Wired has an incisive article looking at the science behind the ‘technology and multi-tasking are damaging the brain’ scare stories that regularly make the media.
The piece does a fantastic job of actually looking at specific studies on multi-tasking and distraction and questioning whether the ‘tech scare’ headlines are warranted given the findings.
The conclusion is neither that ‘all is well’ or that ‘we are all doomed’ but that we really have very little data – although none of it so far has given any credence to popular concerns that technology is impairing our intelligence.
The piece also hits on the crucial idea that talking of ‘technology’ or the ‘internet’ as a coherent whole is unhelpful because it has such different forms each with potentially different effects:
A solid consensus on digital multitasking is unlikely to be reached anytime soon, perhaps because the internet and technology are so broadly encompassing, and there are so many different ways we consume media. Psychological studies have seen a mix of results with different types of technology. For example, some data shows that gamers are better at absorbing and reacting to information than nongamers. In contrast, years of evidence suggest that television viewing has a negative impact on teenagers’ ability to concentrate. The question arises whether tech-savvy multitaskers could consume different types of media more than others and/or be affected in diffferent ways.
A research paper authored by a group of cognitive scientists titled “Children, Wired: For Better and for Worse” (pdf) sums it up best:
“One can no more ask, ‘How is technology affecting cognitive development?’ than one can ask, ‘How is food affecting physical development?’” the researchers wrote. “As with food, the effects of technology will depend critically on what type of technology is consumed, how much of it is consumed, and for how long it is consumed.”
There are some quotes from me included, but don’t let that put you off, as it remains a lively discussion of the science behind a common 21st century talking point.
