Using smartphones has become such a common "frightening" behavior in daily life. More and more people are attached to a mobile device, whether it's a smartphone, tablet, or even a mobile device. The laptop is showing the success of technology in creating user's living habits. However, on the contrary, it also brings negative effects.
A recent study by Science direct found that up to 89% of college students in the US suffer from "imaginary phone vibration", imagining that their phone is vibrating, but in reality there is no good call. which message. Another study found that up to 86% of Americans have strange habits that make them constantly check email and social media accounts without any notification. This makes them feel really tired.
In an interview with Business Insider, endocrinologist Robert Lustig explained that smartphone notifications are putting people's brains in a state of stress and fear almost all of the time, making it an integral part of the world. indispensable. This causes the cognitive ability of the brain to be disturbed.
The human brain can only do one thing at a time
Normal human brain can't multitask. Normal human brain can't multitask.
Scientists have long made the point that not everyone admits, that humans by nature cannot multitask - just like a smartphone can listen to music, surf the web and run office applications.
This is true for about 97.5% of the population. Meanwhile, the remaining 2.5% are people with strange abilities, which in the language of scientists are "super taskers". These people are really capable of doing multiple tasks at the same time, such as driving while making phone calls, without affecting the ability to control the vehicle.
However, for the average person who makes up 49/50 of the population, we can only really focus on a single action. That means that every time we turn our attention to a notification stream or a tone from the phone, other work will be interrupted, and this payment is called “switching cost”. .
The key point about this interruption is that we don't notice its existence because it usually happens very quickly, with only about 1/10th of a second. However, if the situation is repeated, combined with the messy thought lines between ideas, conversations, ... increasing day by day, it can make the brain vulnerable.
Psychologist David Meyer has studied this effect and estimates that switching between tasks can use up to 40% of the brain's productivity, thereby leaving the brain unable to "spend" on tasks. is different.
The more smartphones are used, the more lazy the brain is to exercise
According to research by scientists, the adult brain has a huge processing speed, equivalent to 60 bits per second. The more tasks we have to do, the more we are left with a choice about how we want to use our brain power.
This also explains the benefits that smartphones or AI bring in sharing less work for users. Besides, we increasingly tend to search for information using smartphones instead of traditional methods.
But according to scientists, this brings unexpected negative effects.
A recent study conducted on dozens of smartphone users in Switzerland found that staring at the screen makes them feel stressed and fingers jittery.
Smartphone use brings many harmful effects, including addiction and depression in both men and women. Smartphone use brings many harmful effects, including addiction and depression in both men. both female.
In research published in March 2018, psychologists and computer scientists discovered an unusual and potentially troublesome connection: That's when we click or Use your finger to tap the screen. Specifically, the more you do these operations, the more confusing the human brain signals become.
According to the explanation, scientists believe that learning knowledge, or specifically social behaviors, requires more resources and a process than just a signal from the finger to the eye to the brain. the set.
This finding surprised even scientists, because logically, the more often we do something, the faster, better, and more efficient we can do it. However, it seems that the more smartphones are used, the more "lazy" the brain becomes.
