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.
