Many studies on mathematical problem solving focus on some activities such as "looking back", "metacognition", "self-assessment", "reflection" and so on. These activities have a point in common; that is "when problem solver engages himself/herself in the activity, he/she refers to his/her own processes or products of the problem-solving activity". But the names and conceptions of these activities are sometimes various and ambiguous. In this series of studies, we generally grasp these activities as "self-referential activities", and aim to elaborate on the conception, structure, and role of these self-referential activities during problem solving.
At the beginning of these studies, this article aims at constructing a framework for conceptualizing the self-referential activities systematically. First of all, we hypothesize self-referential architecture of human intelligence. This is the same concept of Skemp's reflective intelligence which is defined as the "ability to make one's own mental processes the object of conscious observation" (Skemp, 1979, p.175). This self-referential/reflective function of intelligence (we temporarily call it just "self-referential ability" or just "self-reference" in this article) could make the point in common among these self-referential activites. According to this hypothesis, we propose the framework for conceptualizing the self-referential activities as the following; i.e., each self-referential activity emerges, when this hypothesized self-referential mental function (self-referential ability) takes some variables.
The significant variables are drawn from preceding studies on "metacognition", "looking back", "self-assessment", "reflection" as follows.
(1) Ongoing (OG)/Not-Ongoing (NOG): Metacogintion occurs in ongoing process of solving problems or cognitive tasks. And the ongoing process implies a phase of problem-solving behavior that is formed out of solver's intended goal.
(2) Monitor -> Self-Evaluation (M-SE)/Self-Evaluation -> Control (SE-C): Metacognition emerges as the process "monitor -> self-evaluation -> control" and self-assessment is characterized by two components; i.e., self-awareness corresponding to the process "monitor -> self-evaluation" and self-evaluation corresponding to the process "self-evaluation -> control". They characterize both metacognitive process and self-asssessment.
(3) Until-the-End-of-Problem-Solving (UEPS)/After-the-End-of-Problem-Solving (AEPS): Problem-solving activity is significantly distinguished between the process until production of an answer for the given problem and the process after production of it. So the point of the production of an answer for the given problem become a variable (as a divide in problem solving) of self-referential activities.
(4) Process (PROC)/ Product (PROD): In our definition of self-referential activities, we grasp them as such activities that "problem solver refers to his/her own processes or products of the problem-solving activity". When one engages himself/herself in the self-referential activities, he/she ought to have objects that he/she refers to. Thus we draw the variable, process/product, as a distinction among the objects of self-reference.
By these four variables, we can construct the framework for conceptualizing the self-referential activities as the following;

In this article, the reasonability of this construction is shown by eight concrete self-referential activities (which is restricted to the variable "UEPS").
