Models predicting the decision to reveal an answer and associated BIC scores of each model

Model formula	Exp1: BIC	Exp1: AIC	Exp 2: BIC	Exp 2: AIC
$\text{Decision}=b_1\ast \text{curiosity}+b_2\ast \text{importance}$	936.4	912.8	930.0	906.9
$\text{Decision}=b_1\ast \text{curiosity}$	937.2	923.1	917.6	903.7
$\text{Decision}=b_1\ast \text{curiosity}+b_2\ast {\text{confidence}}^2+b_3\ast \text{confidence}$	951.5	918.5	918.5	876.0
$\text{Decision}=b_1\ast \text{curiosity}+b_2\ast {\text{confidence}}^2+b_3\ast \text{confidence}+b_4\ast \text{importance}$	967.1	905.8	929.4	869.2
$\text{Decision}=b_1\ast {\text{confidence}}^2+b_2\ast \text{confidence}+b_3\ast \text{importance}$	984.4	951.5	906.8	874.4
$\text{Decision}=b_1\ast \text{importance}$	996.8	982.6	955.3	930.4
$\text{Decision}=b_1\ast {\text{confidence}}^2+b_2\ast \text{confidence}$	1067.5	1048.7	923.7	905.2

Lower BIC scores indicate better model fits. BIC scores of Experiment 1 (Exp. 1) are ranked in ascending order (from lowest to highest). The best fitting models with respect to BIC are marked in bold
