Free play session
The children’s spontaneous play during the initial free play session was analyzed to see whether
there were any a priori biases toward enacting any of the event components. A total of 68% (n = 23)
of the children spontaneously enacted any of the components that would later be used in the study.
These participants clearly showed a goal bias, with 82.6% (n = 19) of them including play with a goal
object, placing the doll either in or on one of the bowls.
