Left: Patients with schizophrenia had significantly smaller N1 than controls in response to words at encoding, as seen in the waveform plot at left. This was in part explained by the interaction between participant group and N1 in predicting later free recall performance. Right: As shown in the scatterplot at right, “smaller” (i.e., less negative) encoding N1 amplitudes predicted better free recall performance in the patient group while a “larger” encoding N1 predicted better recall in controls.
