A 24-year-old sufferer of depression was a year ago given a prescription that changed her brain and, therefore, her mindset: a weekly swim in cold water. Sarah, the protagonist of this story, was filmed as part of the BBC documentary series ‘The Doctor Who Gave Up Drugs.’ “It was a series that looked at our … Continue reading A Cold Dip
We blink yet our conscious theatre appears to still hold in mind a holistic and constant image of our surroundings. It follows, then, that the brain must coalesce and retain visual information for short periods of time, allowing the formation of an uninterrupted stream of vision – a useful feature of the human brain. Neuroscientists … Continue reading Why Darkness Doesn’t Descend

For instance, she was once eager to pursue a career as a police officer, only … Continue reading Extraversion is a Risky Business
Studies of intelligence quotient (IQ) differences in a population seem to entail that the variance of intelligence between individuals is predominantly the effect of genetic difference. In fact, genetic variance is said to account for almost 80 per cent of the IQ variances in the population, leaving just 20 per cent of the variance to … Continue reading An Intelligent Paradox Yielding Progress.

This facet of psychological thought is based on the premise that all behaviours are maintained and learnt, or rather conditioned, either through positive or negative reinforcement i.e. an elicited behaviour must be followed by a reward for it to be repeated. B.F. Skinner, … Continue reading Dopamine: A Memoir of Reward, Addiction and Online-shopping.
