Yet another type me plea

I don't have any formal data on the subject.  I only know that I was profoundly depressed during those times, and some of my function scores shifted notably during those times.  Beebe's work on shadow functions implies that we tend to use them more when our 'normal' process isn't working for us as a sort of back up plan.  Depending on how much stress we are under indicates how many function steps we will make in our hierarchy. 

To use myself as an example, under normal circumstances I'm a pretty typical NiFe.  I can get lost in my thoughts for days.  Introduce a little bit of mental challenge and I start to activate my Fe and Se more, seeming FeNi.  Push me into a tense situation and I'll get pensive and in the moment like a TiSe as my Ti amps up and my Se continues to charge.  Put me in an extremely stressful or dangerous situation and my Se takes over, putting me into an SeTi state (which I spent a lot of time in as a child and young adult... long story).  If we get pushed past that limit, we start to go into shadow function use.  In my case, when my SeTi state isn't enough, I get frantic like an NeFi, overwhelmed with possibilities and my deeper emotions.  If I cannot solve the source, I resign to my Fi and the possible bad outcomes like an FiNe, etc.  Eventually, I will become a shell of a SiTe just being a mindless drone at work.

These have all been the case for me depending on where I was on the stress scale. 

Interestingly enough, the neuroscience data does validate this.  We can easily see people of certain types shifting into regions of the brain, and most importantly coherence patterns, that align with various cognitive functions.  For example, a 'stressful' action based video game will pull Ni lead types into a clear Se 'tennis hop' state. 

My theory on this is that the more we are forced to step up our game so to speak, the more experience and development we get with each of those functions and their tandem use with the ones we've already developed.  My cognitive function scores would support this theory, as would the differences in my body language when I'm in those states, and between the times when I hadn't developed their use and when I had.  My early childhood photos are very NiFe, but as I got older the Se started to take over my Fe.

The Doctor, thank you for this analysis and break down of your functions. First, it gives me encouragement, because my assessments were fairly accurate. Secondly, it makes me want to analysis myself and question if I would be able to recognize cognitive functions "unlike" my own in another person, which means that as soon as I have adequate time, I will try. And thirdly, wow, I love the breakdown of the system. I am actually going to use this post as a future frame of reference while I'm learning:)

If I am not mistaken, those are from Nardi's book, which is several years old now.  My maps are compiled from the most recent data.

By the way, in the end you're a NiFe, in your last posts it became pretty obvious actually.
