ninchen thinks like a typical child. She comes out and marvels over and gets excited over things like ladybugs, wonders how they see they world, etc. She lacks the perspective of an adult - the world still revolves around her. She likes creating/building things.
Sonja is the eternal optimist. For the negative/painful/etc, she blocks it out, suppresses/denies/forgets/detaches from it, finds the silver lining, etc. She can tell you why poo is great, lol. She is very talented at knowing how others want her to be/how to respond
niva is fast/frantic in her thinking; very intense. Like strobe lights. She will jump from one thought to the next, and each will be as intense as the last. Short attention span. Dwells on things in a close-minded fashion; is very rigid in her thinking. Judges immediately; attacks us, especially jane. She depersonalizes/derealizes under extreme stress. Makes decisions without thinking them through.
Jane thinks in very slow motion; she is delayed in responding because it takes her a while to comprehend what's been said, and then a while longer to decide how to respond/if to bother responding. Her world is dark, cold - the opposite of Sonja's. She can't see the good in anything, has anhedonia, hates herself for it. She twists everything into her being bad (i.e. why bad things happen to her). She believes herself to be toxic/contagious. She is the most prone to derealization, depersonalization, somatoform dissociation - will lose her ability to see, hear, move, speak, and/or think (freeze response); she can 'disappear'. Doesn't trust her mind/thoughts/judgement on anything, except that which confirms her beliefs.
Aiden obsesses, ruminates, gets completely absorbed. He got us great marks in school

. He can maintain his focus for so many hours; it's hard to pull him away from whatever he's researching for basic things like eating and sleeping and moving. He wants to know the bigger picture, the other side of the story, the details; he wants proof; he wants to know why. He can lose the big picture by being sucked into whatever he's obsessing about. Like niva, he is very stubborn. He loves #s.
We are almost always co-conscious, so my thinking is influenced by whoever is closest (which gets interesting when Sonja and Jane both have a strong presence at the same time! Or niva and jane, etc.) I try to be as non-judgemental and open-minded as possible. I challenge the others when they lack perspective. I like being proved wrong. I love learning in all areas (not just intellectual/cognitive/etc things like Aiden). I am learning how to help us all.
