遵循最初由 [Kosslyn, S. M. (1987) 制定的视觉空间处理的坐标和分类原则的理论框架。大脑半球的观察和想象：AQ 计算方法。 Psychology Review, 94, 148-175]，我们使用经典的 [Shepard, R. N., & Metzler, J. (1971)] 提供了关于心理旋转的功能磁共振成像研究的数据。三维物体的心理旋转。 Science, 171, 701-703] 任务，比较男性和女性。向受试者呈现 3D 形状的黑白图，这些图取自 [Shepard, R. N., & Metzler, J. (1971) 开发的一组 3-D 透视图。三维物体的心理旋转。 Science, 171, 701-703]，与二维白条交替作为控制刺激。这些图画成对呈现，为黑色圆形背景上的黑白图画。在一半的试验中，两个 3D 形状是一致的，但以不同的方向描绘，而在另一半的试验中，两个形状是不一致的。对反应准确性和反应时间的分析没有显示出性别之间存在任何显着差异。然而，在顶上小叶（BA 7）中发现了显着的神经元激活簇，在右半球上更强烈，并且在双侧额下回（BA 44/45）中发现了显着的神经元激活簇。男性主要表现出顶叶激活，而女性则表现出次额叶激活。我们认为男性可能偏向于协调处理方法，而女性可能偏向于串行、分类处理方法。 (c) 2006 Elsevier Ltd. 保留所有权利。
Following the theoretical framework of coordinate and categorical principals for visuo-spatial processing, originally formulated by [Kosslyn, S. M. (1987). Seeing and imagining in the cerebral hemispheres: AQ computational approach. Psychological Review, 94, 148-175], we present data from an fMRI study on mental rotation, using the classic [Shepard, R. N., & Metzler, J. (1971). Mental rotation of three-dimensional objects. Science, 171, 701-703] task, comparing males and females. Subjects were presented with black-and-white drawings of 3-D shapes taken from the set of 3-D perspective drawings developed by [Shepard, R. N., & Metzler, J. (1971). Mental rotation of three-dimensional objects. Science, 171, 701-703], alternated with 2-D white bars as control stimuli. The drawings were presented pairwise, as black and white drawings against a black circular background. On half of the trials, the two 3-D shapes were congruent but portrayed with different orientation, in the other half the two shapes were incongruent. Analysis of response accuracy and reaction times did not reveal any significant differences between the sexes. However, clusters of significant neuronal activation were found in the superior parietal lobule (BA 7), more intensely over the right hemisphere, and bilaterally in the inferior frontal gyrus (BA 44/45). Males showed predominantly parietal activation, while the females, in addition, showed inferior frontal activation. We suggest that males may be biased towards a coordinate processing approach, and females biased towards a serial, categorical processing approach. (c) 2006 Elsevier Ltd. All rights reserved.
