Infants readily re-enact others' intended actions during the second year of life. However, the role of emotion in appreciating others' intentions and how this understanding develops in infancy remains unstudied. In the present study, 15- and 18-month-old infants observed an experimenter repeatedly attempt but fail to produce a target action on an object and express either frustration or neutral affect after each attempt. Analyses of infants' responses revealed that 18-month-old infants, but not 15-month-olds, produced more target actions in the frustration condition than the neutral condition. These results suggest that infants use emotional communication to disambiguate and re-enact others' intended actions and that this ability develops in the second year of life.
婴儿在生命的第二年很容易模仿他人的意图行为。然而，情感在理解他人意图中的作用以及这种理解在婴儿期是如何发展的，这方面的研究仍未开展。在本研究中，15 个月和 18 个月大的婴儿观察到实验者反复尝试但未能成功地在物体上产生目标动作，并在每次尝试后表达出挫败或中性的情绪。对婴儿反应的分析表明，18 个月大的婴儿，而不是 15 个月大的婴儿，在挫败条件下比中性条件下产生更多的目标动作。这些结果表明，婴儿使用情感交流来消除歧义并模仿他人的意图行为，并且这种能力在生命的第二年发展。
