Is technology ruining children?

Technology is moulding a generation of children unable to think for themselves or empathise with others, says the leading brain scientist Susan Greenfield. Is it time to switch off? Susan Greenfield’s theory goes like this. The more we play games, the less time there is for learning specific facts and working out how those facts relate to each other. This can result, she maintains, in a failure to build highly personalised individual conceptual frameworks – the whole point of education and the basis of individual identity. If the purpose of a game, for instance, is to free the princess from the tower, it is the thrill of attaining the goal, the process, that counts. What does not count is the content – the personality of the princess and the narrative as to why and how she is there, as in a storybook. Greenfield avers that emphasis on process in isolation becomes addictive and profoundly mind-changing.Here is her hypothesis. A natural brain chemical called dopamine is involved in all forms of addiction. Dopamine contributes to feelings of wellbeing on attaining a goal, especially when gratification repeatedly deferred is finally delivered. Falling levels of dopamine accompany the opposite situations, when gratification has been frustrated (for example, waiting for a phone call that never comes).
