We have an instinctual part of the brain that reacts to cues in the environment. This happens in 1/60th of a second. In the past it has allowed us to detect danger and evoke a 'fight or flight ' response to a deadly predator lurking in the Forest. In modern day civilisation it can be experienced in as little as a social interaction. In extreme sports, the danger is at the forefront of the sport. White water kayaking involves a descent down a loud, unforgiving, constant flow of water, usually with drops, weirs and sharp rocks. This barricade of sensory overload ann be overwhelming to the primal part of the brain. This is why I am researching how this fear effects performance in white water Kayaking.
