What Types of Sound Experiences Enable Children to Learn Best?

At Northwestern’s Auditory Neuroscience Lab, Kraus and colleagues measure how the brain responds when various sounds enter the ear. They’ve found that the brain reacts to sound in microseconds, and that brain waves closely resemble the sound waves.
Making sense of sound is one of the most “computationally complex” functions of the brain, Kraus said, which explains why so many language and other disorders, including autism, reveal themselves in the way the brain processes sound. The way the brain responds to the “ingredients” of sound—pitching, timing and timbre—is a window into brain health and learning ability.

practical suggestions for creating space “activities that promote sound-to-meaning development,” whether at home or in school:
Reduce noise. Chronic background noise is associated with several auditory and learning problems: it contributes to “neural noise,” wherein brain neurons fire spontaneously in the absence of sound; it reduces the brain’s sensitivity to sound; and it slows auditory growth.
Read aloud. Even before kids are able to read themselves, hearing stories told by others develops vocabulary and builds working memory; to understand how a story unfolds, listeners, need to remember what was said before.
Encourage children to play a musical instrument. “There is an explicit link between making music and strengthening language skills, so that keeping music education at the center of curricula can pay big dividends for children’s cognitive, emotional, and educational health.Two years of music instruction in elementary and even secondary school can trigger biological changes in how the brain processes sound, which in turn affects language development.
Listen to audiobooks and podcasts. Well-told stories can draw kids in and build attention skills and working memory. The number and quality of these recordings has exploded in recent years, making it that much easier to find a good fit for individuals and classes.
Support learning a second language. Growing up in a bilingual environment causes a child’s brain to manage two languages at once.
Avoid white noise machines. In an effort to soothe children to sleep, some parents set up sound machines in bedrooms. These devices, which emit “meaningless sound,” as Kraus put it, can interfere with how the brain develops sound-processing circuitry.
Use the spread of technology to your advantage. Rather than bemoan the constant bleeping and chirping of everyday life, much of it the result of technological advances, welcome the new sound opportunities these developments provide. Technologies that shrink the globalized world enable second-language learning.

Rethinking Intelligence: How Does Imagination Measure Up?

http://ww2.kqed.org/mindshift/2016/04/11/rethinking-intelligence-how-does-imagination-measure-up

Dr. Scott Barry Kaufman When he was young, Kaufman had central auditory processing disorder, which made it hard for him to process verbal information in real time. He was asked to repeat third grade because he was considered a “slow” learner.

Kaufman thinks the traditional IQ test does a good job of measuring general cognitive ability, but says it misses all the ways that ability interacts with engagement. An individual’s goals within the learning classroom and excitement about a topic affect how he or she pursues learning, none of which is captured on IQ tests. Worse, those tests are often used to filter people in or out of special programs.

FOUR PRACTICES TO CULTIVATE CHILDREN’S CREATIVITY

  1. allowing more solitary reflective time in kids’ schedules. Whether it’s the constant demands on attention at school or in after-school activities, there often isn’t enough time in a child’s day when she can switch off the executive functioning network and tap into the imagination network.
  2. “We support obsessive passion, but not harmonious passion,” Kaufman said. He defines harmonious passion as a core part of people’s identity that makes them feel good about themselves. Harmonious passion is characterized by flexible engagement, where a child can abandon the pursuit if it isn’t paying dividends.
  3. give young kids a diverse set of experiences in order to increase the chances of inspiration. “Lots of things add meaning to our lives,” he said.
  4. educators, parents, and policymakers need to reset their mindsets around student ability. “Kids who think differently are not appreciated in our school system at all

it’s even worth measuring imagination, but Kaufman believes that measurement is important so researchers can see how changing behavior affects creative achievement. But he hopes the measurements are never used as another sorting mechanism.

My note: Kaufman makes a new call for an old trend. The futility of testing is raging across the United States K12 system. Higher education is turned into the last several decades (similarly to the United States health care system) into a cash cow. When the goal is profit, then good education goes down the drain. Cultivating children’s creativity cannot happen, when the foremost goals to make more money, which inevitably entails spending less cash (not only on teacher’s salaries).

“It’s a matter of finding balance,” he said. “Upgrade the technology skills of older ‘digital immigrants,’ and help young kids improve social skills.”

On one hand, we’re trained not to think deeply about subjects when we text quick snippets, Tweet short thoughts,
On the other hand, technology trains the brain to be nimble and to process new ideas quickly. We become more open to new ideas, and communicate more freely and frequently.
