The authors investigated the extent to which the joint-attention behaviors of gaze following, social referencing, and object-directed imitation were related to each other and to infants' vocabulary development in a sample of 60 infants between the ages of 8 and 14 months. Joint-attention skills and vocabulary development were assessed in a laboratory setting. Split-half reliability analyses on the joint-attention measures indicated that the tasks reliably assessed infants' capabilities. In the main analysis, no significant correlations were found among the joint-attention behaviors except for a significant relationship between gaze following and the number of names in infants' productive vocabularies. The overall pattern of results did not replicate results of previous studies (e.g., M. Carpenter, K. Nagell, & M. Tomasello, 1998) that found relationships between various emerging joint-attention behaviors.
作者对60名8至14个月大的婴儿进行了研究，调查了注视跟随、社会参照和目标指向性模仿等联合注意行为之间的关联程度，以及它们与婴儿词汇发展的关系。联合注意技能和词汇发展在实验室环境中进行评估。对联合注意测量的分半信度分析表明，这些任务能够可靠地评估婴儿的能力。在主要分析中，除了注视跟随与婴儿产出性词汇中的名称数量之间存在显著关系外，未发现联合注意行为之间存在显著相关性。结果的总体模式并未重复先前研究（如M. Carpenter、K. Nagell和M. Tomasello，1998）的结果，先前研究发现各种新兴联合注意行为之间存在关系。
