StoPCNA1 and StoPCNA3 interacted with each other, so did StoPCNA2 and StoPCNA3, but no interaction between StoPCNA1 and StoPCNA2 was observed.
There was an effect of sire (P < 0.01) on P/AI, but no interaction between sire and time of AI (P = 0.88).
The cloacal gland area was significantly affected by the sex and embryonic treatments of the birds but no interaction between the two factors was found (see details in Fig. 3 legend).
A main effect of target gender showed that men were judged to appear taller than women, F 1, 14) = 26.50, p<.001, but no interaction between gender and status cues emerged, F 2, 28) = 0.44, ns.
The analogous ANOVA for anterior ROIs indicated significant effects of chord (F (2,38) = 2.96, p<0.05, tested one-sided according to our hypothesis) and of expression (F (1,19) = 7.27, p<0.02), but no interaction between factors chord and expression (p = .17).17
The analysis of MRI data revealed a significantly faster reduction of infarct volumes by the treatment with PPADS (F1,31 = 12,192; P = 0,001) and a general reduction dependent on the day of measurement (F1,31 = 108,838; P<0,001) but no interaction between treatment and day.
We also included the Beck Depression Inventory-II score as a covariate in a separate ANOVA but observed no interaction between depression and drug effects.
For V5/MT, phosphene INTENSITY showed a significant main effect of laterality (F 1,23 = 9.57, P = 0.005) and phase (F 2,22 = 3.53, P < 0.05) but with no interaction between laterality and phase.
A different study, investigating binding to both Bax and Bak, found that BimS IP with Bax but found no interaction between Bak and the BH3-only proteins, consistent with our results.
A significant effect of year (p<0.01) emerged for all positions, but no interactions between year and judge were found (all p>0.05, as described in detail below).
Switch costs between target categories were larger for conjunction than feature foraging, but there was no interaction between age and switch costs, so they are relatively stable during those years and mirror the results from adults (Jóhannesson et al., 2016).
