I have a thought:
Se is the one who has a flamboyant intensity. They may or may not use their intensity for making an impact, and they don't always have the same ability to notice vivid details as Si. But as Extraverts, they enjoy breadth of experience, making them good athletes because their inferior Ni function gives them good instincts; knowing which move to make. This trait also guides them to be effective in performing and could give them a vanity streak. Corresponds with Fire.

Si is the one who will appear spaced in, focusing on something in the environment. It is also past, present, and future-oriented. It zeros in on all the details in the environment. You could find Si staring at something that they miss out on the other things that are happening around them. So they, too, have the same problem of Ni of not noticing things beyond their current concentration.
When they are not concentrating on anything in particular, they absorb information that's around them, but unlike Ns, they are not looking for definite opportunities, but merely taking things in. Hence, this type is quite absorbent, able to take in anything from the environment. They are not a store house of just information that interests them or stimulates their mind like Ni, they are a store house of all information. This is why Si's tend to do well in school; they memorize everything in detail that is taught, which does them well when taking tests.
Their past orientation leads them to readily remember all kinds of detailed information based on the matter at hand. Their present orientation allows them an uncanny ability to notice details in the here-and-now. And with an inferior Ne function, they notice what needs to be fixed -- hence, this quality gives them good spatial abilities. And their future orientation allows them to be prepared. Corresponds with Earth.

Ne is the idea person. They may notice details in the environment like Si (and they do have an inferior Si function), but usually not to directly improve (fix) what is in the here-and-now, but details in the environments serves as inspiration, making this type adept at noticing long-range opportunities. They often may appear scattered and superficial, but are usually witty and funny. To the Ne, no idea is too ridiculous to entertain.
This type could also be good at telling stories. For this reason, s(he) could also look to the past using his/her inferior Si function to remember details they've witnessed and put their own spin on things. This could make them into successful salesmen or pathological liars. Corresponds with Air.

Ni is the one who will appear spaced out and not focusing on anything in particular. They are either past, present, or future-oriented. They will look to the past not for any concrete matter at hand, but more to muse upon it maybe relive an experience or explore other musings.
I think past-orientation has more to do with Intuition, because Intuition isn't concrete or abstract per se. Ni will look at their past, present, or future from a more mystical point of view.
A past-oriented Ni will remember something funny, and you might find him/her laughing for no apparent reason. A present-oriented Ni will probably be adept at imagining other people's motivations and seeing things from their perspective. A future/fantasy-oriented Ni will probably end up playing their own creative games.
Ni has an underdeveloped Se function, which could make them prone to mindless physical activity and obsessive compulsions. The same inferior Se function also makes them appear to have ritualistic body movements, such as hand-flapping. Underdeveloped Se also gives them poor motor skills. Corresponds with Water.
