One thing I think characterizes the thought process is that it spends more time on the stage of "learning to understand" a problem (or subject matter or environment or... etc). Basically it spends a lot of time familiarizing itself with the topic. Once this familiarization stage is completed, it can act very quickly and decisively in that particular environment, but it becomes difficult to attain the same level of control in any new endeavor. Positive/Process types on the other hand sort of "rush" to materialize their understanding, so they reach the point at which they can decide quicker, but they don't ever get to the point where a topic is "familiar" to them. This means that they need to keep making an large effort no matter how familiar they are with the subject in question.
Negative/Result is all about reaching that state of familiarity where a very relaxed kind of control is possible, but one needs to make a big effort to get there.
Negative/Result: slow to understand, very relaxed control once familiar with the topic
Positive/Process: quick to understand, pretty much never reaches state of relaxation and keeps making the maximum effort
