To investigate whether children with Down syndrome are less careful in performing motor tasks than children with other types of mental retardation, a tray-carrying task was devised in which subjects carried a tray bearing a glass filled with water which they tried not to spill. This task was given to children with Down syndrome (6 boys and 4 girls, n = 10) and those with other types of mental retardation (9 boys and 9 girls, n = 18; most of them diagnosed as undifferentiated). Mean chronological ages in the groups were 15.4 yr. for the Down group, and 16.3 yr. for the Mental retardation group. Mental ages were the same in both groups: 4.8 yr. The performance of children with Down syndrome was not significantly different from that of other children as measured by the amount of water spilled. Children with Down syndrome required more time and took more steps than the other children, although the time taken for each step was the same in both groups. The strategy of children with Down syndrome appeared to be to make each unit of movement smaller to carry out the given motor task.
为了研究唐氏综合征患儿在执行运动任务时是否比其他类型智力障碍的儿童更粗心，设计了一项托盘搬运任务，让受试者搬运一个装有一杯水的托盘，且尽量不让水洒出。这项任务被分配给唐氏综合征患儿（6名男孩和4名女孩，n = 10）以及其他类型智力障碍的儿童（9名男孩和9名女孩，n = 18；他们中的大多数被诊断为未分化型）。两组儿童的实际年龄平均为：唐氏综合征组15.4岁，智力障碍组16.3岁。两组儿童的心理年龄相同：4.8岁。通过洒出的水量来衡量，唐氏综合征患儿的表现与其他儿童没有显著差异。唐氏综合征患儿比其他儿童需要更多时间和更多步数，尽管两组每一步所用时间相同。唐氏综合征患儿的策略似乎是使每个动作单元更小，以完成给定的运动任务。
