The present study investigated the effects of public art on visual properties and affective appraisals of landscapes. Undergraduate and graduate students sequentially viewed landscapes with or without public art and rated each one for visual properties and affective appraisals. Study 1 revealed that the presence of public art reduced pleasantness of the natural scene, but did not reduce that of the urban scene. In Study 2 focusing on the urban landscapes, the t-tests showed that public art consistently yielded greater arousal and the visual properties related with arousal level (e.g., complexity), whereas for pleasantness and the visual properties related with pleasantness (e.g., legibility) the scores varied with the public artworks. Adopting the experimental design that systematically combined 4 landscapes with 2 pieces of public art, Study 3 revealed that the affective quality of public art had more influence on the landscapes than the compatibility between public art and the landscapes.
