Dimensions of the active-passive distinction discussed in the text (there may be more).

Dimensions of activity-passivity in SGM	Description
Action/movement initiation	Prospective intentions, urge to act, reflective or pre-reflective awareness about what to do next. Preparatory motor potentials, attention to new goals.
Action/movement control	Pre-reflective sense of smooth control or obstacles and breakdowns. Adaptive equilibration via existing or newly learned schemes. Regulation via spinal circuits, etc.
Action/movement monitoring	Attention, whether focused or peripheral, to actions being performed. Ongoing (pre-reflective or reflective) verification of adequacy to intended goals.

Along each dimension different aspects of an action or movement can make it relatively more or less active. SGM, Self-generated movements.
