It prompted me to look up some of the research in the area and I found an eye-opening study looking at a range of factors that can effect nerve conduction.
The researchers found that, after controlling for sex, age and temperature (it turns out your nerves are quicker when you’re warm), there was a 0.27 m/s decrease in the conduction speed of one of the leg nerves (the sural nerve) for each additional centimetre in height.
This is interesting because it is not only a reduction in time because the same speed signal is travelling a longer distance, but it actually seems that nerve signals travel more slower through longer nerves as well, owing to the fact the nerves get thinner the longer they are.
The radio segment suggests that taller people don’t experience the world as any different, because our brains try to make everything seem ‘in sync’.
In fact, this is a problem for everyone, no matter how tall we are, because we know we can update our actions quicker than the sensory signals can reach the brain.
In one of the most popular theories that attempt to explain this it it thought that we have an internal simulation of our actions that we can use to make fast decisions which is updated as and when sensory information arrives.
However, I tried to find some studies on whether taller people actually have slower reaction times, but I couldn’t find any, so let me know if you do.
