Plasma cortisol concentrations (ng/mL) function of oral (A) and motor (B) stereotypic behaviours frequencies in horses from riding schools (study 1, N = 55). Plasma cortisol concentrations were assessed two times per horse (between 18:00 and 19:00) and averaged. Original data are presented for clarity (plasma cortisol concentrations were Box Cox-transformed and stereotypic behaviours were log-transformed for analysis). Neither oral nor motor stereotypic behaviours frequencies predicted plasma cortisol concentrations (respectively F 1, 48 = 1.11, P = 0.30 and F 1, 48 = 0.86, P = 0.36).
