What I find most interesting about this topic, at least how it relates to me, is that I feel it fantastically coincides with my personality type. I actually scored merely average on that quick test with a 20/40, and to be honest, I wasn't expecting all that high of a number even though I consider myself highly creative and artistic. I've always considered my brand of artistry to relate heavily, ok maybe completely, on emotion. So when painting for example, I always prefer to paint abstract with colors and shapes relative of the emotions I'm feeling at the time.
Relating to this test, I know I can visualize fairly well, but that memory or image that is conjured up, isn't solely a photographic image of something, but also includes how that subject relates to me on an emotional level. When the test asked me to visualize a sunset for example, I was not only imagining the clouds and sun peering through, but the warmth of the sun on my skin with a slight breeze through my hair. I could feel the happiness and sensation of joy I get from seeing a beautiful sunset.
...Shoot, I forget where I was going with...ahh, just read my first sentence. (How does someone literally get mentally sidetracked and start to daydream while typing?!)
Ok! So, back to relating this test to my ENFP personality. Whenever I experience something, I am always keenly aware of all the sensations I am picking up and how the experience is making me feel, and on a deeper level, relating to how it stacks up to a deeply held goal in life in experiencing it to the fullest and enjoying as much of it as I can. So being able to mentally conjure up exact lines and contours of an image is not all I remember of a scene, but merely a part of the equation. I usually envision a general shape of an image with scattered outlines that don't connect but as a whole, make up the image, and then all the emotion, color, smells, and all that other good stuff thrown in.
Sorry that this posting may seem like I'm rambling without any aim, I am seriously going in and out of focus and just inundated with a million other thoughts right now.
