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 talks about how the history of social psychology has contributed scientific evidence to help us understand human interactions. Social psychology has been influenced by theorists and researchers throughout history, including Gordon Allport, Kurt Lewin, and Norman Triplett. Research ranges in all types of social settings such as the workplace, educational institutions, society, in the family, etc. It has been found that the way people interact with each other depends on attractiveness, familiarity, associations, perseverance bias, and self-fulfilling prophecies. People belong to various groups whether they choose to or not, and these groups are based on affiliations with others. Group cohesion, connectedness, and belonging are all important things that influence our wellbeing and how we choose to treat others.

This article discusses the impact that social media has on youth. Because most modern teens are learning to do the majority of their communication while looking at a screen, not another person, they are missing out on the extremely critical social skills required for social situations. When you replace face-to-face interactions with screen-to-screen interactions, children do not learn the social cues such as body language, facial expression, and vocal reactions. The article discusses indirect communications, how to lower the risks of your child having bad social skills, how cyberbullying and the imposter syndrome affect teenagers, how stalking other people accounts can lower their self-esteem, and what parents can do to help. Experts worry that because social media and text messages have become so integral to teenage life, they are promoting anxiety and lowering self-esteem.

Is social media good for you, or bad? Well, it's complicated. A UC San Diego study of 12 million Facebook users suggests that using Facebook is associated with living longer -- when it serves to maintain and enhance your real-world social ties. Those on Facebook with highest levels of offline social integration -- as measured by posting more photos, which suggests face-to-face social activity -- have the greatest longevity. Online-only social interactions, like writing wall posts and messages, showed a nonlinear relationship: Moderate levels were associated with the lowest mortality. Facebook users who accepted the most friendships also lived longest.

This article posted by UCSB speaks to the fact that technology is harming our human interaction, and we are reliant on it for many aspects of our everyday lives. The author uses several examples such as texting a friend, emailing a professor (instead of going in for help,) or missing the opportunity to meet new people. It's important to be mindful of how often one is going on a device because there is more to the world than the internet, social media, etc.

This article highlights the importance of social media and how it has the potential to change interactions, dialogue and exchange of new ideas. It specifically goes into detail about how social media is giving voice to thousands of people worldwide who struggle with political oppression. Social media is gaining more popularity and governments are recognizing the its power and responding to the power threat by blocking or banning the use of platforms such as Facebook. Social media is a powerful force that is expanding information across international borders.

Responsive interactions are the key to toddlers' ability to learn language, according to a new study. Researchers studied 36 two-year-olds, who learned new verbs either through training with a live person, live video chat technology such as Skype, or prerecorded video instruction. Children learned new words only when conversing with a person live and in the video chat, both of which involve responsive social interactions, thus highlighting the importance of responsive interactions for language learning.

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.

Social media-from Facebook to Twitter-have made us more densely networked than ever. Yet for all this connectivity, new research suggests that we have never been lonelier (or more narcissistic)-and that this loneliness is making us mentally and physically ill. Social interaction matters. Loneliness and being alone are not the same thing, but both are on the rise. We meet fewer people. We gather less. And when we gather, our bonds are less meaningful and less easy. The decrease in confidants-that is, in quality social connections-has been dramatic over the past 25 years. In one survey, the mean size of networks of personal confidants decreased from 2.94 people in 1985 to 2.08 in 2004. Similarly, in 1985, only 10 percent of Americans said they had no one with whom to discuss important matters, and 15 percent said they had only one such good friend. By 2004, 25 percent had nobody to talk to, and 20 percent had only one confidant.

The LENA System measures the early language environment of children birth to 48 months. It consists of a compact digital recorder with clothing so a child can wear it comfortably; software that turns the recording into data; and a cloud-based system for managing the data. Feedback from LENA helps parents and caregivers increase the quantity and quality of interactive talk. While words are important, "conversational turns" are even more so - times when an adult says something and the child responds, or vice versa. Turns measure interactions, and according to research, they're a very powerful predictor of brain growth. LENA devices were mentioned in "In the Beginning Was the Word" article from _The Economist_.

Stephen Porges, psychiatry professor and Distinguished University Scientist at Indiana University, where he directs the Trauma Research Center within the Kinsey Institute, speaks about the importance of safety in relationships. Porges' Polyvagal Theory describes how our autonomic nervous system mediates safety, trust, and intimacy through a subsystem he calls the social engagement system. Our brain is constantly detecting through our senses whether we are in a situation that is safe, dangerous, or life threatening. People's autonomic nervous system are designed to perceive threat: a protective, defensive survival mechanism, but a response that can also get us into trouble if we sense that our safety is at risk, causing us to misread the situation. However, humans also have a mammalian mechanism that mediates those gut-level ANS responses. This social engagement system enables us to interpret linguistic, facial, tonal, intonation, and gestural cues, and the intentionality of others. When our body and mind experience safety, our social engagement system enables us to collaborate, listen, empathize, and connect, as well as be creative, innovative, and bold in our thinking and ideas. This has positive benefits for our relationships as well as our lives in general. The takeaways: 1. Safety is paramount in crucial conversations and conflict-resolution. 2. Learning to deploy cues that display love, trust, and engagement in the midst of conflict can help disarm defensive, threat response mechanisms in other people, help restore safety in our social interactions, and reaffirm bonds.

