BBC – Human Instinct 1

This seems to be a 4 part documentary, but I only have parts 1 and 2. This is part 1 and if anyone has part 3 and 4 please seed itThis is very much related to evolutionary psychology, like our natural, instinctual actions to situations.Personally, I find these BBC documentaries very entertaining, especially the main journalist (I forget his name, but he has the sweet mustache)Anyway, this one analyzes our instinctual actions in certain social situations, such as when we are very embarrassed, when we are gambling, when we are trying to read people, etc. Great entertainment while learning. You can even apply it to PU! Read your target hehe, but really there is some great stuff here.Here is the site description:Programme 1 – Born to SurviveEvery one of us possesses an armoury of instincts which keep us alive. We are often barely aware of them, but they act every day to protect us from danger and keep us fit and healthy.Baby at birthBabies alter the pitch and volume of their screams depending on how urgently they need help.In the first programme of the Human Instinct series we explore how this most basic of instincts means we’re all born to survive.A Baby’s CryWithin a few hours of birth, many animals are not only feeding but standing up and walking around. By comparison human babies are virtually useless. So the most important weapon in a baby’s survival armoury is an astounding scream. It can reach 97 decibels – equivalent to a pneumatic drill.Babies alter both the pitch and volume depending on how urgent their need of help. The louder and more piercing the scream the quicker the response. With this simple tactic a human baby ensures it gets all it needs – attention, loving care and of course food.A Question of TasteWithout food we die. But can our instinct to eat explain why we all crave fatty, often unhealthy, food? Like all our instincts, our appetites were formed millions of years ago. In this uncertain world, laying down fat was the perfect way to ensure against times when food was scarce.Robert Winston holding human roundwormRobert Winston inspects a human parasitic roundworm.Our ancestors who craved food which was high in calories and rich in fat lived and passed on their genes to their children – those who didn’t, died and left no descendents. Gradually, over millions of years, that craving for calories became instinctive behaviour.But there’s an even more sophisticated side to our craving for food. We also instinctively know what is safe to eat and what is not.Our tongue has evolved to have 5,000 taste buds – letting us know what to swallow, and what to spit out. And we also have an instinctive reaction to things which could give us a disease or make us sick. At the London School of Hygiene and Tropical Medicine, Dr Valerie Curtis believes our feelings of disgust have helped keep us safe for hundreds of generations.The Feeling of FearEach year at the Pamplona bull run hundreds of people put their survival instincts to the test. Their heart rates soar as they are chased through the streets by angry bulls. They are experiencing fear. This instinctive feeling is so important for our survival, our body reacts before our conscious mind has even registered the danger. Adrenaline floods the body preparing us to fight or run.Bull chasing crowds in Pamplona.The bull run at Pamplona sets pulses racing.A Gambling InstinctIn 1988 North Sea oil worker Andy Mochan found himself in the midst of the furious blaze aboard the Piper Alpha oil rig. Andy defied death by jumping 46m into the crashing waves below. He gambled with his life and won.Millions of years ago our distant ancestors were constantly choosing between risky options, balancing threats from predators and unknown landscapes against potential rewards. We’re all descended from those humans that took risks and won and went on to populate the world. And this most complicated of survival instincts explains why modern humans just love the thrill of gambling.http://www.bbc.co.uk/science/humanbody/tv/humaninstinct/programme1.shtml
