The head jitters left to right rapidly while looking forward, as an emphasis of articulation. The head will also drill itself froward slightly in the process.




Rigidity manifests in linear movements of the head, arms and body, as an expression of its linear rationality and decisive convictions. To clarify, previously we mentioned that Horizontal Movements are associated with Fluidity, and while Head Shakes technically exist on the horizontal axis, they do not glide across it.
The head yaws from the tip of the spine, without actually moving or gliding across the horizontal plane itself. As such, during Head Shakes, the person maintains a fixed positional rigidity, emerging from their ideal boundary protection. From this rigid place, Head Shakes function as another avenue of linear-vector expressivity, conveying resolve and finality.
Speculations also exist that Head Shakes may be more innately associated with cognitive rejection or negation[1] or what we may call "negative" judgments, while Head Pushes may indicate more "affirmative" judgments - both of which are essential to the overall role of judgment in distinguishing right from wrong, true from false, or approval from disapproval.
