Abstract: A stereographic mental cutting test (hereafter SMCT) was conducted to analyze 3D spatial abilities evaluated by a standard mental cutting test (hereafter MCT). The results of the analysis indicated that the MCT mainly reflects the abilities in making and manipulating three-dimensional mental images. The results also indicated that the subjects came to recognize 3D shapes more easily by using stereograms. However, the stereograms did not have any effect on complicated mental image processing tasks such as transformation of a section to a true shape view. Also, low scoring subjects in this study could not recognize the test solid and its cutting plane well, and they were unable to form correct images of objects, even when they used stereograms.
