This use of spatial concordance can also be used to show the connection with the moment. If an event takes place in the distant future, the same change in the signature used to point to distant objects can be used to display the chronilogic distance. For example, the “will” sign can be signed slowly and with a jumping movement when the hand is bent forward and the head is slightly blinking backwards with the eyes. This sign can be interpreted in English as “at a given time” or “at a given time”. If an event has just occurred in the recent past, the behavior of the cheeks on the shoulder can be used with the sign “recently” to show that something has just happened. The notion of signifier perspective means that spatial relationships are always signed from the point of view of the signatory in ASL, not adapted to the recipient`s perspective. For example, if you sign on a map, you point to different points on the map as if the card were in front of you. They would not try to return it to confront the recipient. In the same way, with regard to the principle of reality, if you described a room, you would sign it from your point of view, as if you were entering the door of the room with the room on the other side of the door of you. You are not trying to turn the coin in the signature room in front of you to move the door in front of the recipient. In the study of American Sign Language, the notions of “spatial convergence”, “signatory perspective” and “principle of reality” are much balanced. These three closely related terms all simply refer to the signing and demonstration of places and other physical objects as they are in real life. In other words, if you describe in ASL where the bathroom is, you need to indicate the direction in which the bathroom is actually located, not in the opposite direction.
Conversely, if an object is very close, this is shown in ASL by pointing it as if it were so close that you have to remove your index arm in a chicken position, bend your elbow and wrist, point at an angle down and forward. While you are showing this, one can use a non-manual or natural behavior, also called proximity and called cheek against shoulder, by lifting the shoulder of your index finger arm and wearing your cheek near your shoulder by grinding your teeth.
