Six-month-old infants with Down syndrome (n = 14) and mental and motor-age-matched high-risk preterm infants (n = 15) were studied with respect to their use of separate attentional processes under conditions with and without their mother's direct involvement in play. As predicted, compared to preterm infants, the infants with Down syndrome spent less time involved with toys and more time looking at their mothers whether or not their mothers were actively involved. Although both infant groups showed an increase in the amount of time spent attending to toys in the mother-involved condition compared to the independent condition, only the preterm infants examined a wider range of toys when interacting with their mothers. Also, the infants with Down syndrome showed fewer shifts of attention to a toy in response to their mother's attempts to redirect their attention and, unlike the preterm infants, did not show increased positive affect when interacting with their mothers compared to playing on their own.
对14名患有唐氏综合征的6个月大婴儿和15名心理与运动年龄匹配的高危早产儿进行了研究，观察他们在母亲直接参与玩耍和不参与玩耍的条件下对不同注意力过程的运用情况。正如预期的那样，与早产儿相比，患有唐氏综合征的婴儿无论母亲是否积极参与，他们玩玩具的时间都更少，而看向母亲的时间更多。虽然与独立玩耍的情况相比，两个婴儿组在母亲参与的情况下玩玩具的时间都有所增加，但只有早产儿在与母亲互动时检查了更多种类的玩具。此外，患有唐氏综合征的婴儿在母亲试图转移他们的注意力时，对玩具的注意力转移较少，而且与早产儿不同的是，与自己玩耍相比，他们在与母亲互动时并没有表现出更多的积极情绪。
