Chronic multitaskers have a harder time with everything.
Research on electronic devices at meetings from Stanford from Clifford Nass's Communication Between Humans and Interactive Media Lab clearly indicate that those who engage in media multitasking are unable to ignore irrelevant information and have difficulty identifying which information is important.
Even watching that stream of type crawl across your television screen during the evening news makes you less likely to retain information from either the program or the crawl.

From another source, The Week:
In a recent TED Talk, Nass explains how college students "triple and quadruple-book media." He says, "When they're writing a paper, they're also listening to music, using Facebook, watching YouTube, texting etc."
To see what impact this has on their brains, Nass tasked 262 college students with completing three experiments that examined different aspects of multitasking: Switching quickly from one task to another, filtering out irrelevant information, and using what is called "working memory," an aspect of short-term memory that allows you to hold multiple pieces of information in your mind.
The results? Chronic multitaskers have a harder time with everything: Telling what information is relevant, managing working memory, and ignoring irrelevant information.
