This public folder stores the data taken for the study "A pilot study of how the past, present, and future are represented in three-dimensional space" by Yoshiko Yabe and Sachie Yamada. **Screenshots** folder contains the screen captured images taken at the end of tasks. Each participant was required to complete two tasks: the Circle Test (CT) and Sphere Test (ST). Thus, there are two files for each participant. TDF#### in the file name indicates the participant ID. The "CTN" in the file name indicates that the file presents the screen-shot taken at a ST. The "CTT" in the file name indicates that the file presents the screen-shot taken at a CT. The experiments were conducted in Japanese language. Each circle or sphere has a label to indicate the time zone. 過去 means "Past". 現在 means "Present". 未来 means "Future". **summary.csv** shows the summary of the results of all participants (n=31). - chosensize: Chosen sizes. 1: the smallest; 5: the largest - visualsize: On-screen sizes in pixels - position_in_2D: On-screen positions in pixels - position_in_3D: 3D positions in OpenGL unit
