The effect of age on the executive index. For each participant, the median reaction time, adjusted for error, of trials with congruent flankers is subtracted from the median-adjusted reaction time of trials with incongruent flankers. This executive index differs in an age-dependent fashion between those with 22q11.2DS and typically developing control participants. The variation within groups appears most prominent at the younger ages (80 months) for both groups. Group performance converges at adolescence. A fit line with 95% CI is shown for the typically developing group, but is omitted for children with 22q11.2DS where a line does not describe the distribution of their raw performance by age
