You only use 10 percent of your brain. Eating carrots improves your eyesight. Vitamin C cures the common cold. Crime in the United States is at an all-time high. None of those things are true. But the facts don't actually matter: People repeat them so often that you believe them. Welcome to the "illusory truth effect," a glitch in the human psyche that equates repetition with truth. Marketers and politicians are masters of manipulating this particular cognitive bias. "Repetition makes things seem more plausible," says Lynn Hasher, a psychologist at the University of Toronto whose research team first noticed the effect in the 1970s. "And the effect is likely more powerful when people are tired or distracted by other information."

Oral forms like ballads and epics exist in every culture, originating long before the advent of written language. In preliterate eras, tales had to be appealing to the ear and memorable to the mind or else they would simply disappear. After all, most messages we hear are forgotten, or if they're passed on, they're changed beyond recognition - as psychologists' investigations of how rumors evolve have shown. In his classic book Memory in Oral Traditions, cognitive scientist David Rubin notes, "Oral traditions depend on human memory for their preservation. If a tradition is to survive, it must be stored in one person's memory and be passed on to another person who is also capable of storing and retelling it. All this must occur over many generations… Oral traditions must, therefore, have developed forms of organization and strategies to decrease the changes that human memory imposes on the more casual transmission of verbal material." What are these strategies? Tales that last for many generations tend to describe concrete actions rather than abstract concepts. They use powerful visual images. They are sung or chanted. And they employ patterns of sound: alliteration, assonance, repetition and, most of all, rhyme. Such universal characteristics of oral narratives are, in effect, mnemonics - memory aids that people developed over time "to make use of the strengths and avoid the weaknesses of human memory," as Rubin puts it.

Here are the research take-aways: 1. Repetition of tasks - reading, or saying words over and over - continues to be the best method for transforming short-term memories into long-term ones. To do that, we have to retrain our minds to focus on one task at a time. 2. Don't cram. When you rehearse knowledge and practice it often, it sticks, research has shown. So if you can incorporate what you're trying to remember into daily life, ideally over time, your chances of retaining it drastically improve. Space out repetition over the course of days. 3. Sit down and stay put. Memory and focus go hand-in-hand. Dr. Cowan suggests rearranging our office setup to minimize distractions. Stop engaging in useless tasks like surfing the web and just tackle whatever it is you need to work on. Then watch your focus soar and your memory improve. 4. Incentivize moments and read cues. Use visual or verbal cues for items like keys - to associate places and things. Set reminders.

This article looks at Finnish language and talks about how verbal repetition of new words helps with vocabulary development, and can cause the brain to have neural response enhancements. This response also indicated how well they were able to retain the vocabulary. The language background of this study's participants was observed, and they found that those who had learned more languages earlier had greater brain flexibility to acquire new phonology.

Fascinating article on language learning using an app called Memrise. The company's goal: to take all of cognitive science's knowhow about what makes information memorable, and combine it with all the knowhow from social gaming about what makes an activity fun and addictive, and develop a web app that can help anyone memorise anything. Two takeaways for language learning, and acquiring and retaining any subject matter: 1. Elaborative encoding. The more context and meaning you can attach to a piece of information, the likelier it is that you'll be able to fish it out of your memory at some point in the future. And the more effort you put into creating the memory, the more durable it will be. One of the best ways to elaborate a memory is to try visually to imagine it in your mind's eye. If you can link the sound of a word to a picture representing its meaning, it'll be far more memorable than simply learning the word by rote. Create mnemonics for vocabulary. 2. "Spaced repetition". Cognitive scientists have known for more than a century that the best way to secure memories for the long term is to impart them in repeated sessions, distributed across time, with other material interleaved in between. If you want to make information stick, it's best to learn it, go away from it for a while, come back to it later, leave it behind again, and once again return to it - to engage with it deeply across time. Our memories naturally degrade, but each time you return to a memory, you reactivate its neural network and help to lock it in. One study found that students studying foreign language vocabulary can get just as good long-term retention from having learning sessions spaced out every two months as from having twice as many learning sessions spaced every two weeks. To put that another way: you can learn the same material in half the total time if you don't try to cram.

This article examines Nadine Gaab's 2014 study which established a connection - in both children and adults - between learning to play an instrument and improved executive functioning, like problem-solving, switching between tasks and focus. The article also cites the research of neuropsychologist Ani Patel, who advances the OPERA theory of music's benefits for learning. Patel notes "music is not an island in the brain cut off from other things, that there's overlap, that's the 'O' of OPERA, between the networks that process music and the networks that are involved in other day-to-day cognitive functions such as language, memory, attention and so forth," he says. "The 'P' in OPERA is precision. Think about how sensitive we are to the tuning of an instrument, whether the pitch is in key or not, and it can be painful if it's just slightly out of tune." That level of precision in processing music, Patel says, is much higher than the level of precision used in processing speech. This means, he says, that developing our brains' musical networks may very well enhance our ability to process speech. "And the last three components of OPERA, the 'E-R-A,' are emotion, repetition and attention," he says. "These are factors that are known to promote what's called brain plasticity, the changing of the brain's structure as a function of experience."

Information set to music, suggests research, is better retained, as it taps into time- honored strategies that help information stick. Tales that last for many generations tend to describe concrete actions rather than abstract concepts. They use powerful visual images. They are sung or chanted. And they employ patterns of sound: alliteration, assonance, repetition and, most of all, rhyme. A study by Rubin showed that when two words in a ballad are linked by rhyme, contemporary college students remember them better than non-rhyming words. Such universal characteristics of oral narratives are, in effect, mnemonics-memory aids that people developed over time "to make use of the strengths and avoid the weaknesses of human memory," as Rubin puts it. Songs and rhymes can be used to remember all kinds of information. A study just published in the journal Memory and Cognition finds that adults learned a new language more effectively when they sang it.

