An infant's mother tongue creates neural patterns that the unconscious brain retains years later, even if the child totally stops using the language, (as can happen in cases of international adoption) according to a new joint study by scientists at the Montreal Neurological Institute and Hospital. The study offers the first neural evidence that traces of the "lost" language remain in the brain and suggests that early-acquired information is not only maintained in the brain, but unconsciously influences brain processing for years, perhaps for life -- potentially indicating a special status for information acquired during optimal periods of development. This could counter arguments not only within the field of language acquisition, but across domains, that neural representations are overwritten or lost from the brain over time.

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.

The South has various species of both accents and dialects. An accent is composed purely of pronunciation changes, almost always vowel sounds. Dialects, on the other hand, incorporate all kinds of other stuff, including vocabulary, structure, syntax, idioms, and tenses. There were many distinct regional accents or dialects in the pre-Civil War South. North Carolina, smack in the middle of the Atlantic South, found more of those dialects within its borders than any other state. On top of that, North Carolina is home to a dialect found nowhere else in the world: the English spoken by those in the Pamlico Sound region, the coastal area that includes the Outer Banks. Interesting trivia tidbit: Distinctly Southern dialects among the white population of the American South seem only to have taken hold starting around the time of the Civil War.The period from the end of the Civil War until World War I-which seems like a long time, but is very condensed linguistically, less than three generations-saw an explosion of diversity in what are sometimes referred to as Older Southern American Accents. The article also notes the reasons for the South's linguistic diversity in re: accents and dialects, and why those accents and dialects have been perpetuated. In Southern states bordering the Atlantic Ocean, regional dialects sprung up seemingly overnight, influenced by a combination of factors, including the destruction of infrastructure, the panic of Reconstruction, lesser-known stuff like the boll weevil crisis, and the general fact that regional accents tend to be strongest among the poorest people. In the post-Civil War period, Southerners left the South en masse; the ones who stayed were often the ones who couldn't afford to leave, and often the keepers of the strongest regional accents. A lack of migration into the South, either from the North or internationally, allowed its regional accents to bloom in relative isolation. However, after WWII, an influx of Northerne

This article is about when a child needs to learn a language to be able to sound like a native. This article closely relates to what we have been learning in class and talks about the critical period. It talks about the critical period in a person's life for learning a new language and that is when a child should learn in order to sound like a native.

Researchers from Brown University and King's College London have uncovered new details about how brain anatomy influences language development in young kids. Using advanced MRI, they find that different parts of the brain appear to be important for language development at different ages. Their study, published in the Journal of Neuroscience, found that the explosion of language acquisition that typically occurs in children between 2 and 4 years old is not reflected in substantial changes in brain asymmetry. Structures that support language ability tend to be localized on the left side of the brain. For that reason, the researchers expected to see more myelin -- the fatty material that insulates nerve fibers and helps electrical signals zip around the brain -- developing on the left side in children entering the critical period of language acquisition. Surprisingly, anatomy did not predict language very well between the ages of 2 and 4, when language ability increases quickly. "What we actually saw was that the asymmetry of myelin was there right from the beginning, even in the youngest children in the study, around the age of 1," said the study's lead author, Jonathan O'Muircheartaigh, the Sir Henry Wellcome Postdoctoral Fellow at King's College London. "Rather than increasing, those asymmetries remained pretty constant over time." That finding, the researchers say, underscores the importance of environment during this critical period for language. While asymmetry in myelin remained constant over time, the relationship between specific asymmetries and language ability did change, the study found. To investigate that relationship, the researchers compared the brain scans to a battery of language tests given to each child in the study. The comparison showed that asymmetries in different parts of the brain appear to predict language ability at different ages. "Regions of the brain that weren't important to successful language in toddlers became more important i

If you're looking for the species that most closely matches our linguistic prowess, surprisingly, you won't find it in the apes, the primates, or even in the mammals. You have to travel to a far more distant relative, all the way to a family of birds known as the songbirds. The vocal life of a songbird is similar to ours in many ways. They learn songs by imitating their elders. Like human speech, these songs are passed down from one generation to the next. Songbirds are also best equipped to learn songs in their youth, and they have to practice to develop their ability. They can improvise and string together riffs into new songs, and over generations these modified songs can turn into new dialects. And like us, they come hard-wired with 'speech-centers' in their brain that are dedicated to language processing. An experiment from 2009 by Fehér and colleagues took newly hatched songbirds of the zebra finch species and raised them in sound proof chambers. They did this during their critical period of language development. Surprisingly, this culturally isolated generation of birds began to develop their own songs. These songs were less musical than your typical songbird song - they had irregular rhythms, they would stutter their notes, and the notes would sound more noisy. But the researchers were curious where this would lead. They listened to the songs of the next few generations of pupils, the offspring of these children of silence. What they found was quite amazing. In just two generations, the songs started to change in unexpected ways - they were becoming more musical. In fact, they started to converge upon the song of the wild songbirds, even though none of these birds had ever heard the wild songs. The Feher study suggests, but does not prove, that songbirds must have an innate understanding of the structures of their language. In other words, they seem to have a built-in intuition about grammar. Over time, they may be using these intuitions to develo

