The movements of the neck, face, and body are linear, angular and precise. The head, arms or body may jitter rather automatically as they speak and communicate their convictions. The body remains in a tense state, from which movements emerge in a vector-like fashion, rather than a fluid or curve-like fashion.
This signal reveals a psychology presently engaged in a very particular elaboration of their thoughts/beliefs. Proper “definitions” are essential to this psychology, and the way their body remains in tension is analogous to the degree of control they exercise over their mind.
