The participants judged whether two successively presented geons (Biederman, 1987) were the same or different. The geons were presented with different rotation angles (0°, 30°, and 60°) through a haploscope. In the qualitatively changed condition the visible qualitative information of the geons was changed by rotation. In the quantitatively changed condition only quantitative information was changed by the rotation. Half of the participants observed the geons with binocular disparity (3D condition). The other half observed the geons without disparity (2D condition). In the 2D condition the reaction time (RT) increased with the rotation in both of the changed conditions. The error rate in the qualitatively changed condition was increased with the rotation, but the error rate of the quantitatively changed condition was unaffected. On the other hand, in the 3D condition the RT and error rate in both of the changed conditions were not affected by the rotation. Furthermore, the RT in the 3D condition was shorter than the 2D condition. These results suggested that binocular depth information plays a crucial role in view-independent, structural object representation.
