This study looked at the performance on the Griffiths Mental Development Scales of 149 middle-class children, aged 6-60 months, from three suburban neighborhoods in Kingston, Jamaica. Their mean DQs were higher than the English standardisation sample. The high scores below 2 years were similar to those reported from black children elsewhere. After 2 years the scores fell into the general range reported for middle-class children from other countries. The children had relatively high hearing and speech scores and low performance scores. Girls scored higher than boys, but birth order and maternal age were not associated with DQs.
本研究观察了来自牙买加金斯敦三个郊区社区的149名6至60个月大的中产阶级儿童在格里菲斯心理发展量表上的表现。他们的平均发育商高于英国标准化样本。2岁以下儿童的高分与其他地方黑人儿童的报告结果相似。2岁以后，分数落入其他国家中产阶级儿童报告的一般范围内。这些儿童的听力和言语分数相对较高，而操作分数较低。女孩得分高于男孩，但出生顺序和母亲年龄与发育商无关。
