Prescriptivists cannot point to a single language that became unusable or inexpressive as a result of people’s failure to uphold traditional vocabulary and grammar. Every language existing today is fantastically expressive

Nonetheless, despite potential harm done by an individual word’s change in meaning, cultures tend to have all the words they need for all the things they want to talk about.

Every language has a characteristic inventory of contrasting sounds, called phonemes.

The answer is that language is a system. Sounds, words and grammar do not exist in isolation: each of these three levels of language constitutes a system in itself.

During the Great Vowel Shift, ee and oo started to move towards the sounds they have today. Nobody knows why

Words also weaken with frequent use

At the level of grammar, change might seem the most unsettling, threatening a deeper kind of harm than a simple mispronunciation or new use for an old word

what are the objects without those crucial case endings? The answer is boring: word order

Language is self-regulating. It’s a genius system – with no genius

"This study will likely bring new attention in the field to the ways in which circuits like this, widely considered a 'simple' one, are in fact highly complex and subject to modulatory influence like higher regions of the brain,"

Additionally, they describe novel anatomical projections that provide acetylcholine input to the MNTB.

"You can think of this modulation as akin to shifting an antenna's position to eliminate static for your favorite radio station."

the researchers identified for the first time a set of completely unknown connections in the brain between the modulatory centers and this important area of the auditory system.

understanding how other sensory information is processed in the brain.

that not only the cerebral cortex, but the entire auditory pathway, represents sounds according to prior expectations.

Although participants recognised the deviant faster when it was placed on positions where they expected it, the subcortical nuclei encoded the sounds only when they were placed in unexpected positions.

Predictive coding assumes that the brain is constantly generating predictions about how the physical world will look, sound, feel, and smell like in the next instant, and that neurons in charge of processing our senses save resources by representing only the differences between these predictions and the actual physical world.

e have now shown that this process also dominates the most primitive and evolutionary conserved parts of the brain. All that we perceive might be deeply contaminated by our subjective beliefs on the physical world."

Developmental dyslexia, the most wide-spread learning disorder, has already been linked to altered responses in subcortical auditory pathway and to difficulties on exploiting stimulus regularities in auditory perception.

During speech perception, our brain integrates information from our ears with that from our eyes. Because this integration happens early in the perceptual process, visual cues influence what we think we are hearing. That is, what we see can actually shape what we "hear."

When visual information clashes with that from sound, sensory crosstalk can cause what we see to alter what we hear

Perceptual systems, particularly smell, connect with memory and emotion centers to enable sensory cues to trigger feelings and recollections, and to be incorporated within them

What might life be like if you had synesthesia? Here is one artist's rendition of the experience of a synaesthete. In this surreal world, music records smell like different colors, foods tastes like specific noises, and sound comes in all varieties of textures and shapes

Our brain is hard wired to make sense.

our brain works in a way if it doesn’t understand what the eyes perceive or “see” it makes a picture for us.

The strange thing is, our minds are wired to hear and see things that make sense, like hearing words or talking due to fluctuations in sound itself.

Not everything we hear or see is paranormal. Sadly as a researcher you’ll deal with some individuals that think everything is spirit, but that is far from “reality.”

Many individuals use white noise to sleep; it is very common for people to use fans and white noise machines, these are the most common source and they’re very popular.

Noise is classified by different colours, each is made up of different sound properties and frequencies.

While there’s isn’t significant evidence in humans to suggest that lower-volume sound like background white noise could bring about these kinds of changes in the central auditory system, Attarha’s team cite animal studies that suggest prolonged exposure in animals does affect their brains.

Children learn different communication, language and literacy skills through a structure of literacy framework that are related to development.

The process tries to make children to enjoy communication, language and literacy and be enthusiastic about the learning it .

They develop understanding of the correspondence between spoken and written sounds and learn to link sounds and letters and use their knowledge to read and write simple words by sounding out and blending.

People believe that memory should be effortless, but their expectations for how much they should remember are totally out of whack with how much they’re capable of remembering.1

What is the most common misconception about memory?

Another misconception is that memory is supposed to be an archive of the past. We expect that we should be able to replay the past like a movie in our heads.

we don’t replay the past as it happened; we do it through a lens of interpretation and imagination.

