Note. The four nap conditions were dummy coded. Three models were estimated, each with the parent collected no-nap (No-Nap-P), experimenter collected morning nap (Morning Nap-E), or parent collected afternoon nap (Afternoon Nap-P) as a reference condition in order to evaluate all pairwise comparisons among the four cortisol profiles.
