Developmentally, teens are at particular risk for reckless online behavior, including secrecy regarding social networking. Many people - adults and kids alike - view likes, loves, comments and followers as a barometer for popularity, even within a smaller, closed group. Teens can quickly get caught up in the feedback loop, posting and sharing images and videos that they believe will gain the largest reaction. Over time, teens' own values may become convoluted within an online world of instantaneous feedback, and their behavior online can become based on their "all about the likes" values rather than their real-life values. There is a very real biological basis for this behavior. The combination of social media pressure and an underdeveloped prefrontal cortex, the region of the brain that helps us rationalize decisions, control impulsivity and make judgments, can contribute to offensive online posts. In a recent study, researchers at the University of California, Los Angeles, found that the areas of teens' brains focused on reward processing and social cognition are similarly activated when they think about money and sex - and when they view a photo receiving lots of likes on social media. When teens viewed photos deemed risky, researchers found the brain regions focused on cognitive control were not activated as much, suggesting that it could be harder for them to make good decisions when viewing images or videos that are graphic in nature.

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

Why does psychotherapy favorably compare to medication in treating depression? One reason may be rooted in the evolutionary origins of depression. Scholars suggest humans may become depressed to help us focus attention on a problem that might cause someone to fall out of step with family, friends, clan or the larger society-an outcast status that, especially in Paleolithic times, would have meant an all-but-certain tragic fate. Depression, by this account, came about as a mood state to make us think long and hard about behaviors that may have caused us to become despondent because some issue in our lives is socially problematic. Steven D. Hollon, a professor of psychology at Vanderbilt University, explores the implications of helping a patient come to grips with the underlying causes of a depression-which is the goal of CBT (cognitive behavioral therapy), and is also in line with an evolutionary explanation. The anodyne effects of an antidepressant, by contrast, may divert a patient from engaging in the reflective process for which depression evolved-a reason perhaps that psychotherapy appears to produce a more enduring effect than antidepressants. Hollon notes that depression has a purpose--it spurs rumination about complex social problems, and that CBT can expedite rumination and make it more effective. He states, "For most people, depression motivates them to think more deliberately about the causes of their problems and the solutions they can apply. In most instances in our ancestral past this worked well enough; most depressions remit spontaneously even in the absence of treatment. Cognitive therapy, at the least, hurries the process along and, at the most, helps unstick that subset of individuals who get stuck making negative ascriptions about themselves, typically about personal competence or lovability."

The brains of adolescents are notoriously more receptive to short-term rewards and peer approval, which can lead to risky behavior. But researchers and educators are noticing that young people are also more sensitive to notions of social justice and autonomy. Teenage rebellion can be virtuous - even wholesome - depending on the situation. A new study in the Proceedings of the National Academy of Sciences finds that teenagers make wiser choices if they are encouraged to reimagine healthy behavior as an act of defiance.

Reinforcing good behavior while discouraging disobedience and anti-social behavior generally produces positive results in children. Positive reinforcement helps children feel good about their choices, which motivates them to increase the behaviors that bring rewards. Praise and positive reinforcement usually produces both short-term and long-term positive results. This article talks about how positive reinforcement and encouragement from a young age affects the development of the character of a child.

Robert Provine, a neuroscientist and professor of psychology at the University of Maryland, examines laughter as a means of exploring mechanisms and evolution of vocal production, perception and social behavior. He examines laugh structure, compares human to chimp laughter, sociolinguistic contexts of laughter, the contagiousness of laughter, and pinpoints directions for future study. This article, originally printed in American Scientist 84. 1 (Jan-Feb, 1996): 38-47, is a more in-depth, scholarly article than the other, related article on laughter that I posted: Provine's "The Science of Laughter."

This article talked about how adults talk to babies and why we do it. When we talk to babies, we tend to raise our pitch a little and supposedly, it calms the baby down. They also talked about a research project where they recorded adults from different parts of the world, and noticed that those who come from western places raised their pitch the most, and in remote places didn't raise their pitch that much but everyone raised their pitch at least a little. The way we talk to babies is universal and we've evolved as humans to be able to communicate with infants.

The features of baby talk - softer tone, higher pitch, almost unintelligible vocabulary - are global. Researchers at Harvard's Music Lab documented over 1,500 recordings in 21 urban, rural and Indigenous communities - making their work possibly a first of its kind experiment. The article includes samples from different languages around the world. There are many reasons why baby talk might have evolved in humans and why it might serve beneficial purposes. Some theories suggest that the way we speak accentuates the vowels of the speech and helps babies learn speech. Other theories suggest that this kind of baby talk helps regulate the baby's emotions and helps structure the social interactions we have with babies, so it helps socialize them and control their behavior and mood. In prehistoric times, having ways to interact with babies and to care for them while still being able to keep your eyes up to look out for predators and use your voice to interact with babies, might have been an important reason why we may have evolved these kinds of behaviors.

