We found that EEA had reasonable rank-order stability as kids developed (with over a year between visits!) and had robust links to both brain activation and behavior. (You’ll see SDRT on the brain picture — it performs pretty well too ☺️)

Following Alex Weigard’s work in adults, we used latent factor modeling to generate a task-general Efficiency of Evidence Accumulation (EEA) from condition-specific drift rates. EEA indexes how efficiently a person can make correct decisions among noise.
