In the current study, 24- to 27-month-old children (N = 37) used pointing gestures in a cooperative object choice task with either peer or adult partners. When indicating the location of a hidden toy, children pointed equally accurately for adult and peer partners but more often for adult partners. When choosing from one of three hiding places, children used adults' pointing to find a hidden toy significantly more often than they used peers'. In interaction with peers, children's choice behavior was at chance level. These results suggest that toddlers ascribe informative value to adults' but not peers' pointing gestures, and highlight the role of children's social expectations in their communicative development.
在当前的研究中，24 至 27 个月大的儿童（N=37）与同伴或成人伙伴在合作物体选择任务中使用了指向手势。当指示隐藏玩具的位置时，儿童对成人和同伴伙伴的指向准确性相等，但更常指向成人。当从三个隐藏地点中选择时，儿童使用成人的指向来找到隐藏的玩具的次数明显多于同伴。在与同伴的互动中，儿童的选择行为是随机的。这些结果表明，幼儿认为成人的指向手势具有信息价值，而不是同伴的指向手势，并且强调了儿童的社会期望在其交流发展中的作用。
