All sessions were videotaped and coded offline. The footage from individual trials was spliced so
that each child’s enactment was separated from the experimenter’s model. Coders viewed only the
children’s enactments and, therefore, were completely blind to the particular event that had been previously
demonstrated. Trials were coded for the manner, path, and goal that each child used in his or
her enactment. The manner was coded as hopping if the figure broke contact with the surface of the
ramp and as sliding if the figure maintained contact with the ramp. The path was coded as up the child
moved toy up the ramp and as down if the child moved the toy down the ramp.
