Sensorimotor adaptation was studied in 23 institutionalized, mentally retarded individuals. This was achieved by recording the pattern of off-target pointing errors resulting from viewing through a 20-diopter prism. The results showed a wide range of individual differences in prism adaptation. The electroencephalogram (EEG) was also recorded from four scalp locations and analyzed by computer to determine EEG intensity, coherence, and phase angle. Correlations between EEG and behavioral scores of prism adaptation revealed a number of significant relationships, especially negative correlations between alpha intensity and prismatic adaptation. These results indicate that patterns of central nervous system activity are meaningful related to sensorimotor capabilities in retarded individuals.
对23名在机构中生活的智力障碍个体进行了感觉运动适应研究。这是通过记录透过20屈光度棱镜观察导致的偏离目标指向误差模式来实现的。结果显示棱镜适应存在广泛的个体差异。还从四个头皮位置记录了脑电图（EEG），并通过计算机分析以确定EEG强度、相干性和相位角。EEG与棱镜适应行为评分之间的相关性揭示了许多显著关系，特别是α波强度与棱镜适应之间的负相关。这些结果表明，中枢神经系统活动模式与智障个体的感觉运动能力有意义地相关。
