Wonderous thought

Do deaf people conceptualise the nature of motion while moving the hands as different forms of symbolic iteration?
As to say, the more flowing the movement, the softer the communication; The stiffer and more rigid the arrangement, the rougher the symbolic expression?

I observe that in people, but for a different reason.
It gives me understanding of their biological integration.
Subtle more flowing body movements usually hints at higher sophistication, as it requires more micromovements – hence integrated consciousness; feeling the muscles. Some people move like they float through space and time.
Other like they are mechanical in their patterns.
