Unexpectedly, mother-rated SL (vs. IM) status was predicted by low parent-reported attention and inhibitory control and observed persistence in 3 of 10 analyses. There were no findings for impulsivity, and only 1 finding (out of possible 8) for negative emotion (and this finding for anger was contrary to expectation). However, as indicated in Table 7 with footnotes, the findings for parent-reported attention, inhibitory control, and anger were due to the predictor (temperament) relating to change in maladjustment in reversed directions at T1 and T3; these T3 relations were no longer significant when the T1 predictor was not used as a covariate. Thus, it appears that those three findings were suppression effects.
