The rules presented here form a grammar of problem solving with a definitive syntax. There is no doubt about its validity as a reliable problem solving tool. It is also a subject area for additional research in the matters of cognition and logical thinking. In the study of the intellectual processes involved in solving problems some basic mechanisms have been identified.
Selective encoding requires sifting out relevant from irrelevant information.
In a logical problem solving framework this is a recursive process. The initial step of a problem solution consists of responding to the specific question asked, while ignoring all of the given material. This first step requires stating a concept that is the answer to the question asked quite independent of the details of the problem. A true, basic, simple response is the goal. In this way the process of selective encoding is automated.
