Resp., response; EWA, experience-weighted attraction model; phi, learning rate; rho, experience decay; beta, inverse temperature. Data were analyzed using a multivariate GLM, including age and chlorpromazine equivalent dose (for which there were no significant relationships with behavior) and are expressed as direction of association (Partial Eta Squared). *p < 0.05; **p < 0.01
