Jonah Lehrer has an interesting take on e-readers and the possible neurological influence of developing technologies on how we read:
The second reading pathway – it’s known as the dorsal stream – is turned on whenever we’re forced to pay conscious attention to a sentence, perhaps because of an obscure word, or an awkward subclause, or bad handwriting.
Sooner or later, every medium starts to influence the message. I worry that, before long, we’ll become so used to the mindless clarity of e-ink – to these screens that keep on getting better – that the technology will feedback onto the content, making us less willing to endure harder texts. We’ll forget what it’s like to flex those dorsal muscles, to consciously decipher a literate clause. And that would be a shame, because not every sentence should be easy to read.
