Is the ‘net changing our brains…

I’m not sure where to file this one, but Jackie Ashley picked up on a speech in the Lords by neuro-biologist Susan Greenfield. In particular Ashley notes:

The brilliance of Baroness Greenfield’s speech is that she wades straight into the dangers posed by this culture. A recent survey of eight-to 18-year-olds, she says, suggests they are spending 6.5 hours a day using electronic media, and multi-tasking (using different devices in parallel) is rocketing. Could this be having an impact on thinking and learning?

She begins by analysing the process of traditional book-reading, which involves following an author through a series of interconnected steps in a logical fashion. We read other narratives and compare them, and so “build up a conceptual framework that enables us to evaluate further journeys… One might argue that this is the basis of education … It is the building up of a personalised conceptual framework, where we can relate incoming information to what we know already. We can place an isolated fact in a context that gives it significance.” Traditional education, she says, enables us to “turn information into knowledge.”

Put like that, it is obvious where her worries lie. The flickering up and flashing away again of multimedia images do not allow those connections, and therefore the context, to build up. Instant yuk or wow factors take over. Memory, once built up in a verbal and reading culture, matters less when everything can be summoned at the touch of a button (or, soon, with voice recognition, by merely speaking). In a short attention-span world, fed with pictures, the habit of contemplation and the patient acquisition of knowledge are in retreat.
