Scatter plots, histograms, and correlations for age, IQ, accuracy and mean RT, and diffusion model parameters, nondecision time, boundary separation, and drift rate averaged over conditions for the lexical decision and item recognition tasks. acc=accuracy, RT=mean RT, a=boundary separation, Ter=nondecision time, v=mean drift rate, Lex is the lexical decision task, and Rn is the item recognition task.
