Best-fitting parameters for the Bayesian model summarized per experiment and averaged for the entire group of subjects and per subgroup (optimists and pessimists).

<p>Each column presents the mean value, with the standard deviation between brackets. Significance of the differences is shown on the right of the table: an asterisk in the corresponding column (left to right: LOT-R; α/(α+β) which defines where the prior is centered; γ is the softmax decision parameter) indicates a p value less than 0.05 for a t-test between optimists and pessimists.
