In a way I've had my own quantum-particles-aren't-solid journey. I started with a desire to make sense of... explain... how movement works, how motor skills in sport are learnt, optimised, performed. I went to the source: the brain. I thought I was smarter than all the other sports people because I was going to become … Continue reading Inseparability

Years ago, I became interested in Parkinson’s disease. I had always been obsessed with sport, but from there emerged a fascination with how improving movement in both athletes and people with Parkinson’s might share the same principles. Kearney & Brittain (2021), Brain Sci. I didn’t set out to investigate this in our paper. Rather, we … Continue reading Sensory Attenuation in Sport and Rehabilitation: Perspective from Research in Parkinson’s Disease
This post was written for STS Community Project. Different ways to control a movement Have you ever seen an athlete choke? The phenomenon of choking in sports is a much studied event, particularly in sport psychology. The idea of an elite athlete failing to perform a movement on a big stage that they must have … Continue reading Coaching with more problem-solving and less instructions, Part 1
We can appreciate a great piece of music without understanding music theory, and can even generate pleasing sounds with various instruments and our voices without understanding music theory or the notes or rhythms we may generate. It's quite incredible really, and I think this example challenges both the theory of the brain and the excessive … Continue reading Why do we ask why?
Just to be a little provocative and take an idea beyond the domain it was birthed and intended for – what happens when a whole day is shaped by predicted sensory consequences and not just a momentary action? In predictive processing, a prediction itself acts as a motor command. This means a context, goal thought, … Continue reading Sensory consequences to bring about actions – where does it end?
I have only just discovered this book (academic PDF link and purchase link), and I have only just read this chapter, but as well as loving reading every page of it, the author Andy Clark provides a really thorough account of predictive processing theory in the context of movement. The topic excites me because it … Continue reading Surfing Uncertainty chapter 4 – Prediction Action Machines
As we interact with the world around us, we process loads of sensory information across different modalities. But this isn't done passively – the overwhelming consensus is that we proactively interact with the environment, using priors or predictions about the world and about sensory consequences to optimise and streamline perception and action. For instance, when … Continue reading Commentary: Forms of prediction in the nervous system – Teufel and Fletcher
I was really impressed by Yaneer Bar-Yam's arguments on how to 'crush the curve' and not just flatten it. He discusses treating communities as infected and not just individuals, as well as how to lockdown effectively, and the flaws of the UK's initial herd immunity approach. His conversation with Azeem Azhar of Exponential View below. … Continue reading Yaneer Bar-Yam discusses response to Covid-19
64 divided by 16 equals 4. That's how division works. But for the sake of a maths puzzle, let's just cross out the digits in the numerator and denominator that are shared by both. In this case, we can cross out both 6's and are left with 4/1 which also equals 4. The question is … Continue reading A small problem
