Although objects in visual mental images may seem to appear all of a piece, when the time to form images is measured this introspection is revealed to be incorrect; objects in images are constructed a part at a time. Studies with split-brain patients and normal subjects reveal that two classes of processes are used to form images--ones that activate stored memories of the appearances of parts and ones that arrange parts into the proper configuration. Some of the processes used to arrange parts are more effective in the left cerebral hemisphere and some are more effective in the right cerebral hemisphere; the notion that mental images are the product of right hemisphere activity is an oversimplification.
尽管视觉心理图像中的物体看起来可能是一个整体，但当测量形成图像的时间时，这种内省就会被证明是不正确的；图像中的物体是一次构建一部分的。对裂脑患者和正常受试者的研究表明，有两类过程用于形成图像——一类激活存储的部分外观记忆，另一类将部分排列成适当的构型。一些用于排列部分的过程在左脑半球更有效，而一些在右脑半球更有效；认为心理图像是右脑半球活动产物的观点是一种过度简化。
