The purpose of this study was to explore the influence of physical and aesthetics attributes in urban sculpture sites on users' emotional experiences. Physical attributes are:two catalogues of outdoor space area--larger than 100 m�� and, two smaller than 100 m�� catalogues of sculpture dimension--the multiplication of the maximum width and height larger than 20 m�� and smaller than 20 m��, as well as two kinds of sculpture material--metal and stone have been examined as the factors associated with emotional experiences. Aesthetic attributes are theme, simplicity, mass, complexity, technology, balance and contrast. The emotional experience survey was conduct right on the spots, which was selected according to the investigatin of sculpture sites in Taipei. The aesthetic scores were obtained from professional sculptors. Study results are summarized as follows: 1.Four fundamental emotional experiences are found through factor analysis. They are distressing--fearful, leisurely--calm, exhilarating--joyful, and disorder--awful. 2.Whatever on the larger or smaller spaces, the strongest emotional response toward the larger sculptures was 'exhilarating--joyful'. Thestrongest emotional response toward the smaller sculptures was 'leisurely--calm'. 3.The correlation between the degrees of aesthetic attributes and emotional responses only happened on 'exhilarating-joyful' for all study sites. Characters about theme, technology and contrast of sculpture would lead to this emotional experience. In different catalogues of physical situation of sculpture site status, aesthetic attributes would have correlation with different emotional experiences.
