How the online world is affecting the human brain AskADoctor DailyHealthTips HealthcareMagic
Technology has impacted human activities monumentally. Now, scientists want to know if human brains are being affected too.
Identifying and understanding these changes in children and young adults is particularly important as their brains are still developing. The World Health Organization have already issued concern, recommending that children younger than 5 years old should spend no more than 1 hour in front of a screen on any day.
Multitasking and memory changes Researchers first looked at digital multitasking. Evidence showed that doing multiple things online did not improve people's' ability to multitask elsewhere. In fact, it could make people more likely to pay attention to new distractions. "Given we now have most of the world's factual information literally at our fingertips, this appears to have the potential to begin changing the ways in which we store, and even value, facts and knowledge in society, and in the brain." But, again, further research into the long-term cognitive effects of relying on the internet for facts is required.
Overall, future research needs to focus on young people, as it is somewhat clear that older adults may be positively stimulated by the features the internet offers. We cannot yet make the same conclusions for younger people, however.
