Concept cleaning

I am trying to clean up some of A.s.a. H.'s concepts by manually editing its case base. This isn't easy. The concept "move", as learned by A.s.a., includes the sensation of "sound". A.s.a. has heard its motors/servos running as it moves its body or its manipulators. Should I delete "sound" as a vector component of  "move"? Similarly, should "pain" be a component of "damage" or not? As a compromise I can simply reduce the strength of some vector components but not delete them entirely. But reduce by how much?
