Fig. 3From: The effect of 5-HT1A receptor antagonist on reward-based decision-makingModel fitting of choice behavior in the drug and the control conditions. To estimate the reward value of each choice target, the monkeys’ choice probability was fit by the exponential discounting model (Eq. 2). Points are the actual choice probability in each combination of choice targets. Lines are the estimated choice probability by model fitting (Eq. 4)Back to article page
