The concepts of anchoring and spatial marking form part of Neuro Linguistic Programming (NLP) and are based on Gregory Benson’s work on contexts and context markers.
Anchoring is applying a gesture, touch, or sound just before a state peaks, either in oneself or someone else, so that the anchored state can be re-activated by reapplying that gesture, touch or sound. A smell can also be used as an anchor. For example, as you remember the smell of a rose, you may find a memory of some experience that involved roses coming to mind.

Spacial Marking is consistently using different areas of space for different actions to associate location with action.
