We successively think through conceptual changes in the sketching process and this forms the foundation of the creative thinking process. Sketching is a visualization tool of recognizing and reinterpreting to find the resolution to a design problem, and most of the studies have been regarded in the results or the apparent meanings of sketches. However, we aim to observe conceptual changes in the sketching process and report the aspects of these changes using the intrinsic attributes of the concepts. This study is original in that it reveals that attribute changes can induce overall categorical changes in concepts in the goal problem. This investigation consists of observations of college students’ sketching and interviews with them. The research data was analyzed using protocol analysis and Linkography. During the sketching process, attributes of sketches enable categorical changes, which qualitatively transform the existing forms of cognition into those with completely different concepts.