How much are we capable of remembering, from both an episodic2 2 Episodic memory is the term for the memory of life experiences. and a semantic3 3 Semantic memory is the term for the memory of facts and knowledge about the world. standpoint?

I would argue that we’re all everyday-memory experts, because we have this exceptional semantic memory, which is the scaffold for episodic memory.

If what we’re remembering, or the emotional tenor of what we’re remembering, is dictated by how we’re thinking in a present moment, what can we really say about the truth of a memory?

But if memories are malleable, what are the implications for how we understand our “true” selves?

your question gets to a major purpose of memory, which is to give us an illusion of stability in a world that is always changing. Because if we look for memories, we’ll reshape them into our beliefs of what’s happening right now. We’ll be biased in terms of how we sample the past. We have these illusions of stability, but we are always changing

And depending on what memories we draw upon, those life narratives can change.

I know it sounds squirmy to say, “Well, I can’t answer the question of how much we remember,” but I don’t want readers to walk away thinking memory is all made up.

One thing that makes the human brain so sophisticated is that we have a longer timeline in which we can integrate information than many other species. That gives us the ability to say: “Hey, I’m walking up and giving money to the cashier at the cafe. The barista is going to hand me a cup of coffee in about a minute or two.”

There is this illusion that we know exactly what’s going to happen, but the fact is we don’t. Memory can overdo it: Somebody lied to us once, so they are a liar; somebody shoplifted once, they are a thief.

If people have a vivid memory of something that sticks out, that will overshadow all their knowledge about the way things work. So there’s kind of an illus

we have this illusion that much of the world is cause and effect. But the reason, in my opinion, that we have that illusion is that our brain is constantly trying to find the patterns

I think of memory more like a painting than a photograph. There’s often photorealistic aspects of a painting, but there’s also interpretation. As a painter evolves, they could revisit the same subject over and over and paint differently based on who they are now. We’re capable of remembering things in extraordinary detail, but we infuse meaning into what we remember. We’re designed to extract meaning from the past, and that meaning should have truth in it. But it also has knowledge and imagination and, sometimes, wisdom.

memory, often, is educated guesses by the brain about what’s important. So what’s important? Things that are scary, things that get your desire going, things that are surprising. Maybe you were attracted to this person, and your eyes dilated, your pulse went up. Maybe you were working on something in this high state of excitement, and your dopamine was up.

It could be any of those things, but they’re all important in some way, because if you’re a brain, you want to take what’s surprising, you want to take what’s motivationally important for survival, what’s new.

On the more intentional side, are there things that we might be able to do in the moment to make events last in our memories? In some sense, it’s about being mindful. If we want to form a new memory, focus on aspects of the experience you want to take with you.

If you’re with your kid, you’re at a park, focus on the parts of it that are great, not the parts that are kind of annoying. Then you want to focus on the sights, the sounds, the smells, because those will give you rich detail later on

Another part of it, too, is that we kill ourselves by inducing distractions in our world. We have alerts on our phones. We check email habitually.

When we go on trips, I take candid shots. These are the things that bring you back to moments. If you capture the feelings and the sights and the sounds that bring you to the moment, as opposed to the facts of what happened, that is a huge part of getting the best of memory.

this goes back to the question of whether the factual truth of a memory matters to how we interpret it. I think it matters to have some truth, but then again, many of the truths we cling to depend on our own perspective.

There’s a great experiment on this. These researchers had people read this story about a house.8 8 The study was “Recall of Previously Unrecallable Information Following a Shift in Perspective,” by Richard C. Anderson and James W. Pichert. One group of subjects is told, I want you to read this story from the perspective of a prospective home buyer. When they remember it, they remember all the features of the house that are described in the thing. Another group is told, I want you to remember this from the perspective of a burglar. Those people tend to remember the valuables in the house and things that you would want to take. But what was interesting was then they switched the groups around. All of a sudden, people could pull up a number of details that they didn’t pull up before. It was always there, but they just didn’t approach it from that mind-set. So we do have a lot of information that we can get if we change our perspective, and this ability to change our perspective is exceptionally important for being accurate. It’s exceptionally important for being able to grow and modify our beliefs

There are different types of attention, and they use different parts of the brain.

