"An array of electrodes receiving input from a non-tactile information source (a camera, for instance) applies small, controlled, painless currents...to the skin at precise locations according to an encoded pattern. The encoding of the electrical pattern essentially attempts to mimic the input that would normally be received by the non-functioning sense. ... When the encoded pulses are applied to the skin, the skin is actually receiving image data." "After training in laboratory tests, blind subjects were able to perceive visual traits like looming, depth, perspective, size and shape."

There are two hypotheses to why note-taking is beneficial in the first place. The first idea is called the encoding hypothesis, which says that when a person is taking notes, "the processing that occurs" will improve "learning and retention." The second, called the external-storage hypothesis, is that you learn by being able to look back at your notes, or even the notes of other people. A 2014 study published in _Psychological Science_, co-written by Pam A. Mueller of Princeton University and Daniel M. Oppenheimer of the University of California, Los Angeles, suggests that taking longhand notes may have superior external storage as well as superior encoding functions, in comparison to taking notes via laptop.

"Facebook, YouTube and even texting will be the salvation of many of the world's endangered languages, scientists believe. Of the 7,000 or so languages spoken on Earth today, about half are expected to be extinct by the century's end. ... Tuvan, an indigenous tongue spoken by nomadic peoples in Siberia and Mongolia, even has an iPhone app to teach the pronunciation of words to new students. 'It's what I like to call the flipside of globalisation' [said K David Harrison] ... 'Everything that people know about the planet, about plants, animals, about how to live sustainably, the polar ice caps, the different ecosystems that humans have survived in - all this knowledge is encoded in human cultures and languages, whereas only a tiny fraction of it is encoded in the scientific literature.'"

An upcoming and new study shows where language happens in your brain. Scientists have used brain scanning methods to create a virtual "map" showing where words are encoded in our brains.

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.

Examining the results and methodology of a large Whorfian study (17 languages), which tested differences if there are differences in cognition between speakers of verb-frame languages (like Spanish, if the "Path is characteristically represented in the main verb or verb root of a sentence") and satellite-frame languages (like English, if the path is "characteristically represented in the satellite and/or preposition"). Important conclusion regarding study methodology: "Strong claims regarding the (in)validity of the Whorfian hypothesis in the encoding of motion events cannot be made on the basis of a limited number of languages or a restricted range of manner and path contrasts." They could have reached opposite conclusions if they only compared certain language pairs.  This is made in contrast with studies by, e.g., Boroditsky, which had relatively small sample sizes.

Wednesday, November 26, 2014 By Byron Spice / 412-268-9068 PITTSBURGH-Some people say that reading "Harry Potter and the Sorcerer's Stone" taught them the importance of friends, or that easy decisions are seldom right. Carnegie Mellon University scientists used a chapter of that book to learn a different lesson: identifying what different regions of the brain are doing when people read.

Background: Memory is an essential part of our lifestyles that is vaguely understood. Memory is our brain's ability to encode, store, retain, organize, alter, and recover information and past experiences (Klatzky, 1975). It is often divided into three stages known as sensory memory, short-term memory, and long-term memory (Atkinson and Shiffrin, 1971).

Both metaphor and grammar influence how people think about political candidates and elections. voters' attitudes can be influenced by a number of factors, including which information the media chooses to emphasize and how it is slanted. Framing, how a message is worded to encourage particular interpretations and inferences, can influence the perception of political candidates. Negative framing is often used to make opposing candidates seem weak, immoral and incompetent. It is persuasive because it captures attention and creates anxiety about future consequences. Grammar, though seemingly innocuous, also encodes meaning and is linked to mental experience and physical interactions with the world. Information framed with past progressive caused people to reflect more on the action details in a given time period than did information framed with simple past. Using grammatical aspect to frame campaign information, positive or negative, appears to be an effective tool for influencing how people perceive candidates' past actions. It may also be tweaked to invite inferences about what candidates will do in the future because it influences inferences about how events transpire.

Word "edges" are important for language acquisition. Children start to learn the sound of words by remembering the first and last syllables. A new study sheds light on the information the infant brain uses during language acquisition and the format in which it stores words in its memory. Infants start to learn words very early, during the first months of life, and to do so they have to memorise their sounds and associate them with meanings. The study by Silvia Benavides-Varela (now at the IRCCS Fondazione Ospedale San Camillo in Venice, but at SISSA at the time the study was performed) and Jacques Mehler, neuroscientist at SISSA, revealed the format in which infants remember their first words. In particular, the two scientists saw that infants aged about seven months accurately encode the sound and position of the first and last syllable, whereas they have difficulty retaining the order of syllables in the middle.

