Human actions are often embedded in contexts of social interactions. However, just a few studies that have explored the development of infants' understanding of other people's manual actions do take this variable into account. In this study, 10- and 18-month-old infants were shown three interactive manual actions which the infants could or could not perform themselves. The infants' gaze shifts to the action target were recorded with an eye tracker. The results indicated that 18-month-old infants look faster to the target than their younger counterparts when they observe actions that they can perform themselves. The results suggest that the infants' own capacity to perform an action facilitates understanding of the goal of the action in a social interaction.
人类行为通常嵌入在社会互动的背景中。然而，只有少数研究探索了婴儿对他人手部动作理解的发展过程，这些研究考虑到了这一变量。在这项研究中，10 个月和 18 个月大的婴儿观看了三个可以或不可以自己执行的互动手部动作。使用眼动追踪器记录了婴儿注视动作目标的目光转移。结果表明，当观察自己可以执行的动作时，18 个月大的婴儿比他们的同龄人更快地看向目标。结果表明，婴儿自己执行动作的能力有助于他们理解社会互动中动作的目标。
