Exemplar table of a final model showing the estimated coefficients for asymmetries in the maximum temperature of the Inner corner of the eyes (L-R) calculated using linear multilevel models (n = 36 calves × 6 recording sessions; 216 images in total), showing the effect of reaction to the researcher (df = 3), using “not moving” as the reference category

Variable	Categories	Coefficient	S.E.	p-value	Asymmetries towards	Active hemisphere (hypothesised)
Constant	n/a	–0.026	0.056	P = 0.649
Reaction to the researcher	Moving away	0.167	0.126	P = 0.187
	Approaching	–0.341	–0.613	P = 0.014	Right eye	Left hemisphere
	No movement
	Restrained calves on the disbudding session	–0.106	0.180	P = 0.555

Tables for the rest of the models can be found in the Supplementary material.
