Description
Summary:"A group of 602 children in sight-conservation classes was tested by the New Revised Stanford-Binet Test. The visual material of the test was enlarged so as to avoid any possible handicap due to visual defect . . . . Numerous retests at varying intervals were given, some with the standard material, and some with the enlarged. The mean for the 602 cases tested with the Enlarged Binet was 95.1. When divided into groups according to the amount of vision, no difference in means was found between those having better than 20/70 vision and those whose vision was from 20/70 to 20/200. A study of previous IQ's obtained from many different kinds of tests dating back for varying lengths of time and given by many different examiners showed on the whole lower IQ's than those obtained by the Enlarged Test. The suggestion here is that these partially-sighted children are probably handicapped in taking the usual standard group intelligence tests. In all probability the mean IQ for partially sighted children in sight-conservation classes is only a few points below normal--somewhere in the neighborhood of 96 or 97. It is interesting to note that this mean is about the same as that found for hard-of-hearing children."
