Surfing Uncertainty chapter 4 – Prediction Action Machines

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 …

Thoughts on sensory attenuation, body state estimation and whole vs part practice

During movement, a predictive signal with information on the consequences of an action is integrated with an afferent signal with actual sensory information triggered by the movement. This helps overcome neural delays and navigate noisy environments. Without brain stim, there are probably two main ways to alter the balance of these two signals, the combining …

Pegs.

I collected the data from the first participant for my pegboard task this week. It's a simple pilot study where we aim to investigate how sensory uncertainty affects motor learning during a fine motor control task. The participant simply has to fill holes on a pegboard with pegs, but one group wears a blindfold to …
