The effect of institutionalization was measured in relation to performance on the Cattell Infant Intelligence Scale by 103 profoundly retarded residents with a mean CA of 20.3 years, a mean MA of 18.1 months, a mean IQ of 12.7, and a mean number of years in the institution of 10.6. After partialing out CA and MA, years in the institution was negatively correlated with success in visually directed object manipulation (Cattell items below an MA of 9 months), social imitation (9-12 months), and purposeful, constructive activities (over 20 months). The findings were compared with previous studies on retarded and nonretarded infants and children.
通过对103名重度智力发育迟缓居民进行研究，测量机构收容对其在卡特尔婴儿智力量表上表现的影响。这些居民的平均实际年龄为20.3岁，平均心理年龄为18.1个月，平均智商为12.7，在机构中的平均收容年限为10.6年。在排除实际年龄和心理年龄的影响后，在机构中的收容年限与视觉引导下的物体操作（心理年龄低于9个月的卡特尔项目）、社会模仿（9 - 12个月）以及有目的的建设性活动（超过20个月）的成功与否呈负相关。研究结果与之前关于智力发育迟缓及非智力发育迟缓婴幼儿的研究进行了比较。
