Very informational article about music and the correlation with childhood development. "Music is a way of knowing." Music must be included in early childhood to ensure a comprehensive learning experience. 

Childhood language acquisition can be affected by the development of cognitive capabilities and interactions.

A 2013 joint study, conducted by the Montreal Neurological Institute and Hospital -- The Neuro at McGill University and Oxford University, concludes that the pattern of brain development is similar if you learn one or two languages from birth. However, learning a second language later on in childhood, after gaining proficiency in the first (native) language, does in fact, modify the brain's structure, specifically the brain's inferior frontal cortex. The left inferior frontal cortex became thicker and the right inferior frontal cortex became thinner. The cortex is a multi-layered mass of neurons that plays a major role in cognitive functions such as thought, language, consciousness and memory. The study suggests that the task of acquiring a second language after infancy stimulates new neural growth and connections among neurons in ways seen in acquiring complex motor skills such as juggling. The study's authors speculate that the difficulty that some people have in learning a second language later in life could be explained at the structural level. "The later in childhood that the second language is acquired, the greater are the changes in the inferior frontal cortex," said Dr. Denise Klein, researcher in The Neuro's Cognitive Neuroscience Unit and a lead author on the paper published in the journal Brain and Language. "Our results provide structural evidence that age of acquisition is crucial in laying down the structure for language learning."

Dr. Michael Rich is the director of the Center on Media and Child Health and the Clinic for Interactive Media and Internet Disorders. Rich notes some major takeaways: 1.Babies' brains are elastic: the first three years of life are critical for both language and overall brain development. Unlike other animals, humans are born with embryonic brains, rendering babies helpless and in need of caregivers while also providing a developmental advantage: allowing us to build our brains in response to the challenges and stimuli of the environment we're in," In the first three years of life, the brain triples in volume due to synaptic connections, therefore stimuli and challenges babies receive within that time frame help babies build creative, flexible and resilient brains. 2. Face to face interaction is valuable. 3. It's not just about screen time duration, but the type of content being consumed. For example, young children can interact meaningfully via Facetime, if they've previously interacted with that person. However, screens as a distraction for kids in lieu of human interaction= not good.

This article talks about how screen time affects babies language development. The first nine months of a baby's life are important for a child to understand sounds and how they should be used. They are able to understand language much earlier than they actually start talking. Many doctors and scientists encourage parents to communicate with their babies as soon as possible to develop language. Recent studies found that babies that spent more time in front of a screen than talking suffered in language development. I found it interesting that not all screen time is necessarily bad for a child's language development. For example, FaceTime can be beneficially for children because they are interacting in a meaningful way but using screens as a distraction for kids can be harmful.

When children start studying music before the age of seven, they develop bigger vocabularies, a better sense of grammar and a higher verbal IQ. These advantages benefit both the development of their mother tongue and the learning of foreign languages. During these crucial years, the brain is at its sensitive development phase, with 95% of the brain's growth occurring now. Music training started during this period also boosts the brain's ability to process subtle differences between sounds and assist in the pronunciation of languages - and this gift lasts for life, as it has been found that adults who had musical training in childhood still retain this ability to learn foreign languages quicker and more efficiently than adults who did not have early childhood music training. Humans first started creating music 500,000 years ago, yet speech and language was only developed 200,000 years ago. Evolutionary evidence, as interpreted by leading researchers such as Robin Dunbar from Oxford University, indicates that speech as a form of communication has evolved from our original development and use of music. This explains why our music and language neural networks have significant overlap, and why children who learn music become better at learning the grammar, vocabulary and pronounciation of any language.

This site is very insightful as to the differences in language development in the brain between those that learn a second language in childhood and those that learn the language as adults. It explains briefly the idea of a critical period and discusses the interesting aspects that come along with learning a second language later in life. It mentions Broca's and Wernicke's area.

"'Even in late gestation, babies are doing what they'll be doing throughout infancy and childhood - learning about language,' said the lead author." This reminds me of the study that showed that babies' crying melodies reflect their native languages. (http://news.bbc.co.uk/2/hi/health/8346058.stm)

Scientists say Koshik, an Asian elephant at a South Korean zoo, can imitate human speech, saying five Korean words readily understood by people who speak the language. The male elephant invented an unusual method of sound production that involves putting his trunk in his mouth and manipulating his vocal tract. Vocal mimicry is not a common behavior of mammals (unless you count humans). Researchers postulate Koshik was apparently so driven to imitate sounds that he invented the method of putting his trunk in his mouth and moving it around. They believe that he may have done this to bond with his trainers, as he was deprived of elephant companionship during a critical period of his childhood and spent years with humans as his only social contact. A video of Koshik with his trainer is embedded in the article.

