Within-individual and between-individual variance components (mean-corrected) estimated from bootstrapping (N = 1000) in the package rptR. Mean and standard error is shown. Baseline cortisol, cortisol responsiveness after 1 h, and cortisol responsiveness after 2 h did not significantly differ in the between-individual variance component. Within-individual variance was significantly higher in baseline cortisol than in cortisol responsiveness after 1 and 2 h
