Pointing, reaching, and other communicative gestures were elicited from 22 children with Down syndrome ages 21 to 47 months in two communicative contexts (referential/declarative vs. instrumental/imperative) and with two partners (mother vs. agemate with Down syndrome). Linguistic competence was assessed using the Vineland and Reynell Scales. High levels of pointing were produced in both communicative contexts and with each partner. Advance visual checking of the partner appeared to indicate awareness of the necessary conditions for successful declarative pointing. Comparisons with matched data from typically developing infants revealed both similarities and differences in gesture use. Findings were discussed in relation to delayed language development in children with Down syndrome.
在两种交流情境（指称性/陈述性与工具性/祈使性）下，让22名年龄在21至47个月的唐氏综合征患儿与两个伙伴（母亲和患有唐氏综合征的同龄伙伴）进行互动，从而引出指向、够取及其他交流手势。使用文兰量表和雷尼尔量表评估语言能力。在两种交流情境下，与每个伙伴互动时，患儿都表现出高水平的指向行为。对伙伴进行预先的视觉检查似乎表明患儿意识到了成功进行陈述性指向的必要条件。将这些结果与正常发育婴儿的匹配数据进行比较，发现了手势使用方面的异同。结合唐氏综合征患儿语言发育迟缓的情况对研究结果进行了讨论。
