| Summary: | The effect of stereo television presentation on “mental rotation” was examined. When the orientations of two identical or mirror figures are changed and then displayed, mental rotation is the phenomenon that the time taken to decide this difference is proportional to the angular difference between the orientations of the two figures. First, the reaction times when the presentations were in two and three dimensions were compared, and the effectiveness of the three‐dimensional presentation was studied. The result was that, even when displayed in three dimensions, a mental rotation similar to that of the two‐dimensional case was verified and the reaction time was significantly shortened. The result of studying the internal processes showed that three‐dimensional presentation was effective from the standpoint of the transformation to the internal representation. The subjects were divided into two groups based on their reaction times. When the effectiveness of the three‐dimensional presentation was studied, three‐dimensional presentation was particularly effective for the group with the short reaction times. Furthermore, when a part of the presentation figures were marked with color, the speed for rotating the representation became significantly faster regardless of the presentation dimension. By studying the subjects, we found colored marking was effective for subjects with long reaction times. |
