两组18个月大的婴儿在一个相对自然的游戏过程中与一个成年实验者和几个玩具。实验者使用注意力跟随策略（即，当婴儿专注于渡渡鸟物体时引入标签）或注意力转换策略（即，当婴儿专注于替代物体时引入标签）。随着诸如暴露于对象标签的频率和各组婴儿的依从性等因素，注意力跟随程序中的婴儿更有可能在随后的理解任务中正确识别渡渡鸟对象。这些实验数据证实了以前的相关性观察表明，早期词汇的发展是促进在互动中，照顾者是以下，而不是导致婴儿的注意力的焦点。
Two groups of 18-month-old infants were observed during a relatively natural play session with an adult experimenter and several toys. A novel object associated with one of the toys was labeled a dodo by the experimenter using either an attention-following strategy (i.e., introducing the label when the infant was focused on the dodo object) or an attention-switching strategy (i.e., introducing the label when the infant was focused on an alternative object). With factors such as frequency of exposure to the object label and infant compliance equivalent across the groups, infants in the attention-following procedure were more likely to correctly identify the dodo object in a subsequent comprehension task. These experimental data corroborate previous correlational observations suggesting that early lexical development is facilitated during interactions in which the caregiver is following rather than leading the infant's focus of attention.
