半球不对称的流行观点认为，左半球专门用于语言和认知过程和精细的运动控制，而右侧则专门用于视觉空间处理。尽管这种二分法不仅含有真实性，但它是一个过分简化的。分裂患者的实验表明，左半球保留了相对复杂的视觉空间能力，而有利于右半球的不对称性比左右的那些偏爱的不对称能力微妙。考虑视觉感知的建设性性质以及两个半球的视觉系统的组织表明，在代表视觉空间两侧的区域的视觉处理中，不对称可能会相对较晚。我提供了证据表明，右半球可以被认为比左派更“视觉上聪明”，并假设存在着一个“右山脉的解释器”的存在，该意见致力于构建视觉世界的代表。 （c）2003 Elsevier Inc.保留所有权利。
Popular views of hemispheric asymmetry hold that the left hemisphere is specialized for linguistic and cognitive processes and fine motor control, whereas the right is specialized for visuospatial processing. Although this dichotomy contains more than a grain of truth, it is an oversimplification. Experiments with split-brain patients have demonstrated that the left hemisphere retains relatively sophisticated visuospatial abilities, and that the asymmetries that favor the right hemisphere are subtler than those that favor the left. A consideration of the constructive nature of visual perception, and the organization of the visual system in the two hemispheres suggests that asymmetries are likely to arise relatively late in visual processing in areas that represent both sides of visual space. I present evidence in favor of the view that the right hemisphere can be considered more "visually intelligent" than the left, and postulate the existence of a "right-hemisphere interpreter" dedicated to constructing a representation of the visual world.