While this article is directed towards teachers, students can leverage this information to their advantage. Employ the following five strategies to aid retention: 1. Teach a friend. When students explain what they've learned to peers, fading memories are reactivated, strengthened, and consolidated. This strategy not only increases retention but also encourages active learning (Sekeres et al., 2016). 2. The spacing effect: Instead of covering a topic and then moving on, revisit key ideas throughout the school year. Research shows that students perform better academically when given multiple opportunities to review learned material. For example, teachers can quickly incorporate a brief review of what was covered several weeks earlier into ongoing lessons, or use homework to re-expose students to previous concepts (Carpenter et al., 2012; Kang, 2016). 3. Frequent practice tests: Akin to regularly reviewing material, giving frequent practice tests can boost long-term retention and, as a bonus, help protect against stress, which often impairs memory performance. Breaking down one large high-stakes test into smaller tests over several months is an effective approach (Adesope, Trevisan, & Sundararajan, 2017; Butler, 2010; Karpicke, 2016). 4. Interleave concepts: Instead of grouping similar problems together, mix them up. Solving problems involves identifying the correct strategy to use and then executing the strategy. When similar problems are grouped together, students don't have to think about what strategies to use-they automatically apply the same solution over and over. Interleaving forces students to think on their feet, and encodes learning more deeply (Rohrer, 2012; Rohrer, Dedrick, & Stershic, 2015). 5. Combine text with images: It's often easier to remember information that's been presented in different ways, especially if visual aids can help organize information. For example, pairing a list of countries occupied by German forces during World War II wi

Achoo! Atchoum! Hatschi! Etcì! Why does the same body reaction--a sneeze--produce different sounds all over Europe? Different European languages use a different onomatopeia to transcribe into words the simple act of sneezing. And the proper social responses to sneezing in the various countries mean different things and encode varied cultural beliefs about the act.

A 2022 University of Cambridge study conducted by Sahakian, Langley, Chen, et al., and published in the journal _Neurology_, shows that that social isolation is linked to changes in brain structure and cognition - the mental process of acquiring knowledge - it even carries an increased risk of dementia in older adults. Previous research established that brain regions consistently involved in diverse social interactions are strongly linked to networks that support cognition, including the default mode network (which is active when we are not focusing on the outside world), the salience network (which helps us select what we pay attention to), the subcortical network (involved in memory, emotion and motivation) and the central executive network (which enables us to regulate our emotions). This particular study examined how social isolation affects grey matter - brain regions in the outer layer of the brain, consisting of neurons. It investigated data from nearly 500,000 people from the UK Biobank, with a mean age of 57. People were classified as socially isolated if they were living alone, had social contact less than monthly and participated in social activities less than weekly. The study also included neuroimaging (MRI) data from approximately 32,000 people. That data revealed that socially isolated people had poorer cognition, including in memory and reaction time, and lower volume of grey matter in many parts of the brain. These areas included the temporal region (which processes sounds and helps encode memory), the frontal lobe (which is involved in attention, planning and complex cognitive tasks) and the hippocampus - a key area involved in learning and memory, which is typically disrupted early in Alzheimer's disease. We also found a link between the lower grey matter volumes and specific genetic processes that are involved in Alzheimer's disease. Follow-ups with participants 12 years later showed that those who were socially isolated, but not

An important area of the field of second/foreign language teaching and learning is pragmatics -- the appropriate use of language in conducting speech acts such as apologizing, requesting, complimenting, refusing, thanking. Meaning is not just encoded in word semantics alone, but is affected by the situation, the speaker and the listener.A speech act is, according to linguist Kent Bach, "the performance of several acts at once, distinguished by different aspects of the speaker's intention: there is the act of saying something, what one does in saying it, such as requesting or promising, and how one is trying to affect one's audience". Speech acts can be broken down into 3 levels: 1. locutionary: saying something 2. illocutionary: the speaker's intent in performing the act. For example, if the locutionary act in an interaction is the question "Is there any salt?" the implied illocutionary request is "Can someone pass the salt to me?"; 3. In some instances, there's a third perlocutionary level: the act's effect on the feelings, thoughts or actions of either the speaker or the listener, e.g., inspiring, persuading or deterring. The Center for Advanced Research on Language Acquisition (CARLA) at University of Minnesota provides a collection of descriptions of speech acts, as revealed through empirical research. The material is designed to help language teachers and advanced learners to be more aware of the sociocultural use of the language they are teaching or learning. These speech acts include: Apologies Complaints Compliments/Responses Greetings Invitations Refusals Requests Thanks
