Figure 3
Associations between numeracy and each of the process-level measures, and how they depend on the type of choice problem. Solid (dashed) lines represent the associations in risky.better (safe.better) problems. The β-coefficients and 95% posterior intervals for the effects of numeracy, problem type, and their interaction on each of the process-level measures are reported in Table 1. (a) Association between attention allocation, i.e., the proportion of time attending to the option with the higher EV relative to time attending to any option, and numeracy. Each dot (triangle) represents the average attention allocation score in a given participant in the risky.better (safe.better) problems. (b) Association between the aDDM’s distorted processing parameter, θ, and numeracy. Each dot (triangle) represents the posterior mean estimate of θ in a given participant in the risky.better (safe.better) problems. (c) Association between the aDDM’s boundary separation parameter, α, and numeracy. Each dot (triangle) represents the posterior mean estimate of α in a given participant in the risky.better (safe.better) problems.
