All in the Mind
A stone age brain in a 21st century skull
Anxiety and depression probably fit in a category of what we call technically, genome lag, evolutionary models, which mean that we truly have this Stone Age mind that's not responding well to the modern environment. The rising levels of depression, and very high levels of anxiety, many of us think can be attributed to the fact that our brain is working in normal ways but in, if you like, a very stressful environment, an environment that we did not particularly evolve for. A classic example is panic disorder; it's probably the most common disorder out there after phobias. There's a large number of people out there that have such severe panic symptoms that they don't want to leave their houses. To live in a densely populated city with millions of people is literally terrifying for our reptilian brains and probably our mammalian brains as well. So our brains go into shut down mode, they say get out of there, get back home where it's nice and safe, keep away from all these non-family strangers, they're probably dangerous, they might drag you away to another tribe or worse. There's an example of our biology acting as it should have a couple of hundred thousand years ago perhaps.
You will hear part of a radio programme about psychiatry in which the participants discuss the idea that our brain is still adapted to living in stone age societies. For the following questions, complete the sentences with a word or short phrase.
First, read through the text, then listen to the first part of the programme and complete the gaps. Stop when you get to the end of part one; there is a long silence before part 2.
In the next part of the interview, choose the answer, A, B, C or D which fits best according to what you hear.
