我们调查了婴儿在“无意中听到”的情况下是否理解他人对第三人称的非语言交际意图。一名实验人员对一名助手说话，并通过假装凝视或为她指出隐藏玩具的位置来指示她。在一个匹配的控制条件下，实验者表现出类似的行为（心不在焉地凝视和伸出食指），但不与助手进行表面上的交流。然后婴儿就可以寻找玩具。18个月大的婴儿可以熟练地使用两种交流线索来找到隐藏的物体，而14个月大的婴儿只使用指向线索。在控制条件下，两个年龄组的表现都不高于机会。因此，这项研究表明，在14-18个月大的时候，婴儿开始监控和理解第三方互动的某些方面。(C) 2008爱思唯尔公司版权所有。
We investigated whether infants comprehend others' nonverbal Communicative intentions directed to a third person, in an 'over-hearing' context. An experimenter addressed an assistant and indicated a hidden toy's location by either gazing ostensively or pointing to the location for her. In a Matched control condition, the experimenter performed similar behaviors (absent-minded gazing and extended index finger) but did not Communicate ostensively with the assistant. Infants could then search for the toy. Eighteen-month-old infants were skillful in using both communicative Cues to find the hidden object, whereas 14-month-olds performed above chance only with the pointing cue. Neither age group performed above chance in the control condition. This study thus shows that by 14-18 months of age, infants are beginning to monitor and comprehend some aspects of third party interactions. (C) 2008 Elsevier Inc. All rights reserved.
