I’m interested in the purposeful control of oscillations, such as when we struggle to reliably chunk/load one more item into WM, or when a puzzled dog cocks its head to initiate an AV phase reset.
Among the many hands-on activities to enjoy in Valencia’s spectacular Museum of Science is a pith-ball-moving contest (pictured). Participants don a headset and generate certain oscillations (delta and theta, if I recall) to will the pith ball toward their opponent. Unlike anything you've ever tried.
