How extreme isolation warps the mind - 0 views

Lara Cowell on 22 May 14This article is relevant to the Genie case, outlining the many ways isolation is physically bad for us. Chronically lonely people have higher blood pressure, are more vulnerable to infection, and are also more likely to develop Alzheimer's disease and dementia. Loneliness also interferes with a whole range of everyday functioning, such as sleep patterns, attention and logical and verbal reasoning. The mechanisms behind these effects are still unclear, though what is known is that social isolation unleashes an extreme immune response - a cascade of stress hormones and inflammation. This response might've been biologically advantageous for our early ancestors, when being isolated from the group carried big physical risks, but for modern humans, the outcome is mostly harmful. A 1957 McGill University study, recreated in 2008 by Professor Ian Robbins, head of trauma psychology at St George's Hospital, Tooting, found that after only a matter of hours, people deprived of perceptual stimulation and meaningful human contact, started to crave stimulation, talking, singing or reciting poetry to themselves to break the monotony. Later, many of them became anxious or highly emotional. Their mental performance suffered too, struggling with arithmetic and word association tests. In addition, subjects started hallucinating. The brain is used to processing large quantities of data, but in the absence of sensory input, Robbins states that "the various nerve systems feeding in to the brain's central processor are still firing off, but in a way that doesn't make sense. So after a while the brain starts to make sense of them, to make them into a pattern." It tries to construct a reality from the scant signals available to it, yet it ends up building a fantasy world.
