One-year test-retest reliability of auditory ERPs in young and old adultsKristine B Walhovd
University of Oslo, Institute of Psychology, PO Box 1094 Blindern, 0317 Oslo, Norway
Int J Psychophysiol 46:29-40. 2002..In general, the old group exhibited weaker P3 peak latency reliabilities than the young group.
