Abstract

The interindividual variation and test-retest stability of the mismatch negativity (MMN) and N1 components of the event-related potential (ERP) were investigated by presenting standard (85%) and deviant tones (15%) to 10 young subjects in 2 sessions separated by 1 month. Devianttones in different blocks were either frequency or duration changes with interstimulus intervals (ISIs) of 0.5 and 1.5 sec. The results showed a fairly good test-retest stability of the MMN amplitude for both types of changes with each ISI at the group level. The amplitude of the duration MMN showed significant individual test-retest stability. The N1 amplitude showed high stability at both the group and individual levels. Both the MMN and N1 showed considerable interindividual variation. The results suggest that MMN and N1 can be used in follow-up studies not only at the group level but possibly at the individual level also.
