Sign language is a visual-spatial language. For that reason, sign languages are based on spatial cognitive processes that are not involved in spoken languages.
Deaf people have the ability to generate visual mental images, hold them and rotate them when speaking. In addition, the interlocutors have different visual perspectives of the hands of the person who signs that require a mental transformation for successful communication on spatial scenes.
Therefore, the Deaf have a greater ability to generate relatively complex images and detect mirror image inversions. The image display capabilities of Deaf people who communicate in sign language is outstanding, and this may be linked to specific linguistic requirements of sign languages.
Facial, manual and body place are undoubtedly of vital importance in Writing Signed Languages (W S L), but when it comes to space, we can add that in Writing Signed Languages it is essential, because it is in the spatial place where mainly the hand or hands make the sign.
To understand how this abstract concept of sign language is reflected in its writing, it is enough to observe, understand and the use of the following images.
SPATIAL PLACE -1
Just as there are place alphabetic characters for the face and body, place alphabetic characters in airspace are also used to facilitate writing in sign language.
SPATIAL PLACE -2
The determinative line and spatial locators allow the location of the sign in airspace to be easily described in writing.
To indicate the spatial place where the sign is made, it is enough to familiarize yourself with these 5 alphabetic characters:
These alphabetic characters are easy to remember in their place in space, because to relate them to space, only their orientation changes, as you can see in the previous drawings.
Spatial Place: these spatial place, as you could see in the drawings, indicate the place where the sign is made in space; That is why when a word contains one of these spatial place alphabetic characters within it, it will be understood that the sign begins, ends or is made there.
Its use is easy because it follows the same reading and writing procedure previously explained.
Central Spatial Area: Most of the words in sign language are made directly in the Central Spatial Area in front and in the center of the person who signs, so when writing it will not be necessary to specify it except on necessary occasions; this means that all space cues are placed there. This only changes when followed by a alphabetic character with a different place indicator.
