视觉意象是否涉及视觉知觉中使用的一些相同的表征？认知心理学家收集的支持这一说法的证据受到了三种类型的替代解释的挑战：隐性知识，根据该知识，受试者在视觉系统隐性知识的指导下，在意象任务中使用非视觉表征来模拟视觉表征的使用；实验者期望，根据实验者期望，暗示意象和知觉的共同表征的数据是实验者期望的产物；以及非视觉空间表征，根据这种说法，图像表征在编码空间关系的方式上部分类似于视觉表征，但不是视觉表征。本文回顾了以前被忽视的关于意象和知觉之间关系的神经心理学证据，并讨论了它对上述替代解释的相对免疫力。这一证据包括电生理学和脑血流研究，这些研究定位了大脑皮层视觉区域在成像过程中的活动，以及脑损伤对视觉感知和成像的选择性影响之间的相似性。因为这些发现不能像传统认知数据那样使用前面列出的替代解释来解释，所以它们可以在回答标题问题方面发挥决定性作用。（PsycINFO数据库记录(c) 2016 APA，版权所有）
Does visual imagery engage some of the same representations used in visual perception? The evidence collected by cognitive psychologists in support of this claim has been challenged by three types of alternative explanation: Tacit knowledge, according to which subjects use nonvisual representations to simulate the use of visual representations during imagery tasks, guided by their tacit knowledge of their visual systems; experimenter expectancy, according to which the data implicating shared representations for imagery and perception is an artifact of experimenter expectancies; and nonvisual spatial representation, according to which imagery representations are partially similar to visual representations in the way they code spatial relations but are not visual representations. This article reviews previously overlooked neuropsychological evidence on the relation between imagery and perception, and discusses its relative immunity to the foregoing alternative explanations. This evidence includes electrophysiological and cerebral blood flow studies localizing brain activity during imagery to cortical visual areas, and parallels between the selective effects of brain damage on visual perception and imagery. Because these findings cannot be accounted for in the same way as traditional cognitive data using the alternative explanations listed earlier, they can play a decisive role in answering the title question.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
