Figure 9.

Scatterplots plotting individual parameter estimates against PIQ. Maximum likelihood estimates contained within the posterior for each participant's mean drift rate across difficulty levels (v.mean), boundary separation (a), nondecision time (ter), difference in drift rate between difficulty levels (v.diff), and starting point (z/a), plotted as a function of PIQ, for the motion coherence task (left column) and direction integration task (right column). Gray represents typically developing children. Blue represents children with dyslexia.
