Fig. 3.

Interindividual variability of the ACC sulcal pattern of the children (A) and IC efficiency in the children with asymmetrical and symmetrical ACC sulcal patterns at age 5 (B) and at age 9 (C). (A) 3-D mesh-based reconstructions of the cingulate sulcus (turquoise) and PCS (blue) of each child at age 5 are depicted on the same gray/white interface after being linearly aligned in a common referential (MNI-space). (B) and (C) Mean Stroop interference scores at age 5 (on the Animal Stroop task) and at age 9 (on the Color-Word Stroop task) in children with symmetrical (single or double parallel type in both hemispheres; n = 11) and asymmetrical (single type in the right hemisphere and double type in the left hemisphere or vice versa; n = 7) ACC sulcal patterns. Children with asymmetrical ACC sulcal patterns at age 5 had lower Stroop interference scores than children with symmetrical ACC sulcal patterns at age 5, t(16) = 3.07, p = .0004, d = 1.49, and at age 9, t(16) = 2.85, p = .006, d = 1.38. Error bar denotes standard error of the mean (SEM); *p < .05. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
