New study: multitaskers have lower grey-matter density; link to poor attention, depression, anxiety

New study: multitaskers have lower grey-matter density; link to poor attention, depression, anxiety | 21st Century Literacy and Learning | Scoop.it
A new study reports people who multitask using several media devices at the same time have lower gray matter density in the ACC.

 

The study by Kep Kee Loh and Dr Ryota Kanai found that grey-matter density in the highlighted region of the brain (anterior cingulate cortex) was negatively associated with the amount of media multitasking activity. Credit Kep Kee Loh & Ryota Kanai.

 

Simultaneously using mobile phones, laptops and other media devices could be changing the structure of our brains, according to new University of Sussex research.

A study published today (24 September) reveals that people who frequently use several media devices at the same time have lower grey-matter density in one particular region of the brain compared to those who use just one device occasionally.

The research supports earlier studies showing connections between high media-multitasking activity and poor attention in the face of distractions, along with emotional problems such as depression and anxiety.

But neuroscientists Kep kee Loh and Dr Ryota Kanai point out that their study reveals a link rather than causality and that a long-term study needs to be carried out to understand whether high concurrent media usage leads to changes in the brain structure, or whether those with less-dense grey matter are more attracted to media multitasking.

Les Howard's insight:

Interesting study shows link though not necessarily causality.
