12-month-old infants with Down syndrome (n = 14) and mental and motor age-matched high-risk preterm infants (n = 14) were studied with respect to their ability to attend to and explore their environment in interactions with their mothers. The effectiveness of particular maternal attention-directing techniques in modifying infant responses to toys was expected to vary across the 2 infant groups. In general, higher-level responses to toys were expected to be associated with mother's attempts to maintain rather than redirect the child's attention and the mother's use of structured verbal and nonverbal attention-directing techniques. Results indicated that mothers of the 2 groups of infants used different attention-directing strategies, and their use of particular strategies was differentially related to the attentional capacity of the 2 groups. Differences in the infants' responses to particular maternal strategies were related to the amount of structure provided and to the demands placed on their capacity to shift attention between objects. Fewer specific maternal techniques for directing attention elicited higher-level play behavior from the Down syndrome infants, compared to the preterm group.
对14名患有唐氏综合征的12个月大婴儿和14名心理与运动年龄匹配的高危早产儿进行了研究，观察他们在与母亲互动时关注和探索环境的能力。预计特定的母亲注意力引导技巧在改变婴儿对玩具的反应方面的有效性在这两组婴儿中会有所不同。一般来说，对玩具的更高水平反应预计与母亲试图维持而非重新引导孩子的注意力以及母亲使用结构化的言语和非言语注意力引导技巧有关。结果表明，两组婴儿的母亲使用了不同的注意力引导策略，并且她们对特定策略的使用与两组婴儿的注意力能力存在不同的关联。婴儿对特定母亲策略的反应差异与所提供的结构化程度以及对他们在物体之间转移注意力能力的要求有关。与早产组相比，唐氏综合征婴儿对母亲引导注意力的特定技巧反应较少，却引发了更高水平的玩耍行为。
