"Based on the size of Heschl's Gyrus (HG), a brain structure that typically accounts for no more than 0.2 percent of entire brain volume, the researchers found they could predict -- even before exposing study participants to an invented language -- which participants would be more successful in learning 18 words in the "pseudo" language."

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 article by Candice Jalili on Time discusses the body language people tend to have when lying. Everyone can lie, in fact, the average American tells one to two lies each day. It explains how to detect honesty in a conversation, including where their eyes go and how their voice sounds. When someone is lying, they are likely uncomfortable, so they may fidget or have frequent voice cracks. Doctors from the healthcare community provide input on signs people display when lying. The main sections of this article are body cues, facial cues, tone of voice, and content of speech. Body cues include hand movement and itching/fidgeting. Facial cues are eye movement, mouth position, change in complexion, and sweating. The section on tone of voice consists of a high pitched voice and changes in volume while speaking. Lastly, content of speech includes phrases people use, filler words, and slip-ups.

You know when you're searching for a word, or trying to say something more nicely than you actually mean it, or trying to make up your mind after you've already started speaking? Whether you reach for an "um" or an "uh" in those situations might depend on whether you're male or female. Our verbal pauses actually speak volumes: "Like," as eighth-grade English teachers will tell you, makes the speaker sound young or ditzy; "sort of" smacks of uncertainty. But according to the linguist Mark Liberman, who works at the University of Pennsylvania and blogs at Language Log, even a difference as subtle as the one between "um" and "uh" provides clues about the speaker's gender, language skills, and even life experience.

"The more he uses technology, the less he uses Braille ... technology is making the nearly 200-year-old writing system more accessible than ever. She shows off an electronic reader that's about the size of a paperback. Instead of having to lug around massive volumes of printed braille, this reader allows Deden to just sweep her fingers over little plastic nubs that rise and fall with each line of text. ... The federation estimates that today only 1 in 10 blind people can read Braille. That's down dramatically from the early 1900s."

I found this really interesting while researching for my field research project. It talks about how humans have the ability to read words that are spelled incorrectly.

"According to a new study by Stefan Wuchty and Brian Uzzi at Northwestern University, we exchange the highest volume of email with those people we know the least. ... the researchers had access not only to the complete email records of a midsize company-nearly 1.5 million messages sent by 1,052 employees over a six-month time span-but also to a detailed map of social relationships. ... People reply to their close friends, on average, within seven hours of getting the email ... this study is a reminder that even in a world transformed by digital devices, the most important things remain constant. Although we can interact with anyone, we still respond most quickly to our closest friends."

Published by Benjamin Franklin in his newspaper, this list of more than 200 slang terms for drunkenness was probably not compiled by Ben Franklin, as is widely reported on the internet.

"... a group of us have been studying ways to make sense of large amounts of language data generated by people on the ground in Libya. ... You won't be surprised when I tell you what event coincides with the most obvious peak in positive emotion as well as in volume of tweet traffic: Gaddafi's death. Specifically, the vertical dashed black line marks the time when news of Gadaffi's capture and death were first made public."

One thing that can get in the way of your social success is when you have a soft or quiet speaking voice. This article will cover the effects of having a quiet voice, the factors that can cause it, and what you can do if it affects you

In a 2013 study, Karla Klein Murdock, a professor of psychology at Washington and Lee University, researched college-age texters. She found high-volume texters who were most stressed in their relationships were also most likely to admit to experiencing academic burnout and the lowest emotional well-being. Poorer sleep quality also seemed to plague the frequent texters. Why might heavy texting carry such a costly toll on people who are highly stressed in their relationships? A reasonable possibility that Murdock suggests has to do with the behavior and expectations of the heavy texter. Texting creates its own relational vortex. If the texts are flying fast and furious, things can easily get out of hand. Without the in-person cues that you would get if you were having a face-to-face discussion, misunderstandings and hurt feelings can quickly escalate. Texting also carries a cognitive cost, draining your attentional resources. As your inner reserve is worn down, you become exhausted and burned out. The physiological activation involved in texting erodes your sleep, and the stage is set for you to feel emotionally depleted.

The constant crackle when you go underwater at the beach is actually shrimp communicating through different volume and intensity of clicks and snaps. Very interesting way of language and communication for these invertebrates.

Good find, Kathryn--thanks!

Dr. Michael Rich is the director of the Center on Media and Child Health and the Clinic for Interactive Media and Internet Disorders. Rich notes some major takeaways: 1.Babies' brains are elastic: the first three years of life are critical for both language and overall brain development. Unlike other animals, humans are born with embryonic brains, rendering babies helpless and in need of caregivers while also providing a developmental advantage: allowing us to build our brains in response to the challenges and stimuli of the environment we're in," In the first three years of life, the brain triples in volume due to synaptic connections, therefore stimuli and challenges babies receive within that time frame help babies build creative, flexible and resilient brains. 2. Face to face interaction is valuable. 3. It's not just about screen time duration, but the type of content being consumed. For example, young children can interact meaningfully via Facetime, if they've previously interacted with that person. However, screens as a distraction for kids in lieu of human interaction= not good.

This article talks about how screen time affects babies language development. The first nine months of a baby's life are important for a child to understand sounds and how they should be used. They are able to understand language much earlier than they actually start talking. Many doctors and scientists encourage parents to communicate with their babies as soon as possible to develop language. Recent studies found that babies that spent more time in front of a screen than talking suffered in language development. I found it interesting that not all screen time is necessarily bad for a child's language development. For example, FaceTime can be beneficially for children because they are interacting in a meaningful way but using screens as a distraction for kids can be harmful.
