Values presented as mean (standard deviation). BDP = bipolar disorder with psychosis; BDNP(−) = bipolar disorder without psychosis without first-degree family history of psychosis; BDNP(+) = bipolar disorder without psychosis with first-degree family history of psychosis; PS = paired- stimulus waveform; TGT1 = target waveform 1 (parietally distributed); TGT2 = target waveform 2 (frontally distributed); STD = standard waveform.
