ALL_DATA.data contains 27 cells: one cell per participant. Each cell has 8 columns, containing the following information for each of 800 trials (also indicated in ALL_DATA.fields): - Treatment Order (0 = placebo in session 1/atomoxetine in session 2; 1 = atomoxetine in session 1/placebo in session 2) - Treatment (0 = placebo, 1 = atomoxetine) - Noise: SD of the number-generating distribution (10 or 25) - Absolute prediction error - Learning rate - Change-point probability, according to the normative model - Relative uncertainty, according to the normative model - P3 Amplitude
