SRK framework

This is in response to an article on GameCareerGuide.com over here.

The article is on the application of the SRK framework to Game Mechanics. SRK means Skills, Rules, and Knowledge based behaviors.The SRK framework is a method for separating tasks into categories to find any problems within a system of people. Skill-based behaviors are those that are subconscious, such as driving a car, or at a video game level - moving, aiming, selecting etc. Core mechanics are repeated tasks within a game that should not require any thought to process, and should be skill-based behaviors.
Rule-based behaviors are mostly skill-based behaviors with a conscious cognitive overlay, a planning and thinking of how and what skills to apply to a situation. Such as changing lanes, or aiming a gun with iron-sights ingame.
Knowledge-based behaviors is conscious-level thought and used to problem solve. They are slow and taxing but are used to learn new behaviors.

In relation to my project, it seems from observations that skill-based behaviors should not be spatially-based as these require much practice and are difficult for new players. I noticed a female friend of mine having trouble with the platform movement in Braid (skill-based), but had no problem with the selection and placement skills required in Plants vs. Zombies. She excelled at the rule-based level of choosing and placing good plants, and also at the knowledge-based level of learning and ranking the contextual use of each plant's attributes. A computer requires good mouse use, so all users already have this skill and it would be a benefit to bring that into a game to lessen the learning curve.
