By having groups of objects scroll faster and faster, the activity is supposed to improve reaction time. But in a analysis of research on brain-training programs, Simons and his colleagues are far less laudatory. The paper, which includes an in-depth analysis of the ACTIVE study, says that the overall risk of having an accident—the most relevant criterion—decreased very little. Several reviews of the scientific literature come to much the same conclusion: brain-training products enhance performance on tasks that are trained directly, but the transfer is often weak.
In addition to attention and memory exercises, this game has a player do calculations. Does the program improve overall arithmetic skills? A year earlier, though, Scottish psychologists David Miller and Derek Robertson found that the game did increase how fast children could calculate.
Overall then, the results from studies are mixed. The benefits need to be evaluated better, and many questions need answering, such as how long an intervention should last and at what ages might it be effective. The answers may depend on the specific interventions being considered.
Indeed, the measured benefits are much weaker and ephemeral than the benefits obtained through traditional techniques. Unlike brain-training games, this kind of approach involves taking some initiative and makes you think about what you know. Exercising our cognitive capacities is important to combating another modern hazard: the proliferation of fake news on social networks.
In the same way that digital devices accentuate our tendency to become distracted, fake news exploits our natural inclination to believe what suits us. The solution to both challenges is education: more than ever, young people must be taught to develop their concentration, self-control and critical-thinking skills.
John Dunlosky et al. Daniel J. Simons et al. Bediou et al. Already a subscriber? Consider this: Nearly half of all children 8 and under have their own tablet device and spend an average of about 2. Jennifer F. Interacting almost exclusively with screens would be like working out only your arm muscles and nothing else.
You would have really strong arm muscles, but at the expense of overall fitness. Health Matters spoke with Dr. We know that kids have easy access to screens, now more than ever. But how do screens affect early childhood development? For young children, especially those under the age of 3, development is happening rapidly.
Young children learn by exploring their environment and watching the adults in their lives and then imitating them. When I see children walking with a parent or being pushed in a stroller, they are often playing on a smartphone or a tablet and not paying attention to anything else around them. This will not just affect their ability to learn new things, but also how they interact with others and how language develops. Studies have shown that children under 2 learn less from a video than when learning from another person, and it appears that although children will watch the TV screen by 6 months, understanding the content does not generally occur until after age 2.
There is also some evidence that children who watch a lot of television during the early elementary school years perform less well on reading tests and may show deficits in attention. Tell us more about how screen time affects language and communication.
Research shows that talking with children in a reciprocal dialogue is extremely important for language development and social interaction. What age is appropriate to introduce screens? Pediatrician Michael Rich, wants to understand how—and help children and parents manage their online behavior in this ever-changing digital landscape.

Children need a diverse menu of online and offline experiences, including the chance to let their minds wander. The experience of growing up today, as youth move seamlessly between online and offline environments, is the focus of an international research project that Rich is leading. The investigators plan to follow 3, to 5, youths over 10 years, examining the impact of digital technology on their physical, mental, and social well-being.
Because this technology is evolving so rapidly, findings from the Global GUD participatory research will be released in an ongoing way so that health and educational professionals, parents, and youth can implement positive changes in real time. As with most things, it will probably be a mix of positive and negative. Going forward with our eyes open, how can we enhance the positive and mitigate the negative? Children over age 2 should be limited to 1 to 2 hours of screen time per day.
Adults should also try to limit their screen time outside of work hours. Check out our amazing community resources throughout the Valley!
