As the first generation that interacted with digital technology reaches an age where dementia risks emerge, scientists have asked the question: Is there a correlation between digital technology use and an increased risk of dementia? With the phrases “brain rot” and “brain drain” circulating on social media, it would appear that most people would assume the answer is yes. However, a new study in Nature Human Behavior by neuroscientists at Baylor University and the University of Texas at Austin Dell Medical School reveals the opposite – digital technologies are actually associated with reduced cognitive decline.

The study – A meta-analysis of technology use and cognitive aging – was sparked by the ongoing concern about the passive activity of digital technologies and their relation to accelerating risks of dementia. Study co-authors are Jared F. Benge, Ph.D., clinical neuropsychologist and associate professor of neurology at Dell Medical School and UT Health Austin’s Comprehensive Memory Center within the Mulva Clinic for the Neurosciences, and Michael K. Scullin, Ph.D., associate professor of psychology and neuroscience at Baylor.


“You can flip on the news on just about any day and you’ll see people talking about how technologies are harming us,” Scullin said. “People often use the terms ‘brain drain’ and ‘brain rot,’ and now digital dementia is an emerging phrase. As researchers, we wanted to know if this was true.”


The “digital dementia” hypothesis predicts that a lifetime of exposure to digital technology will worsen cognitive abilities. On the contrary, the study’s findings challenge this hypothesis, indicating instead that engagement with digital technology fosters cognitive resilience in these adults. Reviewing more than 136 studies with data that encompassed over 400,000 adults, and longitudinal studies with an average of 6 years of follow-up data, Scullin and Benge found compelling evidence that digital technology use is associated with better cognitive aging outcomes, rather than harm.


The researchers’ study supported the “technological reserve” hypothesis, finding that digital technologies can promote behaviors that preserve cognition. In fact, their study revealed that digital technology use correlates with a 58% lower risk of cognitive impairment. This pattern of cognitive protection persisted when the researchers controlled for socioeconomic status, education, age, gender, baseline cognitive ability, social support, overall health, and engagement with mental activities like reading that might have explained the findings.


Increase in problem-solving skills

Scullin said that for some, these findings are surprising as technology use is often associated with being sedentary both physically and mentally. However, for the current generation of older adults who were introduced to the first technological advancements – computers, the Internet and smartphones – past their childhood, using technology is cognitively challenging because it is everchanging.


“One of the first things that middle-age and older adults were saying is that ‘I’m so frustrated by this computer. This is hard to learn.’ That's actually a reflection of the cognitive challenge, which may be beneficial for the brain even if it doesn’t feel great in the moment.” Scullin said.


Technology requires constant adaption, he said, such as understanding new software updates, troubleshooting Internet loss or filtering out website ads.


“If you’re doing that for years and you’re really engaging with it, even though you might experience frustration, that may be a sign of you exercising your brain,” he said.


Social connection

Technology also enables communication and engagement like never before, which can expand opportunities for connectivity. Video calls, emails and messaging apps help maintain social networks, especially for people who would not otherwise regularly see their family members.


“Now you can connect with families across generations,” Scullin said. “You not only can talk to them, you can see them. You can share pictures. You can exchange emails and it's all within a second or less. So that means there's a greater opportunity for decreasing loneliness.”


Better social connectedness is a well-documented correlate of cognitive functioning in older adults, providing a link between decreased isolation from digital technologies and reduced risks of dementia.


Impact of “digital scaffolding”

A dementia diagnosis is indicated in part when cognitive changes lead to a loss of independence with daily tasks. Tools such as digital reminders, GPS navigation and online banking allow older adults to remain independent despite cognitive difficulties through digital scaffolding.


According to the research article, this digital scaffold “facilitates better functional outcomes in older adults while general cognitive functioning declines.” Technologies can serve as a compensatory support system to maintain general independence and reduce the risk of a dementia diagnosis even with the presence of some cognitive decline.


“As clinical practice continues to move toward an individualized, precision-medicine approach, it will be necessary for the field to identify for whom and for how long, such digital scaffolding is effective,” the researchers said.


Promoting healthy technology use

While Scullin recognizes the negative effects of technology, such as distracted driving or using technology over consistent face-to-face interaction, he also emphasizes how promoting a healthy use of digital tools in older adults is beneficial for their cognitive health.


