Study: Multimedia Multitasking May Be Shrinking Human Brains

An anonymous reader writes It seems that switching between laptop, smart phone and tablet may be shrinking our brains and leaving us prone to higher levels of anxiety and stress reports new research from the University of Sussex in the UK. The researchers point out that the link is currently a correlation rather than a proof of causation, but they do suggest that people who used a higher number of media devices concurrently also had smaller grey matter density — in other words they have smaller brains.

Density

From the summary: ... had smaller grey matter density — in other words they have smaller brains.

That is NOT what density means. Density is an intrinsic property, and does not in any way imply smaller size.

Also, the correlation between brain size and intelligence is very weak.
