Model comparison for the effect of 5-HTR blockade on the relationship between error rate and RT in the reward-size task (for S4 Fig).

a(mk), a(cond), e(mk), and e(cond) indicate the random effects of 5-HT depletion on parameters a and e, respectively. The probability distribution of the random effects were as follows: a_cond and a_mk were ~N(0,σ²_cond) and ~N(0,σ²_mk), respectively. (a’_cond, e’_cond) and (a’_mk, e’_mk) were ~biNorm(0, ∑_cond) and ~biNorm(0, ∑_mk), respectively. E, error rate; RT, reaction time; mk, monkey; cond, treatment condition (antagonist or control). BIC is a relative measure of quality for the models. ΔBIC denotes the difference from the minimum BIC.
