110 blind children in Grades 2 through 12 were matched with sighted controls for age, sex, and verbal reasoning ability. Spatial reasoning was compared with nonspatial reasoning ability for the two groups. At each age level, blind children were inferior to sighted children on spatial reasoning, although the two groups did not differ on nonspatial reasoning. Data further support the likelihood that certain interactions with the perceptual environment may be crucial to specific aspects of cognitive functioning in humans.
110名二至十二年级的盲童在年龄、性别和语言推理能力方面与视力正常的对照组进行了匹配。对两组的空间推理能力与非空间推理能力进行了比较。在每个年龄组中，盲童在空间推理方面都不如视力正常的儿童，尽管两组在非空间推理方面没有差异。数据进一步支持了这样一种可能性，即与感知环境的某些相互作用可能对人类认知功能的特定方面至关重要。
