These two projects have been brewing for a long time, and we’re thrilled to finally share them.
Huge thanks to collaborators/friends for their work and patience: Clayton Hickey, Giorgio Coricelli, @eliobalestrieri.bsky.social and Damiano Grignolio.

But how do we keep force stable when feedback is available?
In our EEG study, behavioral performance oscillated at ~6 Hz.
This rhythm was mirrored in the brain, forming a temporal cascade involving Theta, Alpha and Beta frequency bands.

In our behavioral study, participants maintained a steady grip force with or without continuous visual feedback, and with varying incentives.
Without feedback, performance drifted over time.
With feedback, incentives amplified corrections, helping people stay on target.
