Mean ± SE across blocks for CR and UR primary dependent variables. (A) Comparison of Percent CRs for schizophrenia and healthy control groups. Both groups showed evidence of learning, as indicated by an increase in CR incidence as the experiment progressed, but the schizophrenia group had fewer CRs throughout the experiment. (B) Comparison of CR Peak Latency for schizophrenia group compared to healthy controls. Schizophrenia patients had faster CR latencies than healthy controls, indicating less adaptively timed responses. (C) Comparison of UR peak amplitude for healthy control and schizophrenia groups. Amplitude decreased for both groups as the experiment progressed, but the schizophrenia group had larger amplitudes compared to the healthy control group. (D) UR peak latency across blocks in schizophrenia and healthy control groups. UR latency decreased for both groups with experience, but the schizophrenia group had significantly slower UR latencies.
