Simultaneous use of different types of media disrupts memory

Scientists from Stanford University (USA) found out that using several types of media simultaneously - so-called "multitasking media": for example, watching TV, sending text messages and scrolling the instagram feed in Instagram - affects how a person will remember this or that information. In other words, it will prevent him or her from concentrating and, in the long run, degrade the memory, causing the memory to fail. The study has been published in the Nature Magazine.

Evolutionary biologists say that the human brain is originally designed so that it can not concentrate on several tasks at once. Nevertheless, we continue to bring a flow of digital information down on it every day, and this, according to experts, can have long and alarming consequences. These include the deterioration of the ability to remember certain events and situations.

American scientists conducted an experiment involving 80 young people aged 18 to 26 years, who were asked to observe objects on the screen and then evaluate them according to several criteria (for example, size and pleasure). After a 10-minute break, they were shown additional objects and asked to note which ones they had already been shown before. During this time, the authors tracked the subjects' reactions by brain activity and eyes.

In addition, all the volunteers filled out questionnaires where they were asked to indicate how much time they spent in social networks, watching TV and reading news, and how often they had to do it simultaneously.

The results showed that the more time people spent in media multitasking, the worse their concentration and episodic memory was: they more often marked new objects as repetitive and vice versa. That is, they easily forgot the images and events they had encountered some time ago.

At the same time, the authors of the research cannot call social networks and other media resources dangerous for memory. It is the amount of simultaneously consumed information.