“If you have a parent or grandparent who’s just staying away from technology, maybe revisit that. Could they learn to use photo, messaging, or calendar apps on a smartphone or tablet? Start simple and be very patient while they learn,” he said.


Social media use is another highly debated topic in terms of cognitive effects. While he says it’s hard to predict the cognitive effects of endlessly scrolling on TikTok, Scullin does argue that generating videos through creative cognition could be beneficial. In addition, he said that interacting with communities online can provide benefits by forming social connections.


“We could spend a long time talking about all the specific ways in which technology use can be bad. However, the net effect since the 1990s has been positive for overall cognition in older adults,” he said.


FUNDING


The study was supported by funding from the National Institutes of Health (R01AG082783; M.K.S., J.F.B.).

The ABCs of Joy: How Adversity, Belonging and Curiosity Lead to a Fuller Life

Young people today have more technology, more convenience and more connectivity than any generation before them. Yet many are struggling with anxiety, loneliness and a growing sense of dissatisfaction in their lives. The problem may be that most people have confused happiness with something deeper, and that’s joy, said Baylor University education researcher Jon Eckert, Ed.D. Data published by the Centers for Disease Control and Prevention shows that approximately one in two 12th-grade girls is not satisfied with herself, and one in three 12th-grade boys is not satisfied with himself. "We are in a happiness crisis. Kids are pursuing what they think is happiness, but they're doing it through ways that don't actually lead to happiness. Joy is different. It's deeper. It's this sense of enduring love and gratitude for others that will emerge through struggle." - Jon Eckert, Ed.D. Through years of research, Eckert identified what he calls the ABCs of Joy – Adversity, Belonging and Curiosity – finding that adversity builds belonging, and belonging cultivates curiosity. These ABCs of Joy, he said, can help people move beyond circumstantial happiness toward a more meaningful and enduring life. “I work with school leaders from all over the world and find that when people believe joy is durable and grounded in lives lived for and with others, those same people often realize the depth of their struggle determines the peak of their joy,” Eckert said. Adversity In a culture that often treats struggle as something to avoid, Eckert argues that adversity is essential to joy. "A lot of times the most joyful people we know have had really hard lives because life can be hard and joyful," Eckert said. "Oftentimes, the depth of our struggle will determine the peak of our joy." Eckert believes that when parents, teachers and coaches remove every obstacle from a young person's path, they may unintentionally prevent them from experiencing the growth that comes from overcoming challenges. "If we rob kids of the chance to struggle, then we also rob them of the chance to experience that kind of joy," Eckert said. “And I'm very clear, it's not trauma that we want for kids; it's adversity. We want them to do hard things and grow from the experience.” Belonging If adversity is where joy begins, belonging is where it grows. Drawing on flourishing research, Eckert said people may succeed independently, but they cannot truly flourish alone. Belonging is rooted in relationships where people know they are valued and supported. “Belonging is the knowledge that we matter to others, and they matter to us, which is knowledge we gain by going through hard things together,” Eckert said. “We may enjoy the fun-loving, carefree friend, but we need the person who shows up when things are hard.” At a time when much of life has moved online, that truth has become increasingly important. Social media and digital platforms offer constant connectivity, but they often fail to provide the deeper relationships people need. The strongest relationships are often forged through shared challenges, and those relationships not only provide support during difficult times, Eckert said, but also create opportunities for joy. Curiosity Eckert believes belonging and curiosity are closely connected. When people feel secure in who they are and in their relationships, they are more willing to engage those whose experiences, beliefs and backgrounds differ from their own. Because of online algorithms and digital echo chambers, many people limit meaningful engagement with people who hold different perspectives and tend to automatically dismiss those who hold ideas or opinions they disagree with. "We've become incurious as a society,” Eckert said. “How do we allow our joy and our love for others to overcome that incuriosity and seek out others? Those are the people that we should want to engage because that's what makes life more interesting." Curiosity is also essential to learning. While grades, degrees and career goals can motivate behavior, genuine learning begins with a desire to know more. "The only real form of intrinsic motivation for learning is curiosity," Eckert said. “Everything else is just delayed gratification.” Joy is more than happiness Eckert challenges the way many people, especially young people, think about happiness. Social media has fundamentally changed the way many young people evaluate their own lives by encouraging constant comparison with curated versions of others’ experiences. "If your happiness is normative and it's compared to other people, you're always going to lose on this," he said. Ultimately, Eckert believes the path forward is not found in comfort or convenience but in embracing the ABCs of Joy. When adversity is met with belonging and curiosity, young people can discover something far more durable than happiness: a joyful life marked by resilience, meaningful relationships and a deeper understanding of themselves and others. "Joy is not freedom from struggle," he said. "Joy is the fuel that allows us to struggle well.” ABOUT JON ECKERT, ED.D.

