Also, several lines of evidence suggest a similarity between schizophrenia and schizotypal personality disorder (SPD). This study was undertaken to determine the replicability of our previous finding of a left-lateralized P3 amplitude deficit in SPD. Methods: We recorded event-related potentials in 21 SPD and 18 normal control subjects in an auditory “oddball” P3 paradigm. Results: In the SPD subjects, but not in the control subjects, there was lower P3 amplitude at T3 compared with T4. Conclusions: These results are similar to the ones in our previous work and further support the presence of a left-lateralized P3 deficit in SPD.en-USSPDP300schizophreniaauditory oddballJournal Article2016-09-1510.1016/S0006-3223(00)00938-0
