Are you referring to these?

I think Viktor descriptions are quite good, but they are not perfect. I (and many socionists) claim that +/- is a consequence of the blocking of aspects/functions, so Se+ sees details about subjects: clothes, hairstyle, someone is dancing, someone is flirting etc, and Se- sees details about objects: a nice car, someone is muscular, physical threats, someone is kicking a ball etc. This is the main difference between Se+ and Se-. The difference between 2D and 1D is norm vs. experience.
I think IEI's mental Se+ vs. vital Se- is the most obvious difference. Types with mental Se+ do not talk about the minus aspects of Se, like physical threats.
