This is an examination of the effect of elements of the space to people's action. The combination of the wallpaper and the color temperature of lighting of the space changes the impression of the space. But, it is not obvious whether the effect works on people's action or not. So, we investigated people's action, evaluating a chocolate in an exhibition space and estimated the effect of combination of the wallpaper and the lighting by the evaluation of a chocolate. In the experiment, participants were told to evaluate chocolates, and we compared the result by the difference of the wallpaper and the color temperature of lighting of the space. The reason to use such a method is that people can't speak about the real intention of their actions. By the experiment, we discovered that however participants were not aware, the difference of the wallpaper and the lighting of the space affected the intention to purchase the chocolate in some case.
