The possibility that some of the common childhood infections lead to unrecognized impairments of neurological function was examined in 43 820 Birmingham children whose intelligence was assessed in the 11-plus examination. Mean verbal reasoning scores were lower for children who had had measles or pertussis than for those who had had neither of these diseases. However, since attack rates and measured intelligence are related inversely to social class, the lower scores of children with measles and pertussis may be due to class differences which are not eliminated completely by standardization for maternal age and birth order. Mean scores were a little higher for children who had had rubella than for those who had not, and it is suggested that this difference may be due to more frequent reporting of the disease by the more intelligent mothers.
在43820名于11岁以上考试中接受智力评估的伯明翰儿童中，研究了一些常见儿童期感染导致未被识别的神经功能损害的可能性。患过麻疹或百日咳的儿童，其平均言语推理分数低于未患过这两种疾病的儿童。然而，由于发病率和测得的智力与社会阶层呈负相关，患麻疹和百日咳儿童的分数较低可能是由于社会阶层差异，而这种差异不会因按母亲年龄和出生顺序进行标准化而完全消除。患过风疹的儿童平均分数比未患过风疹的儿童略高，有人认为这种差异可能是因为较聪明的母亲更频繁地报告这种疾病。
