ABSTRACT

The current study investigated the development of rational imitation in 14-month-old Korean infants using Gergely et al. (2002)’s procedure. We also examined the relationship between infants’ rational imitation and their temperament. The infants watched an actor use her head to illuminate a light box while her hands were free (Hands-free condition) or while her hands were occupied by a blanket (Hands-occupied condition). The infants in the hands-free condition were more likely to imitate the actor’s head action than the infants in the hands-occupied condition. In the hands-free condition, the frequency of head reenactment negatively correlated with infants’ negative emotionality and the latency of head reenactments negatively correlated with the duration of orienting in infants. These results indicate that 14-month-old Korean infants can infer the goals of others’ actions by considering situational constraints and that individual differences in rational imitation can be related to differences in infants’ temperament.
