Infants recognize similar goals across dissimilar actions involving object manipulation

We investigated infants' ability to recognize the similarity between observed and implied goals when actions differed in surface-level motion details. In two experiments, 10- to 12-month-olds were habituated to an actor manipulating an object and then shown test actions in which the actor contacted the object with a novel hand configuration that implied a goal either similar or dissimilar to the habituation event. Infants in both experiments looked significantly longer at test actions depicting a novel implied goal, suggesting that infants glossed over some surface-level motion details and compared implied goals.
