For EC, 3 of 10 findings were significant (and 2 more were near significant). Both mother- and/or teacher-reported IM (vs. SE) status was predicted by high attention and inhibitory control. SE was also predicted by impulsivity (2 of 4 effects were significant), anger (2 of 4 analyses), and sadness (in 2 of 4 analyses), all within reporter. In addition, unexpectedly, mother-designated IM status was predicted by teacher-reported sadness (a finding that disappeared when we controlled for internalizing). Thus, designation as an IM, in comparison to designation of a SE, generally was associated with high regulation and relatively low impulsivity, anger, and sadness.
