PR-1 Head Pushes
The person will nod their head and push it forward to emphasize articulation. These head juts may be brief and jittery or long and accentuated. In each case, there is a sharp, angular halt at the end of each head nod, as if sinking a shovel in the ground.

As with Vertical Movements, the up and down strikes of the head are a physical embodiment of the assertion "This is my ground, the exact spot where I stand," effectively "nailing down" their ideas with precise conceptual boundaries. Additionally, the "pushing" of the head forward mirrors their cognitive desire to conceptually "move" the outer world into alignment with their positions and arguments.
