Correlations to CognitiveType
#1) Judgment-Lead / Perception-Lead
"Repeating the question - If I were to just see this activity... (I would say, if I'm sitting there on the computer I'll have some ideas. If I were to get the statistical average that would give me a much better idea) ...would I be able to guess the person's Myers-Briggs type and I would say quite a bit of the time, yeah. Right away there's the sort, is this side [Fp1] or this side [Fp2] more active.That will immediately narrow it down from sixteen to eight." - Dario Nardi
If you look at the graphics, the most consistent differentiation between the sixteen brains per regional average is that all J-leads have red activity in the Fp1 section, while all P-leads have high brain activity in the Fp2 section. The Fp1 region is associated with decision-making, error detection and reasoning. Inversely Fp2 is associated with considering novel information, particularly if unpleasant and taking note of one's placement within a sequence/task. These perfectly coincide with the Jungian Rational/Irrational divide, which is CT's J-vs-P lead divide. Nardi made note that in distinguishing an individual's type via brain pattern the first thing he'd look for is which of these two regions is most active, which aligns perfectly with CT's assertion that the primary axis between individuals is whether they're Judgment-Lead or Perception-Lead.
#2) Te/Fe & Articulation-Leads
CT holds that Te/Fe are articulation processes, and thus are well linked with executive, verbal and decisive brain activity. As seen in Nardi's study, best exemplified by the 4-point-circuit shown in TeNi and FeNi types, these types show high activity in T3, the "Precise Speaker" region. The ability to formulate positions/stances into words was a key component of Je-leads seen by Nardi's trial study, and one also observed by CT visual reading.
#3) Se/Ne & Exploration Process
Additionally, CT holds that both Se and Ne are exploration processes, which are responsible for eye-toggling/darting and aiding in synthesizing information for Pi. CT postulates Se is less scattered, and the eyes dart around less, while still darting, and exploring the environment. This is also perfectly represented by Nardi's study in the way Se is observed in comparison to Ne. Se displays a "tennis hop" like pattern of toggling activity between all regions of the brain, but at a low amplitude, while Ne displays the "christmas tree" pattern that likewise toggles between all regions of the brain, but oscillating between much more varied amplitudes. CT postulates that the eye movements correspond to this scattered brain activity during the engagement of the Exploration processes.
#4) Ni & Hypnotic/Relaxed Process
But more shocking still is the correlation to Ni. CT holds that Ni is a process where the eyes remain steady as the mind holistically recalls its worldview as one interconnected whole. Additionally CT holds that Ni generates a sleepy/hypnotic quality to the eyes during this recollection. This is perfectly exemplified by Nardi's finding that Ni users display a holistic, interconnected Blue-Brain pattern often when presented with novel information. Blue represents low amplitude and a blue-brain pattern is one where the brain is "relaxed, but alert" as well as sometimes "on the verge of sleep", which once again reflects the eye signals postulated by CT theory.
#5) Polar Types
CT theory holds that the primary relation types have to one another is via whether they're J-lead or P-lead, as well as their function oscillation-pairs. By CT's observation, polar types -- taking for example TiNe & FeSi -- are the most similar types to one another because they share J-lead, have the same processes, and in the same hierarchical order, only going in the opposite direction. They're both process information primarily via the decision-oriented oscillation of Ti/Fe, supported and fed by the data of the Ne/Si perception oscillation. Nardi's work also reflected this. In his book he mentions [p:151] that apart from their typical brain pattern, types would have a tendency to temporarily step into the brain pattern of their opposite, or polar, type. The students would not step into another type's pattern, save their polarity.
Trying it Yourself
EEG's can be purchased for below $1,000. Some between $600-$800. This is a more high-tech end, but for those who wanted to identify their type neurologically, you could get at least a rough estimate via comparing one's own activity throughout several hours of doing different tasks, against the averages per brain activity as noted by Dario Nardi.
