ABSTRACT
Introduction
We studied protocols of learning a new problem and observed two kinds of meta-cognitive attentions, i.e. orientational attention and selective attention. Scopes of these attentions are different in activities. When people confront with a new problem, it is required to regulate weakly coupled activities, such as making better understanding of the problem through experiences and finding immediate solutions using heuristics. Orientational attention is the meta-cognition on this regulation of multiple activities, whereas selective attention is a meta-cognition on reasoning in each activity.
