  • Abstract
  • Look Inside

 ERPs were recorded, with simultaneous measurement of RTs, from schizophrenics with mild symptomatology and normals during a 3-tone auditory paradigm. Performance levels and P3 latencies were nearly equal in both groups. However, RTs in schizophrenics were delayed by approximately 90 msec as compared to normals. Correlation between P3 latencies and RTs were lower in schizophrenics than in normals. Above results seem to originate from some deficits in a higher organizing system in schizophrenics.
