The current thesis focuses on auditory processing during the crucial school-age years, utilizing event-related potentials (ERPs) and fields (ERFs) to examine obligatory tone frequency processing and deviancy detection in children and adults. Initial findings reveal significant differences in ERPs between children and adults, although the underlying generators and functions may be similar. The first experiment addressed this issue, while the subsequent experiments explored maturational changes in discriminative processing abilities, particularly auditory deviancy detection as indicated by mismatch negativity (MMN). It is posited that ERP indices for obligatory tone processing (N1) and deviancy detection (MMN) are closely related. A novel paradigm was developed to differentiate these processes. Key findings highlight that obligatory auditory stimulus processing occurs in similar cortical areas for school-age children and adults, with mature frequency representations evident by ages nine to ten. However, deviancy processing does not appear fully matured by mid school-age using adult paradigms. When auditory input is tailored for children (e.g., slower pace, salient distractors), deviancy detection can align more closely with adult performance, although salient distractors may require additional processing steps. Overall, the study demonstrates that a controlled experimental paradigm can effectively disentangle obligatory and devi
