Abstract
The nature of superiority of paper media lies in the affinity of paper with human being. Developmental psychology theory suggests that the appeal of paper to human sensation and perception as well as the capability of paper of storing the meaning of sentence into the cognitive structure of individual brain deeply and stably are innate nature. Therefore, paper media will maintain its superiority in the formation of individual knowledge even in the digital age. As for the hedonic value as an indicator of human affinity, the hedonic value of paper is higher and will boost cognition processes. On the contrary, the hedonic value of electronic displaying devices at the current stage is insufficient and will inhibit cognition processes. According to the Affordance theory, the body sensation and cultural environment in the interaction between media and human being will affect cognition processes, the object's shape and various sensation other than visual one in the reading of paper-based book or electronic book will affect cognition processes. For further elucidation of this issue, the cognitive science will be a powerful tool.