Go Outside and Play: The Benefits of Outdoor Play for All Ages

The simple act of playing outside offers a multitude of interconnected benefits, profoundly enhancing physical, mental and cognitive well-being. Healthy living expert Renée Umstattd Meyer, Ph.D., professor of public health in Baylor University’s Robbins College of Health and Human Sciences, recommends making outdoor play a regular part of your family’s routine, especially during the summertime when kids are out of school and schedules are typically lighter. “Being outdoors is an equalizer, or at least it can be. Nature offers a lot of opportunities, and there are benefits to all types of being outside, whether it be yards, parks or driveways bordered by trees,” Umstattd Meyer said. “Going outdoors does not require a sign-up fee or certain types of equipment; it is just there waiting for visitors.” Umstattd Meyer’s research focuses on promoting health and access to opportunities for healthy living through an active living lens by collaborating to foster healthy and active opportunities and lifestyles for all people. The benefits of simply being outside, she says, increase through the combination of five factors: movement, connection with nature, connection with others, a reset from busy school schedules and a sense of community. Movement Outdoor play gets kids moving, which inspires creativity, critical thinking and exploration. And research bears that out, Umstattd Meyer said, showing that exercise and physical activity, even in relatively shorter bouts, help with concentration, problem-solving, learning and memory. “Being outdoors beckons us to move our bodies, for kids to run, cartwheel, spin and twirl, play chase, build pill-bug houses, chase lightning bugs, start a pick-up game, and for adults, to walk, exercise, play with our kids, pull a few weeds out of a flower bed, plant and tend to a vegetable, herb or flower garden,” she said. Summertime Safety While playing outside comes with numerous benefits, Umstattd Meyer says a few simple steps will help families safely manage higher temperatures, sun exposure and those pesky mosquitoes: Find time for outdoor play during the cooler times of day. Make sure to have plenty of water and shade available. It's okay to take a break! Use sunscreen and mosquito repellent – reapply as needed. Connection with nature Time outdoors offers well-documented physical and mental benefits, increases awareness and can evoke a sense of environmental stewardship, Umstattd Meyer said. “Just being in nature, whatever the nature might be, from a driveway with a little green around it to local parks, offers those same benefits and connection,” she said. Connection with others Spending time outside also helps people reconnect and step away from the number of devices and screens that contribute to feelings of loneliness and isolation. “Outdoor play also allows opportunities for connection with others, from family members and friends to neighbors,” Umstattd Meyer said. “It provides time and space for adults to connect with others as well, to build relationships, familiarity and trust.” Reset from the schedules Summer play can provide a break from the structured routines of the school year, but Umstattd Meyer said that it requires intentionality. “Taking a break from the planned and orchestrated schedules and demands of the school year and associated stressors, along with a break from screens and devices, will actually foster curiosity and creative thought, opportunities for critical analysis and awareness of caring for our natural surroundings and the environment,” she said. Fosters a sense of community Outdoor play not only benefits children’s health and development, but it also creates natural opportunities for families to build connections and strengthen neighborhood relationships, Umstattd Meyer said. “Being outside with our kids gives us the opportunity to say hello and get to know our neighbors,” she said. “It also allows for parents to become more comfortable with their kids being outside while becoming more acquainted with neighbors, to build confidence that their kids are capable of exploring their surroundings and the outdoors.” Umstattd Meyer encourages everyone to find outdoor spaces and engage in play, which can be planned or spontaneous and is freely chosen at any age. “Play is pursued for enjoyment and recreation rather than serving a serious or practical purpose and enhances health, happiness and quality of life,” Umstattd Meyer said. While technology has improved people’s daily lives, it also has contributed to reduced social connection and engagement with the natural world, she said. At the same time, Americans of all ages are experiencing higher levels of stress and anxiety over demands for higher productivity and achievement. “I encourage each of us to create the time to enjoy nature and plan for ways to regularly engage in outside play in a way that allows you to connect with others and physically move your body,” Umstattd Meyer said. National Play Outside Day The first Saturday of every month marks National Play Outside Day, when people of all ages are encouraged to set their screens and devices aside and head outdoors with friends and families to play together, enjoy nature and discover the multiple benefits of play.