This article discusses the results of many studies on how social networking affects mental health. Over the past 10 years, online social networking has caused profound changes in the way people communicate and interact. Several studies have indicated that the prolonged use of social networking sites (SNS), such as Facebook, may be related to signs and symptoms of depression. Some authors have also indicated that certain SNS activities might be associated with low self-esteem, especially in children and adolescents. This review focuses on the recent findings regarding the suggested connection between SNS and mental health issues such as depressive symptoms, changes in self-esteem, and Internet addiction.

Born between 1995 and 2012, teens are growing up with smartphones, have an Instagram account before they start high school, and do not remember a time before the Internet. There is compelling evidence that the devices we've placed in young people's hands are having profound effects on their lives-and making them seriously unhappy.. Some interesting (and disturbing) findings: 1. A 2017 survey of more than 5,000 American teens found that three out of four owned an iPhone. 2. While teens are physically safer than they've ever been, they're also more isolated and more subject to psychological harm. Rates of teen depression and suicide have skyrocketed since 2011. In addition, the number of teens who get together with their friends nearly every day dropped by more than 40 percent from 2000 to 2015; the decline has been especially steep recently. It's not only a matter of fewer kids partying; fewer kids are spending time simply hanging out. 3. Teens who spend more time than average on screen activities are more likely to be unhappy, and those who spend more time than average on nonscreen activities are more likely to be happy. 4. Girls have also borne the brunt of the rise in depressive symptoms among today's teens. Boys' depressive symptoms increased by 21 percent from 2012 to 2015, while girls' increased by 50 percent-more than twice as much. The rise in suicide, too, is more pronounced among girls. While boys tend to bully one another physically, girls are more likely to do so by undermining a victim's social status or relationships. Social media give middle- and high-school girls a platform to ostracize and exclude other girls 24/7. 5. Sleep deprivation: nearly all teens sleep with their phones in close proximity, and the devices are interfering with sleep: Many teens now sleep less than seven hours most nights. Sleep experts say that teens should get about nine hours of sleep a night; a teen who is getting less than seven hours a night is signific

New research suggests it's how parents talk to their infants, not just how often, that makes a difference for language development. Infants whose mothers had shown "sensitive" responses--verbally replied to or imitated the babies' sounds--showed increased rates of consonant-vowel vocalizations, meaning that their babbling more closely resembled something like real syllables, paving the way for real words. The same babies were also more likely to direct their noises at their mothers, indicating that they were "speaking" to them rather than simply babbling for babbling's sake. "The infants were using vocalizations in a communicative way, in a sense, because they learned they are communicative," study author Julie Gros-Louis, a psychology professor at the University of Iowa, said in a statement. In other words, by acting like they understood what their babies were saying and responding accordingly, the mothers were helping to introduce the concept that voices, more than just instruments for making fun noises, could also be tools for social interaction.

2006 NPR interactive news special on the social underpinnings of language, containing short sound bites with various language researchers. 5 topics are covered: the importance of context in helping deduce meaning, social connections and language, Theory of Mind (how humans observe each other, gauging the effect that words are having on listeners, in order to assess others' beliefs, intentions and desires), and empathy. The video clip of Kanzi, the bonobo ape, cooking hamburgers with his human friends is a classic!

Ubiquitous video technology and social media have given deaf people a new way to communicate. They're using it to transform American Sign Language. For more than a century, the telephone has helped shape how people communicate. But it had a less profound impact on American Sign Language, which relies on both hand movements and facial expressions to convey meaning. Until, that is, phones started to come with video screens. Over the past decade or so, smartphones and social media have allowed ASL users to connect with one another as never before. Face-to-face interaction, once a prerequisite for most sign language conversations, is no longer required. Video has also given users the opportunity to teach more people the language - there are thriving ASL communities on YouTube and TikTok - and the ability to quickly invent and spread new signs, to reflect either the demands of the technology or new ways of thinking.

This article describes the result of an experiment which examined babies' neural responses to social interactions with their parents. They found the amount of brain activity had a positive correlation with their future language development and acquisition at three years old.

Western literature exhibits a gradual progression from narratives that relate actions and events to stories that portray minds in all their meandering, many-layered, self-contradictory complexities. Perhaps people living in medieval societies were less preoccupied with the intricacies of other minds, simply because they didn't have to be. When people's choices were constrained and their actions could be predicted based on their social roles, there was less reason to be attuned to the mental states of others (or one's own, for that matter). The emergence of mind-focused literature may reflect the growing relevance of such attunement, as societies increasingly shed the rigid rules and roles that had imposed order on social interactions. But current psychological research hints at deeper implications. Literature certainly reflects the preoccupations of its time, but there is evidence that it may also reshape the minds of readers in unexpected ways. Stories that vault readers outside of their own lives and into characters' inner experiences may sharpen readers' general abilities to imagine the minds of others. If that's the case, the historical shift in literature from just-the-facts narration to the tracing of mental peregrinations may have had an unintended side effect: helping to train precisely the skills that people needed to function in societies that were becoming more socially complex and ambiguous.

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."
