Through the theoretical analysis of the hierarchy of receivers' cognitive laws and the communicating effect of video and acoustic works, based on the creation of digital agriculture which is a science film, this article reaches the following conclusions: The creation of video and acoustic works is closely related to the receivers' cognitive structure, the communicating effect of scientific video and acoustic works is directly related to the harmony of receivers' cognitive structure and laws. It means that receivers' psychology, care degree or the awareness (selective attention) to the information is the base of receivers' understanding (selective perception) of works. The receivers' understanding (selective perception) is the step of their acceptance and belief (Selective Retention), their acceptance and belief (Selective Retention) is the result of information accepting. During the process of creating scientific video and acoustic works, we should concern about the subject-researches, clean the creation goal, take a look at the content location and scientific intension, care more about the receivers' cognitive laws and narrative techniques, effort to make the harmonious mutual interaction between the works' value and receivers' soul, thus to edify people to love science, understand science, master scientific technology, improve people's scientific literacy.
