“The first corollary establishes that when changing the rules of a task, it is always easier on the subject to change all or none (global mode) than to change some but not others.
The second corollary posits that it is always easier to process all of the salient features or attributes of an object or stimulus (global mode) than only some of the properties.
The third corollary states that it is easier to always inhibit a dominant response (global mode) than to do so only some of the time.
The fourth corollary holds that it is easier to do the same thing with both extremities (mirror movement) (global mode) than to do different movements with each.
Finally, the fifth corollary maintains that thinking of movement in a certain direction activates a prepotent tendency to move one’s body in that direction (global mode) and, therefore, requires inhibition of that tendency to move in the opposite direction “
(“One of the advantages of the All or None Hypothesis is that it helps explain a heterogeneous set of phenomena from diverse domains. With respect to the study of perception, behavior, and cognition, Diamond (2009) has described a set of corollaries derived from this hypothesis that make it possible to verify it in each one of these domains.”)