Hearing, in short, is easy. You and every other vertebrate that hasn’t suffered some genetic, developmental or environmental accident have been doing it for hundreds of millions of years. It’s your life line, your alarm system, your way to escape danger and pass on your genes

This simplest form of attention requires almost no brains at all and has been observed in every studied vertebrate.

But listening, really listening, is hard when potential distractions are leaping into your ears every fifty-thousandth of a second — and pathways in your brain are just waiting to interrupt your focus to warn you of any potential dangers.

Listening is a skill that we’re in danger of losing in a world of digital distraction and information overload.

we can train our listening just as with any other skill. Listen to new music when jogging rather than familiar tunes. Listen to your dog’s whines and barks: he is trying to tell you something isn’t right. Listen to your significant other’s voice — not only to the words, which after a few years may repeat, but to the sounds under them, the emotions carried in the harmonics.

“You never listen” is not just the complaint of a problematic relationship, it has also become an epidemic in a world that is exchanging convenience for content, speed for meaning. The richness of life doesn’t lie in the loudness and the beat, but in the timbres and the variations that you can discern if you simply pay attention.

The effectiveness of this process is so great that human brain is able to accurately identify words and whole phrases from a noisy background. This power of analysis brings to minds the great similarity between the brain and powerful supercomputers.

Functional imaging of the brain revealed that activated brain parts are different between native and non-native speakers. The superior temporal gyrus is an important brain region involved in language learning. For a native speaker this part is responsible for automated processing of lexical retrieval and the build of phrase structure. In native speakers this zone is much more activated than in non-native ones.

infants begin their lives with a very flexible brain that allows them to acquire virtually any language they are exposed to. Moreover, they can learn a language words almost equally by listening or by visual coding. This brain plasticity is the motor drive of the children capability of “cracking the speech code” of a language. With time, this ability is dramatically decreased and adults find it harder to acquire a new language.

clearly demonstrated that there are anatomical brain differences between fast and slow learners of foreign languages. By analyzing a group of people having a homogenous language background, scientists found that differences in specific brain regions can predict the capacity of a person to learn a second language.

Until the last decade few studies compared the language acquisition in adults and children. Thanks to modern imaging and electroencephalography we are now able to address this question.

Language acquisition is a long-term process by which information are stored in the brain unconsciously making them appropriate to oral and written usage. In contrast, language learning is a conscious process of knowledge acquisition that needs supervision and control by the person.

It's quite possible that our love of music was simply an accident. We originally evolved emotions to help us navigate dangerous worlds (fear) and social situations (joy). And somehow, the tones and beats of musical composition activate similar brain areas.

Nature Neuroscience, led by Zatorre, researchers found that dopamine release is strongest when a piece of music reaches an emotional peak and the listener feels "chills"— the spine-tingling sensation of excitement and awe.

"Music engages the same [reward] system, even though it is not biologically necessary for survival," says Zatorre.

Presumably, we evolved to recognize patterns because it's an essential skill for survival. Does a rustling in the trees mean a dangerous animal is about to attack? Does the smell of smoke mean I should run, because a fire may be coming my way?

Music is a pattern. As we listen, we're constantly anticipating what melodies, harmonies, and rhythms may come next.

That's why we typically don't like styles of music we're not familiar with. When we're unfamiliar with a style of music, we don't have a basis to predict its patterns

We learn through our cultures what sounds constitute music. The rest is random noise.

When we hear a piece of music, its rhythm latches onto us in a process called entrainment. If the music is fast-paced, our heartbeats and breathing patterns will accelerate to match the beat.

Another hypothesis is that music latches onto the regions of the brain attuned to speech — which convey all of our emotions.

"It makes sense that our brains are really good at picking up emotions in speech," the French Institute of Science's Aucouturier says. It's essential to understand if those around us are happy, sad, angry, or scared. Much of that information is contained in the tone of a person's speech. Higher-pitched voices sound happier. More warbled voices are scared.

Music may then be an exaggerated version of speech.

And because we tend to mirror the emotions we hear in others, if the music is mimicking happy speech, then the listener will become happy too.

But older females who have more offspring, and thus share more of the group’s genes, are more likely to cooperate by sharing food and knowledge.

