The ability of ten 9-month-old infants with Down syndrome to acquire a contingency in which arm movements were reinforced with auditory and visual stimulation was assessed. Unlike a group of infants without identifiable disabilities, those with Down syndrome did not learn the contingency. Examination of the performance of individual infants with Down syndrome indicated that some infants did master the contingency. In addition, there was a relation between contingency performance and scores on the Mental Development Index of the Bayley Scales of Infant Development. Results were discussed in terms of the possibility that some infants with Down syndrome experience a decline in conditionability with age and the relation between conditionability and mental development.
评估了十名9个月大的唐氏综合征婴儿通过听觉和视觉刺激强化手臂动作来习得一种偶然联系的能力。与一组没有明显残疾的婴儿不同，唐氏综合征婴儿没有学会这种偶然联系。对患有唐氏综合征的个体婴儿的表现进行检查表明，一些婴儿确实掌握了这种偶然联系。此外，偶然联系表现与贝利婴儿发展量表心理发展指数得分之间存在关联。根据一些唐氏综合征婴儿随着年龄增长条件反射能力下降的可能性以及条件反射能力与心理发展之间的关系对结果进行了讨论。
