By contrast, W1 parent-rated boldness did not contribute significantly to prediction of W3 nonaggressive ASB over/above W1 anticipatory or noise-elicited SCR, which evidenced near-significant ( p = .05) and significant relations, respectively, as individual predictors.
In the corresponding analysis for participant-rated nonaggressive ASB, on the other hand, the predictive contribution of anticipatory SC at step 1 bordered on significance, F (1, 626), = 3.73, p = .05 ( B = -.08), whereas the incremental contribution of W1 parent-rated boldness at step 2 (Δ R 2 = .005) was nonsignificant, F (1, 625) = 3.22, p = .07 ( B = .07).
The corresponding main effect for W1 parent-rated boldness in the analysis for SCR to the noise blast itself was in the same direction, with children who exhibited less SCR to the noise blast across signaled trials tending to score higher in parent-rated boldness at W1 ( r = -.06), but fell short of significance, F (1, 1,080) = 3.54, p = .06.
A similar association was found for SCR to the occurrences of the noise blasts (i.e., children exhibiting less reactivity to the blasts across the three signaled trials were rated as higher in boldness by their parents), although this association was somewhat weaker and fell just short of significance.
Paralleling its concurrent relationship with parent-rated boldness at Wave 1, W1 anticipatory SCR as a whole (i.e., across the three signaled trials) evinced a negative correlation with W3 parent-rated boldness, though this correlation was weaker and did not achieve significance.
