Figure 4
Associations between the posterior mean estimates of aDDM parameters and the proportion of choices of the option with the higher EV—i.e., decision quality—displayed for data and estimates from all choice problems concurrently (left subplot), as well as separately for risky.better problems (middle subplot) and safe.better problems (right subplot). Each subplot includes the posterior mean estimate and corresponding 95% posterior interval of the β-coefficient representing the link between a given aDDM parameter and decision quality obtained in the Direct Effect Model for the respective aDDM parameter and (sub-)set of data (see also Table 2). (a) Association between the aDDM’s boundary separation parameter α and decision quality. (b) Association between the aDDM’s distorted processing parameter θ and decision quality.
