Variables	BIC		Quadratic coefficient of quadratic equation	Effect size of water content
	Linear	Quadratic		η2	95% CI
Disgust	26.41	6.78	–431.546	0.091	0.001–0.146
Avoidance	23.07	–6.19	–358.717	0.062	0.000–0.105
Contamination	24.98	6.89	–395.479	0.139	0.029–0.205

BIC is Bayesian Information Criterion of linear and quadratic equations for each variable. The quadratic coefficient of quadratic equations and η² are shown for summarizing the shapes of the quadratic curve.
