Reliability of the contingent negative variation and the auditory evoked potential.
Contingent negative variations (CNVs) composed of 32 trials had a median subject consistency of 0.68 in retests separated from 5 min to 7 days. Hand measurement of the CNV was highly reliable with a median reliability of 0.96. Subject consistencies for the amplitudes and latencies of N1 and P2 components of a auditory evoked potential (AEP) had a median of 0.59 when 265 trials were averaged. These consistencies for N1 and P3 components had a median of 0.45 when only 16 trials were averaged. Median measurement reliabilities for the AEP were 0.92 for amplitudes and 0.66 for latencies.