Family Reunion Month: Seven Simple Tips to Begin Recording Your Family’s Oral History featured image

Family Reunion Month: Seven Simple Tips to Begin Recording Your Family’s Oral History

When families gather together for vacations and reunions, they are often regaled with tales about an older relative’s fascinating life story or firsthand experience as an eyewitness to history. So how do you capture and preserve those precious memories? Historians with Baylor University’s renowned Institute for Oral History, home of the national Oral History Association as well as its regional affiliate Texas Oral History Association, have recorded and preserved oral history memoirs of individuals since 1970. Stephen Sloan and Adrienne Cain Darough Stephen Sloan, Ph.D., IOH director, professor of history and executive director of the national OHA, and Adrienne Cain Darough, M.L.S., assistant director and clinical associate professor, share seven simple best practices to help family members begin oral history conversations that enrich recollections of the past. Seven best practices for family oral history conversations 1. Make sure your family member wants their story to be documented or recorded. That's a very important question to ask ahead of time, Cain said. “Many oral historians have run into the spot where, ‘Oh, my grandpa would be great,’ and you get there and it's like, ‘Grandpa does not want to talk to you.’ So first making sure that they want their story recorded.” 2. Determine the type of recording equipment you want to use. Decide if you want to record your interview with an audio recorder or using a video recording device. The Institute for Oral History offers a helpful resource on choosing the right digital recorder for your needs and comfort level. 3. Do some advance research about your family member’s life and their timeline to help you formulate your questions. You can't just put down a recorder in front of someone and say, "Talk." Are there specific things that you want to know? For example, would your family member recall a specific time in their life or a moment in history that affected them? What were they like in high school and what were things they enjoyed doing? Did they serve in the military? “Doing your research to try to form those questions will help you get around what I will say is the reluctance to talk sometimes,” Cain said. “The favorite thing that I love to hear is, ‘Oh, I don't have much to say,’ or ‘I'm not that important.’ And then you sit down with them, and you listen to their stories, and your mind is just blown by the things that they've seen and experienced.” 4. Ask open-ended questions without making any assumptions. With oral history, Sloan said it’s important not to go into the interview with a specific agenda and try to lead anyone to a certain conclusion. “We can do this very subtly by assuming information, but I can't assume that their experience with that topic is X. That could have been very far from how they encountered whatever event that may have been,” Sloan said. “I've got to allow them to relate to me the ways in which they lived these experiences.” 5. Start with the basics, such as “Where are you from?” When Sloan, Cain and their oral history colleagues conduct an interview on any given topic, they generally begin with some life history of the subject, providing important context for historians. “Ask questions early on that are easy for them to answer: a little bit of the backstory, a little bit of where they're from, where they grew up,” Sloan said. “I want to understand the lens through which they experienced events, and the only way I can do that is, who was this? What was formative in their life growing up? Who spoke into who they were? What did they learn? Where did they go? What did they do? Those are the sorts of things that I would be exploring early in the interview.” One of the questions Cain enjoys asking is, “What did you want to be when you grew up?” There is the standard answer, but she notes that there’s often something that happened that may have changed that trajectory. “You want to give them something that's very easy and comfortable to talk about,” Cain said. “What was your favorite subject, just to see if that was something that continued on in their life. If there's a certain hobby or something that you know they're affiliated with, when did you learn about that? Tell me more. What's your interest in this? And then they'll get to talking.” 6. Make sure you are listening, an important facet of gathering oral history. When conducting an oral history interview, you are not only listening for what they're saying, you're also listening for what they're not saying, Cain said. “Are there things that are being skipped around?” Cain said. “For example, sometimes when you're talking to veterans about their combat experience, they need time. There may be some things they have seen and that may be the first time they're reliving or retelling these stories. And you just have to be prepared for that.” 7. Be patient. It might take your subject some time to warm up to the conversation. Patience is a virtue in oral history interviewing. “If you're talking to someone who is 80, 90 or even 100, that's a lot of memories that they have to go through, so patience is important,” Cain said.
