心理旋转可以被认为是一种非符号的、类比的、与命题相反的高阶转换过程的原型。因此，这是一个范例的情况下，测试的观点，这些属性基本上是右半球。证据脑成像，单侧脑病变，commissurotomy，和视觉半野差异正常人进行审查。尽管有一些证据支持右脑偏向，至少是对相对简单的图形的整体旋转的偏向，但这种偏向不太可能接近左脑在语言相关技能方面的优势程度。一个进化的情况下，描绘了典型的符号模式的左半球发展相对较晚，并实现了递归生成的质量，只有在晚期阶段的原始人进化。这就迫使右脑对心理旋转等模拟过程产生越来越大的偏见。然而，这些过程仍然很重要，甚至是那些我们认为具有高度象征意义的过程（如语言和数学）的组成部分。(C)北京：科学出版社.
Mental rotation may be considered a prototypical example of a higher-order transformational process that is nonsymbolic and analog as opposed to propositional. It is therefore a paradigm case for testing the view that these properties are fundamentally right-hemispheric. Evidence from brain-imaging, unilateral brain lesions, commissurotomy, and visual-hemifield differences in normals is reviewed. Although there is some support for a right-hemispheric bias, at least for the holistic rotation of relatively simple shapes, it is unlikely that this bias approaches the degree of left-hemispheric dominance for language-related skills. An evolutionary scenario is sketched in which the characteristically symbolic mode of the left hemisphere evolved relatively late and achieved the quality of recursive generativity only in the late stages of hominid evolution. This forced an increasingly right-hemispheric bias onto analog processes like mental rotation. Such processes nevertheless remain important and are integral even to those processes we think of as highly symbolic,such as language and mathematics. (C) 1997 Academic Press.