For teenagers these days, social media is real life, with its own arcane rules and etiquette. Writer Mary H. K. Choi embedded with five high schoolers to chronicle their digital experiences. (This article is an example of qualitative research: data is triangulated and comes from various sources (self-report, actual online behaviors, digital posts).

Recent research suggests older generations are actually more avid users of social networks than their younger counterparts, and that parents are more likely to be active on such networks than non-parents. There is evidence that these digital experiences can have negative effects. Frequent social media use is also a risk factor-one of many, of course-for depression. Sarah Coyne, a psychologist at Brigham Young University, found that new mothers often compared themselves with other mothers on social media, and that this behavior was in turn associated with "higher levels of maternal depression." Annual surveys conducted by The Center for the Digital Future at USC Annenberg show that, since 2012, people feel increasingly ignored by others in their own family households because of smartphone use.

This article addresses the fact that social media could be making us unsocial. The author, Brian Harke, uses an example of a student who attended a professor's dinner party but was so engrossed in his cell phone, he wasn't even aware that his behavior was rude. At the end of the article, Harke provides readers with 13 pieces of advice about how to utilize technology in a way that will help you to be present.

A 2018 study by Vessisiere and Stendel of McGill University in Canada argue that smartphone technology may not be inherently addictive, per se. While many might think that compulsively checking one's phone is antisocial, these researchers claim the behavior is not so much antisocial as fundamentally social: mobile technology addiction is driven by the human urge to connect with people, and the related necessity to be seen, heard, thought about, guided, and monitored by others, that reaches deep in humans' social brains and far in our evolutionary past.

Gratitude is a common aspect of social interaction, yet relatively little is known about the neural bases of gratitude expression, nor how gratitude expression may lead to longer-term effects on brain activity. This Indiana University study tested whether gratitude letter-writing had benefits on the emotional health of depressed patients. Researchers found that a simple gratitude writing intervention was associated with significantly greater and lasting neural sensitivity to gratitude - subjects who participated in gratitude letter writing showed both behavioral increases in gratitude and significantly greater neural modulation by gratitude in the medial prefrontal cortex three months later.

Adopting the same gestures, posture or tone can enhance bonding and help with networking or negotiating. mirroring can help you create powerful connections with others. This behavior, often called "the chameleon effect," often causes others to like and trust you more. Professional networkers, negotiators and salespeople say they use mirroring to help them engage more deeply in a conversation and understand the person they're talking with. Retail salespeople who were told to mimic the nonverbal and verbal behavior of customers sold more products and left customers with a more positive opinion of the store, according to a 2011 study of 129 customers by French researchers. In another study, published in 2008 in the Journal of Experimental Social Psychology, 62 students were assigned to negotiate with other students. Those who mirrored others' posture and speech reached a settlement 67% of the time, while those who didn't reached a settlement 12.5% of the time.

Pew Researchers surveyed more than 1,500 technologists and scholars about the forces shaping the way people interact with one another online. They asked: "In the next decade, will public discourse online become more or less shaped by bad actors, harassment, trolls, and an overall tone of griping, distrust, and disgust?" The vast majority of techonolgists surveyed-81 percent of them-said they expect the tone of online discourse will either stay the same or get worse in the next decade. "Cyberattacks, doxing, and trolling will continue, while social platforms, security experts, ethicists, and others will wrangle over the best ways to balance security and privacy, freedom of speech, and user protections. A great deal of this will happen in public view," Susan Etlinger, a technology industry analyst, told Pew. "The more worrisome possibility is that privacy and safety advocates, in an effort to create a more safe and equal internet, will push bad actors into more-hidden channels such as Tor." Tor is software that enables people to browse and communicate online anonymously-so it's used by people who want to cover their tracks from government surveillance, those who want to access the dark web, trolls, whistleblowers, and others. The uncomfortable truth is that humans like trolling. It's easy for people to stay anonymous while they harass, pester, and bully other people online-and it's hard for platforms to design systems to stop them. Hard for two reasons: One, because of the "ever-expanding scale of internet discourse and its accelerating complexity," as Pew puts it. And, two, because technology companies seem to have little incentive to solve this problem for people. "Very often, hate, anxiety, and anger drive participation with the platform," said Frank Pasquale, a law professor at the University of Maryland, in the report. "Whatever behavior increases ad revenue will not only be permitted, but encouraged."

