"In 1967, Hans Eysenck published his "arousal theory" of introversion and extroversion which predicted that ... introvert brains would be more stimulated on an ongoing basis; ... this would explain why introverts pull away from environmental stimuli while extroverts seek out more."
This explains to me my extreme sensitivity to background noise. I cannot have a conversation while there is background music, either I need to turn the music down enough so I cannot hear it, or I want to listen to the lyrics and I find another person talking to me irritating. I love to have music on in the kitchen, but often find my tension levels rising and have to switch it suddenly off.
My desk has been in a busy part of the house and there are many times I have found myself yelling at the children or the occupants of the next room for disturbing me. Last week, we bought a refurbished lap-top and I have turned my bedside bureau into a desk. It is my space and my lap-top and I am typing this sitting on my bed in the peace and quiet of my own room.
As I get to know myself better and accept who I am, I am finding ways of living that suit me better: embracing my introvert nature, understanding it and allowing myself to be this way.
