The eyes and head move in a parallel motion, as if they were a single interdependent unit. If one of the two initiates a transition/drift to another focal point, the other follows it with no delay. The eyes and head, as well as upper torso, retain the same timing/tempo and visual vector.
When the head and eyes move in unison, so too does the person’s psychic attention, which exists in a closely knit relationship to the environment. The eyes have such strong focus and persuasion over the individual that the head and upper torso magnetically follow the steering of the eyes. This signal evidences a psychology that is in a 1:1 contact with reality as informed and governed by sensory perception. For this individual, life unfolds dynamically and fluidly from moment to moment; their attention is directed toward this unbroken real-time flow and to tracking it visually at every passing moment.
To elaborate more fully on this signal, below we have two GIFs showing Se (Paul Rodriguez) and Ne (Kristen Schaal) patterns of head and eye movements. The opaque blue sphere represents the direction of the head, while the somewhat larger translucent circle represents a more general area surrounding the head’s direction. The two red dots represent the direction of the eyes in space.
Notice how for Se-lead Paul Rodriguez, the gaze of the eyes remains within the center of the blue sphere (the direction of the head) while for Ne-lead Kristen Schaal the eyes wander about, leaving the direction of the head and then coming back into it. The eyes of an Se-lead have a more 1:1 relationship between eyes and head. While the eyes may not always stay within the opaque blue circle, they will tend to spend the majority of their time within this blue circle or the wider translucent circle that marks the general direction of the head.
In contrast, for Ne/Si users like Kristen Schaal, the eyes and head vary a bit more independently from one another. They too may coincide with each other, and indeed as P-lead types, Ne-leads will tend to steer their body with their eyes, but the timing will not be 1:1. For example, the eyes of Ne may look to one direction, and immediately the head may start to drift towards that general direction but may take a second or more to get there.
I must differentiate this signal from that of the J/P signals. At a glance it would seem that the Ne/Si pattern of movement better fits with the J-lead “face-centric” signal, wherein the eyes are allowed to move independent of the face. However, this is not exactly the case. The head’s direction in Ne users is still tied to – and magnetically drawn to – the direction of the eyes, but there is a delay in their arrival at the destination. The graphic below demonstrates this:
As we can see, the head of Ne is still directed by the eyes, but there is often a delay at play. The eyes dart about and go out of synch with the head, but the head eventually catches up again. By this we know that the individual is still eye-centric. Both the heads/bodies of Ne and Se are steered by the direction of the eyes, but Se steers the head more immediately. Please do note that this is only a description of extremes, and an effort to paint the most black/white situation. In reality, both Ne and Se eyes may move in unison or with some delay occasionally (such as when Se Toggling), but both will tend to do more of one thing than the other. Furthermore this signal applies mostly to Se-lead types, and Se in a different hierarchy position may not have it quite as strongly.
Further Notes on J-lead
The J “face-centric” signal applies only when the person’s eyes move entirely independent of the head, and the head makes no effort to chase after the eyes neither immediately nor with a delay. If the J-lead is an Se/Ni user, then the head and eyes may move in unison, but the rest of the body (the upper torso) will not move or sway in that direction. Instead, the eyes and head both drift to the sides, then return again to the direction that their entire body is facing — without any torso swaying or ongoing body movements. In this manner, it’s perhaps best to think of “face-centric” as “body-centric.”
Further Notes on P-lead
The P “eye-centric” signal applies only when the eyes and body are both in ongoing movement. If the eyes+head move together but nothing else about the person budges or sways, then this still indicates a J rigid body. Oppositely, if the eyes+head appear to move out of synch (Ne) yet both are drifting about and meeting up with each other at various intersections, then we know this is a P type with Ne/Si eyes.
