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

This goes into Chinese "chengyu" or four-character idioms used heavily in mandarin, much like our "two birds, one stone." Like English idioms, origins vary between chengyu, but often they're old stories and have been used for ages in colloquial language.

This article is about a study suggests that bilingualism can possibly decrease chances of getting dementia and cognitive decline in older people. The study was published in the journal Neurobiology of Aging. It hypothesized that because bilingual people can switch between two languages seamlessly, it can be used in multitasking, self-control, emotion management, possibly delaying dementia. However, the study only focused on bilingual people who use two languages everyday for a long time. Because of the different degrees of bilingualism, it's difficult to know if it really can delay dementia.

This article talks about how our brain works while acquiring language and using language. As we grow and out brain grows, different parts of our brain lights up as we age.

The urge to converse with animals is age-old, long predating the time when smartphones became our best friends. A new app, is the product of a growing interest in enlisting additional intelligences - machine-learning algorithms - to decode animal communication. The app detects and analyzes cat utterances in real-time, assigning each one a broadly defined "intent," such as happy, resting, hunting or "mating call." It then displays a conversational, plain English "translation" of whatever intent it detects. MeowTalk uses the sounds it collects to refine its algorithms and improve its performance, the founders said, and pet owners can provide in-the-moment feedback if the app gets it wrong. In 2021, MeowTalk researchers reported that the software could distinguish among nine intents with 90 percent accuracy overall. But the app was better at identifying some than others, not infrequently confusing "happy" and "pain," according to the results. Dogs could soon have their own day. Zoolingua, a start-up based in Arizona, is hoping to create an A.I.-powered dog translator that will analyze canine vocalizations and body language. Still, even sophisticated algorithms may miss critical real-world context and cues, said Alexandra Horowitz, an expert on dog cognition at Barnard College. For instance, much of canine behavior is driven by scent. "How is that going to be translated, when we don't know the extent of it ourselves?" Dr. Horowitz said in an email.

Outlines the importance of early children's language development. It highlights the importance of the four main components to early language development: Phonology, Semantics, Grammar and Pragmatics. This article shows the critical period of first 5 years in development as this is the time that baby's nerve connections are being made and those for speech/communication need to be built early on so that they're inherent to learning.

This article is about the evolution of language and its correlation to music throughout the ages. Levman goes on to continue to explore the definition of music, and how to distinguish music and language

This article features an interview with linguist Gretchen McCulloch about how the Internet has changed our language. McCulloch provides insight that disputes the idea that the Internet is killing or destroying our language. The article covers topics such as language usage amongst different age groups, emojis, the use of punctuation and capitalization, text speak, and more.

This was an interesting article I used for my Smorgasboard project. I wanted to study how dementia affects our ability to speak and understand language. This article covered different types of aphasia, or loss of language that occur when one has either Alzheimer's or other types of dementia.

This article talks about general language disorders, how to detect impairments, options for treatment, and much more. More specifically, one portion of the article focuses on receptive versus expressive forms of language, and the characteristics that fall beneath each of these categories. Lastly, the article addresses how parents can help their child succeed from a young age.

The culture of Okinawa, Japan is quite distinct from other Japanese islands. It became a part of Japan in 1879, but has a strong American influence because of three decades of military occupation following WWII. Today, 20% of the island is made up of over 30 U.S. military bases. This history has resulted in the near extinction of the Okinawan language, called Uchinaguchi, which was systematically suppressed when the island was annexed by Japan. Because of ubiquitous U.S. presence, Okinawans perceive more of a need for English competence than for learning the language of their ancestors. Once the U.S. ceded control of the island back to Japan in the 1970's, the island underwent changes that many Okinawans perceived as another occupation, but this time instead of U.S. military projects, Japanese business took over the island. Japanese power over Okinawa can even be seen in the language politics: Uchinaguchi was long considered a dialect of Japanese despite the two languages having less than 60% in common. In 2009 UNESCO recognized Okinawan as its own language along with five others spoken in the region, all of which are endangered. Native speakers are aging and dying off. Efforts to revitalize Uchinaguchi on the island are regularly stifled by the local government's indifference towards the language. Nonetheless, the language is praised for its folkloric value and is featured in local theater. Some schools offer language classes, such as Okinawa Christian University. Because Uchinaguchi is a low priority in the political field, the cultural field is the site of language revitalization and resistance to its extinction. One benefit of promoting the language through culture is that, unlike the government, the culture can have influence overseas.

This article talks about the importance of speaking development of babies from ages 0 to 12 months old. It helps parents (and others) understand how a baby tries to communicate their feelings with the noises they make. It is useful to know the way babies try to speak to us in order to understand if they are hungry, tired, happy, etc. and be able to respond to their needs.

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 article writes about the variation in speech rate. Some languages tend to have more syllables per a second. For example, French, Japanese, and Spanish speakers tend to have speak more syllables per a second (almost 8/s) than German, Vietnamese, or Mandarin speakers (roughly 5/s). Although stereotypes exist relating to speech rate, there is no connection between intelligence and speech rate. One significant and consistent variable in speech rate is age. Children speak slowly, then speed up until their 40s, then slow down again in their 50s and 60s.

The author of this article discusses the study she conducted that explored how punctuation is used in texts to convey tone. The participants in the study consisted of 122 college-aged students (mostly from Boston College), and they were surveyed to gather data and responses. The discussion of the study shows trends in how text messages are interpreted and how subtle changes in text punctuation can alter the meaning or tone of the message.

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.

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.
