How Phone & Devices Hurt Your Memory | Dr. Charan Ranganath

Memory Effects

Charan Ranganath explains that frequent use of devices with constant notifications can impair memory performance. He mentions that heavy media multitaskers, those who frequently switch between devices, show reduced memory retention. This behavior may also be linked to structural changes in the brain 1.

   

Brain Changes

Research indicates that multitasking behaviors can lead to thinning in parts of the brain, including the prefrontal cortex. Charan discusses whether this thinning is a cause or effect of multitasking. He suggests that people with a naturally thinner prefrontal cortex might be more prone to distraction and multitasking 1.