She believes the primary reason women live so long after menopause is because they help improve the survival of grandchildren, which helps pass their own genes on.

To him, that’s where reproductive conflict comes in. “You have to not only look at the gains, but the costs you would suffer if you continue to breed.”

The boost in productivity the researchers noticed happened because the music simply made the task less boring and kept the workers alert. This also helps explain later studies finding that music helped surgeons perform better.

When silence and music were put head to head in more cognitively complex tests, people did better in silence.

The more engaging the music is, the worse it is for concentration.

But lyric-free music is less distracting, and some of the people whose performance was improved may have come up with subconscious mental hacks to avoid getting sidetracked by music.

The reason this doesn’t work for most people, Levitin said, is most people can’t pay attention to very much at once. Lyrics can soak up precious attention, as can flashing lights or a really bad smell.

So, I asked Levitin, if listening to music while working is so bad, why do so many of us do it? Simple: We like it, and we can’t tell it’s messing us up.

what Chinese schoolchildren are encouraged to think of as the longstanding natural speech of the common people is in fact an artificial hybrid, only a few decades old, although it shares a name—Mandarin—with the language of administration from imperial times. It’s a designed-by-committee camel of a language that has largely lost track of its past.

The idea of a national Chinese language began with the realization by the accidentally successful revolutionaries of 1911 that retaining control over a country speaking multiple languages and myriad dialects would necessitate reform. Long-term unification and the introduction of mass education would require a common language.

Whatever the province they originated from, the administrators of the now-toppled Great Qing Empire had all learned to communicate with one another in a second common language—Guanhua, China’s equivalent, in practical terms, of medieval Latin

To understand this highly compressed idiom required a considerable knowledge of the Chinese classics. Early Jesuit missionaries had labeled it Mandarin,

The committee decided that the four-tone dialect of the capital would be the base for a new national language but added a fifth tone whose use had lapsed in the north but not in southern dialects. The result was a language that no one actually spoke.

After the Communist victory of 1949, the process began all over again with fresh conferences, leading finally to the decision to use Beijing sounds, northern dialects and modern literature in the vernacular (of which there was very little) as a source of grammar.

This new spoken form is what is now loosely labeled Mandarin, still as alien to most Chinese as all the other Chinese languages.

A Latin alphabet system called Pinyin was introduced to help children learn to pronounce Chinese characters, but today it is usually abandoned after the first few years of elementary school.

The view that Mandarin is too difficult for mere foreigners to learn is essential to Chinese amour propre. But it is belied by the number of foreign high-school students who now learn the language by using Pinyin as a key to pronunciation —and who bask in the admiration they receive as a result.

Since 1949, the Chinese government, obsessed with promoting the image of a nation completely united in its love of the Communist Party, has decided that the Chinese people speak not several different languages but the same one in a variety of dialects. To say otherwise is to suggest, dangerously, that China is not one nation

Yet on Oct. 1, 1949, Mao Zedong announced the founding of the People’s Republic in a Hunan accent so thick that members of his audience subsequently differed about what he had said. He never mastered the Beijing sounds on which Putonghua is based, nor did Sichuanese-speaking Deng Xiaoping or most of his successors.

When Xi Jinping took power in 2012, many online commentators rejoiced. “At last! A Chinese leader who can speak Putonghua!” One leader down, only 400 million more common people to go.

Yet meanings shift.

contributors trace the present meaning of eager, obedient lackey back to at least 1907, when Lloyd George called the House of Lords the Earl of Balfour's poodle

"Das also war des Pudels Kern!" – "So that was the poodle's core!" – which became a German catchphrase

Once you start noticing the metaphors in everything you say, you realise how central they are to human ways of grasping the world

This is why Kerry's armchair works: if you sit down, you are not stepping up to the plate.

This is also the reason why talk of military "strikes" is significant. The term is more metaphorical than it may sound, and calls to mind carefully aimed knock-out punches or lightning bolts. We are more likely to think of a sharp, effective blow than with "bomb", which brings to mind explosions, injuries, mess. Bombs imply a down and outward movement, with things pounded to bits. Strikes imply an into and through movement, which sounds nicer. Our response is physical and instinctive, just as with the up/down distinction.
