Developmental changes in P300 wave elicited during two different experimental conditions

Event-related potentials in clinical research: Guidelines for eliciting, recording, and quantifying mismatch negativity, P300, and N400

“…Auditory P300 has a centro-parietal distribution that increases in amplitude and decreases in latency (Martin et al, 1988;Ladish and Polich, 1989) steadily from age 5 to age 19. This pattern is observed for both active and passive oddball tasks (from 1 to 21 years: Fuchigami et al, 1995). In contrast, both the amplitude and latency of visual P300 appear to decrease from age 10 to age 21 (Katsanis et al, 1996; but see Ridderinkhof and van der Stelt, 2000).…”

Maturation of mismatch negativity and P3a response across adolescence

“…We further predict that P3a measured from difference waveforms would decrease in amplitude across adolescence. We could not predict changes in P3a latency due to contradictory outcomes from existing studies [12,21]. The present study aims to provide a more accurate description of P3a development across adolescence by grouping large numbers of adolescents into 1-year age groups.…”

“…The stimuli were separated by a jittered stimulus-onset asynchrony (SOA) of 0.9-1.1 s to minimize the confounding effect of ERP artifacts related to anticipation of a stimulus and overt attention [22]. The stimuli had a stimulus duration of 175 ms in order to (1) meet the standard guidelines to record MMN [24], and (2) facilitate adequate comparison with previous studies of maturation of MMN and P3a in adolescents [11,12,21]. …”

“…Interestingly, they also found an increase in P3a amplitude with age when P3a was measured from deviant and target ERPs, but a decrease in P3a amplitude with age when P3a was measured from difference waveforms (i.e., when ERPs to standard stimuli were subtracted ERPs to deviant stimuli or to target stimuli). Finally, Fuchigami et al [21] looked at the development of P3a latency between 4-21 years, and reported no change in P3a latency across adolescent participants of their study. Unfortunately, this study did not consider P3a amplitude.…”

Age-changed normative auditory event-related potential value in children in Taiwan

“…2 The results of this study showed that the components of auditory ERPs vary in a systemic pattern in children between the ages of 6 and 13 years. Although ERPs have been studied in children younger than 6 years, 27 we excluded participants younger than 6 years because the greater latency variability in younger children may confound our data analysis. Our data are consistent with the results of previous studies showing that P3 and N2 latencies decrease with age.…”
