Resumen
We have conducted several experiments where various types of information offering strategies were performed. We obtained interesting phenomena from the results. The participants seemed to be able to gradually understand the artwork by offering information of the artwork. Of course, for an abstract art, the information of the artworks functions better understanding of artworks. Even for a representational painting, the quality and quantity of understanding was gradually changing. Thus, the information of art sometimes influences the art appreciation. In this paper, we will discuss how the value and preference of art will change according to offered information? In addition, we will discuss determining which factor (information) will change the viewers? value and preference of art in the art appreciation. For that, we conducted two experiments, where information of the artwork was offered randomly (each person may obtain different information for the artswork). Additionally, for all the artworks, the information was offered in the same manner (all persons will obtain the same information for the artworks). The information involved title, painting materials, techniques, production year, name of artist, price, background, and theme of the artworks.
