The present study provides evidence for congenitally blind people's ability to generate visuo-spatial images, and explores its limitations. Congenitally blind and sighted participants were asked to memorize the spatial positions of target objects (cubes) in two- and three-dimensional matrices, while simultaneously performing a sequence of spatially based imagery operations. Furthermore, during half of the trials, subjects were required to perform an articulatory suppression task. Although articulatory suppression affected both groups to the same extent, congenitally blind people performed poorly with more demanding spatial tasks and when an active elaboration was required.
本研究为先天失明者生成视觉空间图像的能力提供了证据，并探讨了其局限性。研究要求先天失明和有视力的参与者记住目标物体（立方体）在二维和三维矩阵中的空间位置，同时执行一系列基于空间的图像操作。此外，在一半的试验中，要求受试者执行言语抑制任务。尽管言语抑制对两组的影响程度相同，但先天失明者在更具挑战性的空间任务以及需要积极加工时表现较差。
