Separate time course graphs (left) for Experiments 1 and 2 depicting trials in which infants looked longer at the to-be-changed item or the non-changing item during the prechange phase and graphs for each kind of trial (right) depicting the median of mean change preference scores collapsed over the entire preference score window. In the collapsed data, each circle represents the preference score from a single infant. The black line within the cloud of circles indicates the mean of the median preference scores, with the 95% confidence interval shown by the gray error bars.
