which preschool children showed footprints for the sounds heard during the tension.

The work of the group is one of the first attempts at how the sleep environment affects children of preschool age.

"The type of environment in which children are asleep has been a topic of conversation, especially in recent years," says Adrienne Roman, author of the abstract. "But there is a big hole in the literature and a discussion about what's going on with pre-school children, which was our leaps."

To study the brainwaves of young children, the researchers used a portable EEG and tested individual children in a quiet, isolated room while drinking at a university school. As soon as he slept, the group briefly gave the child three absurd words.

Children showed positive signs for recognizing test sounds in a set of other nonsense words (which they had not heard before) in the post-EEG post-nap. It means that while they were asleep, the children were still processing their hearing information.

One of the new features of the group study was that they were able to verify that the kids were really asleep before the sounds – it is not an easy exercise for some of the youngest participants.

"Of course they're tired and ready for their nap, and now you're trying to connect them to this facility and a few of them did not."

Roman hopes that work is the first step to understanding how these processes work in children who use hearing technology for hearing loss, but for the convenience of removing sleeping appliances. The group collected EEG data in one child who used a cochlear implant that provided the possibility of sleeping with one on, and plans to get other children with implants.
