Mean (SE) false alarm rate on AY and BX trials for control, proband, and relative groups. Proband groups had comparably elevated false alarm rates overall compared to controls, and schizoaffective probands had modestly elevated false alarm rates compared to bipolar probands. Relative groups’ false alarm rates did not differ from controls or one another. False alarm rates were higher on AY (response inhibition) relative to BX (goal maintenance) trials for all groups except for schizophrenia and schizoaffective probands who had comparable false alarm rates on both trial types. Scz = Sczhizophrenia; SczA = Schizoaffective; BP = Psychotic Bipolar.
