Unlike at T1 and T2, there were few findings for the behavioral measure of persistence, although the few findings obtained were consistent with the larger pattern of findings. This measure may be a better index of EC at young than at older ages (the average correlations of this measure with teachers’ and parents’ reports of attention shifting, focusing, and inhibitory control at T1, T2, and T3 were .23, .16, and .12), although it still grouped with measures of EC on a latent factor for children approximately the age in this study (Valiente et al., 2003).
