WAIC for all tested models in experiment 1

Model	T1		T2
	WAIC	Difference from the best model	WAIC	Difference from the best model
Full model	12,102.985	3.49	28,440.68	0.00
Constant σ across object	12,102.09	2.60	28,441.14	0.46
Constant PM across object	12,101.155	1.67	28,468.22	27.54
Constant σ and PM across object	12,099.49	0.00	28,507.22	66.54

In the full model, both P^M and σ^o parameters vary across object conditions, in the constant σ and constant P^M, one parameter (P^M or σ^o) was constant, while the other parameter varied across object conditions, and only the varying parameter was freely estimated for each object condition. In the Constant σ and P^M model, both parameters were constant across object conditions and a single P^M and σ were estimated across object conditions. Lower values indicate better fit and the best model is printed in bold
