Simple moving averages for hit rate are provided for two age groups of children: 2-year-olds (dashed line) and 3- to 7-year-olds (solid line). Shading represents the 95% credible interval around the mean: red for 2-year-olds and gray for 3- to 7-year-olds. Trial number corresponds to the proportion of trials the child–observer team were correct, calculated over the current trial and the nine preceding trials for each group. For example, Trial 15 is the proportion correct among Session Trials 6–15. yr = years.