Brain imaging studies have explored the neural mechanisms of recovery in adults following acquired disorders and, more recently, childhood developmental disorders. However, the neural systems underlying adult rehabilitation of neurobiologically based learning disabilities remain unexplored, despite their high incidence. Here we characterize the differences in brain activity during a phonological manipulation task before and after a behavioral intervention in adults with developmental dyslexia. Phonologically targeted training resulted in performance improvements in tutored compared to nontutored dyslexics, and these gains were associated with signal increases in bilateral parietal and right perisylvian cortices. Our findings demonstrate that behavioral changes in tutored dyslexic adults are associated with (1) increased activity in those left-hemisphere regions engaged by normal readers and (2) compensatory activity in the right perisylvian cortex. Hence, behavioral plasticity in adult developmental dyslexia involves two distinct neural mechanisms, each of which has previously been observed either for remediation of developmental or acquired reading disorders.

Children learn language and literacy skills best during powerful, high-quality conversations with the important adults in their lives. Learn what the ingredients of a powerful conversation are, and get specific tips for what you can do during these conversations to build the important skills your child needs to learn.

"In recent decades, the study of language acquisition and instruction has increasingly focused on "chunking": how children learn language not so much on a word-by-word basis but in larger "lexical chunks" or meaningful strings of words that are committed to memory ... A native speaker picks up thousands of chunks like "heavy rain" or "make yourself at home" in childhood, and psycholinguistic research suggests that these phrases are stored and processed in the brain as individual units."

Good find, Ryan! I also took the video link and embedded it into our moodle page.

This article talks about how difficult it really is to learn a second language. It further explains the different stages our brain goes through and how our brain's plasticity goes down as we age. The article also talks about psychologists who disagree on when the "critical period" of learning a second language takes place.

A longitudinal study conducted by USC suggests that music training during childhood, even for a period as brief as two years, can accelerate brain development and sound processing. We believe that this may benefit language acquisition in children given that developing language and reading skills engage similar brain areas.

What does recent research say about the potential benefits of bilingual education? Here are the main 6 findings: 1. Attention: "[Bilinguals] can pay focused attention without being distracted and also improve in the ability to switch from one task to another," says Sorace. Do these same advantages accrue to a child who begins learning a second language in kindergarten instead of as a baby? We don't yet know. Patterns of language learning and language use are complex. But Gigi Luk at Harvard cites at least one brain-imaging study on adolescents that shows similar changes in brain structure when compared with those who are bilingual from birth, even when they didn't begin practicing a second language in earnest before late childhood. 2. Empathy: bilingual children as young as age 3, because they must follow social cues to figure out which language to use with which person and in what setting, have demonstrated a head start on tests of perspective-taking and theory of mind - both of which are fundamental social and emotional skills. 3. Reading (English): students enrolled in dual-language programs outperformed their peers in English-reading skills by a full school year's worth of learning by the end of middle school. 4. School performance and engagement: compared with students in English-only classrooms or in one-way immersion, dual-language students have somewhat higher test scores and also seem to be happier in school. Attendance is better, behavioral problems fewer, parent involvement higher. 5. Diversity and integration: Because dual-language schools are composed of native English speakers deliberately placed together with recent immigrants, they tend to be more ethnically and socioeconomically balanced. And there is some evidence that this helps kids of all backgrounds gain comfort with diversity and different cultures. 6. Protection against cognitive decline and dementia: actively using two languages seems to have a protective effect against age-related demen

According to science and psychology, the easiest time to learn a second language is during childhood. This is because the brain at that age is a sponge for absorbing new information. Also children are more eager to learn than adults and they have more time for it. In general, all learning becomes harder with age.

Nice overview of the neurological and other benefits conferred by bilingualism. Being fluent in two languages, particularly from early childhood, not only enhances a person's ability to concentrate, but might also protect against the onset of dementia and other age-related cognitive decline. More recently, scientists have discovered that bilingual adults have denser gray matter (brain tissue packed with information-processing nerve cells and fibers), especially in the brain's left hemisphere, where most language and communication skills are controlled. The effect is strongest in people who learned a second language before the age of five and in those who are most proficient at their second language. This finding suggests that being bilingual from an early age significantly alters the brain's structure.
