Figure 3.

Learning trend in the experimental task. The panel on the left shows the individual fits obtained by the entire sample of 137 children. Twelve fits showed an R²<0.3, and the data were excluded from further analyses. The panel on the right shows the fit applied to the median of the data of the remaining sample of 125 children (red solid line) with an R²=0.95 and the 95% confidence intervals (black lines). The bars on the far right show the medians and standard deviations of the two retest conditions (B1=118, SD=32; B2=89, SD=24).