"...when the exact same material is presented in both media, there is no measurable difference in student performance. ... However, there are some subtle distinctions that favor print, which may matter in the long run. ... First, more repetition was required with computer reading to impart the same information. "Second, the book readers seemed to digest the material more fully. ... seemingly irrelevant factors like remembering whether you read something at the top or the bottom of page - or whether it was on the right or left hand side of a two-page spread or near a graphic - can help cement material in mind. ... spatial context may be particularly important because evolution may have shaped the mind to easily recall location cues so we can find our way around ... E-books, however, provide fewer spatial landmarks than print."

Elise Piazza, lead author and a postdoctoral research associate with the Princeton Neuroscience Institute, said, "Motherese contains exaggerated pitch contours and repetitive rhythms that help babies segment the complex noises around them into building blocks of language." She added that the speaking style also helps parents capture the attention of their babies and engage them emotionally.

Psychology professor Rachel Albert studies babbling, which until recently was considered to be mere motor practice, something babies did to exercise their mouths. Few people thought of it as a vocabulary all its own. But parents, take note: All those repetitive syllables are an important signal. Albert says they tell us that babies are "putting themselves in this optimal state of being ready to learn." Babbles create an opportunity for a social feedback loop - also known as a conversation. And if you listen closely, you can even decipher a babble's four distinctive categories, from the whiny "nasal creaking" of newborns to the more mature bah-bahs and dah-dahs of older babies. But Albert says if you can't tell your "quasi-resonant vocalizations" from your "canonical syllables," don't worry too much. All you really need to know is this: babbling equals learning.

Code-switching involves moving freely between two different languages or dialects of a single language. Many people of color, especially mixed-race and multi-cultural people naturally code-switch. This article shows us Sheena Cobb as an example because she uses both the American Sign Language (ASL) and Black ASL depending on who she is with. Elements of black culture appear in Black ASL such as religious practice, cooking, humor, music, hairstyles, words and phrases typically used in the black communities. People who use Black ASL tend to sign with two hands, in different positions, in a larger signing space and with more repetition than with regular ASL signs.

Skepticism of online "news" serves as a decent filter much of the time, but our innate biases allow it to be bypassed, researchers have found - especially when presented with the right kind of algorithmically selected "meme." At a time when political misinformation is in ready supply, and in demand, "Facebook, Google, and Twitter function as a distribution mechanism, a platform for circulating false information and helping find receptive audiences," said Brendan Nyhan, a professor of government at Dartmouth College (and occasional contributor to The Times's Upshot column). Why? Here are the key reasons: 1. Individual bias/first impressions: subtle individual biases are at least as important as rankings and choice when it comes to spreading bogus news or Russian hoaxes. Merely understanding what a news report or commentary is saying requires a temporary suspension of disbelief. Mentally, the reader must temporarily accept the stated "facts" as possibly true. A cognitive connection is made automatically: Clinton-sex offender, Trump-Nazi, Muslim men-welfare. And refuting those false claims requires a person to first mentally articulate them, reinforcing a subconscious connection that lingers far longer than people presume.Over time, for many people, it is that false initial connection that stays the strongest, not the retractions or corrections. 2. Repetition: Merely seeing a news headline multiple times in a news feed, even if the news is false, makes it seem more credible. 3. People tend to value the information and judgments offered by good friends over all other sources. It's a psychological tendency with significant consequences now that nearly two-thirds of Americans get at least some of their news from social media.

Music is such a powerful tool for children, whether it be singing, playing an instrument, or just grooving along to the beat. There are so many types of songs (repetition, recognition, action, imaginative, etc.) that it reaches out to all types of learners and helps develop their language abilities as well! This article explores how music can really help people with down syndrome!

Jennifer Sclafani, a linguist at Georgetown University, recently wrote a book set to publish this fall titled "Talking Donald Trump: A Sociolinguistic Study of Style, Metadiscourse, and Political Identity." Sclafani notes Trump has used language to "create a brand" as a politician. "President Trump creates a spectacle in the way that he speaks," she said. "So it creates a feeling of strength for the nation, or it creates a sense of determination, a sense that he can get the job done through his use of hyperbole and directness." The features of Trump's speech patterns include a casual tone, a simple vocabulary and grammar, frequent 2 word utterances, repetitions, hyperbole and sudden switches of topics, according to Sclafani. Trump also sets himself apart by the words he doesn't use. For example, he started his sentences with "well" less frequently than other Republican contenders during the 2016 GOP primary debates. Omitting the word "well" at the start of a sentence helped Trump come across as a straight talker who wouldn't try to escape a question asked by a moderator, Sclafani said.

Neuroimaging studies suggest that sign languages are complex linguistic systems processed much like spoken languages, even though they're gestural/visual, not oral. Wernicke's area activates when perceiving sign language; Broca's when producing sign language. In deaf people, lesions in left hemisphere "speech centres" like Broca's and Wernicke's areas produced significantly more sign errors on naming, repetition and sentence-comprehension tasks than signers with damaged right hemispheres.

One of the simplest concepts of sports psychology is developing positive self talk. It's also one of the hardest sports psychology skills to master. Research supports the theory that an athlete who continually practices positive self talk will improve his or her sports performance. Succumbing to negative mental self talk is a sure way to reduce performance and sports success. Over time and with repetition an athlete can develop a new habit of thinking positive statements and thoughts and expect a more positive outcome. It's this connection between the words and the belief that is the ultimate goal of this technique. Another important factor of positive self talk is that it must be possible and believable.
