The available versions of the Vandenberg and Kuse (1978) Mental Rotations Test (MRT) have physically deteriorated because only copies of copies are available. We report results from a redrawn version of the MRT and for alternate versions of the test. Males perform better than females, and students drawn from the physical sciences perform better than students drawn from the social sciences and humanities, confirming other reports with the original version of the MRT. Subjects find it very hard to perform the MRT when stimuli require rotation along both the top/bottom axis and the left/right axis. The magnitude of effect sizes for sex (which account, on average, for some 20% of the variance) does not increase with increasing difficulty of the task. Minimal strategy effects were observed and females did not perform differently during the menstrual period as opposed to the days between the menstrual periods. Practice effects are dramatic, confirming other reports with the original MRT, and can also be shown to be powerful in a transfer for practice paradigm, where test and retest involve different versions of the MRT. Main effects of handedness on MRT performance were not found.
范登伯格和库斯（1978年）的心理旋转测试（MRT）现有的版本由于只有复印件的复印件，所以在物理上已经损坏。我们报告了重新绘制版MRT以及该测试替代版本的结果。男性表现优于女性，且从物理科学专业抽取的学生比从社会科学和人文专业抽取的学生表现更好，这证实了使用MRT原始版本的其他报告。当刺激需要沿着上下轴和左右轴旋转时，受试者发现执行MRT非常困难。性别效应量的大小（平均约占方差的20%）不会随着任务难度的增加而增加。观察到最小的策略效应，并且与月经周期之间的日子相比，女性在月经期间的表现没有差异。练习效应很显著，这证实了使用MRT原始版本的其他报告，并且在练习转移范式中也可以显示出强大的作用，其中测试和重新测试涉及MRT的不同版本。未发现利手对MRT表现的主要影响。
