Educable mentally retarded children were randomly assigned to either a visual-spatial training condition or a control group. The children who received training showed a gain from pretest to posttest on the Children's Embedded Figures Test that corresponds to approximately 4 years of maturation in nonretarded children. The performance of the children in the control group on the posttest was not significantly different from their performance on the pretest. Correlations between measures of visual-spatial ability and the employment adjustment of retarded persons obtained by other investigators suggest the potential importance of developing the visual-spatial skills of this population.
可教育的智力迟钝儿童被随机分配到视觉空间训练组或对照组。接受训练的儿童在儿童镶嵌图形测验中,从前测到后测有进步,这相当于非智力迟钝儿童大约4年的成熟度提升。对照组儿童在后测中的表现与前测表现没有显著差异。其他研究者得出的视觉空间能力测量与智力迟钝者就业适应之间的相关性表明,培养这一人群的视觉空间技能具有潜在的重要性。
