Rita Carter -- award-winning science writer, acclaimed author and international speaker -- brings to light this new and vital understanding of personality in THE CROWDED MIND. Rita explains that inside every individual is a team of personalities, working together to give the impression of one unified self. We are used to thinking of ourselves in black and white -- either introvert or extrovert -- but in fact we are all an amalgam of these different characters. That's why we sometimes feel like a different person depending on mood, company and surroundings. In the case of multiple personality disorder, the 'norm' is simply accentuated. This remarkable theory is rooted in the science of psychoneurology -- linking behaviours to physical events in the brain. However, THE CROWDED MIND will also be a practical guide to the maintenance of a happy 'household' of personalities, explaining how and why we need these different versions of ourselves to function successfully in life. A third dimension to this startling book will be its philosophical implications about what it is to be human and truly understand ourselves.
