Non-matrixed performing = being in performance space doing nothing (doing a certain activity) but being yourself
symbolized matrix = doing something particular, but not in a character
received acting = representing doing something, not actually doing it, or doing it actually but still as part of a performance
simple acting = acting as putting a jacket on, when there’s no jacket
complex acting = adding the weight of a jacket, mood of the character, emotion about the jacket etc to the action
