The way many of us, especially young adults, consume digital media, often by multitasking, can impair attention, according to new studies.
Media multitasking, which is engaging in the TV program while texting or using social media, is a common activity among the younger population.

A Daily Deluge Of Junk Information

Some of the effects of media multitasking include reduced attention spans, lapses in attention, and forgetfulness of information due to reduced brain-signal patterns.
The lower sustained attention can also result in people having memory recall issues in the long run, as the everyday behaviour evolves into a steady pattern.

Simultaneous TV, texting and Instagram lead to memory-sapping attention lapses

The bulky, modern human brain evolved hundreds of thousands of years ago and, for the most part, has remained largely unchanged. That is, it is innately tuned to analog information—to focus on the hunt at hand or perhaps the forage for wild plants. Yet we now pummel our ancient thinking organ with a daily deluge of digital information that many scientists believe may have enduring and worrisome effects.

A new study published today in Nature supports the concern. The research suggests that “media multitasking”—or engaging with multiple forms of digital or screen-based media simultaneously, whether they are television, texting or Instagram—may <a dir="ltr" href="https://www.nature.com/articles/s41586-020-2870-z">impair attention in young adults </a>, worsening their ability to later recall specific situations or experiences.
