Knowing who dunnit: Infants identify the causal agent in an unseen causal interaction.

Preverbal infants can represent the causal structure of events, including distinguishing the agentive and receptive roles and categorizing entities according to stable causal dispositions. This study investigated how infants combine these 2 kinds of causal inference. In Experiments 1 and 2, 9.5-month-olds used the position of a human hand or a novel puppet (causal agents), but not a toy train (an inert object), to predict the subsequent motion of a beanbag. Conversely, in Experiment 3, 10- and 7-month-olds used the motion of the beanbag to infer the position of a hand but not of a toy block. These data suggest that preverbal infants expect a causal agent as the source of motion of an inert object.

Five-month-old infants know humans are solid, like inanimate objects.

Infants know that humans are exempt from some of the principles that govern the motion of inanimate objects: for instance, humans can be caused to move without being struck. In the current study, we report that infants nevertheless do apply some of the same principles to both humans and objects, where appropriate. Five-month-old infants expect humans, like all material objects, to be solid.
