We assessed infant's gaze in a teasing task in New York City public spaces. The task was administered to two different groups of 5- to 13-month-old infants. We used a between participants design across two studies. In Study 1 an experimenter administered the task to these infants (n = 79), whereas a parent did so in Study 2 (n = 79). The adult engaged the infant with a toy and then pulled it away to one side by counting to 7. A second trial to the other side was repeated. Infants passed the teasing task if they looked to the adult's face within the first 5 seconds after removing the toy in at least one trial. In Study 1, we found that infants looked to the experimenter's face after teasing by 7 months of age. In Study 2, infants did not show any significant gazes to the parent's face after teasing at any age. Most trained parents successfully administered the teasing task to their infant. A teasing game played by an adult stranger (e.g., experimenter) may be optimal to elicit infant's gaze in a naturalistic setting. Implications for developing cost-effective social-cognitive milestone measures in non-laboratory settings are discussed.
我们在纽约市公共场所评估了婴儿在逗弄任务中的注视情况。该任务针对两组 5 至 13 个月大的婴儿进行。我们在两项研究中使用了参与者之间的设计。在研究 1 中，一名实验员对这些婴儿（n=79）进行了任务，而在研究 2 中，一名家长对婴儿（n=79）进行了任务。成人用玩具与婴儿互动，然后在数到 7 后将玩具拉到一侧。重复另一侧的第二次试验。如果婴儿在移除玩具后的头 5 秒内至少有一次看向成人的脸，那么他们就通过了逗弄任务。在研究 1 中，我们发现婴儿在 7 个月大时会在被逗弄后看向实验员的脸。在研究 2 中，在任何年龄段，婴儿在被逗弄后都没有看向父母的脸。大多数受过训练的父母都能成功地对婴儿进行逗弄任务。成年人（例如实验员）玩的逗弄游戏可能是在自然环境中引发婴儿注视的最佳方式。本文讨论了在非实验室环境中开发具有成本效益的社会认知里程碑测量方法的意义。
