Abstract

Event-related potentials were recorded from participants 5-7, 9-11, 14-16, and 22-28 years old during an auditory novelty oddball task. In this task, stimuli about which the participant is not instructed (i.e., novel or uncategorized) typically elicit a more frontally oriented P3 scalp topography (novelty P3). In contrast, stimuli to which the participant must respond (i.e., target or precategorized) elicit a P3 with a more posterior scalp topography. Repetition of identical novel stimuli led to a similar reduction in novelty P3 amplitude for all age groups. Moreover, with repetition the shift in scalp topography of the novelty P3 to a more parietally oriented distribution was similar in children and adults. A second component, the P3(2) (assumed to be an analog of the P3b), exhibited a repetition priming effect in both the adults and the youngest children. The fact that age-related differences induced by novel repetition were small and not systematic indicates that the processing of novel information is similar across a wide age range.
