  1. Bayesian information criterion (BIC) measures are summed for fits for each participant’s first play (N = 26,720). Both models included choice stochasticity (inverse temperature) and loss aversion parameters. The final column is the difference between the model BIC and BIC for the Dual Alpha model.
