Congenitally blind individuals are generally less accurate at mentally manipulating objects than sighted people. However, they often score higher on tests of short- and long-term verbal memory, and it has been suggested that an enhanced propositional representation compensates for inefficiencies in analogue visuospatial representation. Here, congenitally blind, blindfolded, and sighted participants recalled descriptions of relative object locations. In contrast to previous findings, the congenitally blind participants were as accurate as the blindfolded and sighted individuals at remembering the relative locations of objects, but their memory for the verbatim structure of presented descriptions was worse. We propose that, like sighted people, the congenitally blind spontaneously construct and remember analogue representations of object locations and that the performance discrepancies of the blind arise from the process of managing and manipulating these analogue representations.
与有视力的人相比,先天性盲人在对物体进行心理操作时通常准确性较低。然而,他们在短期和长期言语记忆测试中的得分往往更高,有人认为增强的命题表征弥补了模拟视觉空间表征的低效。在这里,先天性盲人、蒙眼者和有视力的参与者回忆了物体相对位置的描述。与之前的研究结果相反,先天性盲人参与者在记住物体相对位置方面与蒙眼者和有视力的人一样准确,但他们对所呈现描述的逐字结构的记忆较差。我们提出,与有视力的人一样,先天性盲人会自发构建并记住物体位置的模拟表征,而盲人在表现上的差异源于管理和操作这些模拟表征的过程。
