A survey of mental rotation strategies in 210 normal subjects showed a strong tendency for right-handers to prefer rotating an object on the right and vice versa for left-handers. The differential functioning of the cerebral hemispheres during mental rotation was then assessed in 42 subjects by means of tachistoscopic presentation of two geometrical figures separately to the left and right visual fields--one of which was gravitationally stable and the other unstable. Performance was better when the unstable object was presented to the right visual field and the stable object to the left. This finding is interpreted as indicating more efficient hemispheric cooperation when the active manipulation of a mental image is performed by the left hemisphere, while the reference role is carried out by the right hemisphere.
一项针对210名正常受试者的心理旋转策略调查显示，右利手者强烈倾向于在右侧旋转物体，而左利手者则相反。随后，通过向42名受试者的左、右视野分别快速呈现两个几何图形（其中一个在重力作用下稳定，另一个不稳定）的方式，评估了心理旋转过程中大脑半球的不同功能。当不稳定物体呈现给右视野，稳定物体呈现给左视野时，表现更好。这一发现被解释为，当左半球对心理图像进行主动操作，而右半球发挥参考作用时，半球间的合作更高效。
