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

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.

每一列均展示均值，标准差标注于括号内。各组间差异的显著性标注于表格右侧：对应列中的星号（从左至右依次为：LOT-R；定义先验（prior）分布中心的α/(α+β)；软最大化（softmax）决策参数γ）表明，在针对乐观者与悲观者的t检验中，对应的p值小于0.05。
