Affect-congruent attention modulates generalized reward expectations

Estimated posterior distributions for group-mean parameters.
Top histograms: group-level means for the parameters αV (A), ϕ (B), and β (C). Bottom histograms: group level means for the effect of affect on αV (D), the effect of affect on ϕ (E), and the block-wise decay in the strength of these effects, λ (F). Horizontal error bars denote the 90% credible interval for each parameter, and vertical dotted lines denote the reference value for each parameter (i.e., the parameter value at which there is no influence of the parameter on behavior: 0 for additive parameters such as αV, 1 for parameters that were multiplicative or exponents such as ϕ and λ). Asterisks denote parameters for which there is credible evidence (i.e., estimated probability in excess of 95%) that the group mean is different from the reference value.
