Keeping in touch is no longer about face to face, but instead screen to screen, highlighted by the fact that more than 1 billion people are using Facebook every day. Social media has become second nature -- but what impact is this having on our brain? "In a recent study, researchers at the UCLA brain mapping center used an fMRI scanner to image the brains of 32 teenagers as they used a bespoke social media app resembling Instagram. By watching the activity inside different regions of the brain as the teens used the app, the team found certain regions became activated by "likes", with the brain's reward center becoming especially active." This article goes into depth on how social media like instagram is changing our brain. It shows us what parts of our brain are getting stimulated when we use social media! It also talks about peer influence, social learning, and reward circuitry.

Emotional contagion is the phenomenon of "catching" other people's emotions and moods. According to Elaine Hatfield, a psychology professor at the University of Hawaii, humans are hard-wired "to automatically mimic and synchronize facial expressions, vocalizations, postures, and movements with those of another person and, consequently, to converge emotionally." Primitive emotional contagion is a basic building block of human interaction. It helps us coordinate and synchronize with others, empathize with them, and read their minds-all critical survival skills. When we mimic, the body gets feedback about the expressions we've taken on; we then feel what the other person is feeling. Gary Slutkin, a physician, epidemiologist, and founder and CEO of the nonprofit Cure Violence, says that emotional contagion, specifically anger and violence, springs from four mechanisms involving the brain: 1. Engagement of the cortical pathways for copying, a behavior related to mimicry. The most contagious behaviors are the most emotionally engaging, as well as the ones carried out by the people who are most relevant to you. 2. Activation of the brain's dopamine system, which works in anticipation of a reward. "Activation of that system puts you down a pathway toward what is important socially and for survival," he says. If you anticipate being rewarded for responding to someone with anger or violence, you are more likely to get on that behavioral track. 3. The brain's pain centers activate from veering off or being shut out from getting a reward. "A sense of I can't stand it lights up in the context of disapproval." 4. Serious injuries or abuse cause the limbic system and amygdala in the lower brain to become hyperreactive. "This causes you to be less in control, which accelerates violent behavior," Slutkin says. It also makes you more likely to get angry and be quick to react. "Then there's hostile attribution, another part of what happens with the limbic sy

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

Summary: A new AI-based system called a semantic decoder can translate a person's brain activity -- while listening to a story or silently imagining telling a story -- into a continuous stream of text. Unlike other thought decoding systems in development, this system does not require subjects to have surgical implants, making the process noninvasive.

"Stay Mentally and Socially Active" is an article in the Alzheimer's Association that researches further into the workings of AD and how to mitigate and slow some of the irreversible symptoms that comes with the disease. Through various mental activities and social ones, patients diagnosed with AD can grasp a better understanding of ways to reach out to the community and extend their memories for as long as possible.

A Liverpool University study found reading poetry lights up both the left part of the brain concerned with language, as well as the right hemisphere, an area that relates to autobiographical memory and emotion. Reading triggers "reappraisal mechanisms" that cause people to reflect on their own experiences in light of what they read. The study might also suggest that word choice and sound are crucial elements in creating beneficial literary experiences: more "challenging" prose and poetry (striking wording/phrasing, complex syntax) sparks far more electrical activity in the brain than more pedestrian translations of those passages.

Some adults learn a second language better than others, and their secret may involve the rhythms of activity in their brains. New findings by scientists at the University of Washington demonstrate that a five-minute measurement of resting-state brain activity predicted how quickly adults learned a second language.

This advice is really, really helpful. I agree that it's important to focus on something specific that you're passionate about. At the same time, it's hard to expand on this and be detailed/focused throughout the entire essay. I like the advice of being humble and not showing off because the way you write and your topic can tell a lot about who you are as a person.

I think the best bit of information i took from this article, is showing how the struggle of overcoming some great difficulty. On a general sense, if I were to do an essay on some type of failure, I think the best way to continue the essay would be to show how I was able to push past this downfall, and learn from it. It's important to let the reader understand the hardship you went through and show them how you made the best of a seemingly terrible event.

I think this tip sheet really summed up most of the other articles into a concise, helpful article. Overall, I learned that, in terms of the essay, colleges don't really care about any particular achievements. Instead, the colleges are looking at your voice to see what type of person you are. You should stray from writing about others and focus more about your own feelings and thoughts. Finally, college essay readers have seen all of the generic essays before, so there are more pros than cons in taking a risk by saying something controversial.

"Sustained changes in the region of the brain associated with cognitive function and emotional control were found in young adult men after one week of playing violent video games ... The results showed that after one week of violent game play, the video game group members showed less activation in the left inferior frontal lobe during the emotional Stroop task and less activation in the anterior cingulate cortex during the counting Stroop task."

Actually, there are some studies just about emotional Stroop tests that sound similar to the one in the violent video games study. This looks like a good presentation about how emotional Stroop tests work: http://frank.mtsu.edu/~sschmidt/Cognitive/Emotion1.pdf This one talks about why those Stroop tests work: "In this task, participants name the colors in which words are printed, and the words vary in their relevance to each theme of psychopathology.The authors review research showing that patients are often slower to name the color of a word associated with concerns relevant to their clinical condition." - http://brainimaging.waisman.wisc.edu/~perlman/papers/stickiness/WilliamsEmoStroop1996.pdf This is a meta-analysis of emotional Stroop test studies that describes (actually, it's critical of) how such studies are done: http://www.psych.wustl.edu/coglab/publications/LarsenMercerBalota2006.pdf

Thanks, Ryan! I will take a look at these.

One significant concern that pilots have about cockpit auditory warnings is that the signals presently used lack a sense of priority. The relationship between auditory warning sound parameters and perceived urgency is, therefore, an important topic of enquiry in aviation psychology. The present investigation examined the relationship among subjective assessments of urgency, reaction time, and brainwave activity with three auditory warning signals. Subjects performed a tracking task involving automated and manual conditions, and were presented with auditory warnings having various levels of perceived and situational urgency. Subjective assessments revealed that subjects were able to rank warnings on an urgency scale, but rankings were altered after warnings were mapped to a situational urgency scale. Reaction times differed between automated and manual tracking task conditions, and physiological data showed attentional differences in response to perceived and situational warning urgency levels. This study shows that the use of physiological measures sensitive to attention and arousal, in conjunction with behavioural and subjective measures, may lead to the design of auditory warnings that produce a sense of urgency in an operator that matches the urgency of the situation.

"What you're seeing here is, we've selected the pathways in the brain of a chronic pain patient. This may shock you, but we're literally reading this person's brain in real time. They're watching their own brain activation, and they're controlling the pathway that produces their pain."

"Brain scans of modern stone-tool makers show that key areas in the brain's right hemisphere become more active when they switch from making stone flakes to more advanced tools. Intriguingly, some of these brain regions are involved in language processing... 'Our study reinforces the idea that toolmaking and language evolved together as both required more complex thought.'"

"The researchers can't be sure, but they think the remission of the man's stammer is likely related to his cerebellum damage, which may have had the effect of inhibiting excessive neural activation in that structure."

"An area of the brain called the Visual Word Form Area, or VWFA, is activated whenever it sees something that looks like a word-and is so adept at packaging visual input for the brain's language centers that activation happens within a few tens of milliseconds. ... Instead of being "luminance-defined," words can be "motion-defined," distinguishable from their background not by color or contrast, but by their apparent direction of movement. Against a field of dots moving one way, words made up of dots moving in the other direction will "pop out" to most viewers, even if the word and background dots are the same shade."
