Akaike Weights for Each Computational Model

WSLS Softmax Baseline
Reward-Maximization
Non-Depressed 0.28 (0.06) 0.70 (0.06) 0.02 (0.02)
Depressed 0.29 (0.06) 0.71 (0.06) 0.00 (0.00)
Punishment-Minimization
Non-Depressed 0.38 (0.07) 0.64 (0.06) 0.07 (0.04)
Depressed 0.31 (0.06) 0.64 (0.07) 0.02 (0.02)

Note: Higher Akaike weights indicate a better fit to the data. Standard errors of the mean are listed in parentheses. WSLS refers to the Win-Stay-Lose-Shift computational model.
