Altered probabilistic learning and response biases in schizophrenia: behavioral evidence and neurocomputational modeling.

OBJECTIVE Patients with schizophrenia (SZ) show reinforcement learning impairments related to both the gradual/procedural acquisition of reward contingencies, and the ability to use trial-to-trial feedback to make rapid behavioral adjustments. METHOD We used neurocomputational modeling to develop plausible mechanistic hypotheses explaining reinforcement… CONTINUE READING
