I’m on my way to the fridge. My intention: to bring out the cheese.  This action is part of a larger contextual frame of “having lunch” which I decided on some minutes ago. Before this, my attention and actions fell within the contextual frame of “working”. To transition from a “work” frame to a “lunch” frame, the sense that it was approaching “lunchtime”, and the sense of my being somewhat hungry, needed to enter my awareness. If all is running smoothly this might feel quite effortless; but it wouldn’t be happening without executive functioning processes running in the background.
