In both experiments, running it this way resulted in highly significant negative effects of ΔCue and ΔTarget (both p < 0.001), but positive effects of ΔCue*ΔTarget ( p < 0.001), presumably because after accounting for the negative independent predictions of both ΔCue and ΔTarget, ΔCue*ΔTarget values actually were better than expected.
We found that interdependence significantly increased with relatedness in the 48 hr experiments [both, r 2 (44)>0.11, p<0.02], and this was marginally significant in the 5 min experiments [both r 2 (44)<0.06, 0.07<p < 0.08] ( Figure 3B ).
These results differ somewhat from our prior paper ( Antony et al., 2022b ), which showed similar facilitation in the ΔCue condition, but in which most correlations between memorability and relatedness were positive yet fell short of significance.
