Being key factors in plastic arts, shapes and colors can both successfully reflect individual emotions. For several years, children's drawings have been a factor in the investigation of mental development. However, only a few studies have focused on a systematic psychological analysis of plastic images. This research from the viewpoint of art psychology used a survey questionnaire to study the emotional images elicited by shapes and colors. The subjects were students at Shie-he Elementary School in Taichung, Taiwan. From an analysis of the results of this survey, three conclusions were reached: 1. Among elementary-school students, responses to the color of an image are more remarkable than to the shape of the image. 2. The results reveal that different colors can be related to different emotional images, such as red to love, black to fear and white to sorrow. 3. Yellow, green, blue and purple are related to both happiness and surprise; moreover, these four colors are influenced by the shape of the image. The findings of this study can be applied to both diagnosis and counseling in teaching the psychology of plastic arts and art education in general.
