Zusammenfassung:ABSTRACT Event‐related potentials (ERPs) were recorded in a cross‐sectional study from 70 adolescents ranging in age from 11 to 18. A paradigm was used in which background, standard auditory events (66 percent occurrence) were randomly replaced by either a change in pitch, or a missing stimulus, each occurring 17 percent of the time. Subjects were instructed to respond to one of the infrequent events, with each designated as relevant (i.e., a target) on alternate blocks of trials. Factor score analyses showed that P300 and frontal negative slow wave were larger to relevant than irrelevant events, whereas parietal positive slow wave was not. Both N200 and frontal negative slow wave showed modest age effects. Significant effects of sex, mainly for the exogenous components, were also found. These data highlight the importance of the negative task‐related potentials as correlates of development. They also point to the functional independence of P300 and slow wave and add to the evidence for the functional distinction between the frontal negative and parietal positive aspects of slow wave.
