The anchor or anchoring belong to the techniques of Neurolinguistic Programming (NLP). This involves the conscious association of different stimuli with certain responses. The anchors are a kind of mental program that triggers a mental response to a stimulus. This technique is also used in hypnosis, the stimulus can be very simple, for example a finger snap is enough. Other examples are certain movements, touches, scents, or even entire places that are anchored, linked, for example, with a pleasant feeling.