Kaitlyn Tiffany, the writer of this article from the Atlantic, examines the social media commentary surrounding Russia's invasion of Ukraine. "Milling," a sociological term, refers to the "agitated, aimless buzzing of the type of crowd that gathers in the aftermath of some bewildering catastrophe...We are all just chattering away in restless and confused excitement as we try to figure out how to think about what's happening. We want to understand which outcomes are most likely, and whether we might be obligated to help-by giving money or vowing not to share misinformation or learning the entire history of global conflict so as to avoid saying the wrong thing. We are milling." The word comes from the mid-20th-century American sociologist Herbert Blumer, who was interested in the process by which crowds converge, during moments of uncertainty and restlessness, on common attitudes and actions. As people mill about the public square, those nearby will be drawn into their behavior, Blumer wrote in 1939. "The primary effect of milling is to make the individuals more sensitive and responsive to one another, so that they become increasingly preoccupied with one another and decreasingly responsive to ordinary objects of stimulation." These days, we mill online. For a paper published in 2016, a team of researchers from the University of Washington looked at the spread of rumors and erratic chatter on Twitter about the Boston Marathon bombings in the hours after that event. They described this "milling" as "collective work to make sense of an uncertain space" by interpreting, speculating, theorizing, debating, or challenging presented information.

What does recent research say about the potential benefits of bilingual education? Here are the main 6 findings: 1. Attention: "[Bilinguals] can pay focused attention without being distracted and also improve in the ability to switch from one task to another," says Sorace. Do these same advantages accrue to a child who begins learning a second language in kindergarten instead of as a baby? We don't yet know. Patterns of language learning and language use are complex. But Gigi Luk at Harvard cites at least one brain-imaging study on adolescents that shows similar changes in brain structure when compared with those who are bilingual from birth, even when they didn't begin practicing a second language in earnest before late childhood. 2. Empathy: bilingual children as young as age 3, because they must follow social cues to figure out which language to use with which person and in what setting, have demonstrated a head start on tests of perspective-taking and theory of mind - both of which are fundamental social and emotional skills. 3. Reading (English): students enrolled in dual-language programs outperformed their peers in English-reading skills by a full school year's worth of learning by the end of middle school. 4. School performance and engagement: compared with students in English-only classrooms or in one-way immersion, dual-language students have somewhat higher test scores and also seem to be happier in school. Attendance is better, behavioral problems fewer, parent involvement higher. 5. Diversity and integration: Because dual-language schools are composed of native English speakers deliberately placed together with recent immigrants, they tend to be more ethnically and socioeconomically balanced. And there is some evidence that this helps kids of all backgrounds gain comfort with diversity and different cultures. 6. Protection against cognitive decline and dementia: actively using two languages seems to have a protective effect against age-related demen

Scientists say Koshik, an Asian elephant at a South Korean zoo, can imitate human speech, saying five Korean words readily understood by people who speak the language. The male elephant invented an unusual method of sound production that involves putting his trunk in his mouth and manipulating his vocal tract. Vocal mimicry is not a common behavior of mammals (unless you count humans). Researchers postulate Koshik was apparently so driven to imitate sounds that he invented the method of putting his trunk in his mouth and moving it around. They believe that he may have done this to bond with his trainers, as he was deprived of elephant companionship during a critical period of his childhood and spent years with humans as his only social contact. A video of Koshik with his trainer is embedded in the article.

"...a new study from the University of California, Berkeley, suggests rumor-mongering can have positive outcomes such as helping us police bad behavior, prevent exploitation and lower stress. ... Overall, the findings indicate that people need not feel bad about revealing the vices of others, especially if it helps save someone from exploitation, the researchers said. ... The study focused on "prosocial" gossip that "has the function of warning others about untrustworthy or dishonest people," said Willer, as opposed to the voyeuristic rumor-mongering about the ups and downs of such tabloid celebrities as Kim Kardashian and Charlie Sheen."

Robert Provine, a neuroscientist and professor of psychology at the University of Maryland, summarizes a decade's worth of research in this article. He concludes that laughter is primarily a social vocalization that binds people together. It is a hidden language that we all speak. It is not a learned group reaction but an instinctive behavior programmed by our genes. Laughter bonds us through humor and play. He also explores gender differences in regard to the role of laughter in communication, also laughter as a tool in romance/pair-bonding.