The takeaway: one K is bad, two Ks are good and above all else, never, ever use three Ks. 1. "Okay" is obviously the most professional way to type the word, and I will vouch that it is also safe to casually use in text messages. Some disagree that "okay" can sound sarcastic or stern, especially when paired with a period. Which isn't wrong - sentences do invoke a more serious tone when there are periods involved. But the reason why okay is, well, okay, is because it's the longest form of the word. You took the time to type out those additional two letters, and that counts for something. 2. "Kk" is the closest to gotcha. It means message received, roger that. 3. The origins of the dreadful "k" can't exactly be pinpointed, though it's been a thing since iMessage looked like this, so basically the Stone Age. People voiced their disdain for short responses - "k, ok, lol" - on Facebook pages and through memes years ago. And everyone pretty much agreed that yeah, when you type out an extremely long, emotionally charged paragraph to someone and they respond with one letter, it's pretty infuriating. From then on we've been conditioned (or traumatized) to react in a similar manner to the single k. Even when it's just in response to a simple, harmless sentence, it can still feel like a dig.

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.

"Teenagers are more susceptible to developing disorders like addiction and depression ... "The brain region traditionally associated with reward and motivation, called the nucleus accumbens, was activated similarly in adults and adolescents," said Moghaddam. "But the unique sensitivity of adolescent DS to reward anticipation indicates that, in this age group, reward can tap directly into a brain region that is critical for learning and habit formation." ... not only is reward expectancy processed differently in an adolescent brain, but also it can affect brain regions directly responsible for decision-making and action selection. ... "Adolescence is a time when the symptoms of most mental illnesses-such as schizophrenia and bipolar and eating disorders-are first manifested, so we believe that this is a critical period for preventing these illnesses," Moghaddam said."

Can babies learn to read? While parents use DVDs and other media in an attempt to teach their infants to read, these tools don't instill reading skills in babies, a study by researchers at New York University's Steinhardt School of Culture, Education, and Human Development has found. In their study, which appears in the Journal of Educational Psychology, the researchers examined 117 infants, aged nine to 18 months, who were randomly assigned to treatment and control groups. Children in the treatment condition received a baby media product, which included DVDs, word and picture flashcards, and flip books to be used daily over a seven-month period; children in the control condition did not receive these materials from the researchers. Over the course of seven months, the researchers conducted a home visit, four laboratory visits, and monthly assessments of language development. To test children's emerging skills in the laboratory, the researchers examined the capacity to recognize letter names, letter sounds, vocabulary, words identified on sight, and comprehension. A combination of eye-tracking tasks and standardized measures were used to study outcomes at each stage of development. Using a state-of-the art eye-tracking technology, which follows even the slightest eye movements, the researchers were able to closely monitor how the infants distributed their attention and how they shifted their gaze from one location to another when shown specific words and phrases. No discernible differences were observed between the results of the experimental group vs. the control; yet parents of the infants in the experimental group perceived that their children were, in fact, acquiring words. :-)

""When two people start a conversation, they usually begin talking alike within a matter of seconds," says James Pennebaker. ... If the essay question was asked in a dry, confusing way, the students answered accordingly. If asked in a flighty, "Valley girl" way, the students punctuated their answers with "like," "sorta" and "kinda."... "Style words in the spouses' poems were more similar during happier periods of their relationships and less synchronized toward each relationship's end," Ireland says." Unfortunately, the paper isn't online, but you can see the abstract: http://www.ncbi.nlm.nih.gov/pubmed/20804263

Thanks, Ryan. I think there will be a lot of interest in this research.

This was interesting because the children speak their own animal language.

Strange but true story with interesting connections to the "Genie" case and the critical period hypothesis. In 2008, in Amstedten, Austria, two brothers, age 5 and 18, were discovered. They were being held captive in a cellar with their mother. The boys use animalistic noises rather than words to communicate with each other. Other than their mother, age 42, who'd lost most of her reading and writing skills after being imprisoned 24 years ago, their only source of linguistic input was a TV. A police officer who met the two boys noted they communicate with noises that are a mixture of growling and cooing. "If they want to say something so others understand them as well they have to focus and really concentrate, which seems to be extremely exhausting for them."

This study investigated the effects of training in /r/-/l/ perceptual identification on /r/-/l/ production by adult Japanese speakers. Subjects were recorded producing English words that contrast /r/ and /l/ before and after participating in an extended period of /r/-/l/ identification training using a high-variability presentation format.

For the first time we have lowered a microphone into the Challenger Deep, the deepest known ocean trench. It picked up some surprising noises. Taken over a three week period in July 2015, these recordings provided a never before seen profile of the sounds of the deep.

This article done talks about how children with autism have their "critical period" of language learning affected. Research was done through observation through an EEG which monitored babies of multiple age groups, specifically their auditory cortex.

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.

Of course, had she inserted too many marks, that may have been a problem, too, as there is suddenly a very fine line between appearing overeager (too much punctuation) and dismissive (not enough). Even the period, once the most benign of the punctuation spectrum, now feels aggressive.

This article talks about how with our changing world is dealing with new ways of communication.

Quick comparison of the differences between child and adult second language learning: suggests that children will be able to attain greater fluency in L2, whereas adults will learn the L2 imperfectly.

This article talked compared the learning of language between adults and children. There were various studies that took place in this article. They concluded that there was an age cutoff at 17 to learn a new language. They also talked about when the "critical period" is. Overall, they compared age with how well the person could pick up the language.
