In her recently published book ID: The Quest for Identity in the 21st Century, Professor Susan Greenfield brings her considerable expertise as a neuroscientist to bear on the question of whether and how our current use of computers is changing the way our brains work.
Greenfield argues that the visual stimulus we get from screen-based information and entertainment differs so markedly from that available to previous generations that certain areas of the brain, specifically those areas that are older in evolutionary terms and retain the capacity to alter as a result of experience, may be affected in ways that express themselves a changes to personality and behaviour.
It’s an interesting hypothesis, and one that has the virtue of being experimentally testable, unlike many other claims about the effect of modern living on human psychology.
