The hierarchical levels of information activities in the subject's psychology and cognition.

The subject's psychological and cognitive activities are important interdisciplinary issues in psychology, cognitive science, and philosophy. The Chinese philosophy of information innovatively provides a philosophical definition of the concepts of subject and object from the dimension of information activity, while also making specific provisions for the cognitive activities of the subject. The subject's psychology and cognition are an activity of advanced grasping and creation of information. The subject's information activities have five basic levels. Arranged from lower to higher, they are: the subject's in-itself information activities, the subject's intuitive discernment of information, the subject's memory storage of information, the subject's subjective creation of information, and the subject's practice and social realization of information. Higher-level information activities must arise on the basis of lower-level ones. Therefore, the emergence and development of the subject's psychology and cognition necessarily constitute a highly integrated and complex process of information activities.
